600 A 15/25 kV Class
Bol-T™ Deadbreak Connector
GENERAL
The Cooper Power Systems 600 A,
15/25 kV Class Bol-T™ Deadbreak
Connector is used to terminate highvoltage underground cable on
deadfront apparatus such as transformers, switches and switchgear. It is fully
shielded, submersible and meets the
requirements of IEEE Standard 386™
– “Separable Insulated Connector
Systems”.
The capacitive test point on the
insulating plug provides a means of
testing the circuit without disturbing
the bolted connection.
In addition to the capacitive test point
feature on the insulating plug, Cooper
Power Systems offers an optional
capacitive test point similar to the test
points on Cooper 200 A Elbows. This
allows the use of the Type “TPR”
Series Fault Indicators, and provides a
hotstick operable means of determining
circuit condition when used with high
impedance voltage sensing devices
designed for test points.
Bol-T Connectors are designed for
use on solid dielectric cable (XLPE or
EPR) with extruded semi-conductive
shields and concentric neutral, with or
without a jacket.
Installation on jacketed concentric
neutral cable may require additional
sealing material. Cold shrinkable
adapters are available for tape shield,
linear corrugated and drain wire cable
adaptation for use with deadbreak
connectors.
900 AMP RATING
The Bol-T is rated for 900 A continuous
when used with a coppertop compression connector, copper insulating
plug, copper stud and copper bushing
or junction. If a 900 A rating is desired,
specify a “C” as the 9th digit when
determining your part number.
See Step 3, page 4.
INTERCHANGEABILITY
All Cooper Power Systems 600 A
Deadbreak Connectors conform to the
electrical, mechanical and dimensional
requirements of IEEE Standard
386™. The connectors can be used
on any comparably rated bushing interface that also meets the requirements
of this standard. In addition, all cable

adapters, insulating plugs, compression
connectors and other component parts
are designed to be interchangeable
with those currently available from all
other manufacturers that also comply
with IEEE Standard 386™.
INSTALLATION
A torque wrench and one-inch socket
are used to tighten the insulating plug
through the compression connector
within the T-Body onto a de-energized
600 A bushing interface. Refer to
Installation Instruction Sheet 600-10-2

GENERAL
The Cooper Power Systems 600 A,
35 kV Class Bushing Adapter is used
to convert a standard 600 A deadbreak interface to a standard 200 A
loadbreak interface. It meets all the
requirements of IEEE Standard 386™
— “Separable Insulated Connector
Systems”.*
The 600 A, 35 kV Class Bushing
Adapter is a factory assembled
Loadbreak Reducing Tap Plug (LRTP)
and Bushing Extender unit. It is used to
convert a 600 A deadbreak interface to
a 200 A loadbreak interface*, allowing
for convenient testing and grounding.
Used with a 200 A insulated protective
cap, M.O.V.E. Arrester, grounding
elbow or loadbreak elbow connector,
a bushing adapter provides a fully
shielded, submersible unit that meets
the requirements of IEEE Standard
386™.*
The LRTP provides a means for live
testing, visibly grounding and separating
of 600 A “T” type terminators. Its 200 A
interface can also be used as a means
of connecting overvoltage arresters
for system protection.
The LRTP features an all copper alloy
current path. No aluminum components
are used. The LRTP’s unique captured
rotating nut feature provides ease of
installation and removal of the connector from the apparatus bushing. This
feature allows for one-person hotstick
operation for all associated components.
INSTALLATION

600 A 35 kV Class
BT-TAP™ Deadbreak Connector
GENERAL
INTERCHANGEABILITY
The Cooper Power Systems 600 A
35 kV Class BT-TAP™ Deadbreak
Connector is used to terminate highvoltage underground cable to
transformers, switches, switchgear and
other apparatus. It is designed for use
with unthreaded compression
connectors to easily retrofit existing
600 A Bol-T™ installations, or in new
installations where a 200 A interface is
required and where the system will not
need to be frequently operated. If the
system will be frequently operated to
sectionalize, or to achieve a visible
break or ground, Cooper recommends
the use of the T-OP™ II Connector
System. (See catalog section 600-52.)
The BT-TAP Deadbreak Connector is
fully shielded, submersible and meets
the requirements of IEEE Standard
386™ – Separable Insulated
Connector Systems.
The 200 A, three-phase rated loadbreak
interface provides a means for obtaining
a direct conductor test, visible ground
and provides a convenient location for
a Cooper M.O.V.E.™ Arrester or
grounding elbow.
Cooper Power Systems offers an
optional capacitive test point similar
to test points on our 200 A elbow
connectors. This allows use of Cooper’s
Type “TPR” Series Fault Indicators,
and provides a hotstick operable means
of determining circuit condition when
used with high impedance voltage
sensing devices designed for test
points.
BT-TAP Connectors are designed for
use on solid dielectric cable (XLPE or
EPR) with extruded semi-conductive
shields and concentric neutral, with or
without a jacket.
Installation on jacketed concentric
neutral cable may require additional
sealing material. Cold shrinkable
adapters are available for tape shield,
linear corrugated, unishield, and drain
wire cables for use with deadbreak
connectors.
All Cooper Power Systems 600 A
Deadbreak Connectors conform to
the electrical, mechanical and
dimensional requirements of IEEE
Standard 386™. The connectors can be
used on any comparably rated bushing
interface that also meets the requirements of this standard. In addition, all
T-bodies, cable adapters, insulating
plugs and compression connectors
are designed to be interchangeable
with those currently available from
other major manufacturers that also
certify their components to IEEE
Standard 386™.
900 AMP RATING
The BT-TAP is rated for 900 A
continuous when used with a coppertop
compression connector and copper
bushing or junction. If a 900 A rating is
desired, specify a “C” as the 10th digit
when determining your part number.
See Step 3, page 4.
March 2003 • New Issue
Printed in U.S.A.
INSTALLATION
The T-body is assembled onto
prepared cable with an unthreaded
compression connector. The short
end of a special copper alloy stud,
provided with the kit, is torqued onto a
de-energized 600 A bushing. Using a
T-WRENCH, the loadbreak reducing
tap plug is threaded onto the stud
drawing the entire assembly tight to
the apparatus bushing. The assembly
is then torqued to the apparatus
bushing using an installation torque
tool. (See Table 5 for information on
tools.) Refer to Installation Instruction
Sheet S600-55-1 for details.

600 A 35 kV Class
PUSH-OP® Deadbreak Connector
600-53
GENERAL
The Cooper Power Systems 600 A,
35 kV Class PUSH-OP® Deadbreak
Connector offers a complete threadless deadbreak, hotstick operable
connection system for terminating
underground cables to transformers,
switches, switchgear, and other apparatus. It is fully shielded, submersible,
and meets the requirements of IEEE
Standard 386™ – Separable
Insulated Connector Systems.
The design employs a unique, 600 A
rated, plated copper probe and
mating PUSH-OP Bushing utilizing a
plated copper finger contact system.
PUSH-OP's stainless steel latching,
linkage mechanism provides leverage
for easy disconnection of the
terminator and easy handling of heavy
cable. The result is a one-person,
hotstick operable connection system
that is unequalled in ease of operation
and time required to perform
sectionalizing operations.
A coppertop compression connector is
provided for terminating the conductor.
The 200 A three-phase rated loadbreak
interface provides a means for
obtaining a live test, visible ground
and visible break using a hotstick. It
also provides a convenient location for
a Cooper M.O.V.E. Arrester or
Grounding Elbow. The grounding
elbow may be continuously connected
to the PUSH-OP while moving it to and
from an apparatus bushing.
Cooper Power Systems offers an
optional capacitive test point similar to
test points on 200 A elbow connectors.
This allows use of Type S.T.A.R.™
(TPR) Series Fault Indicators.
The PUSH-OP also has a non-bolted
connection that eliminates threading
and its associated problems.

PUSH-OP Connectors are designed
for use on solid dielectric cable (XLPE
or EPR) with extruded semi-conducting
shields and concentric neutral, with or
without jacket. Installation on jacketed
concentric neutral cable may require
additional sealing material. Cold
shrinkable adapters are available for
tape shield, linear corrugated and
drain wire cable adaption for use with
deadbreak connectors.
INSTALLATION
The T-body housing with stainless
steel shroud is assembled onto
prepared cable with a threaded
coppertop spade lug compression
connector. The loadbreak reducing
tap plug is threaded into the connector
and onto a probe using an alignment
tool, installation torque tool, and
T-wrench.
The assembled housing is then
connected to a de-energized 600 A
PUSH-OP type bushing interface and
bracket using hotline equipment
without any threading operation.

GENERAL
The Cooper Power Systems 600 A,
35 kV Class Bol-T™ Deadbreak
Connector is used to terminate highvoltage underground cables to deadfront apparatus such as transformers,
switches and switchgear. It is fully
shielded, submersible, and meets
the requirements of IEEE Standard
386 – Separable Insulated Connector
Systems.
The capacitive test point on the
insulating plug provides a means of
testing the circuit without disturbing
the bolted connection.
In addition to the capacitive test point
feature on the insulating plug, Cooper
Power Systems offers an optional
capacitive test point similar to the
test points on Cooper’s 200 A elbows.
This allows the use of the Type “TPR”
Series Fault Indicators, and provides a
hotstick operable means of determining
circuit condition when used with high
impedance voltage sensing devices
designed for test points.
Bol-T Connectors are designed for
use on solid dielectric cable (XLPE or
EPR) with extruded semi-conductive
shields and concentric neutral, with or
without a jacket.
Installation on jacketed concentric
neutral cable may require additional
sealing material. A special grounding
adapter is available for tape shield,
linear corrugated, unishield, and drain
wire cables for use with deadbreak
connectors.
900 AMP RATING
The Bol-T is rated for 900 A continuous
when used with a coppertop compression connector, copper insulating
plug, copper stud and copper bushing
or junction. If a 900 A rating is desired,
specify a “C” as the 9th digit when
determining your part number.
See Step 3, page 4.
INTERCHANGEABILITY
All Cooper Power Systems 600 A
Deadbreak Connectors conform to the
electrical, mechanical and dimensional
requirements of IEEE Standard 386.
The connectors can be used on any
comparably rated bushing interface
that also meets the requirements of this
standard. In addition, all cable adapters,

Deadbreak junctions are used in
pad-mounted apparatus, underground
vaults, and other installations to
establish loops, taps and splices, and
facilitate apparatus change-outs.
Sectionalizing a cable run to find and
isolate a cable fault is made easy
when a deadbreak junction is used
with deadbreak connectors meeting
the requirements of IEEE Standard
386™ – “Separable Insulated
Connector Systems”.
When mated with a comparably rated
product, the junction provides a fully
shielded, submersible threaded connection for deadbreak operation.
The deadbreak junction is available
with stainless steel adjustable brackets for mounting at various operating
angles, or with stainless steel “U”
straps for direct wall mounting.
900 AMP RATING
Copper deadbreak junctions are rated
900 A continuous. If a 900 A rating is
desired, select a copper deadbreak
junction from Table 4 on page 2.
INSTALLATION
Deadbreak junctions are bolted to the
mounting surface. 600 A connectors
are assembled onto junctions using
tools as described in the appropriate
installation instructions for those
connectors. Refer to Installation

600 A 25 kV Class
BT-TAP™ Deadbreak Connector
GENERAL
INTERCHANGEABILITY
The Cooper Power Systems 600 A,
25 kV Class BT-TAP™ Deadbreak
Connector is used to terminate
high-voltage underground cable to
transformers, switches, switchgear
and other apparatus. It is designed
for use with unthreaded compression
connectors, to easily retrofit existing
600 A Bol-T™ installations or in new
installations where a 200 A interface is
required and where the system will
not need to be frequently operated. If
the system will be frequently operated
to sectionalize or to achieve a visible
break or ground, Cooper recommends
the use of the T-OP™ II Connector
System. (See catalog section 600-32.)
The BT-TAP Deadbreak Connector is
fully shielded, submersible and meets
the requirements of IEEE Standard
386™ — “Separable Insulated
Connector Systems”.
The 200 A, three-phase rated loadbreak
interface provides a means for obtaining
a direct conductor test, visible ground
and provides a convenient location
for a Cooper M.O.V.E.™ Arrester or
grounding elbow.
Cooper Power Systems offers an
optional capacitive test point similar
to test points on our 200 A elbow
connectors. This allows use of
Cooper’s Type “TPR” Series Fault
Indicators, and provides a hotstick
operable means of determining
circuit condition when used with high
impedance voltage sensing devices
designed for test points.
BT-TAP Connectors are designed for
use on solid dielectric cable (XLPE or
EPR) with extruded semi-conductive
shields and concentric neutral, with or
without a jacket.
Installation on jacketed concentric neutral
cable may require additional sealing
material. Cold shrinkable adapters are
available for tape shield, linear corrugated,
unishield, and drain wire cables for use
with deadbreak connectors.
All Cooper Power Systems 600 A
Deadbreak Connectors conform to the
electrical, mechanical and dimensional
requirements of IEEE Standard 386™.
The connectors can be used on any
comparably rated bushing interface
that also meets the requirements of
this standard. In addition, all T-bodies,
cable adapters, insulating plugs and
compression connectors are designed
to be interchangeable with those
currently available from other major
manufacturers that also certify their
components to IEEE Standard 386™.
INSTALLATION
The T-body is assembled onto prepared
cable with an unthreaded compression
connector. The short end of a special
copper alloy stud, provided with the
kit, is torqued onto a de-energized
600 A bushing. Using a T-WRENCH,
the loadbreak reducing tap plug is
threaded onto the stud drawing the
entire assembly tight to the apparatus
bushing. The assembly is then torqued
to the apparatus bushing using a
torque wrench. Refer to Installation
Instruction Sheet S600-15-3 for details.

Electrical Apparatus
600 A 15 and 25 kV Class
U-OP™ Visible Break Connector System
600-34
GENERAL
The RTE® 600 A, 15 and 25 kV
Class U-OP™ Visible Break Connector System is used to provide a
visible break and the capability for
visible ground at transformers,
switches, switchgear and other
apparatus while performing repair
work on underground cable or while
used as a splice. The U-OP system
achieves a visible break and visible
ground without having to move
heavy 600 A cable. It is fully
shielded, submersible, and meets
the requirements of ANSI/IEEE
Standard 386 – Separable Insulated Connector Systems.
Many configurations are possible
with the U-OP connector system.
Under normal operating conditions
with a deadfront switchgear application, the current path through the
U-OP is through the apparatus
bushing, through the U connector,
through a two-way 600 A deadbreak
junction, and through a T-OP™ II
600 A connector (sold separately) to
the underground cable (see Figure 2).
The U connector creates a current
path from the apparatus bushing to
one bushing of the deadbreak junction. The U connector consists of
EPDM rubber molded around an
aluminum (copper optional) casting
(see Figure 3). Between the two
legs of the U connector is a shaft,
which threads onto a mating stud
attached to the apparatus by rotating the U connector's handle with a
shotgun stick. This threaded connection secures the U connector to
the apparatus and provides a
mechanical advantage in both mating and separating the rubber
interfaces.
When isolating underground cable,
the U connector (while de-energized) can be removed from the
deadbreak junction and apparatus
bushing (using a hotstick), rotated,
and placed with one leg back on the

apparatus bushing and the other
leg on a grounded standoff bushing
mounted in the parking stand. This
provides a visible break and ground
for the apparatus. (If a utility's practices do not require grounding the
apparatus, an insulated standoff
bushing may be installed in the
parking stand instead.) A 200 A
grounding elbow can be placed on
the 200 A interface of the T-OP II
connector, providing a visible
ground and allowing for safe repair
of the underground cable. A U-OP
600 A protective cap can be placed
on the exposed bushing of the
deadbreak junction, resulting in all
bushings being grounded or covered
with an insulated protective cap.
The U-OP connector system is
available with a three-way 600 A
deadbreak junction as well as a
two-way 600 A junction. Using a
three-way junction allows flexibility
in splicing applications or provides
an available bushing to which a
SCADA system can be connected.
Because the U connector is
installed on the equipment even
while performing repair to the
underground cable, its interfaces
are not exposed to the environment. This reduces the possibility
of contamination to the U
connector's interfaces.

The 200 A three-phase rated
loadbreak interface on the T-OP II
connector provides a means for
obtaining a live test as well as a

INSTALLATION
One leg of the U connector is 3 inches
longer to allow the U-OP connector
system to be used with different
types of bushings. For example,
welded bushings stick out a different
height off the apparatus' frontplate
than clamped bushings do. During
installation, the deadbreak junction
and the parking stand, which are
mounted on studs welded to the
frontplate, need to be adjusted to the
correct distance off the frontplate to
allow the U connector to be properly
installed. Alignment gauges available
from Cooper Power Systems are
recommended to assist in installing
the deadbreak junction and parking
stand correctly.
The U-OP connector system can be
retrofitted to many apparatus. There
are two options for installing the
deadbreak junction and parking
stand onto studs. One option is to
weld studs to the frontplate. The
other option is to purchase a retrofit
plate that already has studs welded
to it in the proper positions. Please
contact your Cooper Power Systems
representative for more information
on retrofitting the U-OP connector
to your apparatus.

600 A 25 kV Class
PUSH-OP ® Deadbreak Connector
600-33
GENERAL
The Cooper Power Systems 600 A,
25 kV Class PUSH-OP® Deadbreak
Connector offers a complete threadless deadbreak, hotstick operable
connection system for terminating
underground cables to transformers,
switches, switchgear, and other apparatus. It is fully shielded, submersible,
and meets the requirements of IEEE
Standard 386™ – Separable
Insulated Connector Systems.
The design employs a unique, 600 A
rated, plated copper probe and
mating PUSH-OP Bushing utilizing a
plated copper finger contact system.
PUSH-OP's stainless steel latching,
linkage mechanism provides leverage
for easy disconnection of the
terminator and easy handling of heavy
cable. The result is a one-person, hotstick operable connection system that
is unequalled in ease of operation and
time required to perform sectionalizing
operations.
A coppertop compression connector is
provided for terminating the conductor.
The 200 A three-phase rated loadbreak
interface provides a means for obtaining a live test, visible ground and visible break using a hotstick. It also provides a convenient location for a
Cooper M.O.V.E.™ Arrester or
Grounding Elbow. The grounding
elbow may be continuously connected
to the PUSH-OP while moving it to and
from an apparatus bushing.
Cooper Power Systems offers an
optional capacitive test point similar to
test points on 200 A elbow
connectors. This allows use of Type
S.T.A.R.™ (TPR) Series Fault
Indicators.
The PUSH-OP also has a non-bolted
connection that eliminates threading
and its associated problems.

deadbreak connectors.
INSTALLATION
The T-body housing with stainless
steel shroud is assembled onto
prepared cable with a threaded
coppertop spade lug compression
connector. The loadbreak reducing
tap plug is threaded into the connector
and onto a probe using an alignment
tool, installation torque tool, and
T-wrench.
The assembled housing is then
connected to a de-energized 600 A
PUSH-OP type bushing interface and
bracket using hotline equipment
without any threading operation.

600 A 15/25 kV Class
Bol-T™ Deadbreak Connector
GENERAL
The Cooper Power Systems 600 A,
15/25 kV Class Bol-T™ Deadbreak
Connector is used to terminate highvoltage underground cable on
deadfront apparatus such as transformers, switches and switchgear. It is fully
shielded, submersible and meets the
requirements of IEEE Standard 386™
– “Separable Insulated Connector
Systems”.
The capacitive test point on the
insulating plug provides a means of
testing the circuit without disturbing
the bolted connection.
In addition to the capacitive test point
feature on the insulating plug, Cooper
Power Systems offers an optional
capacitive test point similar to the test
points on Cooper 200 A Elbows. This
allows the use of the Type “TPR”
Series Fault Indicators, and provides a
hotstick operable means of determining
circuit condition when used with high
impedance voltage sensing devices
designed for test points.
Bol-T Connectors are designed for
use on solid dielectric cable (XLPE or
EPR) with extruded semi-conductive
shields and concentric neutral, with or
without a jacket.
Installation on jacketed concentric
neutral cable may require additional
sealing material. Cold shrinkable
adapters are available for tape shield,
linear corrugated and drain wire cable
adaptation for use with deadbreak
connectors.
900 AMP RATING
The Bol-T is rated for 900 A continuous
when used with a coppertop compression connector, copper insulating
plug, copper stud and copper bushing
or junction. If a 900 A rating is desired,
specify a “C” as the 9th digit when
determining your part number.
See Step 3, page 4.
INTERCHANGEABILITY
All Cooper Power Systems 600 A
Deadbreak Connectors conform to the
electrical, mechanical and dimensional
requirements of IEEE Standard
386™. The connectors can be used
on any comparably rated bushing interface that also meets the requirements

BT-TAP™ Deadbreak Connector
600-15
GENERAL
INTERCHANGEABILITY
The Cooper Power Systems 600 A,
15 kV Class BT-TAP™ Deadbreak
Connector is used to terminate
high-voltage underground cable to
transformers, switches, switchgear
and other apparatus. It is designed
for use with unthreaded compression
connectors, to easily retrofit existing
600 A Bol-T™ installations or in new
installations where a 200 A interface is
required and where the system will not
need to be frequently operated. If the
system will be frequently operated to
sectionalize or to achieve a visable
break or ground, Cooper recommends
the use of the T-OP™ II Connector
System. (See catalog section 600-12.)
The BT-TAP Deadbreak Connector is
fully shielded, submersible and meets
the requirements of IEEE Standard
386™ –– “Separable Insulated
Connector Systems”.
The 200 A, three-phase rated loadbreak
interface provides a means for obtaining
a direct conductor test, visible ground
and provides a convenient location
for a Cooper M.O.V.E.™ Arrester or
grounding elbow.
Cooper Power Systems offers an
optional capacitive test point similar
to test points on our 200 A elbow
connectors. This allows use of Cooper’s
Type “TPR” Series Fault Indicators, and
provides a hotstick operable means of
determining circuit condition when used
with high impedance voltage sensing
devices designed for test points.
BT-TAP connectors are designed for
use on solid dielectric cable (XLPE or
EPR) with extruded semi-conductive
shields and concentric neutral, with or
without a jacket.
Installation on jacketed concentric
neutral cable may require additional
sealing material. Cold shrinkable
adapters are available for tape shield,
linear corrugated, unishield, and drain
wire cables for use with deadbreak
connectors.
All Cooper Power Systems 600 A
Deadbreak Connectors conform to the
electrical, mechanical and dimensional
requirements of IEEE Standard 386™.
The connectors can be used on any
comparably rated bushing interface
that also meets the requirements of
this standard. In addition, all T-bodies,
cable adapters, insulating plugs and
compression connectors are designed
to be interchangeable with those
currently available from other major
manufacturers that also certify their
components to IEEE Standard 386™.
INSTALLATION
The T-body is assembled onto prepared
cable with an unthreaded compression
connector. The short end of a special
copper alloy stud, provided with the
kit, is torqued onto a de-energized
600 A bushing. Using a T-WRENCH,
the loadbreak reducing tap plug is
threaded onto the stud drawing the
entire assembly tight to the apparatus
bushing. The assembly is then torqued
to the apparatus bushing using a
torque wrench. Refer to Installation
Instruction Sheet S600-15-3 for
details.

600 A 15 kV Class
PUSH-OP ® Deadbreak Connector
600-13
GENERAL
The Cooper Power Systems 600 A,
15 kV Class PUSH-OP® Deadbreak
Connector offers a complete threadless deadbreak, hotstick operable
connection system for terminating
underground cables to transformers,
switches, switchgear, and other apparatus. It is fully shielded, submersible,
and meets the requirements of IEEE
Standard 386™ – Separable
Insulated Connector Systems.
The design employs a unique, 600 A
rated, plated copper probe and
mating PUSH-OP Bushing utilizing a
plated copper finger contact system.
PUSH-OP's stainless steel latching,
linkage mechanism provides leverage
for easy disconnection of the
terminator and easy handling of
heavy cable. The result is a one-man,
hotstick operable connection system
that is unequalled in ease of operation
and time required to perform
sectionalizing operations.
A coppertop compression connector
is provided for terminating the
conductor.
The 200 A three-phase rated loadbreak
interface provides a means for obtaining
a live test, visible ground and visible
break using a hotstick. It also provides
a convenient location for a Cooper
M.O.V.E.™ Arrester or Grounding
Elbow. The grounding elbow may be
continously connected to the PUSH-OP
while moving it to and from an apparatus bushing.
Cooper Power Systems offers an
optional capacitive test point similar to
test points on 200 A elbow connectors.
This allows use of Type S.T.A.R.™
(TPR) Series Fault Indicators.
The PUSH-OP also has a non-bolted
connection that eliminates threading
and its associated problems.
PUSH-OP Connectors are designed
for use on solid dielectric cable (XLPE
or EPR) with extruded semi-conducting
shields and concentric neutral, with or
without jacket. Installation on jacketed
concentric neutral cable may require
additional sealing material. Cold
shrinkable adapters are available for

INSTALLATION
The T-body housing with stainless
steel shroud is assembled onto prepared cable with a coppertop threaded spade lug compression connector.
The loadbreak reducing tap plug is
threaded into the connector and onto
a probe using an alignment tool,
installation torque tool and T-wrench.
The assembled housing is then connected to a de-energized 600 A
PUSH-OP type bushing interface and
bracket using hotline equipment without any threading operation. (See

600 A 15 kV Class
T-OP™ II Deadbreak Connector
GENERAL
The Cooper Power Systems 600 A,
15 kV Class T-OP™ II Deadbreak
Connector is used to terminate highvoltage underground cable to
transformers, switches, switchgear
and other apparatus. It is fully shielded,
submersible and meets the requirements of IEEE Standard 386™ –
“Separable Insulated Connector
Systems”.
The 200 A three-phase rated loadbreak interface provides a means for
obtaining a live test, visible ground and
visible break using a hotstick. It also
provides a convenient location for a
M.O.V.E.™ arrester or grounding
elbow.
Cooper Power Systems offers an
exclusive optional capacitive test point
similar to test points on 200 A elbow
connectors. This allows use of Type
“TPR” Series Fault Indicators.
T-OP II connectors are designed for
use on solid dielectric cable (XLPE or
EPR) with extruded semi-conducting
shields and concentric neutral, with or
without a jacket. Installation on jacketed concentric neutral cable may
require additional sealing material.
Adapters are available for terminating
tape shield and drain wire jacketed
cable (see sections 600-70 and
600-75).
INSTALLATION
The T-body is assembled onto
prepared cable with a threaded
coppertop compression connector
using the alignment segment and a
T-Wrench. The short end of a special
copper alloy stud, provided with the kit,
is torqued onto a de-energized 600 A
bushing. The assembled housing is
then connected to the apparatus
bushing using an O & T tool (with
cap) and an installation torque tool.
The T-OP ll’s unique back-off feature
is accomplished by a captured rotating
nut, which provides ease of removal of
the T-OP II system from the apparatus
bushing. (See Table 4 for information
on tools.) Refer to Installation
Instruction Sheet 5000050708 for
details.

ORDERING INFORMATION
Cable Adapter
To order cable adapters, refer to
Table 5. These cable adapters are for
use on the Bol-T™, T-OP™ II, and
PUSH-OP® connection systems.
Determine the cable diameter over
the high-voltage insulation and
specify the catalog number using
Table 5. Insulation diameter must fall
within the range of the appropriate
cable adapter as cable diameter can
vary ± 0.030".
Example: To order a cable adapter of
1.200 inches, determine the cable
diameter range as follows:
1.200 - 0.030 = 1.170 minimum
diameter
1.200 +0.030 = 1.230 maximum
diameter
Therefore, specify CA635J.
CABLE ADAPTER
Molded cable adapter is available in
sizes to fit cables from 0.875" to 1.965"
in diameter (22.2 to 49.9 mm).
Molded of high quality peroxide cured
insulation and semiconductive rubber
to provide stress relief for terminated
cable. Refer to Table 5.

EXAMPLE: Select a Bol-T Kit for 250 kcmil compressed cable with a nominal insulation diameter of 1.160" ± 0.030".
The kit should have aluminum current-carrying parts and should have a stud included. The T- Body should have a test
point.
Step 1 – Select Digit 6
Nominal diameter over insulation is 1.160" ± 0.030".
Minimum diameter = 1.160" - 0.030" = 1.130".
Maximum diameter = 1.160" + 0.030" = 1.190".
From Table 3, identify the cable range that covers 1.130" - 1.190" and select the “F” cable range code.
Step 2 – Select Digits 7 and 8
The conductor size is 250 kcmil compressed. From Table 4, under the column “Concentric or Compressed,” identify
250 kcmil and select the “17” conductor code.
Step 3 – Select Digit 9
The kit should have aluminum current-carrying parts. Select an “A” for digit 9.
Step 4 – Select Digit 10
The kit should include a stud, so select 1 for digit 10.
Step 5 – Select Digit 11
A test point is needed, so use a “T” for digit 11.
