Technology
What is solid dielectric insulation?
G&W’s solid dielectric insulation is a field proven epoxy
which is used to insulate the high voltage connections of
a vacuum switch. The load break and fault interrupting
vacuum bottle and bushing conductors are fully over molded creating a single phase module. Each module is then
coated with a semi-conductive paint creating a continuous
grounding surface for a truly dead front design. For three
phase switches, three modules are combined together to
create one way of the switch.
Drive rod
Each module can also include an integral current transformer fully protected by the solid dielectric epoxy. This
ensures that the transformer is impervious to environmental conditions and insulated from extreme temperatures.
Encapsulated
current
transformer
G&W’s molding expertise allows for various options including 200A bushing wells or 600A apparatus bushings. The
rugged epoxy surface minimizes the force required for removing elbow connections compared to rubber-to-rubber
junctions. Different module orientations are available which
permit cable entry from the front, back, or bottom of the unit.
Vacuum bottle
The solid dielectric insulations and vacuum bottle combination make the Trident switchgear suitable for wet and
corrosive environments, vertical or horizontal mounting
and use in any altitude.
When
you need visible break ...
Trident
with
SafeVu™
Trident switches are
available with the
SafeVu™ option. These
switches include an
innovative
visible
break feature built
into the switch, which
eliminates the need to
remove elbows or use
externally
mounted
components
to
provide a visible open. p Close up of integrated visible The SafeVu operating
break in the open position
handle is operable via
hook stick or rope rigging, making it ideal for subsurface
applications where space or safety practices prevent the
operator from entering the vault to create a visible break.
Description
The visible break is achieved with a blade type switch
incorporated within the solid dielectric module. The blade
is in series with the vacuum interrupter and provides a clear
visible open. The blade is easily visible through a viewing
window molded as an integral part of each module.
p Internal components are shown outside the module as reference.

Multi-way Trident Solid Dielectric Switches
Trident solid dielectric insulated switches provide the total life
cycle cost and operational benefits of fuseless, electronically
controlled, resettable overcurrent protection, with the safety
and maintenance benefits of an environmentally friendly
dead-front design.
The Trident utilizes G&W’s time proven, submersible epoxy
insulation to fully encapsulate load and fault interrupting
vacuum interrupters. This solid dielectric insulation
eliminates the degradation of dielectric integrity commonly
associated with oil and air insulated switchgear.
VLS Switch Series
The Trident VLS Series is available in two through six way
configurations, in any combination of three phase load
break switch ways and three phase fault interrupter ways.
The fault interrupter utilizes a trip-free mechanism, which
provides interruption independent of the operating handle
when closing into a fault. Viewing windows provide visible
indication of the contact position.
VLT Switch Series
The Trident VLT Series is available in two through six way
configurations, in any combination of three phase load
break switch ways and single phase fault interrupter ways.
Each fault interrupting mechanism incorporates a tripfree design which permits interruption independent of the
operating handle if closing into a fault. Each phase of the
fault interrupting mechanism can be independently tripped
and reset, providing the ability to maintain energization of
the other phases in the case of a single phase fault. Viewing
windows permit visible indication of the contact position of
all phases.
Applications
Trident load and fault interrupting combination switches
provide a direct replacement for power fused and vacuumin-oil switchgear. Some ideal applications include:
Transformer and Motor Protection — The three phase
trip feature and high continuous current make the VLS
switches ideal for protecting three phase motors and transformer loads.
Loop Switching — Standard 600A loop switching is
accomplished using field proven vacuum switching and
solid dielectric insulation. Switching through 630A provides
up to 12.5kA symmetric fault protection using resettable,
electronically controlled vacuum interrupters. The vacuum
interrupters also function as load break switches.
Residential and Fuse Replacement — The single phase
trip feature of the VLT switches makes them ideal for protecting single phase motors and transformer loads.

Additional Features
Visible Break — The load break and three phase fault
interrupter ways are available with G&W’s SafeVu feature,
which provides an integrated visible break disconnect
switch in series with the vacuum interrupter. This eliminates
the need to remove elbows or use externally mounted linkage systems to provide a visible open. Switches equipped
with the SafeVu feature incorporate redundant mechanical
interlocks to ensure the load break switch is open prior to
the operation of the visible break switch.
Testing
Trident switches are designed and tested to applicable standards including IEEE C37.74 (IEEE C37.71 and C37.72),
IEEE 386, IEC 60265, IEEE 592,. All fault interrupter devices have passed IEEE C37.60. Trident switches are RUS
accepted.
Fully encapsulated current transformers provide power and
sensing for G&W’s Vacuum Interrupter controls. The controls emulate the most common time current curves (TCC)
for power fuses, mechanical relays, and fuse links. Control
options include Ground Fault (Phase Imbalance), Time Delays, and Inrush Restraint (Cold Load Pickup).
Submersibility
G&W VLS and VLT solid dielectric switchgear is completely
submersible. Units have remained fully operable after
withstanding years of submersion at depths of up to 10
feet (3m).

Two-way Trident Solid Dielectric Switches
Trident solid dielectric insulated switches provide the total life
cycle cost and operational benefits of fuseless, electronically
controlled, resettable overcurrent protection, with the safety
and maintenance benefits of an environmentally friendly
dead-front design.
The Trident utilizes G&W’s time proven, submersible epoxy
insulation to fully encapsulate load and fault interrupting
vacuum interrupters. This solid dielectric insulation
eliminates the degradation of dielectric integrity commonly
associated with oil and air insulated switchgear.
Configurations
The two way Trident is available as a loadbreak switch or
a fault interrupter. The fault interrupter utilizes a trip-free
mechanism, which provides interruption independent of the
operating handle when closing into a fault. Viewing windows
provide visible indication of the contact position.
Applications
Trident load and fault interrupting switches provide a direct
replacement for vacuum-in-oil switchgear. Some ideal
applications include:
Transformer and Motor Protection — The three phase
trip feature and high continuous current make the two way
Trident fault interrupters switches ideal for protecting three
phase motors and transformer loads.
Oil Fuse Cutout Replacement — Eliminate the need to
replace fuse links or maintain insulating oil. The Trident with
SafeVu does not require any maintenance and features
compact size, lightweight, integral visible break, and fault
interrupting capability. It is the perfect solution to replace
obsolete oil fuse cutouts.
Additional Features
Visible Break — The Front Access two way Trident is
available with G&W’s SafeVu feature, which provides an
integrated visible break disconnect switch in series with
the vacuum interrupter. This eliminates the need to remove
elbows or use externally mounted linkage systems to provide a visible open. Switches equipped with the SafeVu
G&W ELECTRIC
PA G E 1 2
p Front Access Design
feature incorporate redundant mechanical interlocks to
ensure the load break switch is open prior to the operation
of the visible break switch.
Testing

Components for Three Phase Switches
Overcurrent Protection
Fault interrupters are equipped with an encapsulated
500:1 or 1000:1 current transformer and a G&W self
powered Vacuum Interrupter Control. Alternately, a wide
variety of protective relay packages are available, including relays from SEL and other leading relay suppliers.
Motor Actuator
Automation begins with the addition of motor actuators to
a manual switch. These actuators can be factory installed
for new equipment or retrofitted to switchgear installed in
the field. (Refer to the Motor Operator catalog, MO11, for
motor control options.)
External CTs
and External PTs
Metering or relaying accuracy current and potential
transformers are available for use with protective relay
packages.
Operating Handle
G&W will select the appropriate handle based on the
application. Handles are operable via hook stick or rope
rigging.
Key Interlocks
Key interlocks may be
used to ensure safe
coordination of equipment. All Trident ways
can be equipped
with provisions for
key interlocks. Key
interlocks can be provided, and factory
installed if required.
p Key interlock
Auxiliary Contacts
Auxiliary contacts are mounted internal to the mechanism
housing to provide remote indication of switch contact
position. One normally open and one normally closed
Form C contact is provided. A junction box is available
with terminal strip connections for up to four auxiliary
contacts.

Single Phase
Trident solid dielectric insulated switches provide
the total life cycle cost and operational benefits of
fuseless, electronically controlled, resettable overcurrent
protection, with the safety and maintenance benefits of
an environmentally friendly dead-front design.
The Trident utilizes G&W’s time proven, submersible
epoxy insulation to fully encapsulate load and fault
interrupting vacuum interrupters. This solid dielectric
insulation eliminates the degradation of dielectric integrity
commonly associated with oil insulated switchgear.
Single Phase
Trident single phase, spring-assisted switchgear is available for load break or fault interrupting switching. The
compact units are ideal for switching residential loops
and for oil fuse cutout replacements. Fault protection can
be provided using a vacuum interrupter with an integral
current transformer and a variety of overcurrent controls.
The Single Phase Trident is available in a Front Access
design, with operating handles and bushings on the
same side of the switch. The switch can be mounted
in any orientation to best meet the requirements of the
application.
Additional Features
Visible Break — The single phase Trident is available
with G&W’s SafeVu feature at 15kV, which provides
an integrated visible break disconnect switch in series
with the vacuum interrupter. This eliminates the need to
remove elbows or use externally mounted linkage systems to provide a visible open. Switches equipped with
the SafeVu feature incorporate redundant mechanical
interlocks to ensure the load break switch is open prior
to the operation of the visible break switch.
p Single phase Trident switch
Testing
Trident switches are designed and tested to applicable
standards including IEEE C37.74 (IEEE C37.71 and
C37.72), IEEE 386, IEC 60265, and IEEE 592. All fault
interrupter devices have passed IEEE C37.60. Trident
