Applications
Power stations generate electrical power, with voltages up
to 500,000V, which is transmitted to transformer stations
and dispersion stations. These substations distribute
medium voltage above 1kV to 36kV and it is here that
a number of NHP Medium Voltage Switchgear cubicles
can be used. A medium-voltage grid starts from every
substation and supplies a large area with medium-voltage.
Wherever medium-voltage enters residential areas,
industrial production companies, mining sites, data
centres, rail, hospitals and more, there is a medium voltage
cubicle fulfilling four essential functions.
1. POWER SUPPLY: the network distributor’s grid is
branched off to allow switching
2. SECURITY: the installation is secured with a load break
switch with HRC fuses, or by a load break switch with a
safety relay
3. MEASUREMENT: the energy consumption is measured
on the high-voltage, or low-voltage side
4. TRANSFORMATION: medium-voltage is transformed
into low-voltage (1,000V-400V-230V)

NHP Medium Voltage Switchgear OVERVIEW
DESIGN PHILOSOPHY AND APPLICATIONS
User-friendliness, safety and care for the environment
were the main motivators in the selection of NHP Medium
Voltage Switchgear. NHP can provide “made-to-measure”
solutions for all your medium-voltage needs.
NHP Medium Voltage Switchgear offers a wide range
of applications that can be used worldwide in many
industries. Cubicles can be used with distribution and
dispersion switchgear, electrical sub-stations and
medium-voltage engines, wind generators, cogeneration,
and much more.
The NHP Medium Voltage Switchgear range provides a
solution for all your needs and demands as it can replace
obsolete installations, extend existing installations, and it is
also perfectly suited for brand new installations.
The NHP Medium Voltage Switchgear cubicles are a
modular concept based on the “building blocks” principle,
which means that cubicles are produced in series. As a
result these products meet the highest technical standards
in a rational and economically sound way. The combination
of cubicles is unlimited. Very complex diagrams of
distribution and transformer switchgear can be compiled
through this extensive spectrum of possibilities.
Cubicles contain standard functional interlocks which
allows for effortless application and installation in most
consumer work spaces. As a result, capacity loss will be
minimal. Additionally, the cubicles have been fitted with
a system for pressure release which shields the user from
the consequences of an internal arc.
7
INTERNAL ARC MITIGATION
OPTION WITH BUILT-IN ARC-KILLER
A short-circuit or another malfunction can create an
internal arc. An internal arc in a Medium Voltage cubicle
could severely damage the installation and possibly injure
the operator.
Protect your cubicles, infrastructure and your staff against
the consequences of an internal arc. The built-in Arc-Killer
extinguishes an arc in less than 50ms.
NHP Medium Voltage Switchgear cubicles are designed to
mitigate the creation of internal arcs and therefore protect
both the operator and the installation. Through a strategic
pressure release system, the internal arc is restricted to
the compartment where it originated and it does not
spread towards the operator or to other compartments.
The cubicles are specifically designed to minimize the
consequences of an internal arc. All provided cubicles are
fitted on the rear side with overpressure valves pointing
downward as a standard.
NHP Medium Voltage Switchgear cubicles have been
tested with these specifications at independent, and
accredited testing solutions (for example: IPH, Kema).
The load break switches have been tested according to
IEC standards and consequently, all NHP Medium Voltage
cubicles are internal arc resistant.
Without Arc-Killer
The NHP Medium Voltage Switchgear range includes the
Arc-Killer SV-25 and SV-53, a system for detecting and
extinguishing an internal arc. The Arc-Killer extinguishes
the arc by directing it to a metal earthed short circuit. The
arc is extinguished in less than 50ms.
Our modules are metal enclosed cubicles combined
with a shaft at the rear end. The shaft absorbs any gasses
(in case of an internal arc) that escape through the
overpressure valves. As a result, the expansion of hot
gasses in a room can be reduced to an absolute minimum.
NHP Medium Voltage Switchgear cubicles offer protection
against an internal arc classification IAC category B, FLR 20
kA 1 s. (F=frontal, L=lateral, R=rear).
As a result, the operator is protected against the
consequences of an arc whether they stand in front of the
switchboard, next to it or behind it.
With Arc-Killer
The patented SV-25 and SV-53 Arc-Killer takes safety to a new level. Not just the operator and the environment are
shielded from harm, but the super-swift arc extinguishing system allows cubicles to be back in operation very quickly
in case of an internal fault.
What’s more, the Arc-Killer’s improved security features place less strict demands on the installation room.
As such, the Arc-Killer couples security and operational safety with flexible room demands.

COMPARTMENTS
SWITCHGEAR COMPARTMENT
In this compartment, the gas filled (RV44) load break switch is
double sealed, which acts as the physical separation between
the busbar set and the cable compartment. The switch has
two functions: it connects or interrupts the electrical current
between the high voltage cables and the busbar.
BUSBAR COMPARTMENT
The busbar compartment is located in the upper part of
the cubicle and behind the low-voltage compartment. The
modular busbar set is manufactured from specially provided
electrolyte F25 copper of 60 x 10mm with n = 5mm (800A).
Standard as well as 1250A option is available.
Several cubicles are connected through the bar set
compartments. Hexagonal bolts connect the busbars to the
upper contact surfaces of the RV44 load break switch.
CABLE COMPARTMENT
The cable compartment is located behind the interlocked,
removable door of the DF-2 cubicle. This part of the field
receives the cable(s) and contains the necessary equipment
to connect the cable(s). The earthing switch is installed below
the load break switch on the right side, ensuring a “visible
earthing” when the earthing switch is closed. In a DF-A cubicle,
the cables are connected to the contact points below the
RV 44 load break switch. The cables of the DF-P cubicles are
connected to the lower fuse base side. This type of cubicle
also has an additional auxiliary earthing switch to divert any
residual current. DF-D type cubicle have the earthing switches
located in the cable compartment below. The removable
door, the sectional floor panels which house the necessary
conductive rubber for the cables, and the cable supports all
simplify the cable connection.
LOW-VOLTAGE COMPARTMENT

LOW-VOLTAGE COMPARTMENT
The drive mechanism that controls the RV44 load break switch
and the earthing switch EM20 is fitted with the synoptic
diagram and is located behind the front panel. Several
accessories, such as the auxiliary contacts, switch-on or
switch-off coils, and minimum voltage relays are also located
in this compartment. Any control with the necessary electrical
switchgear, a control and clamp strip are also installed in
this compartment. The compartment is easily accessible by
removing the front panel.

DR-6/DT-6
DEVELOPMENT & MANUFACTURING PHILOSOPHY
The DR-6/DT-6 range offers a compact, safe, reliable and economical design which is free of any possible environmental
aggression. Extensions on site is possible without any special tooling nor particular surrounding conditions.
THE COMPONENTS
Load break switch
The three position load break switch (ON/OFF/Earth) is in accordance with the IEC
requirements. The concept insures a natural interlock of the primary functions of the cubicle.
The arc extinction is insured by gas, which reduces arcing time. The load break switch RV44 of
the DF-2 range is of the class E3/M1 (100 CO and 1000 mechanical operations) following IEC
62271-103 and is therefore a perfect application.
Circuit breaker
The SGC ISM-086 vacuum circuit breaker (VCB) of the magnetic actuator type uses the
latest vacuum interrupter technology. The VCB can only be closed electrically and therefore
mechanical closing is not possible*. The VCB can be opened only electrically. The circuit breaker
operates through a control module and a self powered digital protection relay RP600, this
together with the three CT’s allows the detection of over-current and earth faults failures.
(*) In absence of auxiliary voltage, a hand operated generator can be used.
The fuse holders
The fuse holders are made for HRC fuses of the DIN and UTE type for voltages of 12, 12 (Utilities
Specification) and 24kV. A simple intelligent artifice allows the change without any particular
tooling. Fuse holders are made from epoxy with a non-losable cover, and a fuse supporting
structure firmly fixed to the cover. Earthing on both sides of the fuses is clearly marked on
the synoptic diagram. The fuse holder is water tight and tested in accordance with the IEC
standards. Access to the fuse holders is facilitated by a simple and logic interlock system
allowing the opening of the door only after earthing of the cubicle.
The mechanical drives
Deba Components mechanical drives have already been subject to intensive tests and usage
in the DF-2 range of products. The same design has been implemented in the DR-6/DT-6. The
steel used for the drives has been chosen because of their high tensile force, toughness and
resistance to bending. The mechanical drive accommodates both the operates axles (LBS and
earth) and the interlocks. The spring type drive operates independently of the operator and
does not allow any function violation. The switch position indicator shows at any time the
real status of the switch. The forces needed to control the mechanism are low which results
in a high user-friendliness. The drive can be motorized and can receive a number of options
and allows remote control, remote position indication and integration into a SCADA operated
network.
30
DR-6/DT-6
Cable connection
The cables are connected to the cubicles by means of bushings with M16 screwed contacts
and for connectors according to EN 50 181 / DIN 50 standards. They may be of the type A/B or
C (200, 400 630A) and they are defined in function of their applications.
The cable compartment size allows one connector per bushing with a maximum of 400mm2
per cable (on request, lightning arrestors can also be accommodated in the cable box as well as
two cables per bushing).
The extensibility concept
Extensibility of the ring main unit is ensured by top placed bushings of the C- type.
An insulated and screened extension device connects the two sets to be extended. Extension
requires no special tooling nor special on site condition.
The bushings are directly moulded on a stainless steel plate avoiding any risk of leakage caused
by mechanical assembly.
The synoptic diagram and the accessories
A clear, logic and well understandable synoptic diagram is placed in front of each of the
functions. This diagram also supports the voltage indicator of the type HR-3, showing the
presence of the voltage on the cables and allowing the use of phase concordance units.
Short circuit indicators can find their place in the LV compartment and the associated ring type
CT’s in the cable box. Complementary accessories can be accommodated in a well designed LV
box to be placed on the top of the concerned function(s).

DW-2
WITHDRAWABLE SWITCHGEAR
DW-2
A family of air-insulated fully withdrawable medium
voltage switchgear solutions for indoor installations.
DW-2’s modular design allows you to create rational,
economical and custom-made combinations of medium
voltage cubicles (up to 12kV).
34
DW-2
Type tests
DW-2 switchgear solutions are all fully type tested according
to IEC 62271-200:
•
•
•
•
•
•
•
Short time and peak withstand current
Temperature rise and main circuit impedance
Dielectric test on main and auxiliary circuits
Making and breaking capacity of the circuit breaker within
the panel
Earthing switch making capacity
Mechanical operations
Internal arc fault (IAC classified: AFLR, 31.5A/1s)
Availability and partition
DW-2 switchgears are designed in compliance to availability
classes LSC2B and partition class PM according to
IEC 62271-200.
The switchgear compartments do not need any tools for
opening. Interlocks allow access only when the corresponding
high voltage parts are dead and earthed. Metallic shutters and
partitions segregate the compartments from each other. When
a compartment is opened all other panels in the installation
and all cable termination compartments (including that in the
panel concerned) remain in operation.

LOW-VOLTAGE COMPARTMENT
The protection relays that controls the circuit breaker and
accessories, such as the auxiliary contacts, and minimum
voltage relays, are also located in this compartment. The
compartment can be accessed very easily by opening the
compartment door.
LOW-VOLTAGE COMPARTMENT
BUSBAR COMPARTMENT
SWITCHGEAR COMPARTMENT
BUSBAR COMPARTMENT
The busbar compartment is located in the back side of the
cubicle and behind the low-voltage compartment. The
modular busbar set is manufactured from specially provided
electrolyte F25 copper. Several cubicles are connected
through the bar set compartments. Hexagonal bolts connect
the busbars to the upper contact surfaces of the fixed
contacts in the insulators.
CABLE COMPARTMENT
The cable compartment is located behind the interlocked,
removable door of the DW-2 cubicle. This part accepts the
cable(s) and contains the necessary equipment to connect
the cable(s). The earthing switch is installed below the circuit
breaker switch on the back side, ensuring a “visible earthing”
when the earthing switch is closed. The door and the sectional
floor panels, which house the necessary conductive rubber
for the cables, and the cable supports, all simplify the cable
connection.
CABLE COMPARTMENT
SWITCHGEAR COMPARTMENT
In this compartment, the withdrawable magnetic driven
vacuum circuit breaker switch, acts as the physical separation
between the busbar set and the cable compartment. The
switch has two functions: it connects or interrupts the electrical
current between the high voltage cables and the busbar.

LOW-VOLTAGE COMPARTMENT
The drive mechanism that controls the RV53 load break
switch and the integrated earthing switch is fitted with the
synoptic diagram and is located behind the front panel.
Several accessories such as the auxiliary contacts, switch-on or
switch-off coils, and minimum voltage relays, are also located
in this compartment. An optional motorized drive mechanism
with all the necessary control elements could also be installed
in this compartment. The compartment can be accessed very
easily by disassembling the front panel. Optional padlocks
prevent unauthorised access.
LOW-VOLTAGE COMPARTMENT
BUSBAR COMPARTMENT
SWITCHGEAR COMPARTMENT
BUSBAR COMPARTMENT
The busbar compartment is located in the upper part of
the cubicle and behind the low-voltage compartment. The
modular busbar set is manufactured from specially provided
electrolyte F25 copper Ø27mm (IrBB=630A). Various cubicles are
connected through busbar compartments. Hexagonal bolts
connect the busbars to the upper contact surfaces of the RV53
load break switch.
CABLE COMPARTMENT
The cable compartment is located behind the interlocked,
removable door of the DF-3 cubicle. This part of the cubicle
accommodates the cable(s) and contains the necessary
equipment to connect the cable(s). In a DF-A cubicle, the
cables are connected to the contact points below the
RV53 load break switch. The cables of the DF-P cubicles are
connected to the lower fuse base side. This type of cubicle
also has an additional auxiliary earthing switch to divert any
residual current. DF-D types have the earthing located in the
cable compartment below the circuit breaker. The removable
door, the sectional floor panels, which house the necessary
conductive rubber for the cables, and the cable supports, all
simplify the cable connection.
CABLE COMPARTMENT
SWITCHGEAR COMPARTMENT
In this compartment, the gas filled RV53 three position load
break switch acts as the physical separation between the busbar
set and the cable compartment. The switch has three functions:
it connects or interrupts the electrical current between the high
voltage cables and the busbar. Additionally, the earthing switch
is integrated.
