METAL CLAD MV SWITCHGEARP4S PRODUCT RANGE
E+I Engineering’s Metal Clad MV switchgear range is an indoor air
insulated switchgear for medium voltage power distribution
P4 Series (P4S) is an indoor air insulated switchgear for medium
voltage power distribution. This new series of switchgear is based
around the ethos of safety and reliability and is a result of E+I
Engineering group’s quest for continuous innovation and long-term
R&D commitment.
The modular construction of the range allows E+I Engineering’s
team of expert engineers to customise each medium voltage power
solution based on individual project specification.
Key features:
– Circuit breaker is withdrawable for maintenance
– Integration of internal arc prevention technologies
– Vacuum Technology for safe, compact and reliable performance
– Compact and modular designfor increased project flexibility.
– Comprehensive mechanical and electrical interlocks for safety and
prevention of maloperation
Standards
The P4S range is type
tested and certified by an
NRTL. It is manufactured in a
certified management system
environment where Quality ISO
9001, Safety OHSAS 18001and
Environmental ISO 14001
standards are applied to all
aspects of the manufacturing
and installation processes. It is
manufactured in accordance
with ANSI C37.20.2
Type Tests
– Dielectric tests
– Power frequency withstand test
– Lightning impulse withstand test
– Measurement of the resistance
of the main circuits
– Temperature-rise tests
– Short-time withstand current
and peak withstand current tests
– Verification of the IP coding

MV SWITCHGEARMETAL CLAD P4S PRODUCT RANGE
SWITCHGEAR STRUCTURE
The panel is divided into 6 independent compartments which are
1. Cable Compartment
The cable compartment is accessible from the rear door. This door has
an interlock with the earth switch ensuring that the door will only open
when the earth switch is closed.
2. Potential transformer compartment
The potential transformer (PT) compartment allows for a withdrawable
PT to be connected and racked in. An interlock on the PT truck
ensures that the door must be closed before the PT is racked in.
3. Vacuum circuit breaker compartmentThe vacuum circuit breaker (VCB) compartment houses the
withdrawable VCB. An interlock on the VCB truck ensures that door
must be closed before the VCB can be racked in to the service
position.
4. Main busbar compartment
The main busbar compartment houses the main horizontal inter-
connecting bus. It is accessed via a removable panel at the rear of the
switchgear.
5. Plenum Assembly
If required the plenum assembly is bolted to the top of the enclosure,
the plenum assembly can be extended past the Switchgear to an
external wall.
6. Low voltage control compartment
The low voltage control compartment houses all the main control
and protection relays required. There is a direct connection from this
compartment to the wiring plug connected to the VCB.
SWITCHGEAR STRUCTURE
EnclosuresThe enclosure and partition are made from high quality cold rolled mild steel or galvanized sheet steel, the
processing of these materials is carried out by CNC punch and multiple edge folding technology. The panels
used within the structure are secured by means of riveting or high tensile nut and bolt.
– Side sheets are made from durable 11 gauge sheet steel incorporating advanced double bend technology
to ensure additional structural strength
– Gland plates made from 10 gauge stainless steel
– Exterior paint in RAL 7035 light grey
– Doors with integral strength enhancing struts
– Viewing window for visual confirmation of VCB status
