New type of LSC2B-PM (metal-clad) cubicle manufactured by Elko;
12-17.5-24-36kV voltage level, air insulated and metal enclosure.
Switchgear is mounted on a trolley.
Service continuity class is LSC 2B.
Sections are separated from each other by METAL partitions.
Access is possible from the FRONT, SIDE and BACK.
Suitable for internal (inside the building) use.
Type tests of the cubicles were conducted at KEMA.
There are different cubicles arrangements according to the functional feature of the cubicles.
(Example; Input/Output Cubicle with Breaker, Measurement Cubicle, Busbar Riser Cubicle, etc.)
NOTE: Vacuum or SF6 gas circuit breakers can be used in cubicles with breakers according to the BUYER’s request.
Advantages of use:
-High level of personnel and operational safety,
-High level of service continuity,
-Ease of operation and maintenance,
-Compatibility with new cell additions and regulations,
-Fast and safe switching equipment change thanks to switching equipment mounted on the car,
Main areas of application:
Electric energy production centers (power plants),
MV/HV and HV/MV transformer centers,
Distribution centers,
Organized industrial zones, pump stations,
Shopping centers
