IEC 298 Single Busbar Panel
LMVP 12kV single busbar panel with withdrawable voltage transformer
The switchgear is housed in a Fixed Enclosure. This is a rigid sheet steel cubicle consisting of four main sections:
- Busbar and Current Transformer Chamber
The busbar chamber contains three-phase copper busbars rated at 1250A, 2000A, 2500A or 3000A.
The rear section of the chamber houses the current transformers which may be:
– Low voltage insulated, mounted on an earthed screened primary bushing, silica-filled epoxy resin insulated.
– Either bar or wound primary type depending on the specification.
– Current transformers comply with IEC 61869-1, IEC 61869-2.
The control cubicle houses the relays and control equipment, protection relays and instruments.
Air insulated cable boxes for heat shrink cable termination.
- Circuit Breaker Compartment
The bottom section houses the circuit breaker.
Guide rails allow smooth, safe and easy entry and removal of circuit breakers ensuring accurate location in the correct position.
