Equipped with VS1 vacuum circuit breaker with high breaking capacity and low cut-off value (also can be equipped with VD4 vacuum circuit breaker produced by ABB company) as the main switch, the structure is advanced, reasonable, compact, superior in performance, safe and reliable, and has ” Five defenses” interlocking function.
Current transformers, earthing switches, lightning arresters and cables can be installed in the cable room.
Accurate instruments monitor the operating status of the equipment in real time to ensure the safe and stable operation of the equipment.
The vacuum circuit breaker with mature technology can realize the stable operation of the equipment.
The advanced grounding switch used can be used in conjunction with various types of high-voltage switchgear.
The transformer is a fully enclosed type, and the winding is an epoxy resin full-vacuum casting full-insulation structure.
The protection performance of the arrester can determine the built-in insulation index of all electrical equipment in the power system.
