Power Substation Circuit Breaker ZN85A-40.5KV High Voltage Vacuum Circuit Breaker
Power substation ZN85A-40.5KV high voltage vacuum circuit breaker
Quick Detail:
Power substation ZN85A-40.5KV high voltage vacuum circuit breaker(VCB)
ZN85A-40.5KV vacuum circuit breaker is a type of high voltage switch
equipment which appropriate to 12kv, 50Hz three phase alternating current system, applicable for protecting and controlling,
especially appropriate to frequent operation and short circuit places. This type is mainly used in fixed type switchgear, it can not
only use alone, but also in loop network, box-type and other kinds of nonstandard power supply system.
