Product Description
ZW32-24 24kV Outdoor High Voltage Vacuum Circuit Breaker
ZW32-24 type outdoor H.V. vacuum circuit breaker (Hereinafter referred to as the circuit breaker) is outdoor distribution equipment with rated voltage 24KV, three phase AC 50Hz. It is mainly used for breaking and closing the load current, overload current and short circuit current of power system. Applied to substation and industrial and mining enterprises in power system for protection and control use, more suitable for rural power grid and the frequent operation place. The installation instructions provided content of circuit breaker references, the using condition, type and rated parameters, structure characteristics, working principle, order information, and operation, installation, use, maintenance principle and method etc..
