10KV 11KV 12KV 24KV 33KV outdoor HV High Voltage VCB automatic recloser
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.
