ZW32-12 12KV outdoor high voltage vacuum circuit breaker


Introduction


ZW32-24 series of outdoor vacuum circuit breaker (hereinafter referred to as circuit breaker) for rated voltage 24kV, three-phase AC 50Hz outdoor distribution equipment. Mainly used for load current, overload current and short-circuit current breaking, closing in electric power system. Applied to substation and industrial and mining enterprises distribution system for the protection and control of the rural power grid, and places with frequent operation.

This circuit breaker has the advantages of small volume, light weight, anti condensation, maintenance free, can adapt to the harsh climatic conditions and pollution environment.
