Product overview
ZW32-11KV-24KV outdoor AC high-voltage vacuum circuit breaker (hereinafter referred to as the circuit breaker) is an outdoor power distribution equipment with a rated voltage of 11-24KV, 50Hz three-phase AC. It is mainly used for breaking and closing the load current, overload current, and short-circuit current in the power system of the distribution network. It is suitable for protection and control in the power distribution systems of substations and industrial and mining enterprises, and it is more suitable for rural power grids and places with frequent operations.
Using environmental conditions:
