Outdoor vacuum circuit breaker ZW20-12

The ZW20-12 type outdoor high-voltage vacuum circuit breaker (hereinafter referred to as the circuit breaker) is an outdoor power distribution equipment with a rated voltage of 12kV and a three-phase AC 50Hz. It is mainly used to open and close the load current, overload current and short-circuit current in the power system. It is suitable for use in power transformation substations and industrial and mining enterprise power distribution systems as protection and control equipment. This circuit breaker has the characteristics of small size, light weight, dust-proof, maintenance-free, and can adapt to harsh climatic conditions and polluted environments, as well as frequent operation sites in rural power grids.
