1. 2017 Best quality of ZW8 series Outdoor vacuum circuit breaker VCB

XG company developed ZW8-12 outdoor vacuum circuit breaker some years ago, and it is widely used into dirstribution power projects in china.

ZW8-12 type outdoor high voltage vacuum circuit breaker is rated voltage of 12KV, 50Hz high voltage three-phase exchange of ideas outdoor switchgear, the main thing for breaking off Rural, urban network and small power system load current, overload current.

ZW8-12/630-20 series outdoor high voltage vacuum circuit breaker is main switch equipment of rated voltage 12KV,three phases AC 50HZ system,to switch on/off loading current,no-load current,and short circuit current,also used as the branch switch for rural power network or small power system,is a substitute for oil type breakers
