Main technical parameters of Xi'an ZW8-12 vacuum circuit breaker and 10KV circuit breaker

Xi'an - The main technical parameters of vacuum circuit breakers and circuit breakers are rated voltage and three-phase AC outdoor high-voltage switching equipment. They are mainly used to switch the load current, overload current and short-circuit current of rural power grids, urban power grids and small power systems. The overall structure of this product is a three-phase common box type. The three-phase vacuum arc extinguishing chamber is placed in a metal box. It uses insulating materials for inter-phase insulation and ground insulation. It has reliable performance and high insulation strength.
