Summary
        ZW8-12 series outdoor high-voltage vacuum circuit breaker is an outdoor high-voltage switchgear with rated voltage of 12kV and three-phase alternating current of 50Hz, which is mainly used for switching off load current, overload current and short-circuit current of rural power grid, urban power grid and small power system. The overall structure of the product is three-phase common box type, the three-phase vacuum arc extinguishing chamber is placed in a metal box, and the SMC insulation material is used for inter phase insulation and ground insulation, with reliable performance and high insulation strength.
        Zw8-12g is composed of ZW8-12 circuit breaker and isolating knife. It is called combined circuit breaker. It can be used as section switch or self-contained power supply, with built-in Pt and external Pt.
The operating mechanism of this series of products is ct23 spring energy storage operating mechanism, which is divided into electric and manual.
