Summary
        ZW32-12 outdoor column high voltage vacuum circuit breaker (hereinafter referred to as circuit breaker) is an outdoor distribution equipment with rated voltage of 12kV and three-phase AC 50Hz. It is mainly used for breaking and closing load current, overload current and short circuit current in power system. It is suitable for the protection and control of power distribution system of transformer substation and mining enterprise, more suitable for the rural power grid and places with frequent operation, especially for the needs of urban power grid and rural power grid transformation.
        This installation and operation manual specifies the main technical parameters, product structure, operation, installation, operation and maintenance principles and methods of the circuit breaker. The circuit breaker adopts three-phase pillar structure, which has the characteristics of stable and reliable breaking performance, no danger of combustion and explosion, maintenance free, small volume, light weight and long service life. 2) The circuit breaker adopts a fully enclosed structure with good sealing performance, which is helpful to improve the moisture-proof and anti condensation performance, and is suitable for use in high temperature and humid areas.
