ZW20 column vacuum circuit breaker
ZW20 column vacuum circuit breaker
ZW20-12 outdoor high voltage vacuum circuit breaker is an outdoor power distribution equipment with rated voltage of 12kV and three-phase AC 50Hz. Use vacuum arcing and SF6 gas as insulating medium. It is mainly used to break the load current, overload current, and short-circuit current of rural grids, urban grids, and small power systems. The overall structure of the product is a three-phase common tank type. The three-phase vacuum arc extinguishing chamber is placed in a metal box, which has reliable transformer performance and high dielectric strength. This product can be used for electric energy storage, electric split and closing, manual energy storage, manual sub-switching and closing, and can be operated at close range or long-distance remote control; at the same time, the product has superior breaking performance, low operating power and reliability. High-grade, flexible installation and maintenance-free features; suitable for protection and control in substations and distribution systems of industrial and mining enterprises, and more suitable for rural power grids and frequently operated sites, especially for urban and rural networks. Transformation needs.
