Product Description

Product Description

summarize
ZW20-12 type outdoor high-voltage vacuum circuit breaker on the column is an outdoor high-voltage switchgear with rated voltage 12kv and three-phase AC 50HZ. It is mainly used to break and close the load current, overload current and short circuit current of the power system. It is suitable for the protection and control of substations, industrial and mining enterprises and urban and rural distribution networks, especially for places with frequent operations and urban automatic distribution networks. This product is compatible with the controller, which can meet the requirements of the distribution automation system, and can reliably and effectively complete the traditional recloser function. It adopts mature box-type sealing structure, filled with SF6 gas, has good sealing performance, so that it is not affected by the external environment, is a maintenance-free product.
