The ZW20-12 outdoor pole-mounted high-voltage vacuum circuit breaker is an outdoor high-voltage switchgear with a rated voltage of 12kV and three-phase AC 50Hz. It is mainly used for breaking and closing the load current, overload current and short-circuit current of the power system. It is suitable for protection and control of substations, industrial and mining enterprises, and urban and rural distribution networks, especially for places with frequent operations and domain network automation distribution networks.
This product is matched with the controller to meet the requirements of the distribution automation system and can reliably and effectively complete the traditional recloser function. It adopts a mature box-type sealing structure, which is filled with SF6 gas inside and has good sealing performance, so that it is not affected by the external environment. It is a maintenance-free product. Its spring operating mechanism adopts a direct-acting chain drive and a multi-stage tripping system, with high action reliability, and is an excellent product for pole-mounted circuit breakers.
