ZW20-12 outdoor high voltage AC boundary vacuum circuit breaker

product information

Product name: ZW20-12 outdoor high voltage AC boundary vacuum circuit breaker

Category: high voltage components

Product introduction: ZW20B-12 outdoor pole-mounted high-voltage vacuum circuit breaker is an outdoor high-voltage switchgear with a rated voltage of 12kV and a three-phase AC 50Hz.

Overview of ZW20-12 outdoor high voltage AC boundary vacuum circuit breaker

The ZW20B-12 outdoor pole-mounted high-voltage vacuum circuit breaker is an outdoor high-voltage switchgear with a rated voltage of 12kV and a three-phase AC 50Hz. 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 power distribution networks, and is especially suitable for places with frequent operations and area network automation power distribution networks. This product is matched 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 a mature box-type sealing structure and is filled with SF6 gas. It has a good sealing performance, so that it is not affected by the external environment. It is a maintenance-free product. The spring operating mechanism adopts a direct-acting chain main drive and a multi-stage tripping system, which has high reliability and is a good product for pole-mounted circuit breakers.
