Product Description

Production View

Zw20-12 outdoor column high voltage vacuum circuit breaker is an outdoor high voltage switchgear with rated voltage of 12kV and three-phase AC of 50h.

It is mainly used to turn on and off the load current, overload current and short-circuit current of power system. It is suitable for protection and control of substation, industrial and mining enterprises and urban and rural distribution network, especially for places with frequent operation and automatic distribution network of regional network.

This product is matched with the controller, which can meet the requirements of distribution automation system and complete the traditional recloser function reliably and effectively. It adopts a mature box sealing structure and is filled with SF6 gas.
It has good sealing performance, so that it is not affected by the external environment.

It is a maintenance free product. The spring operating mechanism adopts direct acting chain drive and multi-stage tripping system, with high action reliability. It is a good product of column circuit breaker.
