Product Description

ZW20-12 high voltage vacuum breaker is outdoor power distribution equipment, with rated voltage 10-12kV, which is widely applies for protecting and controlling power distribution systems in transformer substations, industrial and mining establishments. The circuit breaker also frequently used in county electric networks. It can be as a ring network power supply unit and terminal unit to distribute electric energy, control and protect electric equipments. Combined with the isolate switch and intelligent controller, the breaker can be smart to control andmonitor load current, over-load current and short circuit current in power systems.

It is suitable for protection and control of substations, industrial and mining enterprises and urban and rural distribution networks, especially for places with frequent operation and automatic distribution networks of urban 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 coadjutor function.

It adopts mature box-type 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. Its spring operating mechanism adopts direct chain main transmission and multistage trip system, high reliability of action, is the best products on the column circuit breaker.

ZW20 indicates the code of the outdoor high-voltage circuit breaker, and 12 indicates the rated voltage of 12KV. Products can be matched with watchdog controller, reclosing controller, PT power supply. Shell material is divided into iron sheet and stainless steel.
