Product Description

ZW20-12F/G series outdoor high-voltage vacuum circuit breaker (hereinafter referred to as circuit breaker) is outdoor power distribution equipment with rated voltage 12kV, three-phase AC 50Hz. It adopts vacuum arc extinguishing and SF6 gas as insulating medium, and is an improved product of ZW20-12F type column vacuum circuit breaker. The box adopts the gas sealing, explosion-proof and insulating structure technology of VSP5 introduced from Toshiba, Japan, and the inlet and outlet conduits have also been improved, with excellent overall sealing performance. Its spring-operated mechanism is miniaturized and optimized for reliability and stability, with direct-acting chain main drive and multi-stage decoupling system, Low temperature rise. Therefore, ZW2-12F outdoor column vacuum circuit breaker is a maintenance-free product, which is the best product in column circuit breaker.
 

ZW20-12F is mainly used to open and close the load current and short-circuit current of 10KV power system. It is suitable for protection and control in substations and distribution systems of industrial and mining enterprises, and more suitable for frequent operation of the power grid. This product is matched with the controller and has excellent recloser function, which can meet the requirements of distribution automation system.
