Product Description

ZW20-12 Outdoor Vacuum Circuit Breaker with SF6 Gas Insulation

ZW20-12 outdoor vacuum circuit breaker with SF6 gas insulation, is outdoor high voltage switch equipment with rated voltage of 12kV and three phase AC 50Hz. It is mainly used for breaking and closing load current, overload current and short-circuit current of the power system. The circuit breaker is suitable for application as protection and control in transformer stations, industrial and mining enterprise as well as the urban and rural distribution networks, and it is particularly suitable for places with frequent operations and automated distribution networks in urban networks. The product is matched with the controller to meet the requirement of a distribution automation system, and it can be used for reliably and effectively finishing functions of the traditional auto recloser. The circuit breaker adopts mature case type sealing structure, the inside is filled with SF6 Gas, so it has excellent sealing performance so as not to be affected by external environment, and it is a maintenance-free product. The spring operating mechanism adopts straight chain main transmission and a multi-stage tripping system, the reliability of actions is high, and it is an excellent product of on-pole circuit breaker.
