Mostly purpose

The zw6-12outdoor hv vacuum breaker (short for breaker)is a kind of outdoor hv switching devices used in three-phase AC 50hz,12kv.it is used for breaking and making load current and short-circult current in power system.especiallu in the case of frequently operation. matching with ct23 spring operating machanism,the breaker can realize electric or manual energy storage and electric switch on/off. based on customer’s requirements,100/5,200/5,400/5,600/5 current transformer can be installed into the breaker, the JSZR-10W dry voltage transformer is build-in,and with fuse protection more,it realizes own rig net opereting power and provides operating power for reclosers or telemechancs terminals. with right control systems it can be a recloser or sectionalizer,it is an ideal choice for city and country electric network non-oil rebuild.
