Product Details

HGW1 single-pole high-voltage disconnector is used to cut off or connect the circuit when there is voltage but no load, and to electrically isolate the high-voltage equipment under maintenance. The GW1-12g switch has a grounding knife, which can effectively prevent the misoperation of hanging the ground wire with power on and closing the switch with the ground wire, thereby improving the operational safety.
