Gw1-12 Outdoor High Voltage Isolating Switch. are high voltage switchgears of monopole structures and be applied for the connection and disconnection of circuit under voltage without loading. kNife switch with CS mould manual operating mechanism can prevent disoperation such as switching in etc. On line earthing wires. And the operating staff needs not to clients for heavily polluted areas and can make effective solutions on the pollution flashover during the operation of disconnecting switches.
Our Gw1-12 Outdoor High Voltage Isolating SwitchIt is a new type of patented product designed by our factory according to the current national standard and IEC standard, aiming at a series of problems existing in the original GWl type switch. The switch itself has a grounding knife, and the CS manual mechanism produced by the factory can effectively prevent misoperations such as "connecting the ground wire with power and closing with the wire", and the operator does not need to hang another ground wire during line maintenance. The product has excellent electrical and mechanical properties. It is a replacement product of the current 12KV outdoor isolating switch.
