1.10kV 35kV outdoor high voltage Disconnector 3 phase isolatOR Switch GW1 600A 800A
GW1 series outdoor high voltage isolator 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.
