Product Description
Pole Mount Type Sf6 Gas Insulated Load Break Switch, 12kv, 24kv, 38kv
Product Description
GPS type outdoor pole-mounted HV AC SF6 insulation load break switch is suitable to the distribution network with rated voltage 12-40.5kV, rated current 630A, three-phase AC 50/60Hz to open and close the load current and short circuit current in the power system. It can automatically disconnect the distribution line segment in which the fault occurred. Equipped with the advanced electronic controller, the switch can be for manual operation, electric operation and remote operation. The electronic controller is installed in a stainless steel cabinet, so it can be used in all kinds of climatic conditions. The wire and wireless modems can be also installed in the cabinet to realize remote monitoring and control. Simple, convenient and quick pole mounting can lower the installation cost.
