FLW pole-mounted SF6 load switch
FLW pole-mounted SF6 load switch
FLW series outdoor communication high-voltage SF6 load switches are suitable for outdoor three-phase AC distribution systems with a rated voltage of 12kV and a rated frequency of 50Hz, used for switching load current and closing overload current. This product uses SF6 gas as the arc extinguishing medium, which has excellent arc extinguishing performance; the structure of the load switch is a three-phase common box type, with three-phase linkage operation, which can be operated manually on-site or remotely from the central control room; this product is suitable for substations, industrial and mining enterprises, as well as urban and rural network automation distribution networks and places with frequent operations.
