1. FLW34 Type Outdoor Pole-Mounted 12kv 24kv SF6 Load Break Switch
FLW34 Type Outdoor Pole-Mounted 12kv 24kv SF6 Load Break Switch is suitable to the distribution network with rated voltage 12/24kV, rated current 400/630A, 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.
