(H) GW4 series outdoor high-voltage single-phase disconnector (hereinafter referred to as disconnector) is a three-phase AC 50Hz outdoor high-voltage power distribution device with the rated voltage 12-40.5kV,suitable for 10-35kV power supply system for cutting off and closing the high-voltage line with voltage under non-load and for electrical isolation of the electrical devices under repair such as high-voltage bus and circuit breaker from the live high-voltage line.
It is also used to turn on/off a very small capacitive current and inductive current. Among them, the anti-pollution disconnector can satisfy the users in the heavy foul area, and can effectively solve the pollution flashover problem occurred during the operation of general disconnector.
