GW4-126kV Disconnector is developed product with advanced technology at the base of the original disconncetor. It is employed, at off-load condition, to switch high-voltage bus, applied an isolating distance between the high-voltage bus checked & maintained, or electric equipments such as circuit breaker and live high-voltage bus.

Disconnector GW4 series products are in design of double-supporting horizontal 3-pole-linkage and can be acted single-pole. It consists of base frame, supporting insulator and upper contactor. The revolving insulators are installed on the base with ball bearing inside, therefore it is quite easy to operated the disconnector.
