Outdoor Disconnecting switch / isolator switch

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. Disconnector can be cooperated with motor drive mechanism CJ6 or manual mechanism CS14G.
