Outdoor High Voltage lsolation Switch

The 35kV turnkey disconnector set comprises the JLGW4-40.5(D)(W) disconnector body, cS11 or cs8-6D manual operatingmechanism, and transmission accessories, among others. it can also be paired with a C6 electric operating mechanism. The 110kVturnkey disconnector set features the JLGW4-126(D)(W) disconnector body, CS14G manual operating mechanism, andtransmission accessories, which can also be equipped with a CJ6 electric operating mechanism.This disconnector is a double-column, horizontally-actuated desian., Confiaured as unipolar, it features inter-pole connections viaconnecting rods when operating three poles simultaneously. Each unipolar segment comprises a base, post insulators, outletsockets, and contact heads, The two post insulators are mounted parallel and perpendicular to the base on the bearings at eachend. The main electrical components are mounted above the two pillar insulators, rotating approximately 90" along with theinsulators.
