GW4 110KV Outdoor High Voltage Electric Disconnector Switch is a switch for high-voltage line in the no load flow,and the high voltage bus, circuit breakers and other electrical equipment maintenance and high voltage circuit of electrical isolation in.In the main switch in the off position can provide a visible insulation distance safety requirements;This product is a double column horizontal open type, main switch points, closing operation, the left, the right to the same side contact should be rotated 90 degrees. The grounding switch is the first rotary, linear insert again to complete the whole process. Current varieties using double conductive system parallel arrangement, increase the flow capacity, reduce the consumption of material. The actuator can adopt manual and electric, manual with CSA mechanism, electric with CJ11 mechanism; GW4 110KV Outdoor High Voltage Electric Disconnector Switch is on the basis of the previous Gw4 products,after further improvement and perfection of product improvement, compared with GW4 products in the past, there are many significant improvements, the main knife material with copper, contact a thick silver plating . Connecting terminal electrically conductive multilayer with soft connected component ; grounding knife material is aluminum alloy conductive tube, contact for copper thick silver plating, exposed steel parts are hot-dip galvanized or dacromet. Thus Gw4 products, our factory has advanced structure, strong corrosion resistance,easy to operate, safe and reliable operation, the advantages of electrical and mechanical stability.
