Product Description

1.GW4-40.5 Manufacturers Supply 400A 630A 1000A Hv Disconnector

 

The GW4 AC high-voltage isolation switch is applicable to power systems over 10KV, used for no-load switch of high-voltage lines, and used for electrical isolation between the detected electrical equipment such as high-voltage bus bars and circuit breakers and live high-voltage lines. For the high voltage line no-load switch, high voltage bus under test, circuit breaker and other electrical equipment and live high voltage line electrical isolation.

The GW4 outdoor AC isolation switch is used for the maintenance of high-voltage bus, circuit breaker and other electrical equipment and the electrical isolation of high-voltage circuit when there is no load current. Provides visible insulation distance safety requirements when the main switch is in the off position; This product is double column horizontal open, the main switch, the left and right contacts should be rotated 90 degrees to the same side. The grounding switch is rotated and then linearly inserted to complete the whole process. Current varieties adopt parallel arrangement of double guide system, which increases traffic capacity and reduces material consumption. Actuator can adopt manual and electric, manual with CSA mechanism, electric with CJ11 mechanism; Based on the previous GW4 products, GW4 outdoor AC isolation switch has been further improved and improved. Compared with the previous GW4 products, there are many obvious improvements. The main blade material is copper, and the contact area is plated with a thick layer of silver. Wiring terminal conductive multilayer film with soft connecting element; The ground cutter is made of aluminum alloy conductive tube, the contact is copper thick silver plated, and the exposed steel parts are hot-dip galvanized or Dacromet. Thus, Gw4 series products, our factory has advanced structure, strong corrosion resistance, convenient operation, safe and reliable operation, mechanical and electrical stability and other advantages.
