Description

GW4-110,126,252(D)(W) High Voltage Disconnect Power 630A 1250A Isolator Switch

GW4 outdoor AC isolation 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 outdoor AC isolation 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.

Applictaion

The “GW9-10G” type of outdoor high voltage isolate  switch  is  the  high voltage switch equipment  of  single phase AC 50Hz. The  product  is  suitable  for power system with rated voltage 10kV to make or break power  supply  under circumstances  of  with  voltage and nonload.

The isolator is adopts isolated hook rod to operated.

Normal service conditions

1.The altitude does not exced 1000m;

2.The ambient air temperature:Maximum +40℃;Minimum:General Area -30℃,Paramos -40℃;

3.The wind pressure does not exceed 700Pa.(corresponding to 34m/s wind speed);

4.The earthquake intensity does not exceed 8 degrees;

5.The working situation is without frequent violent vibration;

6.The installation site of ordinary type isolator should be kept away  form  gas, smoke  chemical  deposition, salt-spray  fog, dust

and other explosive and corrosive maters that affect seriously insulation and conduction capability of the isolator.

7.Pollution-proof type isolator is applies to severe filthy conduction  area, however ,  it  shouldn’t  be  any  explosive  matters and

matters causing fire.

Overall and Installation Dimension

The isolator can be installed vertically or slant. Please see figure for overall and installation dimension
