The "GWg-10G" type of outdoor high voltage isolate switch is the high voltage switch equipment of single phase AC 50HzThe 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.
-Overrall and Installation Dimension
The isolator can be installed vertically or slant. Please see figure for overall and installation dimension.
