GW9-12 Outdoor disconnector （isolating switch）12kv
GW 9 Series Outdoor H.V. Isolating switch is used for rated voltage 10kV power system. The isolation section is available in porcelain insulator or polymer insulator.
400 ~ 1000A disconnecting switch
Advantages: light weight, double - side contact surface (up to 40 mm), its performance and service life are more than twice as long as the ordinary isolation switch.
Environment condition
1, the altitude does not exceed 1000m.
2, The ambient air temperature:Maximum+40°C;Minimum:General Area-30°C ,paramos-40°C .
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 without frequent violent vibration.
Products features
1.The installation site of ordinary isolator should be away from gas, smoke chemical deposition, salt, spray fog, dust and other explosive and corrosive materials that affect seriously insulation and conduction capability of the isolator.
2.Pollution proof type isolator is apples to severe filthy conduction area; however, it shouldn't be any explosive matters and matters causing fire
