1. Reliable operation. 2. Supplier for China State Grid. 3. IEC and GB (China standard) standard 4. 15kV,24kV,36kV.
GW 9 Series Outdoor H.V. Isolating switch used for rated voltage 10-38kV power system. The isolation section available in porcelain insulator or polymer insulator.
Normal conditions of use1,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.
Installation NoteThe installation site of ordinary isolator should be away from gas,smoke chemical deposition,salt,spray fog,dust and other expiosive and corrosive materials that affect seriously insulation and conuction capability of the isolator.Pollutionproof type isolator is apples to severe filthy conduction area.however.It shouldn' be any explosive matters and matters causing fire
