GW9-12(W) series outdoor AC high voltage isolation switchDetailed product description：

GW9-12 (W) series outdoor high-voltage isolation switch is a single pole structure high-voltage switchgear used for opening and closing circuits in outdoor 12 kV line networks with voltage and no load. Equipped with fixed hooks and self-locking devices, flexible and reliable, using insulated hook rods for operation. The anti pollution outdoor high-voltage isolation switch can meet the requirements of users in severely polluted areas and effectively solve the problem of pollution flashover during the operation of the isolation switch

GW9-12 (W) series outdoor AC high voltage isolation switch operating environmental conditions
1. Altitude not exceeding 1000m;
2. Surrounding air temperature: upper limit+40 ℃, lower limit -30 ℃ in general areas, -40 ℃ in high-altitude areas;
3. The wind pressure shall not exceed 700Pa (equivalent to a wind speed of 34m/s);
4. The seismic intensity shall not exceed 8 degrees;
5. Places without frequent and severe vibrations;
6. Ordinary installation sites should be free of gases, vapors, chemical deposits, salt spray, dust, and other explosive and corrosive substances that seriously affect the insulation and conductivity of isolation switches;
7. Anti pollution type is suitable for heavily polluted areas, but should not contain substances that can cause fires or explosions.
