GN19-12(C) indoor HV disconnect switch applies to power system of rated voltage below 12kV,three phase AC 50/60Hz. It is equipped with CS6-1 manual-operating mechanism and is used to break and make circuit under no-load. There are additional pollution type and high-altitude type.
1. Altitude: 1000m~3000m;
2. Ambient temperature: -30℃ ~+40℃ ;
3. Relative humidity: daily average ≤ 95％ , monthly average ≤ 90％ ;
4. Earthquake intensity: ≤ 8 grade;
5.Wind pressure: ≤ 700pa(wind speed 34m/s)
6. Applicable occasions should free from inflammables, explosives, corrosives and severe vibration.
1. Scientific design and simple structure.
2. Large clearance between gaps.
