Description
GN19-12 indoor HV disconnecting switch applies to power system of rated voltage below 12kV, 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, high-altitude type and power indicating type.
Environment condition
- Ambient temperature: max. +40°C min. -25°C
- Altitude: ≤1000m
- Wind pressure: ≤700Pa (equals to wind speed 34m/s)
- Relative humidity: daily average ≤95%, monthly average ≤90%
- Earthquake intensity: ≤8 degree
- No corrosive, explosive or flammable gas, no violent vibration
