| Model NO. | Solid insulation vacuum |
| Rated voltage | 12kV |
| Series | SIV |
Description:
Now all of the world is considering environmental protection issues,so if SF6 is considered not environmentally friendly, you can use solid material.
And technical requirement can reach SF6‘s level.And already passed E2 level.

Usage Environment:
Altitude：Less than 3000m(The most 5000m)
ambient temperature：-40℃--40℃，The average daily temperature is not higher than 35°C
verage daily relative humidity:95% Monthly average relative humidity: 90%
Daily average saturated vapor pressure: ≤2.2×10-3Mpa Monthly average saturated vapor pressure: ≤1.8×10-3Mpa
Earthquake intensity: no more than 8 degrees
Horizontal acceleration: synthetic seismic wave 0.25g, sinusoidal resonance beat wave 0.15g
Low temperature and cold area: no SF6 gas application, no need to consider the low temperature operation of SF6 gas, and it can operate normally at -45C.
Plateau area: no need to consider the influence of plateau atmospheric pressure on insulation performance
Strong wind and sand area: The safety protection level of the solid insulation ring main unit is IP67, and the control circuit room adopts special treatment to ensure long-term operation in strong wind and sand areas.
Coastal wet areas: epoxy resin sealing, anti-moisture, anti-salt spray corrosion, to ensure long-term use in coastal areas. Areas with high environmental protection requirements: The impact of SF6 gas on atmospheric warming has been highly regarded, and the solid ring main unit has eliminated SF6 gas, which does not cause any pollution and harm to the environment and people.
