35kV 40.5kV Gas Insulated Switchgear Expandable Compact Switch Cabinet

Usage Conditions of LYF-40.5 Series gas insulated switchgear

LYF-40.5 is suitable for the customized use of MV GIS switchgear in the following locations

1. Compact type secondary substation
2. Small industrial and mining enterprises
3. Wind power plants
4. Hotels, shopping centers, ffice buildings, commercial centers and so on

Working environment conditions
1. Ambient air temperature: upper limit +40 °C lower limit -40 °C;
2. Air relative humidity: the daily average is not more than 95%, and the monthly average is not more than 90%;
3. Altitude ≤ 1500 meters (under standard inflation pressure);
4. The seismic intensity does not exceed 8;
5. Places without fire, explosion, serious pollution, chemical corrosion and severe vibration.

Special conditions
MV switchgear manufacturers and end users must agree on special operating conditions that differ from normal operating conditions.
If particularly harsh operating environments are involved, the manufacturer and supplier must be consulted.
When the electrical equipment is installed above 1500 meters above sea level, it should be specified so that the pressure can be adjusted during manufacture. When this pressure is adjusted, the life of the switchgear itself has no significant effect.
