Overview:

The SF6XGN-40.5 series gas-filled cabinet is a fully enclosed, fully insulated, compact ring main switchgear system designed for 40.5kV distribution systems. This switchgear, with its expandability, allows for both full modular and semi-modular configurations, offering unique flexibility. The stainless steel gas chamber is filled with SF6 gas, which completely seals all live components and switches from the external environment. This fully sealed system ensures that the internal switches and all live parts are unaffected by external environmental changes, guaranteeing high reliability, personnel safety, and practical maintenance-free operation. It can meet various power distribution configuration requirements.

Operating Environmental Conditions:

• Altitude: ≤2000 meters;
• Ambient temperature: -30°C to +40°C;
• Relative humidity: daily average ≤95%, monthly average ≤90%;
• Seismic capability: 8 degrees, with ground horizontal acceleration ≤0.4g and ground vertical acceleration ≤0.2g;
• Suitable for locations free from severe vibration, shock, fire, or explosion hazards.

Application Range:

The SF6XGN-40.5 series gas-filled cabinet offers compact structure, full enclosure, full insulation, long lifespan, small footprint, safety, reliability, and resistance to environmental conditions. It is widely used in compact secondary substations, small industrial and mining enterprises, wind power plants, hotels, shopping malls, office buildings, commercial centers, subways, and other similar fields.
