Differences Between Fully Insulated Gas-Insulated Switchgear and Semi-Insulated Switchgear
Aug 05,2025
Fully insulated gas-insulated switchgear manufacturer gas insulation layer switchgear, generally called semi-insulated layer switchgear, gas insulation layer switchgear alias fully insulated layer switchgear, the difference lies in:
1. The spacing between the inflation and insulation layer cabinet of the fully insulated gas-insulated switchgear manufacturer is only 1/3 of that of the gas insulation layer cabinet, greatly reducing the specifications of high-voltage switchgear.
2. All insulating materials of fully insulated layer gas-insulated switchgear from the fully insulated gas-insulated switchgear manufacturer: using SF6, N2 and other gases or their composite gases as insulating materials, with strong insulation performance.
3. Electrical clearance of fully insulated gas-insulated switchgear manufacturer: the insulation performance of the insulating gas is much better than that of gas, and the electrical clearance of the fully insulated layer gas-insulated switchgear cabinet is much lower than that of the semi-insulated layer cabinet.
4. Product equipment specifications of fully insulated gas-insulated switchgear manufacturer: due to the small electrical clearance, the fully insulated layer cabinet is much smaller than the same-level semi-insulated layer cabinet, occupying less space.
5. Product altitude effect of fully insulated gas-insulated switchgear manufacturer: the main circuit components of the fully insulated layer gas-insulated switchgear are placed inside the inflation chamber, with stable operating pressure. They are not affected by altitude. The insulation function of semi-insulated thermal insulation ring cabinets is directly affected by altitude. Standard products are used below 100m, and higher altitudes require special design.
6. Product pollution effect of fully insulated gas-insulated switchgear manufacturer: pollution does not easily affect the inflation isolation of fully insulated ring cabinets, suitable for polluted areas. Semi-insulated gas-insulated switchgear is directly affected by pollution.
