Mitsubishi Electric Comes Up with New Gas-Insulated ... 2 switchgear technologies are expected to curb the emissions of powerful greenhouse gases, which absorb heat in the lower atmosphere and eventually result in global warming. The technologies will help in further reducing the size of switchgears and thus minimize the use of Sulfur Hexafluoride (SF6) gas, which has global warming potential.
The growing importance of gas-insulated switchgear· Users: Users are utilities and industries that use HV equipment. Gas Insulated Switchgear . Photo: ABB. Gas insulated switchgear (GIS) is very compact form of switchgear. Because of the use of SF6 (sodium hexafluoride) insulation, the size of the switchgear reduces drastically. This product is normally used in medium and high voltage application.
High Voltage Switchgear | Electrical4U· The power system deals with voltage above 36KV, is referred as high voltage switchgear.As the voltage level is high the arcing produced during switching operation is also very high.

Switchgear - Wikipedia for lower voltages may be entirely enclosed within a building. For higher voltages (over about 66 kV), switchgear is typically mounted outdoors and insulated by air, although this requires a large amount of space. Gas-insulated switchgear saves space compared with air-insulated equipment, although the equipment cost is higher.
