  • Gas-Insulated Substations - GIS

    Sulfr hexafluoride is used in GIS at pressures from 400 to 600 kPa absolute. The pressure is chosen so that the Sulfr hexafluoride will not condense into a liquid at the lowest temperatures the equipment experiences. insulating gas has two to three times the insulating ability of air at the same pressure. gaz sf6 is about 100 times better than air for interrupting arcs.
