  • Gas-Insulated Substations - GIS

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