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. sf6 gas has two to three times the insulating ability of air at the same pressure. Sulfr hexafluoride is about 100 times better than air for interrupting arcs.
