Introduction to Gas Insulated Substations / Switchgears (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. sf 6 is about 100 times better than air for interrupting arcs.
