Introduction to Gas Insulated Substations / Switchgears (GIS)

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