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 gaz sf6 will not condense into a liquid at the lowest temperatures the equipment experiences. sf 6 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.Get price
