  • Gas-Insulated Substations - GIS

    6 mins readNov 10, 2010Gas-Insulated Substations – GIS The atmospheric air insulation used in a conventional, air-insulated substation (AIS) requires meters of air insulation to do what SF6 can do in centimeters. GIS can therefore be smaller than AIS by up to a factor of 10.
