  • Gas-Insulated Substations - GIS | EEP - Electrical Engineering Portal

    Gas-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. As a result, GIS is more reliable and requires less maintenance than AIS.
