Gas Insulated Substations | Electrical Substation ... Insulated Substations (G.I. S) Definition : A gas insulated substation (GIS) is a substation that uses a superior dielectric gas, sulfur hexafluoride (SF6), high-voltage. The basic principle of gas-insulated equipment : Is that the high-voltage current- carrying parts are within a metal enclosure and are held in a concentric configuration by cast epoxy spacer insulators.
