  • An Introduction to Gas Insulated Electrical Substations

    2020-10-6What is a Gas Insulated Substation? A gas insulated substation (GIS) is a high voltage substation in which the major conducting structures are contained within a sealed environment with a dielectric gas known as SF6, or sulfur hexafluoride gas as the insulating medium. In comparison, a conventional (AIS) or Air-Insulated Substation, atmospheric air is the
