  • An Introduction to Gas Insulated Electrical Substations

    A GIS is a high voltage substation in which the major conducting structures are contained within a sealed environment with a dielectric gas known as sulfur hexafluoride gas (SF6) as the insulating medium. In comparison, a conventional (AIS) or Air-Insulated Substation, uses atmospheric air as the dielectric gas medium, as these types of substations are almost always located at outdoor locations.
