Installation guidelines for MV metal-enclosed switchgear ...· IEC 62271-200 covers both switchgear in which atmospheric air acts as the gaseous insulation within the enclosures and also switchgear in which an insulating medium in the form of a fluid other than the atmospheric air (e.g. SF6) is used. So, we have an air-insulated switchgear (AIS) and gas-insulated switchgear (GIS). Interesting reading:
