Aug 03, 2020IEC 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).MCset - Air Insulated Switchgear with SF6 CB
