  • Installation guidelines for MV metal-enclosed switchgear

    Aug 03, 2020Insulating media 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).

  • Switchgear - Wikipedia

    A switchgear may be a simple open-air isolator switch or it may be insulated by some other substance. An effective although more costly form of switchgear is the gas-insulated switchgear (GIS), where the conductors and contacts are insulated by pressurized sulfur hexafluoride gas (SF 6). Other common types are oil or vacuum insulated switchgear.
