Switchgear - Wikipedia 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.
Frequently Asked Questions: Regulation for Reducing Sulfur ...· PDF file1/22/2019· 1. Are all gas insulated switchgear (GIS) owners subject to this regulation, even if the GIS owner is not an electric utility? Yes. This regulation applies to all owners of GIS equipment that contains sulfur hexafluoride (SF 6). The regulation makes no distinction as to whether or not a GIS device is owned by an electric utility. 2.
ABB achieves breakthrough in switchgear technology with ... addition to the 170 kilovolt (kV) high-voltage GIS, ABB will also install medium voltage GIS with the new gas mixture.
