Blue gas-insulated switchgear | References | Siemens ... blue GIS 8VN1 from Siemens is an innovative, compact switchgear product. 8VN1 doesn't use Sulfur hexafluoride (SF6 gas) or other fluorine gases as an insulating and interrupting medium. Instead of greenhouse gases, it uses compressed synthetic air (so called clean air) technology to provide insulation between live parts and the earthed metal housing.[email protected]

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.
GIS vs AIS - Life cycle assessment - EEP analysis of the contribution made by distribution grids to the global warming potential (GWP) in Germany shows that the greatest share is attributable to ohmic losses in cables, transmission lines and transformers. At present, SF6 emissions from medium-voltage switchgear contribute less than 0.005 % to the global warming potential in Germany.
