Gas Insulated or Air Insulated Switchgear arguments exist around SF6 Gas Insulated (GIS) and Air Insulated (AIS) switchgear. Recently we had to change a GIS design to AIS due to an instruction from one of our clients. His concern is the global warming potential of SF6. While understanding the …[email protected]

COLLISIONAL DECOMPOSITION OF SF6- - NIST· PDF file35A2 at higher energies. The decomposition cross sections of SF6- in collisions with N2 are similar to those observed for rare gas targets. The target-independent features of SF6-decomposition can be qualitatively explained using a two-step model in which collisional decomposition is followed by unimolecular decomposition. 955 8 7-1 a Ar 0/ a 6 ...
Gas-insulated Switchgear (GIS) Testing - OMICRON switchgear (GIS) is very compact and therefore represents a space-saving alternative to classic air-insulated installations. The low insulation distances are guaranteed by the high dielectric strength of the sulfur hexafluoride (SF6) gas. A perfect condition of the insulation is essential for ensuring a reliable operation of GIS.

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.
