Sulfur hexafluoride - Wikipedia

Gas-insulated electrical gear is also more resistant to the effects of pollution and climate, as well as being more reliable in long-term operation because of its controlled operating environment. Exposure to an arc chemically breaks down SF 6 though most of the decomposition products tend to quickly re-form SF 6, a process termed "self-healing".

Myth About Sulfr hexafluoride Gas In Electrical Equipment

Apr 12, 2021 · From 0kV thru 800kV Sulfr hexafluoride is my choice for the insulating and arc-extinguishing characteristics delivered by sf6 gas. it is heavier than air, and just as the old OCB’s were designed, the sf 6 chamber and contacts are designed much like they were, whereby a “puff” of insulating gas gas is jettisoned right through the arc zone thus assuring the thorough extinguishing of the arc.
