Myth About sf6 gas Gas In Electrical Equipment

Apr 12, 2021 · From 0kV thru 800kV sf 6 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 insulating gas chamber and contacts are designed much like they were, whereby a “puff” of sf6 gas gas is jettisoned right through the arc zone thus assuring the thorough extinguishing of the arc.

Sulfur hexafluoride - Wikipedia

Sulfur hexafluoride or sulphur hexafluoride, is an extremely potent and persistent greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density of
