Myth About Sulfr hexafluoride Gas In Electrical Equipment

Apr 12, 2021 · From 0kV thru 800kV sf6 gas is my choice for the insulating and arc-extinguishing characteristics delivered by Sulfr hexafluoride. 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 Sulfr hexafluoride gas is jettisoned right through the arc zone thus assuring the thorough extinguishing of the arc.
