Myth About sf 6 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 gaz sf6 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.
