Myth About sf6 gas Gas In Electrical Equipment

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