  • Myth About SF6 Gas In Electrical Equipment

    Apr 12, 2021 · From 0kV thru 800kV SF6 is my choice for the insulating and arc-extinguishing characteristics delivered by SF6. it is heavier than air, and just as the old OCB’s were designed, the SF6 chamber and contacts are designed much like they were, whereby a “puff” of SF6 gas is jettisoned right through the arc zone thus assuring the thorough extinguishing of the arc.

    A transformer’s life is determined by the health of the insulation system. If one tiny piece of the insulation in a critical location fails, electrically or mechanically, the transformer is potentially doomed.
