In Germany, this resulted in an industry-wide, voluntary self-commitment (starting in 1997, renewed in 2005) [SOLVAY et al., 2005]. This resulted in a reduction in SF 6 emissions related to electrical equipment from 50t of SF 6 in 1997 to 17t of SF 6 in 2015. Ongoing operation

Myth About insulating gas 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 sf 6. 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 Sulfr hexafluoride gas is jettisoned right through the arc zone thus assuring the thorough extinguishing of the arc.
