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 gaz sf6. it is heavier than air, and just as the old OCB’s were designed, the sf 6 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 thoroughGet price

Meiden develops groundbreaking high-voltage switchgear

gaz sf6 gas has a greenhouse effect 23,900 times that of carbon dioxide. The reduced use of sf 6 gas with a VCB can help contribute to the prevention of global warming. In addition, Sulfr hexafluoride decomposes into a harmful gas when the electrodes open and close in a GCB, and needs to be disposed of in accordance with the law. In a VCB, in contrast, gaz sf6 does not turn into a harmful gas and is recycleable. 3.Get price
