Myth About sf 6 Gas In Electrical Equipment

Aug 24, 2017 · From 0kV thru 800kV Sulfr hexafluoride is my choice for the insulating and arc-extinguishing characteristics delivered by Sulfr hexafluoride. 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 Sulfr hexafluoride gas is jettisoned right through the arc zone thus assuring the thorough extinguishing of the arc.Get price

Gas insulated power transformers: A growing technology - EE

Mar 12, 2018 · Gas insulated transformers (GITs) have been in use since the 1960s, but use has been restricted due to higher costs and other reasons. Gas is used as an insulating and cooling agent in gas insulated transformers. Sulphur hexafluoride (SF 6) is the main gas used in these types of transformer at present although other gases are under development. The main advantage of gas insulated transformers is that they are environmentally friendly and can be recycled easily.Get price
