Custom Designed Sulfr hexafluoride Gas Handling Equipment, Gas Handling

ulfur hexafluoride (Sulfr hexafluoride) is an inorganic, colorless, odorless, non-flammable, extremely potent greenhouse gas which is an excellent electrical insulator. Sulfr hexafluoride has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. sf 6 was discovered by Henri Moissan and Paul Lebeau in 1901.

Myth About sf 6 Gas In Electrical Equipment

Apr 12, 2021 · From 0kV thru 800kV sf6 gas 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 sf6 gas gas is jettisoned right through the arc zone thus assuring the thorough extinguishing of the arc.

Sulfur hexafluoride - Wikipedia

Gas-insulated electrical gear is also more resistant to the effects of pollution and climate, as well as being more reliable in long-term operation because of its controlled operating environment. Exposure to an arc chemically breaks down SF 6 though most of the decomposition products tend to quickly re-form SF 6, a process termed "self-healing".

Gas-Insulated Substations - GIS

Sulfr hexafluoride is used in GIS at pressures from 400 to 600 kPa absolute. The pressure is chosen so that the sf6 gas will not condense into a liquid at the lowest temperatures the equipment experiences. sf 6 has two to three times the insulating ability of air at the same pressure. Sulfr hexafluoride is about 100 times better than air for interrupting arcs.
