Sulphur hexafluoride (SF6) is a man-made gas comprising of one sulphur and six fluoride atoms. SF6 is extremely chemically stable, non-flammable and highly electronegative, with an excellent dielectric property of approximately 2.5 times more than air. Therefore it is commonly used in electrical switchgear, transformers

SF6 gas Mixtures Decomposition for subway. PD can cause decomposition of sf 6 gas, resulting in the production of various low-fluorine sulfides, such as SF 4, SF 3, SF 2, and S 2 F 10. 1 – 3 Because of the presence of trace impurities, such as H 2 O and O 2, in the equipment, these low-fluorine sulfides generate many more stable decomposition

History of SF6

2021-3-16SF6 can be heated without decomposition to 500&C in the absence of catalytic metals. SF6 is non-flammable and hydrogen, chlorine, and oxygen have no action on it. SF6 is insoluble in water and is not attacked by acids. Toxicity of arc products. Toxic decomposition products are formed when SF6 gas is subjected to

The first generation of SF6 circuit breakers was the lower voltage classes of 72kV and 145kV. As SF6 breaker technology improved, circuit breaker manufacturers introduced a dual pressure design for 145kV through 800kV applications, as well as air-blast breakers utilizing SF6 as the line-to ground dielectric insulation.
