  • SF6 DIAGNOSTICS AND SOLUTIONS — Powertech Labs

    Sep 01, 2016Sulphur hexafluoride (SF 6) is a non-toxic, odourless gas with unique electrical properties. For over 50 years, it has been used in high-voltage gas-insulated switchgear (GIS), where its excellent dielectric and arc-quenching properties make it an ideal insulating gas for medium- and high-voltage equipment. However, when the gas decomposes, it forms decomposition products that are

  • The decomposition products of sulfur hexafluoride (SF6

    Nov 01, 2007Based on the previous description, the identified products in the SF 6 decomposition system were S 2 OF 10, CF 4, COF 2, F 2, HF, H 2 S, NF 3, F 2 O, SiF 4, SO 2, S 2 F 10, SF 4, SO 2 F 2, SOF 2, SOF 4 and S 2 O 2 F 10. For example , the hydrolysis reaction of SF 6 with water may occur in the presence of an unvented indoor combustion source to produce HF and H 2 SO 4.
