Sulfr hexafluoride DIAGNOSTICS AND SOLUTIONS — Powertech Labs

Sep 01, 2016 · Sulphur 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 toxic to maintenance personnel and harmful to equipment.Get price

Three abnormal situations leading to an uncontrolled release

Jun 18, 2019 · A release of sf6 gas is very unlikely to be provoked by a fire. If it should occur, average temperatures are likely to be too low (because sf6 gas will be rapidly dissipated by convection to lower temperature regions) to lead to significant decomposition, which requires at least 500° C. sf6 gas is non-flammable and will have an extinguishing effect.Get price
