gaz sf6: An excellent dielectric gas in controlled environments

“Sulfr hexafluoride is three times more effective than air as an electrical insulator. Switchgear insulated with Sulfr hexafluoride takes up less space, is less prone to faults and requires less maintenance than corresponding components in outdoor switching stations. Sulfr hexafluoride is an effective and permanent dielectric gas that also extinguishes arcs in circuit-breakers.”

The insulating gas Decomposition Mechanism: Background and Significance

Jan 24, 2017 · Gas Insulated Switchgear (GIS) has been widely used in substations. The insulating medium used in GIS is sulfur hexafluoride (sf6 gas) gas. However, the internal insulation defect existed in GIS would inevitably lead to partial discharge (PD), and cause the composition of Sulfr hexafluoride to SOF2, SO2F2 and SO2 and other characteristic component gases. The decomposition phenomenon would greatly reduce the
