SF6: Does its Impact Outweigh its Benefits? | T&D World gas has been used extensively since the mid 1950s to replace oil as an insulator in electric equipment, and more recently in gas insulated switchgear (GIS) and gas insulated lines (GIL). It is also used in medium voltage switchgear primarily outside the United States and extensively worldwide in low switching capacity gear.
Thermal stability of SF6 associated with metallic ...iopscience.iop.org/article/10.1088/0022-3727/40/22/01511/2/2007· SF 6 is generally treated as thermally stable and inert for applications below 500 °C. This work investigates the thermal stability of pure SF 6 gas under 1.2 atm pressure between 200 and 450 °C in the presence of construction metals (Cu, Al), without any applied electric field. The obtained experimental results indicate that SF 6 may react with metallic surfaces forming solid and gaseous by ...
