Abstract :
The decomposition of sulfur hexafluoride (SF6) in overheated electric equipment at different temperature in low humidity was simulated in the study. SF6 is very stable and not significantly decomposed at 200°C, 250°C and 300°C. SF6 is significantly decomposed at 350°C. SF6 is more easily to be decomposed and decomposed more rapidly at higher temperature.
