Abstract
Electronegative, normally gaseous, fluorinated compounds with sulfur at valence state 2 act as good dielectric gases alone or in combination with sulfur hexafluoride. In particular bis (trifluoromethyl) sulfide has a higher dielectric strength than sulfur hexafluoride when used alone and increases dielectric strength of sulfur hexafluoride in blends.
