ABSTRACT:
Dielectric gas mixtures are described with improved dielectric strength in uniform fields compared to pure sulfur hexafluoride. Sulfur hexafluoride is mixed with about 1 to about 10 mole % of a noble gas such as helium, argon, krypton or neon and used in a device wherein the dielectric gas is subjected to a substantially uniform field such as compressed gas insulated cable.
