  • Apparatus with dielectric gas mixtures in substantially uniform field
    Patent number: 4204084
    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.

  • Electrical device with fluorinated divalent sulfur dielectric gas
    Patent number: 4166798
    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.

  • Gaseous dielectric mixtures for suppressing carbon formation
    Patent number: 4071461
    Abstract: Carbon formation on voltage breakdown and sparking, and consequent carbon deposits on insulators and other surfaces, is suppressed in dielectric gases of halogenated alkanes by adding SF.sub.6 and/or CO.sub.2 to the halogenated alkane to form a gaseous dielectric mixture. Moreover, certain of the gaseous dielectric mixtures evidence unexpectedly high dielectric breakdown voltages. The gaseous dielectric mixtures are useful in high voltage coaxial lines, in transformers, in minisubstations, and the like.

  • Gaseous dielectric compositions
    Patent number: 4052555
    Abstract: Perfluorinated ethers evidence useful properties as gaseous dielectrics and do not exhibit a high carbon tracking tendency, which is commonly a problem with halogenated alkanes. Mixtures of the perfluorinated ethers with SF.sub.6 and/or CO.sub.2, in critical proportions which are specific to each system, evidence improved dielectric breakdown voltages. The perfluorinated ethers and mixtures of the perfluorinated ethers with SF.sub.6 and/or CO.sub.2 are useful in high voltage coaxial lines, transformers, minisubstations, and the like.
