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.
