DIELECTRIC FLUID COMPOSITION

摘要

A dielectric fluid composition with high electrical strength characterized by a gas mixed with the vapor from a first fluid having a high vapor pressure at a low temperature and the vapor from a second fluid having a low vapor pressure at a low temperature to effect a mixture having a higher electrical strength than any component thereof over a temperature range from about -20 DEG C. to -40 DEG C. to about +120 DEG C. to +140 DEG C., with the vapor pressure of the mixture at the highest temperature being about one to two atmospheres. Also, the mixing of low and high cost liquids to obtain a low cost liquid with a vapor with an electrical strength equivalent or better than the best vapor over a wide temperature range.
