The dielectric strength of noninflammable synthetic insulating oils

THE SUBSTITUTION of chlorine for hydrogen in the hydrocarbon molecule produces marked effect not only on the physical and chemical properties, but on the electrical characteristics as well. The compounds so produced present to the electrical engineer a new type of insulating liquid which eliminates many of the problems heretofore inevitably associated with the use of mineral oil. It is the object of this paper to demonstrate the dielectric strength characteristics of such synthetic liquids both alone and in combination with cellulosic insulation.
