Abstract
Liquid, non-flammable dielectric compositions especially adapted as insulators/coolants for transformers are comprised of [1] a mixture of polychlorobenzenes, including a major amount of an at least trichlorinated benzene and a minor amount of ortho-dichlorobenzene, and [2] an alkylaromatic hydrocarbon or a partially hydrogenated bi- or terphenyl.
