Abstract
1441803 Dielectric fluids GENERAL ELECTRIC CO 24 July 1973 [16 Aug 1972 12 bune 1973 (2)] 35315/73 Heading C5F [Also in Division H1] An insulating liquid composition for impregnating a wound capacitor having paper, plastics or both as dielectric comprises a liquid aromatic ester having an epoxide additive. The ester may be a phthalate, particularly dioctyl phthalate, a benzoate, a phosphate, e.g. tricresyl phosphate, mixtures of these with each other or with other insulating liquids, e.g. dibutyl sebacate, castor oil, mineral oil, alkyl naphthalenes, polybutenes and dodecylbenzene. The epoxide may constitute 0À01 to 10% by weight of the impregnant, or even more where it can itself function as an impregnant.
