Abstract

An electrical structure e.g. an electric cable, comprises a metal body to receive high voltages and insulated with oil impregnated synthetic paper in which the insulating oil has a dielectric loss factor of 0.5 . 10<-3> or less and is constituted by an organic compound containing at least carbon atoms and fluorine atoms. The oil can also contain oxygen atoms. Trifluoromethyl-perfluorodecalin, perfluorodecalin, perfluorotoluene, perfluoro- 1-3 dimethylcicloesane and perfluorinated polyether having a molecular weight between 200 and 5000 are particularly suitable. With such oils, the synthetic paper does not swell excessively.
