A high-tension capacitor including alternating dielectric layers and electrode layers, the dielectric layers having a synthetic resin film between a layer of highly impregnable and porous material. The capacitor elements having the alternating electrode layers and dielectric layers are surrounded by a highly impregnable electrically insulating material and the assembly is impregnated with a synthetic resin which penetrates the porous layers of the dielectric layers and the insulating material surrounding the capacitor elements. Alternatively, the capacitor elements are impregnated with a resin having a good impregnability and low viscosity and the insulation layer molded around the impregnated capacitor elements can be impregnated with a resin having good strength and high viscosity. A relaxation layer may also be interposed at regular intervals between the electrode layers and dielectric layers for absorbing the shrinking force upon hardening of the synthetic resin. |
