A capacitor element is made by interwinding electrode foils and non-porous dielectric films, without interposed paper wicks. The foils and films are wound at different tensions so that transverse passages are formed between adjacent surfaces within the element; when the element is subsequently impregnated with dielectric liquid, those passages facilitate entry of the liquid between the various foils and films and assist proper permeation. The dielectric film and dielectric liquid are preferably polypropylene and mineral oil respectively. |
