Abstract
An electrical capacitor in which metallized foils are loosely disposed one on top of the other and in which the dielectric layer is formed of materials which have desirable electrical properties but which are not particularly adapted to regeneration having a metallized surface which is insulated against the moisture by a liquid insulating oil. The insulating oil layer may consist of polyisobutylene or a silicone oil. A solvent is used to apply the oil and the solvent is given the opportunity to evaporate after the application.
