Abstract: A high voltage capacitive device having: a non-impregnatable film having a plurality of physically separated regions each defined by a conductive coating provided on the non-impregnatable film, wherein the non-impregnatable film is wound in a plurality of turns to form a plurality of layers, wherein the regions are arranged in overlapping layers in the radial direction, wherein the non-impregnatable film forms a dielectric between adjacent layers of the regions, and wherein the conductive coating of at least some of the regions is provided with a plurality of first radial openings extending through the conductive coating to the non-impregnatable film, which delimits a radial extension of each first radial opening.

Abstract: A method for producing an electrical power device having an insulator. The method includes, by means of additive manufacturing, applying a polymeric insulating material forming part of the device. The method also includes, in a subsequent consolidation step, subjecting the insulator to elevated temperature and pressure during a predetermined time period to consolidate the insulator.
