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 of manufacturing a capacitive electrical device is disclosed. The method includes a) bonding a first electrical insulation film with a second electrical insulation film to obtain a single electrical insulation film that has a larger surface area than any of the first electrical insulation film and the second electrical insulation film has alone, b) providing a conductive layer onto the single electrical insulation film, and c) winding the single electrical insulation film and the conductive layer around a shaft to obtain a layer of the single electrical insulation film and a layer of the conductive layer wound onto the shaft, thereby forming the capacitive electrical device.

Abstract: An electrical bushing including an electrically insulating shell having a central longitudinal through hole and a first longitudinal end configured to be at a top of the bushing and a second longitudinal end configured to be at a bottom of the bushing. The bushing is configured for accommodating an electrical conductor positioned through the central longitudinal through hole of the shell. The shell includes fastening means for fastening the bushing to a wall of an electrical apparatus, through which wall the bushing is configured for allowing the electrical conductor to pass. The shell is configured for sealingly containing an electrically insulating liquid in the bushing, allowing the bushing to be liquid-filled. The shell is molded as a single piece from an electrically insulating polymeric material.

Abstract: An electrical power component, such as a bushing. The power component includes a housing, a condenser core arranged in the housing and including an electrical insulation, a space formed between the condenser core and the housing, an expansion vessel positioned adjacent and in open communication with the space between the condenser core and the housing, and an electrically insulating fluid, such as oil, contained in the space between the condenser core and the. The power component further includes one or more filler elements having a higher density and lower thermal expansion coefficient than the fluid, and the one or more filler elements are movably arranged in the expansion vessel.
