Abstract: The method relates to an electric device comprising at least two electrodes which are separated by dielectric part. At least one of said electrodes is arranged to be at a floating potential. The dielectric part comprises at least one turn of at least one non-impregnatable electrically insulating film between two neighboring electrodes. The electrodes are bonded to adjacent turns of non-impregnatable insulating film, and adjacent turns of non-impregnatable insulating film, if any, are bonded to each other, so that the turns of non-impregnatable insulating film and the electrodes form a solid body. The invention further relates to a method of manufacturing an electric device, where bonding of at least one turn is performed upon forming of said turn, so that the bonding of said turn to the turn/electrode underneath will commence before said turn has been completely covered by the next turn.

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.
