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.
