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.
