The present disclosure relates to an air-to-air through-wall bushing including a conductor, insulation surrounding the conductor, a ventilation inlet at a first end of the bushing, and a ventilation outlet at a second end of the bushing. The bushing is arranged through a wall and a pressure difference between a first pressure on a first side of the wall and a second pressure on a second side of the wall is provided The inlet and outlet allow cooling air to pass through a ventilation channel within the bushing driven by the provided pressure difference.

Air-cooled air-to-air bushing

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.

Electrical bushing

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.
