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.

The present disclosure relates to a bushing comprising a conductor tube, a support tube, arranged within the conductor tube, a draw-rod configured to run through the support tube, and a contact arrangement arranged to be drawn into the conductor tube by the draw-rod. The contact arrangement comprises a sealing plug arranged for sealingly engaging an inside wall of the conductor tube to prevent liquid from passing the sealing plug into the conductor tube.

An electrical induction device includes a housing and a contact arrangement in the housing of the electrical induction device for electrically contacting an electrical conductor. The contact arrangement includes a conductor tube, a receiver contact which is fastened to the conductor tube and configured to receive and electrically connect with the electrical conductor, and a resilient suspension arrangement fastened to the housing and connected to an outside of the conductor tube such that the receiver contact is resiliently movable in a plane which is parallel to a cross section of the conductor tube while being substantially immovable in an axial direction of the conductor tube.
