A wall bushing for high voltage application is presented. The wall bushing includes a grounded shield. The grounded shield includes a grading ring in a distal end thereof. The grading ring has an elliptic cross section with conjugate diameters, wherein a major diameter of the conjugate diameters is arranged in an axial direction of the grounded shield and a minor diameter of the conjugate diameters is arranged in a radial direction of the grounded shield. The major diameter is larger than the minor diameter.

Wall bushing

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.
