Abstract: An on-load tap-changer for dry transformers, having an electric insulating hollow casing extending around a virtual axis, wherein several electric contact sections are foreseen along a path on the inner surface of the hollow casing, which are electrically joined through the wall of the hollow casing and a selector contact in the inner of the cylinder which is moveable along the path and that's outer end is selectively connectable with one of the contact sections by a respective movement. Respective cables are foreseen to electrically connect the contact sections from the radial outer side of the hollow casing, wherein at least some of the cables have a respective surrounding outer insulation at least at their respective connected end.

Abstract: A vehicle transformer has a transformer core with two opposed yokes and at least two limbs extending in between them along a parallel limb axis, wherein a support structure is provided at each of the yokes for carrying the vehicle transformer with horizontal oriented limb axis, wherein a hollow cylindrical coil with at least one respective electrical winding is arranged around at least one of the limbs. The coil may be rigidly connected with the limb so that the flexural resistance of the rigid combination of both is improved therewith compared to a combination of both without rigid connection.

Abstract: A dry transformer load switch, and transformer having such switch, has a hollow insulation cylinder extending longitudinally about a virtual center axis and has a plurality of connection contacts arranged along the inner circumference thereof, and a radially oriented main contact arranged in the interior of the hollow insulation cylinder so as to be rotatable about the center axis and which, with a corresponding rotary movement, can be optionally electrically connected by the radially outer end thereof to one of the connection contacts. In a hollow-cylindrical space about the center axis that is defined by the radially inner and outer end of the main contact, there is a barrier shield, which can be rotated together with the main contact about the axis.
