Abstract
A power transformer includes at least one winding formed from at least one conductor extending along a circumferential direction, wherein the at least one winding has a tap in a contact section formed by a profile of the at least one conductor in at least one direction inclined relative to the circumferential direction; and at least one supporting element configured to support the conductor in the contact section.

1-16. (canceled)
A power transformer comprises:
- at least one winding formed from at least one conductor extending along a circumferential direction, wherein the at least one winding has a tap in a contact section formed by a profile of the at least one conductor in at least one direction inclined relative to the circumferential direction;
- and
- at least one supporting element configured to support the conductor in the contact section.
A method for production of an electrical power transformer comprising:
- providing a conductor;
- winding the conductor along a circumferential direction around a rotation axis corresponding to an axis of symmetry of the electrical power transformer;
- guiding the conductor in a direction inclined with respect to the circumferential direction so as to add a tap;
- and
- adding a supporting element for the tap so as to form a mechanical contact between the supporting element and the conductor.
