Abstract
A conductor and a rotating electric high-voltage machine that includes the conductor has a cable configured for high-voltage operation. The cable may be included as a winding for the rotating electric high-voltage machine. The conductor includes a first strand that is clad with an electrically insulating layer, and a second strand that is uninsulated whereas the first strand and the second strand are arranged in two or more layers of strands. The two or more layers of strands are insulated from one another. Furthermore, the first and second layers of the two or more layers of strands are arranged around a central core where the central core is at least one of an air core and a core of another material. The second strand is positioned so as not to be electrically contacting any other uninsulated strand.
