Method and conductor structure for manufacturing an electric winding of an electromagnetic induction apparatus

A conductor structure for manufacturing an electric winding of an electromagnetic induction apparatus, comprising:

• a conductor element extending longitudinally along a main extension direction;
• one or more spacer tapes of electrically insulating material around said conductor element along said main extension direction, each of the one or more spacer tapes having a plurality of spacer portions at corresponding lateral surfaces of said conductor element, said spacer portions being spaced one from another along the lateral surfaces of said conductor element;
• and
• an electrically insulating enclosure surrounding the conductor element and the one or more spacer tapes, the electrically insulating enclosure fixing the one or more spacer tapes to the conductor element,
• wherein said conductor structure is intended to form an electric winding, said electric winding extending axially along a winding direction and having a plurality of turns arranged around said winding direction,
• wherein each turn of said electric winding is formed by a corresponding longitudinal portion of said conductor element, and
• wherein spacer portions of each of the one or more spacer tapes are interposed between adjacent turns of said electric winding at opposite sides of said turns, wherein the spacer portions are respectively positioned spaced one from another to define an empty space to form a radial channel of the electric winding, wherein the radial channel is configured for a passage of an electrically insulating medium.
