Abstract
A method for manufacturing an electric winding of an electromagnetic induction apparatus includes providing a conductor structure and forming an electric winding by means of the conductor structure. The conductor structure includes a conductor element extending longitudinally along a main extension direction and one or more spacer bands arranged on corresponding lateral surfaces of the conductor element. Each spacer band includes a supporting structure made of electrically insulating material and spacer elements made of electrically insulating material arranged on the supporting structure. The spacer elements are spaced one from another along the supporting structure. The electric winding extends axially along a winding direction and has a plurality of turns arranged around the winding direction. Each turn of the electric winding is formed by a corresponding longitudinal portion of the conductor element. The spacer elements are interposed between adjacent turns of the electric winding at opposite sides of the turns.
