Abstract: A high voltage winding for a single electrical phase of a high voltage electromagnetic induction device, wherein the high voltage winding comprises: a first winding part, and a second winding part, wherein the first winding part comprises: a first conductor, a first solid electrical insulator circumferentially enclosing the first conductor, and a first semi-conductive sheath circumferentially enclosing the first solid electrical insulator, wherein the first semi-conductive sheath is earthed or connected to an electric potential that is lower than a rated voltage of the high voltage winding, and wherein the second winding part comprises: a second conductor, and a second solid electrical insulator circumferentially enclosing the second conductor and forming an outermost layer of the second winding part.

Abstract: A method of manufacturing a polymer-insulated conductor. The method includes the steps of a) providing a conductor having a first cross-sectional shape, b) passing the conductor through a conductor-shaping die to shape the conductor such that the conductor obtains a second cross-sectional shape, wherein frictional heat is developed in the conductor, thereby setting the conductor in a heated state, c) applying molten polymer to the conductor when the conductor is in the heated state to obtain a polymer-coated conductor, and d) shaping the polymer-coated conductor by means of a polymer-shaping die to thereby obtain the polymer-insulated conductor.
