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.
