<p>The present invention relates to a rotating electric high voltage machine comprising a stator (8), a rotor (7; 37; 47) and at least one winding. The machine is characterized in that said winding comprises at least one current-carrying conductor (2), that a first layer (3) having semiconducting properties is provided around said conductor, that a solid insulating layer (4) is provided around said first layer, and that a second layer (5) having semiconducting properties is provided around said insulating layer. Alternatively, the rotating electric machine according to the invention is provided with a magnetic circuit for high voltage comprising a magnetic core and a winding, and is characterized in that said winding is formed of a cable (1; 11) comprising at least one current-carrying conductor (2), that each conductor comprises a number of strands (18), that an inner semiconducting layer (3) is provided around each conductor, that an insulating layer (4) of solid insulating material is provided around said inner semiconducting layer, and that an outer semiconducting layer (5) is provided around said insulating layer.</p> |
