Abstract

The power transformer-inductor comprises at least one winding (221,222) in most cases arranged around a magnetizable core (20). The windings are composed of a high voltage cable with solid insulation. The cable has a least one centrally situated electric conductor, and around the conductor there is arranged a first semiconductor layer, around the first semiconductor layer there is arranged an insulating layer around which there is arranged a second semiconductor layer. The second semiconductor layer is earthed at or in the vicinity of both ends (261,262,281,282) of each winding. Furthermore, one point between both ends is directly earthed. Preferably, n points (n\-2) per at least one turn of at least one winding are directly earthed in such a way that the electric connections between the n earthing points divide the magnetic flux into n parts to limit losses produced by earthing.
