A power transformer (1) is provided with a transformer core which is wound with a high voltage cable (111). This cable is flexible and composed of an electrically conducting core surrounded by an inner semiconductor layer, an insulating layer of solid material surrounding the inner semiconductor layer and an outer semiconducting layer surrounding the insulating layer. The three layers comprising the high voltage cable are adhered to each other. The winding (2) is provided with spacers (4) which are arranged to separate each cable turn in the axial direction in order to create disk formed cooling ducts (3). |
