Abstract
A power transformer (1) provided with a transformer core, whereby the core is wound with a high voltage cable (111) which is flexible and composed of an electrically conducting core surrounded by an inner semiconducting layer (113), an insulating layer (114) of solid material surrounding the inner semiconducting layer (113), and an outer semiconducting layer (115) surrounding the insulating layer (114), said layers (113, 114, 115) being adhered to each other and that 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).
