Abstract
A power transformer comprising a transformer core wound with a high-voltage cable (111), wherein the cable comprises an electrically conducting core surrounded by an inner semiconducting layer (113), an insulating layer (114) surrounding the inner semiconducting layer (113) and consisting of solid material, and an outer semiconducting layer (115) surrounding the insulating layer, said layers (113, 114, 115) being adhered to each other and that the winding is provided with spacers (3) arranged to separate each cable turn in axial direction in the winding in order to create disc-shaped cooling ducts, said winding being provided with at least one fan (7) arranged to either force or suck air through all turns of the winding perpendicularly to the leg (2) of the transformer core.
