A power transformer/reactor (1) wound with high voltage cable (111) and provided with both an outer semiconducting layer (115) and spacing means in which the spacing means (4, 10, 19, 119) are arranged to separate each winding in the radial direction in order to create coaxial cylindrical cooling ducts (3), whereby at least one spacing means (4, 10, 19, 119) is electrically conducting and provided with a part (17, 21) which is resistant to wear and that the spacing means (4, 10, 19, 119), at least at one of its sides (13), is connected in a partly surrounding way to the outer semiconducting layer (115) of the high voltage cable (111). |
