发明名称 Power transformer/inductor
摘要 The present invention relates to a power transformer/inductor comprising at least one winding. The windings are designed by means of a high-voltage cable, comprising an electric conductor, and around the conductor there is arranged a first semiconducting layer, around the first semiconducting layer there is arranged an insulating layer and around the insulating layer there is arranged a second semiconducting layer. The second semiconducting layer is earthed at or in the vicinity of both ends ( 26 <SUB>1</SUB> , 26 <SUB>2</SUB> ; 28 <SUB>1</SUB> , 28 <SUB>2</SUB>) of each winding and furthermore one point between both ends ( 26 <SUB>1</SUB> , 26 <SUB>2</SUB> ; 28 <SUB>1</SUB> , 28 <SUB>2</SUB>) is directly earthed.
