摘要： A power transformer or inductor is disclosed. The winding (31) of the transformer/inductor is made of a flexible conductor (38) having electric field containing means forcing the electric field due to the electric current in the winding (31) to be contained within the insulating layer of the flexible conductor (38). The thickness of the insulating layer of the flexible conductor (38) is adopted in such a way to make the electric stress (33) constant throughout the length of the winding. The cross section area of the insulating layer of the flexible conductor (38) is thus optimized, providing for a transformer/inductor design with a high space factor.

摘要： A power- or regulating transformer (11) with voltage regulating means is disclosed. The transformer comprises regulating windings (15) made of a flexible conductor having electric field containing means forcing the electric field due to the electric current int the winding to be contained within the flexible conductor. Since virtually no electric field is to be found outside the flexible conductor of the regulating winding (15), the regulating winding may be formed without having to consider the electric field distribution, thus providing for a transformer with a favorable regulating winding design.

摘要： The present invention relates to a power transformer/reactor (100) comprising at least one winding (221, 222). The winding/windings (221, 222) comprises/comprise at least one electric conductor, a first semiconducting layer (14) arranged around the conductor, an insulating layer (16) arranged around the first semiconducting layer (14), and a second semiconducting layer (18) arranged around the insulating layer (16). The winding/windings (221, 222) is/are enclosed in a container (102) filled with a liquid, said liquid accomplishing a cooling.
