    摘要： A power transformer comprising at least one high voltage winding (32) and one low voltage winding (30). Each of the windings includes at least one current-carrying conductor, a first layer having semi-conducting properties provided around said conductor, a solid insulating layer provided around said first layer, and a second layer having semi-conducting properties provided around said insulating layer. The windings are intermixed such that turns of the high voltage winding are mixed with turns of the low voltage winding.

    摘要： An induction controlled voltage regulator, primarily for high voltage regulation, includes a magnetic circuit based upon a metallic core (1) having two or more flux paths or legs (2) with at least one main winding (3) supplying the output voltage (U). Furthermore the voltage regulator includes at least one magnetizable regulation leg (4) with a zone (5) of reduced permeability. The regulation leg is surrounded by a regulation winding (6) connected to a variable capacitor (8). At least one of said windings, or a part thereof, is wound by a high voltage cable comprising at least one current-carrying conductor surrounded by at least a first layer having semiconducting properties, a solid insulating layer and a second layer having semiconducting properties.

    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： A power current booster transformer is wound with a flexible cable (10) comprising inner (12) and outer coaxial (18) conductors separated by an insulating layer (16), one of said conductors forming a primary of the transformer and the other of said conductors forming a secondary of the transformer. Two such flexible cables may provide three windings, two of which are formed by the two inner conductors and the third by the outer conductors connected in parallel.
