Abstract

The invention relates to an electrical winding for a transformer, a choke coil or the like, particularly for high frequencies, wherein the conductor forming the winding is radially subdivided into n subconductors and within the winding the subconductors are twisted in such a manner that the initially innermost subconductor, after twisting comes to lie outermost, the subconductor in the second innermost position, after twisting comes to lie at the second outermost position, etc. If the subconductors are designed as conductor tapes, the subconductors 1 through (n-1) comprise two partially overlapping tape sections which in the overlap region are conductively connected together at the side edges of the tape, the n.sup.th conductor tape being made of one piece and forming one of the outwardly disposed subconductors of the conductor. The conductor tapes 2 through n are laced through between the overlapping tape sections of the first subconductor, the conductor tapes 3 through n are laced through between the overlapping tape sections of the second subconductor, the n.sup.th tape being laced through between the overlapping tape sections of the (n-1).sup.th conductor.
