Electrical winding for a transformer, a choke coil or the like

Claim 1

An electrical winding having a conductor which is radially subdivided into 1 through n subconductor tapes, and wherein within the winding said subconductor tapes are twisted in such a manner that the tape initially lying innermost, after twisting, comes to lie outermost, the tape lying at the second innermost position, after twisting, comes to lie at the second outermost position, etc., wherein the improvement comprises that the subconductor tapes 1 through (n-1) are formed of two partially overlapping tape sections which in the overlap region are conductively connected together at the side edges of the tape sections; that the n th subconductor tape is made of one piece and forms one of the outwardly disposed subconductor tapes of the conductor; that the subconductor tapes 2 through n are laced through between the overlapping tape sections of the first subconductor tape; that the conductor tapes 3 through n are laced through between the overlapping tape sections of the second subconductor, the n th tape being laced through the overlapping tape sections of the (n-1) th conductor, each of the first through (n-1) th conductor tapes being produced from a double width tape wherein two regions are formed by severing half the tape width, the conductor tape extending in said region being offset with respect to itself by one tape width and said regions overlapping in part, one tape region being folded about the side edge of the tape by 180° in the overlap region.
