Abstract: A winding body for a superconductive secondary winding for a superconductive current-limiting transformer includes a plurality of depressions and casing portions distributed around a circumference in the longitudinal direction; and grooves in the casing portions in the circumferential direction. The winding body is configured such that a superconductive conductor of the secondary winding can be wound around the winding body in a normal state such that the conductor rests against the casing portions and is received in the grooves. A gap can be formed between the conductor and each of the depressions.

Abstract: A conductor assembly and method for constructing an assembly of the type which, when conducting current, generates a magnetic field or which, in the presence of a changing magnetic field, induces a voltage. In one embodiment the method provides a first insulative layer tubular in shape and including a surface along which a conductor segment may be positioned. A channel formed in the surface of the insulative layer defines a first conductor path and includes a surface of first contour in cross section along a first plane transverse to the conductor path. A segment of conductor having a surface of second contour in cross section is positioned at least partly in the channel and extends along the conductor path. Along the first plane, contact between the conductor surface of second contour and the channel surface of first contour includes at least two separate regions of contact.
