Abstract
A method is provided for producing a superconductive electrical conductor, in which a layer of an yttrium-barium-copper oxide (YBCO) is applied as a superconductive material onto a textured metal substrate, and is subjected to a heat treatment. In order to produce a wire-shaped conductor, a textured metal substrate, provided as a strip (), is initially shaped in its longitudinal direction around an elongate metal support () with a circular cross section to form a slotted tube () having edges extending in the longitudinal direction and adjoining one another at a slot (). The slotted tube () is next closed by welding the slot () shut, and the closed tube () is then contracted by pulling until it bears on the support (). The layer () of superconductive YBCO material is thereupon applied all around, and the heat treatment is finally carried out.
