Abstract

A method is specified for production of a superconducting electrical conductor which has a ceramic material as the superconducting material. A metal ribbon is formed around a multiplicity of flat strips of a mount which is coated with the superconducting ceramic material, running longitudinally to form a tube having a slot which runs in the longitudinal direction, and whose edges which rest on one another on the slot are welded to one another The tube which is closed by the welding process is then reduced to a diameter which corresponds approximately to the envelopes of all the strips which are located in the tube.
