Patent ID: 8309495

Claim:
Method for production of a superconducting electrical conductor, which has a ceramic material as the superconducting material, said method comprising the steps of: shaping a metal ribbon around a perimeter of a multiplicity of flat strips, each of said flat strips being coated with the superconducting ceramic material, wherein said shaping step includes running said metal ribbon longitudinally to form a tube around said flat strips such that said tube has a slot which runs in the longitudinal direction; with edges of said tube at said slot resting on one another, welding said edges to one another; and reducing the diameter of said tube, which is closed by the welding process, to a diameter which corresponds approximately to the size of the perimeter of the flat strips which are located in the tube such that said tube substantially contacts said flat strips and wherein said reduced diameter presses substantially all of said flat strips so as to be electrically connected with one another.
