Abstract: A method involves sheathing a superconductor with a thermoplastic insulation material on all sides. The conductor exits a guide channel that extends in the propulsion direction. A melt hose is extruded from the molten insulation material in the propulsion direction and through a nozzle that has an outlet which embraces the conductor, whereby a distance is kept on all sides. The melt hose is stretched via the propulsion of the conductor. The hose is drawn to the surface of the conductor and is compacted by cooling. The method can especially be used for sheathing band-shaped high-Tc-superconductors. Materials having processing temperatures between 200° C. and 450° C., are selected as thermoplastic insulation materials.

Abstract: A fully transposed composite superconductor can be especially used for AD devices and contains subconductors composed according to the Roebel bar principle and containing TC superconducting material. Superconductors are provided, that can be laterally bent in the plain of their width B so that the bending radius R is more than 100 times the width B and the bending zone length Hsue et al. '352 publication is more than 20 times the width B. The device for producing the conductor includes devices disposed in series for combining, bending, assembling to a Roebel bar, and fixating the subcontractors.

Abstract: The invention relates to a fully transposed composite superconductor (2) that can be especially used for AD devices and that contains subconductors (3j) composed according to the Roebel bar principle and containing high Tc superconducting material. The aim of the invention is to provide subconductors, that can be laterally bent in the plane of their width B so that the bending radius R is more than 100 times the width B and the bending zone length H is more than 20 times the width B. The inventive device for producing the conductor (2) comprises means disposed in series for combining, bending, assembling to a Roebel bar, and fixating the subconductors.
