Fully transposed high tc composite superconductor, method for producing the same and its use

摘要

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.
