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.
Claims17
A fully transposed composite superconductor having an at least approximately rectangular cross section, comprising:
- a plurality of conductor elements, combined in the form of a transposed conductor, each including,
- an at least approximately rectangular cross section with a width,
- at least one conductor core composed of a high Tc superconductor material in at least one of a matrix and sheath composed of normally conductive material,
- with respect to lateral bending in the plane of the width, a predetermined bending radius and a predetermined bending zone length, wherein, for each of the conductor elements,
- the bending radius is greater than 100 times the width, and
- the bending zone length is greater than 20 times the width, and
- the conductor elements are fixed to one another.
