Abstract

A superconductive conductor and method of using the superconductive conductor is described. The superconductive conductor includes a plurality of first conductive strips with a first width and a plurality of second conductive strips with a second width, and a strip stack formed from the first and second conductive strips that has a cruciform-shaped cross section.

First claim

The invention claimed is:

1. A superconductive conductor, comprising:
a plurality of first conductive strips, each having a first width;
a plurality of second conductive strips, each having a second width; and
one or more fittings adjacent the plurality of second conductive strips,
wherein the first width differs from the second width,
wherein the plurality of first conductive strips and/or the plurality of second conductive strips comprises a plurality of superconductive strips,
wherein the plurality of first conductive strips and the plurality of second conductive strips are arranged into a strip stack with a cruciform-shaped cross section,
wherein in each case two conductive strips successively arranged in the strip stack are soldered to each other to form a superconductive body,
wherein the first width is greater than the second width,
wherein the plurality of first conductive strips and the plurality of second conductive strips arranged in a same direction,
wherein the strip stack comprises a first end, a second end, and a middle section, and
wherein the first and second ends are formed by respective ones of the plurality of second conductive strips, and the middle section is formed by the plurality of first conductive strips and has a height that corresponds to the second width, and
wherein a ratio of the second width to the first width is between 0.6 and 0.7.

2. The superconductive conductor according to claim 1 , wherein the strip stack only consists of strips with two different widths.

3. The superconductive conductor according to claim 1 , wherein the strip stack is formed entirely from first conductive strips with the first width and second conductive strips with the second width.

4. The superconductive conductor according to claim 1 , wherein the strip stack comprises a middle section and two end sections, wherein the middle section is arranged directly between the two end sections and wherein the middle section is formed only from first conductive strips and the respective end sections are formed only from second conductive strips.

5. The superconductive conductor according to claim 1 further comprising:
a cladding tube.

6. The superconductive conductor according to claim 1 , wherein the superconductive body has a twisting.

7. A method of using the superconductive conductor according to claim 1 , the method comprising:
forming a cable with the superconductive conductor, the cable being suitable for the transmission of energy and/or for the generation of magnetic fields.

8. The method of claim 7 , wherein the cable comprises a plurality of superconductive conductors.

9. The method of claim 7 , wherein the superconductive conductor is heated locally to form a bent cable.

10. The superconductive conductor according to claim 1 , further comprising:
one or more metal wires.

11. The superconductive conductor according to claim 1 , further comprising:
one or more steel wires.

12. The superconductive conductor according to claim 1 , further comprising:
insulating material.

13. The method of claim 8 , wherein the cable comprises one or more twisted combinations of the plurality of superconductive conductors.

14. The method of claim 9 , wherein the superconductive conductor is heated to or above a melting temperature of the soldering agent used in the superconductive conductor.
