Abstract

An insulated high-temperature wire superconductor includes a wire of a non-insulated high-temperature wire superconductor, the width of which is at least 10 times its thickness and in which a high-temperature superconductor is introduced into a matrix or is applied to a substrate. The wire is provided with an electrically non-conducting insulating layer on both sides such that the two insulating layers have an insulating edge width in a range from 2 mm to 200 mm which projects in relation to the wire.

First claim

The invention claimed is:

1. An insulated high-temperature wire superconductor, comprising:
a wire of a non-insulated high-temperature wire superconductor, the width of which is at least 10 times its thickness and in which a high-temperature superconductor is disposed in a matrix or is on a substrate, the wire being provided with an electrically non-conducting insulating layer on both sides such that the two insulating layers have an insulating edge width in a range from 2 mm to 200 mm which projects in relation to the wire.

2. The insulated high-temperature wire superconductor according to claim 1 , wherein the two insulating layers have a common thickness of 20 μm to 2 mm.

3. The insulated high-temperature wire superconductor according to claim 1 , wherein at least one of the two insulating layers is laminated on one side of the wire.

4. The insulated high-temperature wire superconductor according to claim 3 , wherein at least one of the two insulating layers is laminated with a layer of an adhesive on the side facing the wire.

5. The insulated high-temperature wire superconductor according to claim 1 , wherein, at least one of the two insulating layers consists of at least one polymer.

6. The insulated high-temperature wire superconductor according to claim 5 , wherein at least one of the two insulating layers consists of polyimide.

7. A method for producing the insulated high-temperature wire superconductor according to claim 1 , the method comprising:
applying the electrically non-conducting insulating layer to each of both sides of the wire of the non-insulated high-temperature wire superconductor, the width of the wire being at least 10 times its thickness, and where the high-temperature superconductor is introduced into the matrix or applied to the substrate, such that the two insulating layers have the insulation edge width in the range from 2 mm to 200 mm projecting in relation to the wire.

8. The method according to claim 7 , the thickness of the insulating layers being selected such that the common thickness is from 20 μm to 2 mm.

9. The method according to claim 7 , wherein at least one of the two insulating layers is laminated to a side of the wire.

10. The method according to claim 9 , wherein the lamination is performed with a hot adhesive or heat seal adhesive at a reaction temperature in a range from 100° C. to 250° C., for which purpose a side of the at least one insulating layer facing the wire is laminated with the hot adhesive or hot seal adhesive.

11. The method according to claim 7 , wherein a film of at least one polymer is used as an insulating layer.

12. The method according to claim 11 , wherein a film of polyimide is used as the insulating layer.
