Abstract
A superconductive electrical cable is provided, which comprises a conductor consisting of superconductive wires. The conductor (L) is designed as a stranded conductor in which the wires (1) are stranded together with a predetermined pitch length (S) lying between about 5×D and about 20×D, where D is the diameter of the stranded conductor.
Claims5
Superconductive electrical cable comprising:
- a conductor having superconductive wires enclosed by a cryostat for guiding a cooling medium that is made of two concentric metal tubes which are separated from one another by an annular space in which vacuum insulation is provided, wherein the conductor is a stranded conductor in which a plurality of wires are in physical contact with each other and are stranded together with predetermined pitch length having a value between about 5×D and about 20×D, where D is the diameter of the stranded conductor, and wherein the conductor is subdivided into sectors by thin insulating layers.
