Abstract
A superconducting cable containing a plurality of individual wires which are stranded or plaited to wire bundles and ropes, wherein in order to avoid relative movement and/or deformation between the wire bundles and/or ropes as, for example, may otherwise be caused by high current loading, the individual wire bundles and the ropes are materially joined together at their points of contact, preferably by soldering, to form a mechanically rigid structure, in which the parts between the soldered areas can as well as possible deform elastically, thereby avoiding all disadvantages associated with freely movable wire bundles. In a preferred embodiment, the ropes are made from wire bundles arranged in a lattice.
Claims17
A super-conducting cable comprising:
- a plurality of wires combined in groups to form plural wire bundles, said plural wire bundles combined in groups to form plural ropes, and said plural ropes being combined;
- and
- a vacuum tight casing enclosing said plural combined ropes;
- said wires in each of said bundles having plural mutual wire contact sites, said bundles in each of said ropes having plural mutual bundle contact sites, and said ropes enclosed in said casing having plural mutual rope contact sites;
- wherein there is provided a substantially homogeneous metal-to-metal connection at said wire contact sites, said bundle contact sites and said rope contact sites, said wire bundles including a stabilizing material having contact sites connected to wires adjacent thereto by means of a substantially homogeneous metal-to-metal connection at the respective contact sites.
