Abstract
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.
