    摘要： In order to provide a flexible oxide superconducting cable which is reduced in AC loss, tape-shaped superconducting wires covered with a stabilizing metal are wound on a flexible former. The superconducting wires are preferably laid on the former at a bending strain of not more than 0.2%. In laying on the former, a number of tape-shaped superconducting wires are laid on a core member in a side-by-side manner, to form a first layer. A prescribed number of tape-shaped superconducting wires are laid on top of the first layer in a side-by-side manner, to form a second layer. The former may be made of a metal, plastic, reinforced plastic, polymer, or a composite and provides flexibility to the superconducting wires and the cable formed therewith.

    摘要： An a.c. cable has at least one cable core (15) with two concentric conductor arrangements (8, 9) used as forward and return conductors. At least one of the conductor arrangements (8, 9) contains a plurality of conductor layers (L.sub.j and L.sub.j ') made of stranded normally conducting or superconducting individual conductors (3). The individual conductors preferably feature high-T.sub.c superconducting materials. The wire angles (.alpha..sub.j, .alpha..sub.j ') in the individual conductor layers (L.sub.j and L.sub.j ') should be selected so as to minimize losses. A calculation formula for the wire angles (.alpha..sub.j, .alpha..sub.j ') is given for this purpose.
