Abstract
In order to provide a flexible oxide superconducting cable conductor which is reduced in ac loss, tape-shaped multifilamentary superconducting wires covered with a stabilizing metal are spirally wound on a flexible former. Each of the multifilamentary superconducting wires has a plurality of filaments. The filament contains an oxide superconductor. The superconducting wires are preferably wound on the former at a bending strain of not more than 0.3 %. In winding on the former, a prescribed number of tape-shaped multifilamentary superconducting wires are wound on a core member in a side-by-side manner, to form a first layer. Then, an insulating layer is provided on the first layer. This insulating layer can be formed by an insulating tape. A prescribed number of tape-shaped superconducting multifilamentary wires are wound on the insulating layer in a side-by-side manner, to form a second layer. The insulating layer is adapted to reduce ac loss of the conductors. When the former is made of a metal, it is more preferable to provide an insulating layer between the former and the multifilamentary superconducting wires.
