Abstract
A multifilamentary superconducting cable has two parallel spaced-apart guide wires. A first layer of mutually parallel superconducting filaments is woven partially around and between the guide wires in a transposed braid. Likewise, a second layer of mutually parallel superconducting filaments is woven partially around and between the guide wires in a transposed braid. Thus, the two layers overlap each other as the respective layers pass between the guide wires. The two superconducting layers and two guide wires are enclosed in a helical copper duct, with the guide wires being oriented within the duct.
