Abstract
An a.c. cable has at least one cable core (2) with a central carrier body (4), having at least three conductor layers (L.sub.j) of normal conductors or superconductors (3) stranded around it. The conductors preferably have high-T.sub.c superconducting material. The wire angles (.alpha..sub.j) in the individual conductor layers (L.sub.j) are selected so that viewed in the radial direction they gradually increase or decrease from layer to layer. The cable core can advantageously have a concentric arrangement of a forward and a return conductor.
