Abstract: A cryogenic electric conductor formed from a plurality of superconducting wires arranged in a twisted configuration. The conductor is enclosed in a vacuumtight sheath and the gaps between conductor and the sheath and between the individual wires are filled with a low-temperature cooling medium, preferably helium. Each of the wires has one or more superconducting cores surrounded by a metal e.g. copper, in efficient heat-conducting contact therewith. The sheaths may be formed of a low-conducting metal or from a plastic.
