Abstract
Abstract Described is a fully or partly stabilized conductor combined of superconducting and normal-conducting metals. The conductor is characterized in that several superconductors with small cross section are combined with a copper matrix to form a multicore conductor. The superconductors are completely embedded in the copper matrix and in metallurgical connection therewith. Several multiconductors are enclosed with one aluminum jacket and are electrically and thermally connected with the same.
