摘要： The present invention relates to an electrical power transmission system using superconductors which is compatible with conventional transmission systems. In a first aspect, a method for installing in an electrical power transmission system a connection using a coaxial superconducting cable, includes determining a reactance of a conventional cable suitable for the connection; installing the coaxial superconducting cable, and increasing a reactance of the coaxial superconducting cable, in such a way that the reactance of the superconducting cable is substantially equal to the reactance of the conventional cable. In particular, increasing the reactance of the coaxial superconducting cable includes connecting in series with the coaxial superconducting cable an inductive element, preferably made from a superconducting material.

摘要： A superconducting cable for high power with at least one phase includes a superconducting core wherein a plurality of elements are housed, which are structurally independent and magnetically uncoupled, each of which includes—for each phase—a couple of phase and neutral coaxial conductors, each formed by at least a layer of superconducting material, electrically insulated from one another by interposition of a dielectric material. As a result of the distribution of the superconducting material into several coaxial conductive elements, the cable allows to transmit high current amounts in conditions of superconductivity, while using a high-temperature superconducting material sensitive to the magnetic field. The conductive elements are connected at the ends to yield a mean exploitation efficiency of 100%.
