An electrical power transmission line having at least one electrical cable, a conduit of ferromagnetic material enclosing the electrical cable and having a base and a cover and electrical contact elements for electrically connecting the base and the cover, wherein the electrical contact elements are metal fusion joints or metal resilient members suitable to pierce the ferromagnetic material.

Method of screening the magnetic field generated by an electrical power transmission line and electrical power transmission line so screened

A method of terminating at least one conductor of a superconducting cable comprising a plurality of superconducting tapes, comprising the steps of associating an electrically conductive connector radially at the at least one conductor, embedding and end of the superconducting tapes in a thermosetting resin, embedding an end portion of the superconducting tapes in a solder and achieving an electric contact by the solder. Moreover, the invention relates to a terminated conductor of a superconducting cable, a superconducting cable, a joint between conductors of two superconducting cables, a current transmission/distribution network, and a terminator for at least one conductor of a superconducting cable that embody the above method.

Method for terminating a conductor of a superconducting cable

A superconducting cable comprising at least a superconducting conductor and a cryostat, including a thermal insulation and an inner tube, with a protecting element between the superconducting conductor and the inner tube, to prevent damages to the superconducting material by the inner tube of the cryostat.

Superconducting cable

A superconducting cable includes at least one layer of tapes of superconducting material circumferentially wound side by side on a support at a prefixed distance forming gaps circumferentially among adjacent tapes. Within the superconducting cable, a non-superconducting material is interposed between adjacent tapes to partially fill the gaps.

The invention features a superconducting conductor for use in a preselected fluid cryogen including a composite ceramic superconducting wire having an outer surface along its length; and a sealing structure hermetically surrounding the outer surface to prevent the cryogen from infiltrating into the wire and degrading its superconducting properties, even under pressurized conditions. The superconducting conductor can be used in superconducting cabling and coil applications. The sealing structure can be formed by laminating metallic tapes to the wire, encircling at least one metallic sheet around the outer surface of the wire, welding a plurality of metallic sheets to one another to encircle the outer surface of the wire, or forming a polymer coating completely covering the outer surface of the wire.

Encapsulated ceramic superconductors

A method for joining high temperature superconducting components while minimizing critical current degradation is provided. The articles formed have critical currents that are at least 80 % of the critical current of the high temperature superconducting components. The invention further provides splicing geometries that facilitate wrapping joined components around a mandrel, tube or the like with minimal critical current degradation and without kinking or flexion of the joined components.
