摘要： A superconducting cable includes a cryogenic fluid, a superconducting conductor, and a cryostat. A layer impervious to the cryogenic fluid is provided between the superconducting conductor and the cryogenic fluid. The superconducting conductor operates in a space substantially free from fluids liquefying at a temperature greater than or equal to an operative temperature of the superconducting cable. A method for protecting a superconducting cable from formation of balloons includes isolating the superconducting conductor from the cryogenic fluid using a layer impervious to the cryogenic fluid and operating the superconducting conductor in a space substantially free from fluids liquefying at a temperature greater than or equal to an operative temperature of the superconducting cable. A current transmission/distribution network including at least one of the superconducting cables is also disclosed.

摘要： 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.

摘要： A process for producing a multifilamentary conductive tape of the type including a plurality of layers of a high-temperature superconducting material, incorporated in a mutually spaced relationship within a metal matrix, includes the steps of: a) submitting to plastic deformation individual metal tubes including a precursor of a superconducting material, so as to obtain a plurality of elementary tapes structurally independent from one another; b) coupling the tapes so obtained by means of a heat treatment at a temperature and for a time sufficient to establish a stable mutual connection between said tapes. The multifilamentary tape so obtained or possibly the independent tapes, are then subjected to at least one sintering step, which may be followed by one or more cycles of plastic deformation and sintering. Advantageously, the process of the invention allows to increase the fill factor of the tape, with a corresponding increase in the critical current in superconductivity conditions.
