摘要： In order to provide a flexible oxide superconducting cable which is reduced in AC loss, tape-shaped superconducting wires covered with a stabilizing metal are wound on a flexible former. The superconducting wires are preferably laid on the former at a bending strain of not more than 0.2%. In laying on the former, a number of tape-shaped superconducting wires are laid on a core member in a side-by-side manner, to form a first layer. A prescribed number of tape-shaped superconducting wires are laid on top of the first layer in a side-by-side manner, to form a second layer. The former may be made of a metal, plastic, reinforced plastic, polymer, or a composite and provides flexibility to the superconducting wires and the cable formed therewith.

摘要： A superconducting cable (1) for high power with at least one phase comprises a superconducting core (2) wherein a plurality of elements (3) 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 (8). Thanks to the distribution of the superconducting material into several coaxial conductive elements (3), the cable (1) allows to transmit high current amounts in conditions of superconductivity, while using a high-temperature superconducting material sensitive to the magnetic field.

摘要： A two stage cryocooler sleeve is provided having a second stage heat exchanger system capable of achieving lower temperatures than the first stage heat exchanger. A current lead comprising a ceramic superconductor having a critical temperature greater than the operating temperature of the first stage is tapered. The broader end is thermally coupled to the first stage heat exchanger and the narrow end coupled to the second stage heat exchanger. The tapered ceramic lead reduces the heat conduction from the first heat exchanger to said second heat exchanger.

摘要： A cryogenically stabilized superconductor in cable form comprises several superconducting elements which contain twisted conductor filaments of superconductive material which are embedded in a matrix material of predetermined electric conductivity and which are twisted with several stabilizing elements of thermally and electrically highly conductive material which is electrically normal conducting at the operating temperature of the superconductor and the electric conductivity of which at the operating temperature is substantially higher than that of the matrix material of the superconducting elements disposed parallel thereto. So this superconductor will be capable of carrying large currents, will have high cryogenic stability and at the same time have only small alternating field losses, pairs of stabilizing elements and superconducting elements form respective stabilized subconductors, the stabilizing elements of which are connected in an electrically conducting manner only at individual points disposed one behind the other in the lengthwise direction of the conductor to the respective superconducting elements; and the subconductors are twisted together and are electrically insulated from each other in such a manner that an electrically highly conducting cross connection of all subconductors is provided only after one or more respective twisting lay lengths.

摘要： A coaxial electric power transmission cable has an inner conductor within an outer conductor with solid dielectric material provided in the space therebetween. The dielectric material is solid at operating temperatures but non-solid at ambient temperature. An insulative spacer is provided for maintaining the coaxial alignment. The spacer includes insulative material which is identical to the solid dielectric material and may include a solid insulative insert having a solidification point higher than the insulative material whereby at least approximate coaxial spacing may be maintained should the insulative material not be maintained as a solid.

摘要： The spacer is helically wound on the inner one of two concentric tubes, and is constructed from plural elongated, generally flat members of different cross-section and profile for surface contours permitting only limited contact between adjacent members. Alternation between convex and concave surfaces prevents lateral shifting of the members off each other.
