Abstract: A method of manufacturing an elongated electrically conducting element having functionalized carbon nanotubes and at least one metal, includes the steps of mixing functionalized carbon nanotubes with at least one metal, to obtain a composite mixture, and forming a solid mass from the composite mixture from step (i). A solid element obtained from the solid mass from step (ii) is inserted into a metal tube, and the metal tube from step (iii) is deformed, to obtain an elongated electrically conducting element.

Abstract: An arrangement is provided at least one superconductive cable (4) and a first cryostat (K1). A second cryostat (K2) is provided, formed coaxially with and at a distance from the first cryostat (K1). Arranged in the intermediate space (12) between the first cryostat (K1) and the second cryostat (K2) is a high voltage resistant insulation (16) which completely surrounds the outer pipe (10) of the first cryostat (K1), and which rests on the latter, where liquefied gas conducted during the operation of the arrangement flows through the intermediate space (12) around the insulation and impregnates the insulation.

Abstract: A conductor for transmitting electrical power having a cylindrical core (1) clad with a strip of metallic material (2), possibly comprising a superconductor, placed, in the shape of a tube, longitudinally around said core (I), its longitudinal edges being welded to each other along a weld seam (3). The core (1) has a slot (4, 4?) placed under said weld seam (3).

Abstract: A coated conductor with a substantially round cross section has a high temperature superconductor layer which is sandwiched between an inner substrate layer and an outer substrate layer to place the high temperature superconductor layer in the region of neutral strain axis.

Abstract: A method of fabricating a cable and the cable obtained by implementing the method. The cable comprises a central conductor of aluminum covered in a layer of copper, said method improving the mechanical characteristics of the cable, in particular in terms of elongation and bending, and increasing its lifetime. According to the invention, the method consists in interposing an intermediate layer of nickel, niobium, tantalum, or vanadium between the central conductor and the copper layer. The invention is applicable in particular in the aviation industry.

Abstract: A composite conductor is provided with multifilament superconductive strands soldered together. The strands are assembled together by a continuous solder joint over their entire length, the solder having a low melting point alloy.

Abstract: The invention concerns a method of making a superconductor so that it includes, in cross-section: a central area, made up of a plurality of superconductor filaments of the NbTi, NbTiTa type or of any other alloy or substance based on Nb; a concentric, two part, outer ring surrounding the central area; and a concentric resistive barrier. In accordance with the invention, the concentric resistive barrier is integrated into the concentric outer ring.
