In a superconductive winding comprising a core on which is wound at least one stabilized superconductor and at least one intermediate element having a mechanical strength of the order of that of steel separating the turns of the conductor, the intermediate element and/or the superconductor is mechanically deformed prior to winding in such a manner as to possess undulations and/or raised portions. A stabilized superconductor 4 comprising a copper or aluminium sheath on wires, strips or cables of NbSn, NbZr or NbTi which have been plated with Cu, Ag or Au and subsequently indiumplated or tinned, is wound about former 12, e.g. of a non-magnetic light alloy or stainless steel, together with an intermediate strip 13 of Al alloy or stainless steel which has been coated with polyamide or epoxy resin. The stabilized superconductor may also take the form of a circular or square cross-sectional conductor with or without a central cooling duct (Figs. 11, 12, 13, 14 and 15, not shown). In other embodiments (Figs. 8, 9 and 18, not shown) the stabilized superconductor which may be corrugated, can have an insulating tape of glass fibre. or cotton impregnated with polyamide or epoxy resin wound about it helically, the tape providing channels for coolant fluid. A plate of stainless steel acting as the intermediate element and having transverse ridges of P.T.F.E thereon may be placed against one side of the wound superconductor, so that when the windings are made, corrugations are formed in the superconductor (Fig. 10, not shown). |
