Abstract: A connector for a conductor of a power cable includes a hollow outer member configured to at least partially surround an exposed section of the conductor and configured to exert a force in an axial direction onto at least one electrically conductive inner member, and at least one electrically conductive inner member configured to be interposed between the outer member and the conductor, and configured to exert a force in a radial direction onto the conductor in response to the force in an axial direction.

Abstract: A superconducting lead comprises a supporting board (1) with at least one superconducting tape (3) adhered to it and extending from one terminal area of the lead to another. Respective metal end-fittings soldered to the superconducting tape (3) at each of its ends, and in each of the terminal areas at least one metal insert is bonded to the board (1) and also soldered to the corresponding one of the said end-fittings, so relieving the tapes (3) of mechanical stress. The board (1), or each of them, is preferably flat and may support two or more superconducting tapes (3) coplanar with one another on one or on each of its major faces. The metal inserts are preferably of copper and may be made by removing most of the copper cladding from a commercially available circuit board (1).
