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.
