Abstract:
1. A joint for a superconducting cable, the joint being for jointing two lengths of the superconducting cable with each other, the superconducting cable comprising a former, a superconducting conductor, and an insulating layer; the construction of the joint comprising the steps of: (a) preparing a jointing ferrule for jointing the formers; (b) sliding the jointing ferrule over the end portions of the formers to be jointed; (c) butting the end faces of the formers against each other in the jointing ferrule; (d) compressing the jointing ferrule onto the end portions of the formers to be jointed so as to joint the formers such that the compressed ferrule and one of the end portions have a combined diameter approximately equal to that of a remaining portion of the former of the superconducting cable; (e) butting the end faces of the superconducting conductors to be jointed against each other at the outside of the compressed ferrule; and (f) jointing the superconducting conductors with each other such that the jointed superconducting conductors have a diameter equal to that of the superconducting conductor of the superconducting cable.
