Three elements are introduced in order to obtain a formula for the maximum permissible current through a superconducting cable in a current-carrying cable system: the current lead, the strand, and the section of strand adjoining the current lead (transition section). Each element is characterized by a certain number of external characteristics necessary and sufficient to allow for the properties of one element in the investigation of another. Introduction of the external characteristics has made it possible to obtain formulas for calculation of the maximum permissible current in a cable having conductive current leads for various cryostatting arrangements. The validity of the formulas obtained has been confirmed experimentally with the aid of a full-scale section of single-phase coaxial type 1SPK-M superconducting cable. A comparative analysis has been carried out for this same cable of the effectiveness of various cryostatting arrangements; recommendations are given for increasing the maximum permissible current.
