Flexible Superconducting Power Cables

In view of the fact that installation costs may represent up to half the investment in an underground cable system, it is desirable to develop concepts for superconducting cables which, from the beginning, promise to keep this expense to a minimum. Superconducting cable will be very light and, providing it is flexible, the cable should be capable of being pulled in long lengths. Two concepts for flexible superconducting cables are presented together with a discussion of expected performance in the system.
