A superconducting cable includes a first conductor layer formed of superconducting wires, anal an insulating layer formed at the outer peripher y of the first conductor layer. The first conductor layer is an assembly of a plurality of superconducting wires obtained by forming an RE based superconductor layer on a metal substrate. The current is limited by an electrical resistance generated when the current of the first conductor laye r exceeds the critical current, thereby preventing the superconducting cable from being damaged. A superconducting cable line is formed of a base and a current limiter, which is formed by using the above-described superconductin g cable. Accordingly, when a current exceeding the rated current of the base flows, it can be damped. |
