Abstract
A hybrid cable generally comprising a superconducting material and a material consisting at least partially of a conventional conductor. In operation, the hybrid cable is chilled to superconducting temperatures, wherein current primarily passes through the superconducting material. If the superconducting material loses performance, e.g., is quenched, current will flow primarily through the chilled conventional conductor. In the event hybrid cable temperature further increases, the current will travel through the conventional conductor at its normal capacity.
