Hybrid High Ampacity Electric Power Cable

The Navy is interested in developing hybrid superconducting power transmission cables that would carry at least 5 kA of current and have a current density of at least 35 MA/m2. The cable should be able to carry 30 % of the rated current even when the superconducting cable fails. We propose to develop a hybrid superconducting cable, based on CORC cables, which potentially have a current density of 500 MA/mm2, while being extremely flexible. We will develop multiple cable designs, based on cold and warm dielectrics, and determine their feasibility for continuous operation at 30 % of rated current when the superconducting cable fails. A full-size hybrid power transmission cable will be delivered at the end of the proposed program.
