The cable would be designed to handle the full 100 % electric power load under normal operating and battle conditions (i.e. a fully/partially functioning cryogenic cooling system operating at cryogenic temperatures ~ 50-60 K), and capable of handling 30 % of the rated power per the requirements of the N15A-T016 solicitation operating at warm ambient temperatures where high temperature superconductors would not normally operate. Benefits: High Temperature Superconductors (HTS) with their nearly no-loss transmission of Direct Current (DC) and low loss transmission of Alternating Current (AC), have the potential to dramatically increase the electrical power density over conventional all Cu/Al cables. Higher electrical power densities, cost containment, and the potential for enhanced capabilities such as FCL offer tantalizing incentives for pursuing HTS cables for electrical power systems for future naval ships architectures. This cable would have the added benefit of power transmission in both full load full functioning cryogenic state and also in a reduced load non-cryogenic (HTS failure/repair of cable or cryogenic system) scenario. This would be applicable to many power and energy distribution services. Return
