The Navy has expressed interest in shipboard high-temperature superconducting (HTS) cable systems for power transmission and degaussing purposes. The practical application of such cable systems require flexible superconducting cables and cable connectors that allow for a quick and reliable installation into, or removal from, its pre-installed cryostat. Advanced Conductor Technologies LLC (ACT) of Boulder, Colorado and the Center for Advanced Power Systems at Florida State University propose to develop flexible Conductor on Round Core (CORC) cables and reliable, low-loss CORC cable terminations and connections for their application in shipboard helium gas-cooled power transmission systems. The CORC cable that is being commercialized by ACT is currently the only HTS cable that is flexible enough to be pulled through a pre-installed cryostat. During the Phase II program, we will design and construct CORC cables, terminations and connectors for 2-phase dc and 3-phase ac power transmission.
