HTS Degaussing Cable Navy SBIR FY2008.1 Sol No.: Navy SBIR FY2008.1 Topic No.: N08-085 Topic Title: HTS Degaussing Cable Proposal No.: N081-085-0684 Firm: Creare Inc. P.O. Box 71 Hanover, New Hampshire 03755-0071 Contact: Anthony Dietz Phone: (603) 643-3800 Web Site: www.creare.com Abstract: High Temperature Superconducting (HTS) cables offer major advantages over the conventional copper cables currently used to reduce the magnetic signatures of Navy ships. A degaussing system utilizing HTS cables would be smaller, lighter, and cost less to install than current systems. However, new components, cables, and connection technologies are needed before HTS systems can be considered for installation and operation in Navy ships. In particular, there are no suitable HTS cables currently available for this application. HTS cables being developed for electricity transmission have different voltage, insulation, and cooling requirements. Creare is pursuing a development program to provide the Navy with the technology needed to transition an HTS Degaussing System into the next generation of warships. As part of this development effort, we propose to develop an innovative HTS degaussing cable, in which up to 40 HTS conductors are installed in a flexible cryostat that is terminated with quick disconnect couplings. In Phase I of this project, we will develop a cable design and demonstrate that it will meet the Navy's requirements for this system. In Phase II we will fabricate full-length prototype cables using production fabrication techniques and demonstrate their performance in a degaussing system. Benefits: Our proposed HTS degaussing cable will remove one of the key technical hurdles facing the introduction of superconducting systems into Navy warships. Superconducting technology has the potential to reduce the size, weight, and cost of certain systems such as degaussing systems, propulsion motors, and power electronics. Aspects of the design may also be suitable to DC voltage power transmission cables. Return
