Description
Summary:The US Department of Energy is currently funding the design, development and demonstration of the first long length, transmission level voltage, cold dielectric, high temperature superconductor power cable. The cable is designed for permanent installation in the long island power authority (LIPA) grid and will be able to carry 574 MVA at a voltage of 138 KV. The project is led by American Superconductor and the team is comprised of Nexans, Air Liquide and LIPA. This paper will describe the goals of the project, an overview of the cable design, refrigeration system and site design. It will also include the statistics of the HTS wire manufactured for this project, the results of the qualification testing on a prototype 30 meter cable and the preparation work of the refrigerator system. The cable will be completed and put into service in the LIPA grid in 2007.
