Abstract
Albany HTS cable project is going on with the support of US Federal and New York States. The HTS cables included the Bi2223 tapes sintered by CT-OP (controlled over-pressure) process has 34.5kV and 800A capacity. The cable system was manufactured in Japan, and shipped to Albany. A 320m cable and a 30m cable were installed into the conduits under the ground. Subsequently, a splice box was assembled in the vault, and two terminations were connected to the HTS cable on the ground. Cryogenic refrigeration system was also mounted at the site by BOC. Initial cooling process was conducted as measuring distributed temperatures along the cable. The results of off-grid test, i.e. measuring heat loss, pressure loss, critical current, and DC withstand test, were carried out successfully. HTS cable system was connected to the real grid on 20 July 2006. The cable has been operated stably for 3months as monitored by Remote Operation Center of BOC. This report outlines the installation and test results on Albany HTS cable project.
