Planned Grid Installation of High Temperature Superconducting Cable in Albany, NY

A team consisting of an HTS systems manufacturer (SuperPower, Inc.), a global industrial gases company (The BOC Group), a cable manufacturer (Sumitomo Electric Industries), and an electric utility (Niagara Mohawk) is developing a 34.5kV HTS cable for installation in the distribution network in downtown Albany NY. Energization is projected for the fall of 2005. The cable will be rated for 800Arms, with all three electrical phases in one cryostat. The 350m long cable will be pulled through a duct that includes a 90 o bend. A field installed underground cable joint will allow for the replacement of a 30m section of the original HTS cable with a section manufactured utilizing 2 nd generation YBCO, in 2006.
