Nexans to manufacture superconductor cable for US Department of Energy's $30 million project on Long Island
Paris, April 23, 2003 - Nexans has been awarded the contract to manufacture the cable and cryogenic insulation system for the US Department of Energy's (DOE) $30 million high temperature superconductor (HTS) power transmission cable project in the Long Island Power Authority (LIPA) transmission grid. The 610 meter segment will be the world's first installation of a superconductor cable in a live transmission grid.
Nexans will fabricate the superconductor cable using HTS wire manufactured by American Superconductor (AMSC), a leading electricity solutions company. AMSC has been selected by the US DOE as prime contractor for this project. A Nexans CRYOFLEX( vacuum-insulated flexible cryogenic envelope will provide the thermal insulation required to maintain the cable core at its operating temperature of about -200°C. Air Liquide will provide refrigeration equipment and oversee operation of the cryogenic cooling system.
The 610 meter transmission circuit, capable of powering 300,000 homes, will be located underground in an existing right of way. With a capacity of 600 MW, the 138 kV superconductor cable system will be an integral part of the LIPA grid and is expected to be installed and operating by the end of 2005.
Yvon Raak, President of Nexans' Energy Division, said: "We are delighted to be participating in this important project. The growth opportunities for superconductor cables are enormous and this reinforces our position as a key participant in the market."
