WORLD’S FIRST TRANSMISSION VOLTAGE SUPERCONDUCTOR
CABLE ENERGIZED IN LIPA’S POWER GRID

 

The world's first HTS power transmission cable system is pictured above. This system, which consists of three cables running in parallel in a four-foot wide underground right of way, is capable of carrying 574 megawatts of power. The three cables shown entering the ground can carry as much power as all of the overhead lines on the far left.

Cable System Able to Carry 574 Megawatts of Power to Local Residents and Businesses

Industry/Government Partnership Takes Major Step Forward in Development of Electricity Superhighways

Very Low Impedance Characteristics Enable Self-Adjusting, Secure Power Networks


Long Island Power Authority (LIPA) and American Superconductor Corporation (NASDAQ: AMSC) announced the operation of the world’s first high temperature superconductor (HTS) power transmission cable system in a commercial power grid.

The 138,000 volt (138 kV) system, which consists of three individual HTS power cable phases running in parallel, was energized on April 22, 2008 and is operating successfully in LIPA’s Holbrook transmission right of way.

The cable system, including six outdoor terminations for connection to LIPA’s grid, was designed, manufactured and installed by Nexans, the worldwide leader in the cable industry. The cable utilizes HTS wire produced by AMSC, which also is the prime contractor for the project. The 2,000-foot-long cable system is cryogenically cooled using a liquid nitrogen refrigeration system from Air Liquide.
