The world’s longest and most powerful superconductor power transmission cable has been connected to the commercial power grid in New York, US – cooled by the innovative cryogenic technologies and competencies of Air Liquide.
Connected to the commercial power grid in Holbrook, New York by the Long Island Power Authority (LIPA) and American Superconductor, the 600m long cable is cryogenically cooled thanks to the advanced technologies of Air Liquide, the world leader in cryogenics.
The project demonstrates the operation of a high voltage superconductor cable in an urban commercial power grid. Capable of transporting up to 2,400 amps (574 MVA in a 138 kV system), the superconductor cable is the first such high voltage electric cable in the world to be operating in a real transmission system.
The cable transports more energy than all of the previously demonstrated high temperature superconductor (HTS) cables together, and is capable of powering up to 300,000 homes.
