Holbrook Superconductor Project

The Holbrook Superconductor Project is the world's first production superconducting transmission power cable. The lines were commissioned in 2008. The suburban Long Island electrical substation is fed by a 600 meter long tunnel containing approximately 155,000 meters of high-temperature superconductor wire manufactured by American Superconductor, installed underground and chilled to superconducting temperature with liquid nitrogen.
