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 about 99 miles of high-temperature superconductor wire manufactured by American Superconductor, installed underground and chilled to superconducting temperature with liquid nitrogen.
The superconductor is bismuth strontium calcium copper oxide (BSCCO) which superconducts at liquid nitrogen temperatures. Other parts of the system include a 13,000 U.S. gallons (49,000 L) liquid nitrogen storage tank, a Brayton Helium refrigerator, and a number of cryostats which manage the transition between cryogenic and ambient temperatures.
