Holbrook Superconductor Project
The Holbrook Superconductor Project is the world's first production superconducting transmission power cable.[1] The lines were commissioned in 2008.[2] The suburban Long Island electrical substation is fed by about 600-meter-long underground cable system consists of about 99 miles of high-temperature superconductor wire manufactured by American Superconductor, installed underground and chilled with liquid nitrogen to minimize power loss in the transmission lines.[3]
The superconductor is bismuth strontium calcium copper oxide (BSCCO) which superconducts at liquid nitrogen temperatures. Other parts of the system include a 13,000 US 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.[1]
The project was funded by the United States Department of Energy, and operates as part of the Long Island Power Authority power grid.[1]
