A method developed by researchers at the National Institute of Standards and Technology (NIST) and the University of Colorado at Boulder for making thin, flexible, high-temperature superconducting (HTS) cables* has won a 2011 R&D 100 Award from R&D Magazine. The prestigious annual awards salute the 100 most technologically significant products introduced into the marketplace over the past year.
Designed to operate at -196° C (-353° F), the new superconducting cable has a diameter of less than 1 centimeter and is able to carry 2,800 amperes of current—three times as much as thicker, conventional copper or aluminum electrical transmission lines.
The cables are constructed by winding multiple HTS-coated conductors around a multi-strand copper core. The superconducting layers are wound in spirals in alternating directions.
According to developer Danko van der Laan, a University of Colorado scientist working at NIST, the main innovation in the compact cables is the tolerance of newer HTS conductors to compressive strain that allows use of the unusually slender copper core.
