High Temperature
Superconducting Wire
(2nd
Generation HTS Wire)
Technology
The last 20 years have witnessed a revolution in
superconductor science. As the critical temperature
(Tc) of superconducting materials rises, so does the
promise of the practical application of loss-free
transmission of electric power. However, high
temperature superconductors (HTS) are ceramics and
present a fundamental problem for wire fabrication:
they are brittle.
"First Generation" powder-in-tube HTS wire has
relied on traditional wire drawing technology and
variations on the compound Bi2Si2Ca2O7 (Tc = 112oK).
Powder-filled silver tubing is pulled through a form and
rolled to create sheathed superconductor filaments
