Abstract
A superconducting cable comprising an in-situ-formed type II superconductor, e.g. Nb.sub.3 Sn, in association with a stabilizing conductor both in heat transfer relationship with at least one passage adapted to carry liquified gaseous refrigerant. The conductor and said at least one passage are enclosed by a sheath comprising an alloy consisting essentially of about 49% nickel, about 4% chromium, about 3% niobium, about 1.4% titanium, about 1% aluminum, balance essentially iron.
Claims4
A superconducting cable comprising an elongated type II superconductor in association with a parallel stabilizing conductor both in heat transfer relationship with at least one passage adapted to carry refrigerant, said superconductor, said stabilizing conductor and said at least one passage being enclosed by a sheath comprising an alloy consisting essentially of about 46-50% nickel, about 3-6% chromium, about 2.5-3.5% niobium, about 1.25-1.65% titanium, about 0.8-1.2% aluminum, and the balance essentially iron.
