Abstract
A current lead for a superconducting rotary machine is constituted by a copper tube having a superconducting conductor fastened (e.g. by soldering) to a portion of its length, the entire length of the tube having copper cooling plates each of which blocks the bore of the tube leaving only a small hole for the passage of gaseous or hypercritical helium. The current lead is particularly applicable to the generation of electric power using cryoalternators.
