Title: Current lead using rutherford cable

Abstract: A normal conducting current lead using Rutherford cables, in which one end thereof is connected to an external power supplier and the other end thereof is connected to a superconducting current lead connected to a superconducting power apparatus operating at ultralow temperatures. The normal conducting current lead includes an insulating body, which has a cylindrical shape or a polygonal prism shape and a plurality of slots radially formed from the center thereof, and a plurality of Rutherford cables, which are inserted and fitted into the slots of the insulating body and are radially arranged so that a density of current flowing through the cross-section of the current lead is uniformly distributed.
