High Temperature Superconducting Cable for Railway System

In this paper, the authors present their design for the first prototype DC superconducting cable for feeding railway overhead contact wire systems. The superconducting cables will reduce the high resistive losses generated in the feeding system. For the preliminary evaluation, 2 m Bi-2223 DC cable is used. Results showed the maximum current flowing in the cable cooled by liquid nitrogen to be 1720A in the inner sheet wire and 2430 in the outer sheet. Leakage of magnetic field was determined to be negligible, and the authors conclude that the developed DC superconducting cables are reliable for use in railway systems.
