Аннотация	A possible design of an HTS DC cable that can be used to reduce the electricity consumption by an urban railway system is discussed. The proposed engineering solution is seen as an e৽cient alternative to a conventional power transmission system in densely populated areas owing to high current density and smaller cross section area of the HTS cable, as well as lower total losses in comparison with currently used AC systems. During the study, the electromagnetic characteristics of a coaxial DC cable for typical operational speci¿cations, namely, 20 MW, 750 V DC, and 26. 66 kA, were modeled. Supposedly, the cable line will be made on the basis of 4 mm wide and 0. 15 mm thick YBCO SCS4050 HTS tape produced by SuperPower Inc. For calculating the maximum current in the cable, a modi¿ed anisotropic critical state Kim’s model is used. The COMSOL Multiphysics 6. 2 software package is used for simulation. The designed cable has the critical current capability equal to 34. 23 kA, which is by 28 % higher than the total transport current of the cable, thereby con¿rming the Àexibility and correctness of the design proposed. Key words: high temperature 2- nd generation superconductor, DC cable, Kim’s model, critical current
