description: This study aims to reduce power consumption of Lahoreâs urban railway system by proposing a lossless and efficient design of HTS DC cable. It is a competent alternative to transfer huge amount of power with high current density in densely populated areas by reducing T&amp;D losses comparing with currently employed AC systems. Our design procedure covers the electromagnetic and thermal studies of DC coaxial cable with required operational specifications of 20MW, DC 750 V and 26.66 kA. In electromagnetic modeling, Superpowerâs YBCO SCS4050 HTS tapes 4mm wide and 0.15 mm thick are used and modified Kimâs model proposed by Gomory et al is applied while calculating critical parameters of the cable. In thermal analysis, a suitable 1700m long cryogenic system is designed by calculating mass flow, pressure drop and heat transfer from environment to LN2, flowing in return outer cryogenic pipe and covered a cable length of 850 m. COMSOL Multiphysics 6.2 is used for simulation. Our cable design significantly reduces power losses when replacing the AC network to connect two urban railway traction substations, resulting of 15.7% reduction in power consumption. The research proposes integrating HTS DC cables across various railway sections to optimize overall energy consumption.
