Abstract

As a novel power transmission technology, high-temperature superconducting (HTS) cables offer significant advantages in terms of low losses and high efficiency, and have gradually become a key research focus in urban power grid upgrades. This paper compares and analyzes the differences in power losses between HTS cables and conventional cables within urban power grids, and discusses the advantages of superconducting cables in practical applications as well as the technical challenges they face. Through data comparison, the energy efficiency performance of different cable types under various load conditions is analyzed, further revealing the potential of HTS cables in reducing power losses, enhancing grid stability, and optimizing energy structures. Although the initial investment for HTS cables is relatively high, they offer clear economic and environmental benefits over long-term operation, making them suitable for wider application and promotion in future urban power grids.
