The high temperature superconducting cable system will first be used in short-distance power transmission occasions (such as generators to transformers, substation centers to substations, underground substations to urban power grid ports) and short-distance transmission of large currents such as electroplating plants, power plants and substations. occasions, as well as large or very large urban power transmission ...

AI Technical Summary

Problems solved by technology

Among them, the current-carrying conductor is the current-carrying part of the high-temperature superconducting cable, and is the core component of the superconducting cable system. A circumferential magnetic field is generated between the layers, and the strength of the magnetic field at different positions is uneven, which affects the power transmission of the superconducting cable
