technical field [0001] The invention relates to the technical field of superconducting cables, in particular to a method for manufacturing an electrified conductor of a high-temperature superconducting cable. Background technique [0002] High-temperature superconducting cable system is a power facility that uses unimpeded superconducting materials that can transmit high current density as a conductor and can transmit large currents. It has the advantages of small size, light weight, low loss and large transmission capacity. Realize low-loss, high-efficiency, large-capacity power transmission. 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 l...

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
