The stability of cold insulation high temperature superconducting （HTS） cable has become an important subjectfor the practical application of HTS cable.The zero resistance propertyof superconductors and low-temperature stability theory were described.The paper built an equivalent circuit model of superconducting cable and the steady-state current distribution model.The simulation and calculation of the maximum radial temperature rise of superconducting cables in steady state were conducted by finite element analysis softwareANSYS and mathematical modeling.The influence of layer currentsdistribution on the stability of superconducting cables was analyzed,before and after optimization.The steady performance testing experiment of HTS cables was executed.The experimental measurements and analysis of the maximum radial temperature rise of superconducting cable were conducted under the currents with different amplitudes and frequencies.
