Description
Future electric aircraft require lightweight and high-power-density electrical transmission systems. High-temperature superconducting (HTS) cables are therefore promising for cryogenic electric propulsion, but their practical application requires coordinated evaluation of the cable, terminations, electromagnetic behaviour, and insulation. This work develops a modular single-cable cryogenic platform for the integrated DC qualification of an HTS cable link. Critical-current tests were performed to evaluate the DC transport capability, while segmented voltage measurements were used to characterize the resistance of the soldered cable-to-copper terminations. A two-dimensional electromagnetic model was established to analyse the self-field and current-density distributions under DC operating conditions. Insulation-resistance and withstand-voltage tests were also conducted to verify the electrical integrity of the cable assembly. The proposed platform enables the superconducting cable, electrical terminations, and insulation system to be assessed within the same cryogenic setup, providing a practical basis for component-level performance identification and the development of reliable HTS power links for cryogenic electric propulsion and future high-power electric aircraft.
