[0002] Superconducting power devices are power devices designed using the conductive properties of superconducting materials, specifically superconducting cables, superconducting motors, superconducting transformers, superconducting current limiters, etc., which have the advantages of small loss, small size, and large capacity. Due to the technical particularity that superconducting power devices need to operate at low temperatures, the AC bushing needs to meet the environmental requirements of the temperature range of minus 200 degrees Celsius. The existing AC bushings must meet the ambient temperature of minus 60 degrees Celsius. For normal operation under medium and high current levels, it is necessary to provide an AC bushing with low temperature performance, high voltage insulation and low heat leakage performance
