This utility model discloses an ultra-low temperature radio frequency coaxial cable, comprising an inner conductor, an insulator, an outer conductor, and a sheath arranged sequentially from the inside out. It also includes a superconducting reinforcement layer, a buffer compensation layer, and a vacuum insulation layer. The superconducting reinforcement layer is disposed between the inner conductor and the insulator, and the buffer compensation layer is located between the insulator and the outer conductor. The inner and outer sidewalls of the buffer compensation layer are respectively attached to the outer sidewall of the insulator and the inner sidewall of the outer conductor to absorb the stress caused by the difference in thermal expansion coefficients between the inner and outer conductors under ultra-low temperature conditions. The vacuum insulation layer is fitted onto the outer peripheral wall of the sheath and has an insulating cavity inside. The superconducting reinforcement layer reduces the radio frequency loss of the inner conductor, while utilizing the superconducting Meissner effect to suppress eddy current interference in signal transmission, reducing the signal attenuation rate in the superconducting state, and effectively shielding low-frequency electromagnetic noise. It also absorbs the stress caused by the difference in thermal expansion coefficients between the inner and outer conductors under ultra-low temperature conditions.
