description The invention provides a superconducting cable, a chromium-plated oxygen-free copper wire and a production process of the chromium-plated oxygen-free copper wire. The production process of the chromium-plated oxygen-free copper wire for the superconducting cable comprises the following steps: step S10, preparing an oxygen-free copper rod; s20, the oxygen-free copper rod is continuously extruded, and a copper rod blank is obtained; step S30, continuously extruding the copper rod blank to obtain a copper monofilament; s40, drawing the copper monofilament to obtain a hard copper monofilament; step S50, annealing the hard copper monofilament to obtain a soft copper monofilament; s60, the soft copper monofilaments are subjected to chromium plating; the diameter of the copper rod blank obtained in the step S20 ranges from 11 mm to 13 mm, and the diameter of the copper monofilament obtained in the step S30 ranges from 1.7 mm to 3 mm; moreover, the step S20 and the step S30 both comprise the steps of continuously ext
