Method for manufacturing cable for high-temperature gas cooled reactor

The invention discloses a method for manufacturing a cable for a high-temperature gas cooled reactor, and the method the following process flows: material selection-wire drawing-conductor twisting-finished product manufacturing-finished product packaging storage. The method is characterized by comprising annealing-extrusion of an insulating layer-extrusion of an outer sheath, wherein the annealing step means that an annealing silver plating machine is used for plating silver with the thickness of 6-20mu m on a copper monofilament surface; and the extrusion of the insulating layer and the extrusion of the outer sheath mean that screws with a high compression ratio of 3.5:(1-5.0):1 are used, extrusion equipment is provided with a good cooling device, the extrusion processing temperature of the extrusion equipment is controlled between 360 DEG C and 420 DEG C, a pipe-extrusion mould with the high extension ratio is selected as an extrusion mould, and the selected mating extension ratio is 30-50. The cable manufa
