WIPO Patent Application WO/2020/238048
Kind Code:
A1
Abstract:
A tensile OPPC preparing method, comprising: producing an aluminum-clad steel primary rod by using an aluminum continuous extrusion cladding method process, and performing wire drawing by means of a wire drawing die to form aluminum-clad steel single wires; using an A8 aluminum rod to prepare aluminum single wires by means of wire drawing, and placing the aluminum single wires into an aging oven for annealing treatment; twisting the aluminum-clad steel single wires to form a cable core, using a twist-removal wheel device to extrude the twisted cable core, and performing micro-machining and preforming on the aluminum-clad steel single wires. The technical solution of aluminum single wires spirally winding the cable core can be used for OPPC preparation.
