NOVELTY - Copper wire comprises 22-30 pts. wt. brass, 25-32 pts. wt. red copper, 6-8 pts. wt. industrial silver, 11-14 pts. wt. graphene, 8-12 pts. wt. aluminum, 7-10 pts. wt. tungsten, 6-10 pts. wt. nickel, 5-8 pts. wt. iron, and 5-7 pts. wt. nano graphite. USE - Copper wire for wind power generation motor. ADVANTAGE - The copper wire has small resistance, is added with graphene on the base metal copper, aluminum, tungsten, nickel, iron and nanometer graphite with high conductive coefficient, and plating a layer of industrial silver on the outer side of the formed copper wire. The conductive efficiency of the silver is better than that of copper, as the price of the silver is high, then the wire is not normally used in the industry. The outer side of the copper wire is plated with one side of industrial silver, so that the dosage is less and the price of the industrial silver is not high. The added other metal enhance the anti-pressure ability of the copper wire, so that the wire is not easy to be broken. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing copper wire, which involves: (A) selecting a certain proportion of brass, red copper, aluminum, tungsten, nickel and iron, putting into a heating furnace for high-temperature heating to melt the materials, and cleaning out impurities in the molten materials; (B) pouring the material in a molten state into a heat-resistant mold, cooling the material by using cooling water after heating, putting the material and the mold into a cooling pool, and taking out the molded mold piece from the interior of the mold; (C) transporting the cooled formed membrane to an electrolytic cell to remove impurities; (D) transporting the die continuously with the impurities removed to a smelting workshop, and placing the die in a heating furnace for high-temperature heating again until the die is melted; (E) cooling the melted alloy water, stretching the alloy water into a copper rod, and carrying out acid washing, alkali washing and cleaning on the copper rod, and then carrying out wire drawing after transportation; (F) drawing a large-size copper wire by using a copper rod, using a continuous drawing and continuous annealing unit, carrying out wire drawing, annealing, cooling and drying take-up processes by using a giant drawing machine, paying attention to the normal operation of a steam protective gas device during continuous annealing, using a wire drawing emulsion containing an antioxidant, preventing residual wire drawing liquid from being left on the surface of the copper wire, wrapping the copper wire by using a plastic film after wire drawing and coil setting, and storing the copper wire in a dry environment; (G) drawing, melting the industrial silver to be in a molten state, coating the industrial silver on the outer side of the copper wire, drying, polishing, coating 2-mercaptobenzimidazole on the outer side of the copper wire, where the 2-mercaptobenzimidazole allows to generate a passivation film on the outer side of the copper wire to be used as a surface treating agent; and (H) bundling the copper wires, bundling and twisting the lower disk of the conductor, wrapping the conductor with a plastic film, and storing the conductor in a dry environment to get desired product.
