Problems solved by technology

At present, there are many deficiencies in the production process of ultra-fine copper wires in the prior art, such as: annealing can only be performed on a single anneal, and since the diameter of ultra-fine copper wires is about 0.05mm, if the ultra-fine copper wire is used in the annealing process Large traction will break the copper wire, and the copper wire needs to be connected to continue production, so the processing speed and production capacity of ultra-fine copper wire are restricted; at the same time, the ultra-fine copper wire produced by the annealing technology used in the prior art The silk has weak anti-oxidation ability and can only be used for about half a year before being oxidized and needs to be replaced constantly

Abstract

The invention provides a high-performance electrical copper wire which is composed of a plurality of strands of superfine copper wires. Each strand of superfine copper wires comprises 80-180 superfinecopper wires, and the diameters of the superfine copper wires are the same. The high-performance electrical copper wire has the advantages of being superfine, super-strong, resistant to oxidation, voltage, stretching and heat, long in service life and the like. In the production process, an annealing process is combined, multiple strands of superfine copper wires are annealed at the same time, the drawn steel wires are directly combined into one strand for combined annealing, and the subsequent weaving process is simplified; the whole production process is environment-friendly, energy-savingand emission-reducing; in the annealing process, carbon dioxide is introduced into the drying oven, cooling water contains an environment-friendly copper antioxidant, an antioxidant layer is formed onthe surface of the copper wire, and the antioxidant capacity is improved.

Description

technical field [0001] The invention belongs to the technical field of wires and cables, and in particular relates to a high-performance electrical copper wire and a production process thereof. Background technique [0002] Due to its softness and good electrical conductivity, ultra-fine copper wire is used more and more widely. At the same time, the wide application puts forward higher and higher requirements for ultra-fine copper wire, especially for the output and life of ultra-fine copper wire. put forward higher requirements. In the production process of ultra-fine copper wire, the annealing process of ultra-fine copper wire has always been an important aspect that restricts the output and quality of ultra-fine copper wire. At present, there are many deficiencies in the production process of ultra-fine copper wires in the prior art, such as: annealing can only be performed on a single anneal, and since the diameter of ultra-fine copper wires is about 0.05mm, if the ult...
