Problems solved by technology

[0003] Therefore, using graphene's excellent electrical conductivity to obtain greater transmission capacity and lighter weight cables has great application prospects, but if large-diameter copper wires are used to coat graphene to improve power transmission capacity, it is not conducive to the safety of wires. lightweight

Embodiment 1

[0021] Such as figure 1 As shown, a copper-clad aluminum wire includes an aluminum core 1, a copper cladding layer 2 is provided on the outside of the aluminum core 1, and a graphene film layer 3 is provided on the outside of the copper cladding layer 2.

[0022] The cross section of the aluminum core 1 is circular.

[0023] The material of the copper cladding layer 2 is refined copper with a purity of 99.97% or more.

[0024] Concave-convex ribs 4 are provided on the bonding surface of the aluminum core 1 and the copper cladding layer 2 .

[0025] The graphene film layer 3 is formed by chemical vapor deposition.

Embodiment 2

[0027] The difference between this embodiment and Embodiment 1 is that the section of the aluminum core is rectangular.

[0028] The use of the copper-clad aluminum wire of the present invention is not only beneficial to the transmission of high-frequency signals, but also very beneficial to the transmission of DC or low-frequency high-power electricity. The use of the aluminum core increases the outer diameter of the wire while ensuring light weight, thereby The attachment area of ​​the graphene film layer is increased, which is more conducive to the transmission of high-power electricity. Even if there is no skin effect, the aluminum core, copper cladding layer and graphene film layer can be regarded as three wires used in parallel to give full play to the high conductivity of graphene.

Abstract

The invention relates to a copper-clad aluminum conductor which comprises an aluminum core. The copper-clad aluminum conductor is characterized in that a copper cladding layer is arranged outside the aluminum core, and a graphite film layer is arranged outside the copper cladding layer. The section of the aluminum core is round or rectangular. The copper cladding layer is made from 99.97% pure refined copper. Joint surfaces of the aluminum core and the copper cladding layer are provided with grooves and ridges. The graphite film layer is made by chemical vapor deposition. The copper-clad aluminum conductor has the advantages that the lightweight aluminum and the high-conductivity graphene enable the copper-clad aluminum conductor to be light in weight and high in current carrying capacity, and accordingly the copper-clad aluminum conductor is more widely applicable.

Description

technical field [0001] The invention relates to the technical field of wire manufacturing, in particular to a copper-clad aluminum wire. Background technique [0002] Copper-clad aluminum wire is a bimetallic composite wire that concentrically coats the copper layer on the aluminum core and forms a metal bond at the copper-aluminum interface. It is an updated product of copper wire. The existing copper-clad aluminum wire uses the current trend Skin effect characteristics, generally used in the transmission of high-frequency signals, it is rare for high-current transmission of DC or power frequency. However, graphene copper has very superior properties in terms of conductivity and toughness. Graphene copper wire and pure copper wire have the same weight and diameter, but their conductivity and toughness are increased by dozens of times; and their heat transfer rate is high, and the current density tolerance is dozens of times that of pure copper; Moreover, the electrical n...
