Detailed Description

In order to make the technical solution of the present invention better understood by those skilled in the art, the present invention will be described in detail with reference to the accompanying drawings and the detailed description.

As shown in fig. 1, a new bimetal wire comprises an aluminum conductor 1, and a bonding layer 2, a copper layer 3 and a shielding layer 4 which are sequentially coated on the outer side of the aluminum conductor 1; the bonding layer 2 is a nickel layer and a zinc layer. The composite conductor material with the structure has a good antistatic function and a good shielding effect on the basis of good conductive performance, greatly reduces the consumption of copper, and reduces the manufacturing cost of products.

In this embodiment, the shielding layer 4 is PET resin doped with an antistatic agent, and the antistatic agent contains one or more of carbon black and activated carbon fibers. The PET resin doped with carbon black and activated carbon fibers can effectively reduce the generation and the transmission of static electricity, obviously enhance the conductivity and play a role in preventing static electricity.

In this embodiment, the diameter of the aluminum conductor 1 is 1.7-1.9mm.

In this embodiment, the thickness of the copper layer 3 is 0.15-0.35mm.

In this embodiment, the bonding layer 2 has a thickness of 0.003 to 0.005mm. So that a copper-bonding layer-aluminum double-phase melting layer is formed between the bonding layer and the aluminum core and between the bonding layer and the copper layer, the copper is tightly wrapped on the aluminum core, and the bonding strength of the whole copper-clad aluminum wire core structure is improved.

Finally, it should be noted that the above description is only a preferred embodiment of the present invention, and that those skilled in the art can make various similar representations without departing from the spirit and scope of the present invention.
