Copper clad aluminum enamelled wire refers to the wire with aluminum core wire as the main body and coated with a certain proportion of copper layer. It can be used as the conductor for coaxial cable and the conductor of wire and cable in electrical equipment. Advantages of copper clad aluminum enamelled wire:

1. Under the same weight and diameter, the length ratio of copper-clad aluminum enameled wire to pure copper wire is 2.6:1. In short, buying 1 ton of copper-clad aluminum enamelled wire is equivalent to buying 2.6 tons of pure copper wire, which can greatly reduce the cost of raw materials and cable production cost.

2. Compared with pure copper wire, it has low value for thieves. Because it is difficult to separate the copper coating from the aluminum core wire, it receives additional anti-theft effect.

3. Compared with copper wire, it is more plastic, and does not generate insulating oxides like aluminum, which is easy to process. At the same time, it has good conductivity.

4. It is light in weight and convenient for transportation, installation and construction. Therefore, the labor cost is reduced.
