CCA wire is the abbreviation for copper-clad aluminum cable. The conductor in the CCA line is made of aluminum and then coated with copper. For a long time, many professionals have been skeptical of copper-clad aluminum wire. However, new evidence proves that in some applications, CCA wire has obvious advantages over pure copper wire.

When installing communication cables, CCA allows cables to take advantage of all the benefits that copper must provide, while maintaining a more affordable price tag and helping to protect the world's limited copper supply. Enameled aluminum wire is one of the main varieties of winding wires composed of conductors and insulating layers. The bare wire is softened after annealing, then a few pains, and finally baked.

Affected by factors such as the quality of raw materials, process parameters, production equipment, and the environment. Therefore, the quality characteristics of enameled aluminum wire and enameled copper wire are not the same. But they all have four major properties: mechanical properties, chemical properties, electrical properties, and thermal properties.

Enameled aluminum wire has high heat resistance, excellent mechanical properties, electrical and chemical properties, and excellent frost resistance. It is suitable for refrigeration equipment and chemically corroded electrical equipment, dry-type transformers, oil-immersed transformers and epoxy cast transformers under long-term working conditions of 200℃.
