What are the characteristics of CCA?

With the development of science and technology, copper-clad aluminum has been widely applied due to its numerous advantages. However, copper-clad aluminum has a wide range of applications. In order to help you better understand copper-clad aluminum, let's introduce its characteristics. We hope this will be of help to you.

1. DC resistivity: The DC resistivity of copper-clad aluminum wire is approximately 1.5 times that of pure copper wire, and with the same cross-sectional area, its weight is about 12 times that of pure copper wire. According to the "skin effect" calculation, at high frequencies above 5 MHz, the resistivity is the same as that of pure copper wire. Therefore, when used in digital cables and high-frequency signal cables, its electrical properties are the same as those of pure copper wire.

Compared to pure copper wire, copper-clad aluminum wire is of no value to thieves because it is almost impossible to separate the pure copper cladding from the aluminum core. Therefore, it can achieve additional anti-theft effects.

3. Copper-clad aluminum wire is lightweight, facilitating operation and installation. It can also reduce labor costs.

Compared to copper wire, it does not generate insulating oxides like copper does, making it easier to process and handle. Furthermore, it has better conductivity.

5. The product is processed using the internationally leading "cladding welding and drawing method" production process. Even in the most stringent twisting tests, it will not exhibit phenomena such as desulfurization, cracking, or peeling, making it harmless to any environment.
