CCA Wire Is Widely Used In Electrical Applications
-
CCA wire is popular because of the high conductivity of copper and aluminum, and copper provides additional strength to aluminum wire.
For more than a hundred years, solid copper has been the standard material for many wiring applications. Since the first electrical wiring system in the 1800s, copper conductors have been used. On the other hand, insulation methods and connectors have changed over the years. So how does copper maintain its popularity? Well, this is due to the high conductivity and low resistance of copper. But due to its wide range of uses and requirements, copper is an expensive metal.
Copper-clad aluminum is within certain parameters, and copper-clad aluminum can make full use of all the advantages of copper, thereby greatly reducing costs. At the same time, the CCA cable network helps to balance the global copper supply. The copper clad aluminum wire consists of an aluminum inner core and a copper outer "skin". Although there is less copper in the wire than solid copper wire, it provides almost the same conductivity but slightly higher electrical resistance. It is possible because of an electrical phenomenon called the "skin effect".
The skin effect causes the alternating current to concentrate on the more conductive copper cladding of the conductor, which causes the resistance of the wire to approach that of a pure copper wire at high frequencies. Due to the skin effect, lower-priced metal can be used as the core material, and the copper outer layer can actually achieve the same conductivity.
Due to its unique copper and aluminum bonding, the copper-clad aluminum rectangular enameled wire can provide an economical solution without compromising performance and reliability. Its weight-conscious design simplifies installation, saving time and cost. With our ever-changing technology and innovation-driven world market, it is wise to not only focus on costs but also find alternative solutions to the depletion of natural resources.
