About CCA Wire


    As in many professional industries, changes will occur over time rather than being immediately accepted. New technologies must prove their value and reliability, which can sometimes be tricky. After all, time is the best criterion for judging transmission trends and permanent trends.
    Copper-clad aluminum is a good example of an innovation that faced initial suspicion in the wire and cable industry.

    Solid copper
    For more than a century, 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? This is due to the high conductivity and low resistance of copper. But due to its wide range of uses and needs, copper is an expensive metal.

    Copper Clad Aluminum
    CCA wire allows the use of all the advantages of copper to significantly reduce costs within certain parameter ranges. At the same time, the CCA cable network helps to balance the global copper supply. The copper clad aluminum wire is composed of an aluminum inner core and a copper outer "skin". Although this wire contains less copper than solid copper wire, it provides almost the same conductivity but slightly higher resistance. This is possible because an electrical phenomenon called the "skin effect" occurs.

    Skin effects and CCA
    The skin effect causes the alternating current to be concentrated on the more conductive copper cladding of the conductor, causing the resistance of the wire to approach that of a pure copper wire at high frequencies.
    Due to the skin effect, cheaper metals (such as aluminum) can be used as the core material, and the outer layer is copper to achieve almost the same conductivity.

    Performance, cost and time
    Due to its unique combination of copper and aluminum, CCA can provide an economical solution without compromising performance and reliability. Its weight-conscious design simplifies installation and saves time and cost.
    With our ever-changing technology and innovation-driven world market, it is wise to be both cost-conscious and look for alternative solutions to the depletion of natural resources. Copper clad aluminum is covered.
