Details Of Copper Clad Aluminum Wire

  • Advantages of CCA Wire:

    1. DC resistivity: the resistivity of copper clad aluminum cable is larger than that of pure copper wire, about 1.5 times that of pure copper wire. When the same cathode value is reached, the weight of the copper-clad aluminum power cable is about 1/2 of the pure copper wire.
    2. The use of copper-clad aluminum conductors can meet the habits of wire and cable product selection, design, use, installation, etc. These habits will continue for many years. It is also advantageous for the pressing and welding of cable terminals.
    3. Reduce AC resistance.
    4. It has good corrosion resistance: aluminum is more prone to corrosion than copper, but because the copper-clad aluminum material has been completely metallurgical, aluminum is completely covered by copper and will not be in contact with water or air, completely achieving the same performance as copper.
    5. Low cost and light weight: Copper-clad aluminum power cables can save more than 40% of the cost compared with copper cables with the same technical specifications. Copper-clad aluminum/copper composite conductor cables can save more than 20% of the cost. The proportion of copper-clad aluminum power cables is only 37%-40% of pure copper wires. The wire diameter and weight are equal to 2.5 times the length of pure copper wire.
    6. Good welding performance: The copper-clad aluminum cable has a layer of pure copper concentrically coated on its surface, which has the same weldability as pure copper wire, which is convenient for production.
