Copper Clad Aluminum Wire (CCA): A solution to improve electrical system efficiency and reduce costs

Copper-clad aluminum wire is a composite wire material composed of an aluminum wire core and a copper outer layer. The copper outer layer is conductive, providing high electrical conductivity, while the aluminum core reduces the weight and cost of the wire. The production technology of copper-clad aluminum wire mainly takes into account the advantages of both aluminum and copper by coating the surface of the aluminum wire with copper.

The core advantages of copper clad aluminum wire
Reducing costs: Copper is expensive, while aluminum is relatively cheap. Copper-clad aluminum wires significantly reduce the overall cost of wires through copper-aluminum composites, and are especially suitable for large-scale power transmission and electrical system applications.
Light weight and easy installation: The density of aluminum is much lower than that of copper, so copper-clad aluminum wire is much lighter than pure copper conductors, which gives copper-clad aluminum wire significant advantages during transportation, installation and maintenance.
Good electrical conductivity: Copper has good electrical conductivity, and the copper cladding of copper-clad aluminum wire effectively improves the electrical conductivity of the wire. Depending on the coating ratio, the electrical conductivity of copper-clad aluminum wires can be close to or reach the level of pure copper wires, meeting most electrical transmission needs.
Corrosion resistance: Copper has strong oxidation resistance. The copper outer layer of copper-clad aluminum wire can effectively avoid oxidation of the surface of the aluminum wire and improve the long-term stability and service life of the wire.

Application areas of copper clad aluminum wire
Copper-clad aluminum wire is widely used in many fields due to its cost-effectiveness and excellent electrical properties. The following are some typical application scenarios:
