Copper Clad Aluminum CCAM is a composite conductor material consisting of an aluminum center conductor wrapped in a copper shell and a magnesium protective layer. A CCAM winder is a device used in the manufacture of wire and cable to wind CCAM wire onto a bobbin.

Copper-clad aluminum CCAM has a lighter weight compared to pure copper conductors because aluminum is less dense than copper. This allows for a reduction in overall weight and lower transportation costs when manufacturing wire and cable using CCAM conductors.

The copper shell of copper-clad aluminum CCAM provides good electrical conductivity, resulting in a wire with relatively high conductivity properties. However, due to the relatively low conductivity of aluminum, the overall conductivity is slightly lower than pure copper conductors.


The copper shell of the copper-clad aluminum CCAM provides good corrosion resistance and protects the aluminum center conductor from the external environment. At the same time, the magnesium protective layer can provide additional protection to further extend the service life of the conductor.

Copper-clad aluminum CCAM conductors have a lower cost compared to pure copper conductors. Aluminum is relatively inexpensive as the main component, while the use of copper shells can provide similar conductive properties to pure copper conductors, thus providing a competitive advantage in terms of cost.

Copper-clad aluminum CCAM conductors are widely used in wire and cable manufacturing. They are commonly used in low voltage applications, such as household wires, automotive wires, and communication cables. However, in high-voltage or high-frequency applications, pure copper conductors may be more common because pure copper has better conductivity properties.

A copper-clad aluminum CCAM winder is a device used to manufacture copper-clad aluminum CCAM conductors for winding CCAM conductors around a winding spool to form wire or cable. These devices are usually produced by specialized manufacturers and used in wire and cable manufacturing plants.
