The main composition of copper clad aluminum wire. Copper Clad Aluminum Wires consist of an internal aluminum core and an external copper cladding, and are commonly used for voice coils in headphones or speakers, as well as certain RF and connection and grounding applications.

CCA cables are much lighter than pure copper but stronger than pure aluminum, so CCA cables have been used in some electrical applications to avoid the problems inherent in aluminum wire connections, and because they are cheaper than pure copper.

Unfortunately, CCA cables have also become a cheap alternative to the category of twisted pair communication cables, but they should not be deployed in the network infrastructure. CCA cables do not comply with UL and TIA standards, both of which require the use of solid or stranded copper conductors.

Even if the CCA conductor does pass the termination and pass the test, aluminum will oxidize when exposed to air. Over time, this may eventually lead to termination failures and require troubleshooting.

Another problem with CCA is that it has a higher DC resistance (about 55% higher) than copper, which is not a good sign for PoE applications. Larger DC resistance will cause the cable to heat up more and reduce the available power of the PoE device. As we move to higher power PoE Plus applications, DC resistance will become more important. rectangular enameled wire is also our product.
