What is CCA?

The most common alternative to copper used in the electrical industry is aluminium. Widely used in power distribution, many aluminium cables are buried under the road as power cables. CCA wire is an aluminium conductor with a thin copper coating. It’s made by encasing a rod of aluminium in a layer of copper strip which is butt-welded along the seam to totally encase the aluminium. The entire rod is drawn through a series of rollers and dies to reduce the diameter to as little as 0.1mm, just over the thickness of a human hair. The main disadvantages are its lack of flexibility, higher resistance and lower conductivity compared with copper. This means you have to use more of it to carry the same current or amps.

The appearance of CCA wire is the same as the other copper wires on the outside because it is actually aluminum and coated with a thin layer of copper. You need to look at it head-on to see the aluminum in the middle. Compared with wires made entirely of aluminum, CCA has better electrical conductivity. Copper coating helps, but it's still not as good as pure copper wire. It is also stronger than pure aluminum wire, but weaker than pure copper wire.

We are committed to providing customers with high-quality magnet wires with an uncompromising attitude.

Enameled wire is a wire coated with a thin insulating layer to prevent short-circuiting the wire surface when it is wound into a coil. When current flows through the coil, magnetic flux is generated. It is mainly used in the construction of motors, electromagnets, transformers and inductors. To facilitate the manufacture of inductive components, such as transformers and inductors, most of these wires can be welded.

We provide all types of electromagnetic wires that meet your electromagnetic requirements, including motors, transformers, control equipment, relays, generators and solenoids. Aluminium Magnet wire is also our responsible product.
