Copper Clad Aluminum Wires – the Best of Both Worlds

The term CCA wire is the name for a wire made by the combination of copper and aluminum to bring out the best qualities of both so they can be used as alternatives to the use of their standalone parent metals. The CCA wire is a bimetallic, which means a product made from the combination of two metals. A bimetallic has many advantages like being lighter in weight, long life hence better stability, cost lesser, are stronger, and have no scrap value so quite theft resistant.

This wire has a huge advantage over a solid copper wire and has gained popularity due to its long list of benefits. The starkest feature of this wire is its high electrical conductivity (approximately 63%) at only 37% of the weight of the original copper, which means that these wires offer better performance at less than half the weight.

The CCA wire comes in many sizes to which there are norms of minimal copper thickness, the weight, and the maximum allowable distance for them. These norms allow the industries/companies to choose the wires that fit their requirements the most. These are also produced as cylindrical or non-cylindrical wires and have varying copper densities to suit different industry needs.

The way they work is called the skin effect which is the process of alternating current so the concentration is more on the copper cladding, this causes the wire to reach the resistance equal to that of a pure copper wire at high frequency and this makes the CCA wire a good choice.

These wires also have branched out into CCA-M wires which are results of the combination of aluminum-magnesium wires to copper. These wires also have a very high electrical conductivity ratio and are only slightly heavier than the CCA wires and are mostly seen as single wires and contribute to electrical connections, and the plating of tin, silver or nickel to make them more adaptable to different applications.

Currently the CCA wires are being used all over the world and indifferent industries primarily due to their high electrical conductivity and less weight characteristics:

1 In the telecom industry they are used as distribution cables for the cable television industry, they offer huge cost savings and the promise of stable and longstanding cables

2 They are also used as detonation wires and a preferred in the mining industry due to their low cost large current carrying capacity

2 In the utility industry, these wires are very popular as they can carry electrical currents over long distances and also can absorb the fluctuations; which helps in minimizing the damage caused by such events

4 They are used in cable manufacture as they are flexible, do not corrode easily, and are easy to maintain
