Physical properties of copper clad aluminium is a kind of metal composite material, which displays the properties of two metal materials on one wire. Copper clad aluminum wire combines the excellent conductivity of copper and the advantages of light aluminum proportion to form a light conductive material.In addition, from the cable cost, in case of the same load flow ,the choice of copper clad aluminum cable is completely feasible. It can not only make cable manufacturing enterprises avoid risk but also can limit the rise in copper price.


copper clad aluminum cable has the following advantages:

(1) the heat circulation indexes between conductors and terminals are better than copper;
(2) its resistance and current carrying capacity are better than copper, so the wire loss is lower than copper.
(3) its contact resistance is the same as copper;
(4) its resistivity can be solved by conductor section, copper content and composite conductor.


With the shortage of copper conductive materials,the trend of wire and cable industry towards light quality, high strength, high conductivity, anti-magnetic and anti-corrosion is the inevitable trend of development.Copper clad aluminum wire saves a lot of raw copper resources, reduces the weight of cables, facilitates transportation and construction, reduces the labor intensity of workers, and the production process of coating welding method does not pollute the environment.Therefore, copper clad aluminum cable not only has a broad market prospect, but also has a wider application range.With the deepening development of market, copper clad aluminum cable has gradually been accepted by people, and various advantages of this product have been reflected in practice.
