——Mechanical properties
In recent years, with the appearance of copper-clad aluminum cables，The expensive price of pure copper cable has also become cheaper, which has promoted the development of China’s wire and cable industry.Copper-clad aluminum is coating of copper on the surface of an aluminum or aluminum/steel alloy core，After drawing, the thickness of the copper layer is above 0.55mm.What are the differences between copper-clad aluminum cables and pure copper cables in terms of performance, what are the advantages and what are the shortcomings?
In terms of mechanical properties，The strength and elongation of pure copper conductor are higher than copper-clad aluminum conductor，pure copper is better than copper-clad aluminum in terms of mechanical properties.From the point of view of cable design, pure copper conductor has the advantages of better mechanical strength than copper-clad aluminum conductor,It is not necessarily required in practical applications,Copper-clad aluminum conductors are much lighter than pure copper,Therefore, the copper clad aluminum cable is lighter in overall weight than the pure copper conductor cable,This will bring convenience to the transportation of cables and the erection and construction of cables,Copper-clad aluminum is a little softer than pure copper, and cables produced with copper-clad aluminum conductors are a little better than pure copper cables in terms of softness.
