Features:

copper clad aluminum wire1) Adopts the advanced cladding and welding manufacturing technology, to clad the copper on the surface of the aluminum poles, and to make the fixed atom metallurgical combination of copper layer and core wires2) These two different metals can be combined into an integral part, which can be treated for drawing and annealing, like processing single metal wire3) In the process of drawing, the diameters of copper and aluminum are changing with the same ratio, thus the volume ratio of the copper surface can keep relatively permanent unchanged4) As the high frequency signal has the feature of conductor skin effect, so the copper-clad aluminum wires have the same conducting effects with the pure copper wires when the high frequency of signals is more than 5MHz5) Can be processed to be bare wire, tinned wire, flat wire and silver wire with various specifications6) The density of CCA is 37 - 40% of that of copper, the length is 2.45 - 2.64 times of copper in same weight and diameter7) All of these contribute to reduce production cost for cable manufacturers, even up to 55%8) Helpful to save copper resource by using copper-clad wire9) The finished cable will be easy to transport and install, because of light weight, and thus labor force is reduced
