This kind of electric cable is made from CCAM/CCA which is produced with the production process of Cladding Welding Drawing method, by cladding planished copper belt concentrically on the outer surface of the aluminium line, via several times of drawing and heat treatment, to meet customers' technical requirement on line diameter, mechanics and electrics capacity. It is wide used in electric cable Leaky Cable, Data Cable and so on.

There forms a firm atom metallurgy combination between the copper layer and the aluminum core. Its surface is bright and smooth without any default.

This kind of wire is featured of both the samll density of aluminum and the good conductivity of copper. It is used as the conductor in coaxial cables. It not only has high signal transmission property, but also has characteristics such as low weight and low production cost.
