CCA Wires

Our leading product is the copper clad aluminum wire, 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. There forms a firm atom metallurgy combination between the copper layer and the aluminum core. Its surface is bright and smooth without any default. Therefore the copper clad aluminum wire is featured of both the samll density of aluminum and the good conductivity of copper. This kind of double-metal compound wire 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. The copper-clad aluminium conductor which produced by our company has two states, soft and rigid. It can be divided into 10% and 15% if a ccording to copper plate. 20 °C DC resistivity are 0.02743 Ω .mm 2 /m and = 0.02676O Ω.mm 2 /m. And nominal density are 3.32g/cm 3 and 3.63g/cm 3 , It is ( 37-40 ) % of fine copper lead. aspect ratio with same specification and weight is 1 : 2.5 - 2.7 . It can be extensively used in CATV signal transmission, HC communication network signal transmission, control signal cable, light vehicle cable, welding cable, urgent removal cable, TV exciting coil, deflecting coil, ballast coil and so on. In HF signal transmission, it is applied to: Standard Material of Conductor in CATV Coaxial Cable,50 Ohm Radio Frequency Aerial ,Soft Coaxial Radio Frequency Cable . In power transmission and LF signal transmission, it can be applied to: Twisted Pair Power Cable Control Cable Building Cotton Covered Wire Busbar & Other Conductors In special electromagnetic wire, it can be applied to: Coils or windings in computers, mobile communication equipments, spaceflight & avigation and military industry instruments
