TCCA-15H-0.31mm(Tinned wires) TCCA is CCA covered with a layer of tin which featured of the small density of aluminium and the good conductivity of copper. Copper clad aluminum wire is featured of both the small density of aluminum and the good conductivity of copper. Copper clad aluminum wire is produced with the production process of cladding welding drawing method, by cladding planished copper belt concentrically on the outer surface of the aluminum line, via several times of drawing and heat treatment to meet customers' technical requirement on line diameter, mechanics and electrics capacity.
It has th advantages of: (1)small density of aluminium (2)good conductivity of copper (3)high signal transmission property (4)light weight (5)low production cost
Copper clad aluminum conductors which produced by our company has two states: Soft and rigid. It can be divided into 10% and 15% if a according to copper plate. Its' resistivity are 0.02743 ohm. Mm2/m and 0.02676 ohm. Mm2/m. And nominal density are 3.32 g/cm3. And 3.63 g/cm3. It is (37-40)% of fine copper lead. Aspect ratio with same specification and weight is 1: 2.5-2.7.
