CCAM Wire
Copper clad aluminum wire is produced with the production process of cladding-welding- drawing method, by cladding planished copper stripe concentrically on the outer surface of the aluminium core, via several times of drawing and heat treatment, to meet customers' technical requirement on line diameter, mechanical property and electrical property. The copper clad aluminum wire characterizes by both the samll density of aluminum and the good conductivity of copper. This kind of bimetallic composite wire is suited for most electrical conductor applications.The processing method of CCA wire is similar to that of copper wire during cable manufacture.
CCAM Application
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; Leaky Cable; Soft Coaxial Radio Frequency Cable; Data 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.
This product adopt the welding and stretching technique that enable the products with high strength, light weight and good conductivity. It has overcome the disadvantages of Copper Clad Aluminum wire (the diameter is below 0.5mm) with low strength and easily broken. We have won a lot of customers since the products open to the market. Application:
1)Braiding as shielding layer in cable
2)As conductor for LAN cable
3) in the field which has higher requirement on tensile strength
4) Mechanics & electrics performance comparison betweeen CCA and CCAM
