Copper clad aluminum cca electric wire
1.Specification: 0.08mm-5.0mm
Our state-of-the-art cladding and welding crafts guarantee the high density and conductivity of 99.97% purity copper clading, while our metallurgical bonding technique assures that the copper cladding is evenly distributed around the aluminum core along the wire for excellent condentricity, technical parameters according with US ASTM B56693 Standard. According to the mechanical properties, CCA wire is sorted into Hard-drawn(H) and Annealed(A). According to the process, it can be divided into cladding CCA and plating CCA.
Standard: SJ/T11223-2000
ASTM B 566-93
2.Main perameter
Product spec | Copper layer (volume ratio%) | Copper layer (quality ratio%) | Density (g/cm3) | DC Resistivity (Ωmm2/m) | DC Conductivity (%IACS) |
CCA-10% | 8-13 | 27 | 3.32 | 0.02743 | 63 |
CCA-15% | 13-17 | 37 | 3.63 | 0.02676 | 65 |
Pure copper wire | 100 | 100 | 8.89 | 0.01724 | 100 |
3.Application
CCA is widely used in cable TV signal and large volume communications network signal transmission, or as control signal cable,welding cable.
High Frequency Signal Transmission:
1: Choice conductor material for cable TV coaxial cable
2: 50Ω Radio frequency(RF) cable
3: Flexible RF coaxial cable
4: Computer cable and other data cable
5: Superfine coaxial cable
Power Transmission :
1: Choice conductor material for Enameled wire
2: Power cable
3: Control cable
4: Cables specially made for automobiles and motorcycles
5: Construction wiring
6: Bus-bar
7: Fuse
8: RF shielded cable network
Special Magnet Wire:
1: Choice conductor material for Computer
2: Mobile communications wire
3: Coil or column used in Aeronautics and Astronautics or Military Devices.
4.Advantages
1) Given the same weight and diameter, CCA wire measures 2.6-3.2 times longer than copper wire, which means that 1 Ton of pure copper wire should afford 2.6 to 3.2 Ton CCA wire, a choice to reduce costs of material for cable production.
2)According to pure copper wire, the impossibility to separate copper from CCA wire keeps thieves away.
3)CCA wire is better plasticity than copper wire with good conductivity and improbability of insulating oxide to be generated round the aluminum core make the CCA wire easier to process.
4)CCA wire is light, easy to transport and install, thus saves labor cost.
5)With apparant social benefits, CCA wire saves lots of copper.
