CCA cable--Copper clad aluminum wire 1. CCA cable--Copper clad aluminum wire, commonly abbreviated as CCAW or CCA, is a conductor composed of an inner aluminum core and outer copper cladding. 2. The Cable - Copper Clad Aluminum is made complying with the national standed and have pass the CCC (China Compulsory Certification which contains the recondition of national security certificate--CCEE,imports of safety and quality licensing system--CCIB,China Certification Electromagnetic Compatibility--EMC 3. CCA wire (copper clad aluminum wire) is a bimetallic wire with a copper cladding concentrically covering an aluminum core, and it combines the characteristrics both of the excellent conductivity of copper and the light-weight of aluminum, so it is a ideal material for most electrial conductor applications, such as coaxial cables , high-frequency signal transmission cables, control cables, electromagnetic cables and many other fields. 4. Copper clad aluminum wire advantages: Copper clad aluminum wire is produced by international advanced welding technology. The copper adopts the pure copper with 99.97% above density, copper layer is of high density, and good conductivity. Copper layer and aluminum wire can reduce the raw-materials largely the buyer. 5. Copper clad aluminum wire application areas: (1) For the high-frequency singal transmission: Flexible RF coaxial cable; Leaky in inner cable conductor ; Network cable inner conductor; Micro coaxial inner conductor; coaxial cable conductor material within the frist 50Ω; RF cable. Flexible RF coaxial inner conductor. (2) For electricity transmission: Wire material; Fuse; Power cable conductor; Bush conductor wiring construction materials; (3) For Bus conductor materials, ect.: Cars, Iocomotives cable conductor; Computer cables, control cables and other data cables with conducyors (4) For others: Audio, Video conductor, power line conductors, Computer peripheral lines, Computer lines row conductor material. 6.
