CCAM (Copper clad Aluminum and Magnesium wire)
Adopted international advanced welding technology in the production of coated Jing tong above grade level by 99.99% copper, copper layer of high density, good conductivity
Copper clad aluminum and magnesium core line among the metallurgical copper layer evenly distributed along the circumferential direction and vertical, concentricity good. B566-93 various product standards and technical specifications in accordance with "ASTM standard E: SJ/T11223-2000as copper wire" acceptance.

1. CCAM wire integrates the beneficial properties of good conductivity of copper & light weight of aluminum in a single wire.
2. The density of CCAM is about 40% of that of copper. Its length is 2.4 times of copper in the same weight & diameter. These factors reduce the raw material cost for cable manufacturers.
3. CCAM has the high tensile strength it makes the customer un-interrupted in the using.
4. Environment friendly, CCAM saves the copper resources & its production is a nonpolluting process.

CCAM wire is widely used in the transmission of CATV information, communicative network with large capacity, controlling the information cable, light cars cable, welding cable, emergence movement cable, TV exciting loop, deflecting loop, ballast loop and other aspects.
Our factory has successfully innovated the productive technology of CCAM wire, refurbishing the blank history in 2005 and became the one of the pioneers in manufacturing and promoting CCAM, CCA products, for which we were awarded as a "high-tech enterprise" by the Shenzhen government. In 2008, we participated in drafting five national standards of electric cables, which were made into effect on March 19, 2009. In 2009, we also applied patents for new methods in manufacturing symmetric electrical cable using CCAM (Patent No. 200910108197. X\200920133715.9)
Our factory can produce the thinnest wire products with Product conductivity of 53% to 60% and wire size of 0.10 to 2.05, CCAM conductors which produced by our factory has two states: Soft and rigid. It can be divided into 10% and 15% if a according to copper plate.
