Copper clad aluminum wire is the new products replacing the previous generation, widely recommended by the country.
Copper clad aluminum wire is divided into soft and hard state in the way of statement, but 10 percent to 15 percent according to the volume of copper layer. And every technology index has met the American ASTM B566-93 Standards.
The advantages of Copper clad aluminum wire:
1. DC Resistivity: the dc resistivity of copper clad aluminum wire is just 1.5 times than that of pure copper wire, and as the resistive rate is the same .
2.Well welded: cooper clad aluminum wire has the good welding capability as the pure cooper wire for its surface covered with a layer of cooper.
3. With light weight: the weight percentage between the cooper clad aluminum wire and the pure cooper wire is just 37% to 40%, so under the circumstance of the same weight and wire size, its length is 2.5 to 2.7 times that pure cooper wire, which has lower the production cost.
4. Soft quality of copper clad aluminum wire and easily processed
The physical characteristic of copper clad aluminum wire:
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 |
Its instructions:
(1) Put the products in the ventilated and dry place, normal temperature and 35%RH around;
(2) When operating, it is strictly prohibited to touch the whole line body directly by hand,preventing oxidative deterioration from sweats ;
(3) When doubling or strepsinema ,it is best for adjusting tension and cintrol the speed in 1500.
(4) Compare with the copper wire ,it owns timeliness . And once exceeding the date, pull away the surface and reducing speed for using with the 8% elongation .
