1.Good quatity ,factory price,free samples
2.seven years' experience in this industry
quality control of CCA:
1)diameter range:0.15mm~3.0mm
2)standard:China SJ/T 11223-2000 and USA ASTMB 566-93
advantages of CCA wire:
1).DR Resistivity:Copper clad aluminium wire resistivity is 1.5 times that of pure copper wire. Copper clad aluminium wire weight is about 1.2 times thant pure copper wire on the same resistivity. According to the skin effect,its resistivity is the same with pure copper wire while above the 5MHZ. So Copper clad aluminium wire electric capactiy is as well as pure copper wire while is used in digital cable and singnal cable with high frenquency.
2).Compared with pure copper wire, Copper clad aluminium wire has no value for larceners, because it become impossible to depart the pure copper cladding layer from aluminium heart yarn,so it has special function of anti-burglary.
3). With light weight,CCA is easy to transmit and fixed, so to reduce labour cost.
4).Copper clad aluminium wire has better plasticity than copper wire, and it will never produce insulated oxide like aluminium, so it is easy to tackle with better conductivity.
5).Our products takes the international leading craftwork of cladding welding&drawing method, so even in the strict wringing test, it will never take off,craze or flake,having no harm to human health and environment.
specifications of CCA wire:
| Item | copper content | conductivity | tensile strength | elongation | density |
| 10A CCA | 25%~27% | 55%~58% | 140~150MPa | 10%~20% | 3.35 |
applications of CCA wire:
(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. cable braiding
