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.
