Copper clad aluminium wire is bimetallic wire consisting of an aluminium core cladded with copper,which simultaneously has the features of copper's good electrical conductivity and aluminium's light weight. It's the preferred material for inner conductor of coaxial cable and electrical equipment wire and cable.
Feature
Compared to copper conductors:
Higher Flexibility due to lower elastic modulus 63% material weight reduction due to lower specific gravity of CCA over regular copper
Compared to aluminum conductors:
Better corrosion resistance than aluminum due to copper layer. Lower resistance due to high electric conductivity of copper
Better solderability
Higher strength than aluminum
Application:
CCA wire widely used in Cable TV signal and large volume communications net work signal transmission, control signal cable , welding cable and so on.
High Frequency Signal Transmission :
1. Choice conductor material for : cable TV coaxial cable
2. 50Ω Radio frequency (RF) cable
3. Flexible RF coaxial cable inner conductor material
