Technology of Copper Clad Aluminum

Update:2025-07-30 10:38
Summary:

 

     

● What`s CCA(copper clad aluminum) :

CCA is a new type bimetal cable material ,which can be used for many kinds of communication cable and power cable as core conductor,braiding wire and stranded wire.


● Know-how:

CCA contains less copper than pure copper cable,but it delivers virtually the same conductivity with only slightly higher resistance. How is this possible?

It has to do with an electrical phenomenon known as “skin effect.”

 


● What`s the type:

1-Pladed Type (10% Copper Weight)

2-Claded Type (10H/A & 15H/A)


● What diameter rangeit has:

0.12mm -8.00mm


● What applicantion it has:
1. Lan Cable   2.Telephone Cable   3.Coaxial Cable    4.Speaker Cable

5.RF Cable    6. THW Cable      7.Extension Cord   8.Boost Cable    9.Other cable

Note: In view of the resistance and conductivity.normally CCA is 1.2-1.5 times section area equal to Copper Wire.

 

Conclusion: CCA has lower cost than copper by same length
