Re: [PSES] CCA cables

[Doug Powell]

In order to make use of CCA wire with mains you must have connectors rated for 
both copper, aluminum and alloys of copper and aluminum. I work with mains 
connections up to 1000 amps/phase and this is a very common question. Not only 
do you need this rating on your components but you should also mention this in 
your technical certification file ‎and in your user documents.  

All the best, Doug

Subject: [PSES] CCA cables

I would be interested in hearing from anyone with experience of testing or 
using copper coated aluminium (CCA) conductor cable in mains power 
applications. 

CCA is already widely used for network and booster cables but there now seems 
to be a move to use it in flexible power cord applications (specifically, 
portable extension cables). 

The corrosion problems associated with the use of aluminium are well known and 
I am familiar with the physics and chemistry involved. I’m less familiar with 
how much difference a copper coating makes. 

I’ve so far failed to find any standards which specifically address the 
performance or use of CCA cables, and I’m not familiar enough with the 
standards for copper cables to know valid it would be to apply these to CCA. 

All insight welcome!

Nick.

Re: [PSES] CCA cables

[John Woodgate]

A Google search shows a number of negative issues. One thing that appears not 
to be addressed is corrosion. Aluminium is not totally immune to corrosion when 
chlorides are present, and chlorides are everywhere (except, we hope, in an 
electrolytic capacitor factory). So considering the electrochemistry, once the 
oxide layer on the aluminium is breached, electrolytic corrosion could be very 
fast.
