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.

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. - ---------------------------------------------------------------- This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
