Bottom line Alu cable was and is cheaper than copper and was utilised mostly for larger CSA as a saving, I even remember in the 70's Alu cable for smaller CSA.

The trouble with Alu was

1. It is not a good a conductor as copper so it needed to be larger in CSA and on big cables it was a nightmare.

2. Termination needed to be adreessed at it often reacted to the brass in terminals and had to be treated or lugged.

I think the HV side of things still use Alu, but very few designers ask for it today and I don't think I would .

The HV supplies from the DNO's to new transformers are done in Alu.

It’s very much out of favour now due to problems with the concentric earth and neutral getting damaged. There’s very few manufacturers now making it. http://www.batt.co.uk/products/view/610/Split-Concentric-Cable-BS7870
