Al Cables vs Cu Cables Comparison - Technical and Economical

[Joao]

Do you have some data that you can share for EHV, HV. MV and LV cables.

In my opinion as GENERAL the cost will be more less the same as Cu or Al, since the supply cost is less but erection is higher. So more less will be same same.

Here in America, aluminum is the lowest cost in almost all cases. But I don't like it for LV smaller than #4 AWG (21.2 mm²).

I believe everything in EHV and HV is predominantly overhead aluminum.
