I'm sorry, I did not realize that you used nowadays aluminum.
The conductivity of aluminum is only a little over half the size of copper.
Therefore, it is so that you can take a 2.5mm² aluminum cable and the same could take a 1.5 mm² copper cable - and probably should.
At the ominous material magic to that the fact that the cable only auc 50 strands is. So it's quite pretty rigid and unsuitable for flexible applications.
In addition, when unpacking, I noticed quite a chemical smell from the insulation ago.
All in all: a cord as a makeshift, but not for a search of what reasonable. But the price is what distinguishes the cable.
