I see, my 10mm2 cable says " single insulated extra flexible Resistant to petrol, lubricating oils and diluted acids. Plain copper conductors - PVC insulated -30°C (-22F) - 70°C (158F)."Depends on insulation (voltage rating, temperature rating, flammability rating, water resistance, UV resistance)
So "cable" is not just "cable"
For example "AJ" or "FLY" cable is only rated for max 75 volts
10mm2 is roughly equivalent to 8 awg.
The problem is your wire doesn't have a voltage rating on the jacket.
BTW, I googled your quoted text and got 0 hits.
IMHO the problem is the voltage rating is not on the jacket.So the jacket is the problem then?
Someone please explain amateur user why I can't use 8awg /10mm2 copper wire for 110v/240v with 10-15amps in average. Is the PVC coating problem? But I have seen the exact same PVC coating used in commercial and home appliances.
Jacket not having voltage rating or approval markings is first problem. Secondly 10mm2 cable is actually too big to fit in lots of the 120/240V hardware(light switches, wall sockets etc typically fit max 2.5mm2 wire)So the jacket is the problem then?

What is the voltage rating for the wire?
I agree my question in general if I can use 10mm2 for higher voltage. In other hand jacket rating is something to do with pvc coating issue or actual copper?

Jacket rating and lack of approvalsfor the jacket is the problem.You are going in the wrong direction I think.
I try to figure out why copper wire cannot be used for high or low voltage applications?
The same copper that used everywhere or not, perhaps there is a chosen copper that deserves a higher voltage rating? And if no rating is bad and ugly copper?

Copper is the same and even much larger sizes than 10mm2 are used in high power installations. 63A 230V circuit might require 25mm^2 copper
So you recon that if I choose higher voltage rated cable I can use same cable for low voltage applications?The rating of the jacket makes a huge difference. There is #8 landscape wire rated at 150vac and #8 l824 aviation wire rated at 5,000 volts.
Voltage is pressure, so just as water pipes are made of different materials that can handle different pressure and temp ratings before bursting, so is the wire.
