IEC 60502-1 and 60502-2 are 2 standards for ?Power cables with extruded insulation
and their accessories?-60502-1 for low-voltage cables and 60502-2 for medium voltage cables.
IEC 60287-2-1 Electric cables ?Calculation of the current rating ?Thermal resistance ?Calculation of thermal resistance.
They are many correction factors.
If you would be more specific you could get an advice, I guess.
