This part of IEC 60502 specifies the construction, dimensions and test requirements of power cables with extruded solid insulation for rated AC voltages of 1 kV (U = 1,2 kV) and 3 kV m (U m = 3,6 kV) for fixed installations such as distribution networks or industrial installations.
Cables of rated AC voltage 1 kV (U = 1,2 kV) designed and tested in accordance with this m document can also be used, if declared by the manufacturer, in DC distribution systems having their nominal voltage ≤ 750 V DC (with a maximum of 900 V DC) between a live conductor and neutral/earth , or ≤ 1 500 V DC (with a maximum 1 800 V DC) between two live conductors. Applicable core identification for DC systems are considered in accordance with local installation regulations.
