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 (Um = 1,2 kV) and 3 kV (Um  = 3,6 kV) for fixed installations such as distribution networks or industrial installations.

Cables of rated AC voltage 1 kV (Um = 1,2 kV) designed and tested according to this standard may 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 ≤1500 V DC (with a maximum 1800 V DC) between two live conductors. Applicable core identification for DC-system should be considered according to local installation regulations.

NOTE 1 Recommendation for preferred core colours for line conductors in DC systems is given in IEC 60445. However, local installation regulations for DC systems may already contain specific identification requirements.

This standard includes cables which exhibit properties of reduced flame spread, low levels of smoke emission and halogen-free gas emission when exposed to fire.

Cables for special installation and service conditions are not included, for example cables for overhead networks, the mining industry, nuclear power plants (in and around the containment area), submarine use or shipboard application, or cables directly connected to photovoltaic systems.

NOTE 2 Cables for photovoltaic systems are covered by IEC 62930.
