MS IEC 60502-1:2021 Power cables with extruded insulation and their accessories for rated voltages from 1 kV (Um = 1,2 kV) up to 30 kV (Um = 36 kV) — Part 1: Cables for rated voltages of 1 kV (Um = 1,2 kV) and 3 kV (Um = 3,6 kV)

Scope:

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 in accordance with this
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.
