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)

IEC 60502-1:2021 has been prepared by IEC technical committee 20: Electric cables. It is an International Standard.

This third edition cancels and replaces the second edition published in 2004 and Amendment1:2009. This edition constitutes a technical revision.

This edition includes the following significant technical changes with respect to the previous edition:
a) references to IEC 60811 (all parts) have been updated and mechanical testing requirements specific to halogen free low-smoke oversheath of material type STg have been considered;
b) the use of the types of sheathing material to be used is now clearly defined;
c) the applicability of cables for use in DC systems is now included in the scope;
d) items which were earlier marked as “under consideration* were studied either for an appropriate solution if found available, or for removal for the time being.
