Overhead distribution cables of rated voltage U0/U(Um): 0,6/1 (1,2) kV HD 626-S2:2025

Publication date:   Nov 18, 2025

Scope

HD 626 applies to cables of rated voltage U0/U(Um) = 0,6/1(1,2) kV used in overhead power distribution systems mainly for public distribution, of maximum system voltage not exceeding 1,2 kV. This part (Part 1) specifies the general requirements applicable to these cables, unless otherwise specified in the particular sections of this HD.
The objects of this Harmonisation Document are:
- to standardize cables that are safe and reliable when properly used and equipped with appropriate accessories, in relation to the technical requirements of the system of which they form a part,
- to state the characteristics and manufacturing requirements which have a direct or indirect bearing on safety,
- and to specify methods for checking conformity with those requirements.
