(Main)Overhead distribution cables of rated voltage U0/U(Um): 0,6/1 (1,2) kV
Overhead distribution cables of rated voltage U0/U(Um): 0,6/1 (1,2) kV
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.

Part 1
76 Introduction
77 This edition has been prepared to cover the latest market requests on overhead distribution cables of rated
78 voltage Uo/U(Um): 0,6/1 (1,2) kV. Since the publication of the first edition in 1996 and the amendments in 1997
79 and 2002, a number of particular sections have been withdrawn, new sections have been added from countries
80 not covered in the first edition, technical improvements have been added and a number references to test
81 method standards were updated. The Table of Content indicates even the withdrawn sections.
82 Part 1 of this document contains the General Requirements applicable to cables for overhead distribution and
83 service, specified in the particular sections of Parts 3 to 10. In general, bundle assembled cores are specified.
84 Single core cables are specified in Part 9.
85 The document contains the following Parts, arranged according to the main constructional features of the cables
86 covered:
87 HD 626 Part 1 General Requirements
88 HD 626 Part 2 Additional Test Methods
89 HD 626 Part 3 PE insulated self-suppor
