European foreword
This document (HD 361 S4:2020) has been prepared by CLC/TC 20 “Electric cables”.
The following dates are fixed:
• latest date by which this document has (dop) 2021-08-31
to be implemented at national level by
publication of an identical national
standard or by endorsement
• latest date by which the national (dow) 2023-08-31
standards conflicting with this document
have to be withdrawn
This document supersedes HD 361 S3:1999 and all of its amendments and corrigenda (if any).
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. CENELEC shall not be held responsible for identifying any or all such patent rights.
Introduction
HD 361 was adopted by CENELEC on 18 November 1976. A second edition was published in 1986. The third
edition (1999) restricted the rated voltage of cables covered by this HD to an upper limit of 450/750V, and to
harmonized cables and cords or Recognized National Types (RNT).
This fourth edition incorporates amendment HD 361 S3:1999/A1:2006 to HD 361 S3:1999, which recognized
the discontinuation of the system of RNT, and expands the cable types to include EN 50618 and EN 50620.
The incorporation of the former raises the upper voltage limit to 1000/1000 V.
1 Scope
This document details a designation system for harmonized power cables and cords according to EN 50525
(series), EN 50214, EN 50618 and EN 50620.
NOTE The use of the system for Recognized National Types of cable or cord has been withdrawn by CLC/TC 20. For
non-harmonized cables, National Committees are permitted to use any designation that does not conflict with this HD, but
see Tables 2 and 4 for recommendations.
2 Normative references
The following documents are referred to in the text in such a way that some or all of their content constitutes
requirements of this document. For dated references, only the edition cited applies. For undated references,
the latest edition of the referenced document (including any amendments) applies.

4 Basic elements of the designation
The cable designation shall be composed of three parts indicating the essential characteristics of a cable
(Table 1).
Table 1 — Basic elements of the cable description
Part Basic elements of the description See Table(s)
1 Relationship to Standards 2
Rated voltage 3
2 Construction of the cable, generally in a radial sequence and 4 to 7
starting with the insulation material; then after a dash,
Material and form of conductor(s) 8 and 9
3 Number and size of conductors 10
Part 1 and Part 2 of the designation are generally written without a space and constitute the « type designation »
of a cable or cord.
Part 3 of the designation constitutes specific information on the number and size of conductors, when required.
A survey of symbols and their sequence in the cable designation is given in Clause 8.
5 Part 1 of the Designation
Part 1 of the designation covers the relationship to standards and the rated voltages. The details are given in
Table 2 and Table 3
Table 2 — Relationship to standards
Symbol Relationship of cable to standards
H Cable conforming with harmonized standards
– Non-harmonized cable
National Committees may use any symbol or system that does not conflict with HD 361. If
the system laid down by HD 361 is used for non-harmonized cables, it is recommended
not to use a prefix symbol.
