FOREWORD

This Harmonization Document was prepared by WG 9 of the Technical Committee CENELEC TC 20,
Electric cables.

The text of the draft was submitted to the Unique Acceptance Procedure and was approved by CENELEC
as HD 632 S2 on 2008-10-01.

This Harmonization Document supersedes HD 632 S1:1998 + corrigendum November 1998 and its
amendment A1:2002.

By comparison with the S1 version, this full revision of HD 632:

- uses IEC 60840, Ed 3, 2004, as its Part 1;
- amends Part 2 “Additional test methods” accordingly;
- revises the particular sections in Parts 3-11 inclusive in one of three ways, namely:

a) by presenting a fully updated section;
b) by indicating only those requirements that differ from, or add to, those of Part 1;
c) by withdrawing the section.

The consequential parts and particular sections are listed hereafter. In respect of the particular sections in
Parts 3 to 11, and by decision of the Technical Board (D68/047), National Committees need only
implement those sections having national applicability. The obligation remains however to announce the
full HD in public by titles and numbers, and also to withdraw any conflicting national standards.

Page numbering reflects the arrangements into Parts and Particular sections, e.g. Page 4-C-3 is page 3
of particular Section C of Part 4.

References to other HDs, ENs and international standards are given in the particular parts or sections.

By decision of the Technical Board (D81/139 extended by D104/118 & D114/076) this HD exists only in
English.

The following dates were fixed:


– latest date by which the existence of the HD
(doa) 2009-04-01
has to be announced at national level

– latest date by which the HD has to be implemented

at national level by publication of a harmonized
(dop) 2009-10-01
national standard or by endorsement

– latest date by which the national standards conflicting
(dow) 2011-10-01
with the HD have to be withdrawn

POWER CABLES WITH EXTRUDED INSULATION AND THEIR
ACCESSORIES FOR RATED VOLTAGES ABOVE 36 kV (U = 42 kV)
m
UP TO 150 kV (U = 170 kV) –
m
TEST METHODS AND REQUIREMENTS


1 Scope
This standard specifies test requirements for power cables with extruded insulation, of the
types listed in Table 1, and their accessories, of rated voltage, U, above 36 kV (U = 42 kV) up
m
to and including 150 kV (U = 170 kV), for fixed installations intended for transmission and
m
distribution systems, and for use in power generating plants and sub-stations.
Depending on the design and the system conditions, additional or even fewer tests or other
requirements which are not described in the Part 1 can be specified in the particular sections of
Parts 3 to 11.
In these parts each section is either:
1) A full tabulation showing how the particular section either agrees, or deviates from,
each clause of Part 1; or
2) A reduced tabulation showing only those places where the particular section deviates
from Part 1.
The requirements apply to single-core cables and three-core cables with separate cores and to
their accessories for usual conditions of installation and operation, but not to special cables
and their accessories, such as those designed for submarine cables, for which modification to
the standard tests may be necessary or special test conditions may need to be devised.
This standard does not cover transition joints between cables with extruded insulation and
paper insulated cables.

For the purposes of this document, the following definitions apply.
3.1 Definitions of dimensional values (thicknesses, cross-sections, etc.)
3.1.1
nominal value
value by which a quantity is designated and which is often used in tables
NOTE Usually, in this standard, nominal values give rise to values to be checked by measurements taking into
account specified tolerances.
3.1.2
median value
when several test results have been obtained and ordered in an increasing (or decreasing)
succession, middle value if the number of available values is odd, and mean of the two middle
values if the number is even
3.2 Definitions concerning the tests
3.2.1
routine tests
tests made by the manufacturer on each manufactured component (length of cable or
accessory) to check that the component meets the specified requirements
3.2.2
sample tests
tests made by the manufacturer on samples of completed cable or components taken from a
completed cable or accessory, at a specified frequency, so as to verify that the finished product
meets the specified requirements
3.2.3
type tests
tests made before supplying on a general commercial basis a type of cable system or cable or
accessory covered by this standard, in order to demonstrate satisfactory performance
characteristics to meet the intended application. Once successfully completed, these tests
need not be repeated, unless changes are made in the cable or accessory materials, or design
or manufacturing process which might change the performance characteristics

4 Voltage designations and materials
4.1 Rated voltages
In this standard, the symbols U , U and U are used to designate the rated voltages of cables
0 m
and accessories where these symbols have the meanings given in IEC 60183.
4.2 Cable insulating materials
This standard applies to cables insulated with one of the materials listed in Table 1. It also
specifies for each type of insulating compound the maximum operating conductor temperatures
on which the specified test conditions are based.
4.3 Cable oversheathing materials
Tests are specified for four types of oversheath, as follows:
– ST and ST based on polyvinyl chloride;
1 2
– ST and ST based on polyethylene.
3 7
The choice of the type of oversheath depends on the design of the cable and the mechanical
and thermal constraints during installation and operation.
The maximum conductor temperatures in normal operation for the different types of
oversheathing materials covered by this standard are given in Table 2.
5 Precautions against water penetration in cables
When cable systems are installed in ground, easily flooded galleries or water, a radial water
impermeable barrier around the cable is recommended.
NOTE A test for radial water penetration is not currently available.
Longitudinal water barriers may also be applied to avoid the need to replace long sections of
cable in case of damage in the presence of water.
A test for longitudinal water penetration is given in 12.4.18.
