Power cables with extruded insulation and their accessories for rated voltages from 1 kV (<em>U</em>_m = 1,2 kV) up to 30 kV(<em>U</em>_m = 36 kV) - Part 1: Cables for rated voltages of 1 kV (<em>U</em>_m = 1,2 kV) and 3 kV (<em>U</em>_m = 3,6 kV)

IEC 60502-1:2004+A1:2009 specifies the construction, dimensions and test requirements of power cables with extruded solid insulation for rated voltages of 1 kV (Um = 1,2 kV) and 3 kV (Um = 3,6 kV) for fixed installations such as distribution networks or industrial installations. This standard includes cables which exhibit properties of reduced flame spread, low levels of smoke emission and halogen-free gas emission when exposed to fire. Cables for special installation and service conditions are not included, for example cables for overhead networks, the mining industry, nuclear power plants (in and around the containment area), submarine use or shipboard application. This consolidated version consists of the second edition (2004) and its amendment 1 (2009). Therefore, no need to order amendment in addition to this publication.

Câbles d'énergie à isolant extrudé et leurs accessoires pour des tensions assignées de 1 kV (<em>U</em>_m = 1,2 kV) À 30 kV (<em>U</em>_m = 36 kV) - Partie 1: Câbles de tensions assignées de 1 kV (<em>U</em>_m = 1,2 kV) et 3 kV (<em>U</em>_m = 3,6 kV)

La CEI 60502-1:2004+A1:2009 Spécifie la constitution, les dimensions et les exigences d'essais des câbles d'énergie à isolation extrudée par diélectriques massifs, de tensions assignées de 1 kV (Um = 1,2 kV) et 3 kV (Um = 3,6 kV), pour installations fixes telles que les réseaux de distribution ou les installations industrielles. La présente norme introduit des câbles qui présentent des propriétés de propagation de la flamme réduite, de faibles niveaux d'émission de fumée et des émissions de gaz sans halogène lorsqu'ils sont exposés au feu. Les câbles destinés à des conditions particulières d'installations et de service ne sont pas inclus, par exemple les câbles pour réseaux aériens, pour l'industrie minière, les centrales nucléaires (à l'intérieur et à l'extérieur de l'enceinte de confinement), les câbles sous-marins ou les câbles de bord des navires. Les modifications majeures par rapport à la première édition concernent les exigences pour les épaisseurs des enveloppes isolantes et des gaines de protection extérieures ainsi que les exigences pour les câbles sans halogène avec des propriétés de propagation de la flamme réduites et de faibles niveaux d'émission de fumée.  Cette version consolidée comprend la deuxième édition (2004) et son amendement 1 (2009). Il n'est donc pas nécessaire de commander l'amendement avec cette publication.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60502-1 has been prepared by IEC technical committee 20: Electric
cables.
This consolidated version of IEC 60502-1 consists of the second edition (2004) [documents
20/683/FDIS and 20/691/RVD] and its amendment 1 (2009) [documents 20/1063/FDIS and
20/1069/RVD].
The technical content is therefore identical to the base edition and its amendment and has
been prepared for user convenience.
It bears the edition number 2.1.
A vertical line in the margin shows where the base publication has been modified by
amendment 1.

The main changes with respect to the first edition relate to insulation and oversheath thickness
requirements, and inclusion of constructions and requirements for halogen free cables with
reduced flame propagation and low levels of smoke emission.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
IEC 60502 consists of the following parts, under the general title Power cables with extruded
insulation and their accessories for rated voltages from 1 kV (U = 1,2 kV) up to 30 kV

The committee has decided that the contents of the base publication and its amendments will
remain unchanged until the maintenance result date indicated on the IEC web site under
"http://webstore.iec.ch" in the data related to the specific publication. At this date,
the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
