Electrical installations in ships - Part 353: Power cables for rated voltages 1 kV and 3 kV

IEC 60092-353:2011 is applicable to shipboard and offshore non radial field power cables with extruded solid insulation, having a voltage rating of 0,6/1 (1,2) kV and 1,8/3 (3,6) kV intended for fixed installations. Cables for use in circuits requiring resistance to fire are included. The various types of power cables are given in 5.1. The constructional requirements and test methods shall comply with those indicated in IEC 60092-350, unless otherwise specified in this standard. The object of this standard is:
- to standardize cables whose safety and reliability is ensured when they are installed in accordance with the requirements of IEC 60092-352 or IEC 61892-4;
- to lay down standard manufacturing requirements and characteristics of such cables directly or indirectly bearing on safety;
- to specify test methods for checking conformity with those requirements.
This edition includes the following significant technical changes with respect to the previous edition:
a) Rationalization of the number of insulating and sheathing materials. In particular polyvinyl chloride based insulation (PVC) and sheath (ST1) have been removed. PVC sheath ST2 is permitted even though it releases harmful fumes under fire conditions;
b) Modification of construction requirements in line with IEC 60092-350;
c) Requirements and test methods have been divided in several tables for clarification. Requirements for enhanced cold properties, oil resistance and resistance to drilling fluids have been aligned to IEC 60092-350;
d) The new testing methods for fire resistant cables are referenced in the standard.

Installations électriques à bord des navires - Partie 353: Câbles d'énergie pour les tensions assignées 1 kV et 3 kV

La CEI 60092-353:2011 est applicable aux câbles pour installations à bord des navires et à champ non radial, à isolement massif extrudé, pour tension assignée 0,6/1 (1,2) kV et 1,8/3 (3,6) kV destinés aux installations fixes. Les câbles utilisés dans les circuits devant résister au feu sont inclus. Les différents types de câbles d'énergie sont indiqués en 5.1. Leurs exigences de fabrication et leurs méthodes d'essai doivent être conformes à celles qui sont indiquées dans la CEI 60092-350 sauf spécification contraire dans la présente norme. L'objet de la présente norme est:
- de normaliser des câbles qui soient sûrs et fiables lorsqu'ils sont installés conformément aux exigences de la CEI 60092-352 ou de la CEI 61892-4;
- d'établir les caractéristiques pour de tels câbles et les exigences normalisées relatives à leur fabrication se référant directement ou indirectement à la sécurité;
- de préciser les méthodes d'essai pour vérifier la conformité à ces exigences.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) Rationalisation du nombre de matériaux d'isolation et de gainage. En particulier, l'isolation à base de PVC (polychlorure de vinyle) et la gaine (ST1) ont été supprimées. La gaine ST2 en PVC est autorisée même si elle diffuse des fumées nocives en cas d'incendie;
b) Modification des exigences de construction en accord avec la CEI 60092-350;
c) Les exigences et méthodes d'essai ont été séparées pour des raisons de clarification dans plusieurs tableaux. Les exigences en matière de propriétés à froid améliorées, de résistance à l'huile et de résistance aux boues de forage ont été alignées sur celles de la CEI 60092-350;

ELECTRICAL INSTALLATIONS IN SHIPS –

Part 353: Power cables for rated voltages 1 kV and 3 kV


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 60092-353 has been prepared by Subcommittee 18A: Electric
cables for ships and mobile and fixed offshore units of IEC Technical Committee 18: Electrical
installations of ships and of mobile and fixed offshore units.
This third edition cancels and replaces the second edition published in 1995 and Amendment 1
(2001). This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) Rationalization of the number of insulating and sheathing materials. In particular polyvinyl
chloride based insulation (PVC) and sheath (ST1) have been removed. PVC sheath ST2 is
permitted even though it releases harmful fumes under fire conditions;
b) Modification of construction requirements in line with IEC 60092-350;

---------------------- Page: 6 ----------------------
60092-353 © IEC:2011 – 5 –
c) Requirements and test methods have been divided in several tables for clarification.
Requirements for enhanced cold properties, oil resistance and resistance to drilling fluids
have been aligned to IEC 60092-350;
d) The new testing methods for fire resistant cables are referenced in the standard.
The text of this standard is based on the following documents:
FDIS Report on voting
18A/316A/FDIS 18A/319/RVD

Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
A list of all the parts of the IEC 60092 series, under the general title Electrical installations in
ships, can be found on the IEC website.
The committee has decided that the contents of this publication will remain unchanged until the
stability 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
• amended.
