22、hoice and installation of electrical cables 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

23、 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 Public

24、ation(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. IE

25、C 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 op

26、inion 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

27、 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 transparent

28、ly 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 provides no marking procedure to indicate its approval and cannot be rende

29、red responsible for any equipment declared to be in conformity with an IEC Publication. 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 it

30、s 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 oth

31、er 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

32、 subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 60092-352 has been prepared by subcommittee 18A: Cables and cable installations, of IEC technical committee TC 18: Electrical installations of ships and of mobile an

33、d fixed offshore units. This third edition cancels and replaces the second edition published in 1997, of which it constitutes a technical revision. Main changes with respect to the second edition relate to: sizes of earth continuity conductors and equipment earthing connections; bending radii for ca

34、bles rated at 3,6/6,0 (7,2) kV and above; current carrying capacities in amperes at core temperatures of 70 C and 90 C; tabulated current carrying capacities defined installations. 60092-352 IEC:2005(E) 5 The text of this standard is based on the following documents: FDIS Report on voting 18A/277/FD

45、e offshore units, incorporating good practice and co-ordinating as far as possible existing rules. These standards form: a code of practical interpretation and amplification of the requirements of the International Convention on Safety of Life at Sea; a guide for future regulations which may be prep

46、ared and a statement of practice for use by owners and builders of ships and fixed or mobile and offshore units and other appropriate organisations. This revision of IEC 60092-352 has been prepared by Maintenance Team 1 of IEC SC 18A, to update and include developments identified in other parts of t

47、he 60092 series of standards applicable to electric cables for electrical installations in ships, viz: the increase in maximum rated conductor temperature during normal operation for EPR, XLPE type insulations see IEC 60092-351 and the effect on current carrying capacities; the publication of IEC 60

48、092-376 covering cables for control and instrumentation 150/250V(300V); changes in test methods to demonstrate the capability of cables to continue to operate in fire conditions and to limit the spread of flame; the inclusion of a method for the determination of current carrying capacities based upo

49、n those that have been accepted and established in other applications of cable use. This method has been derived from a technical basis and allows a greater choice of use in different installation methods as opposed to that currently specified, which was established from experimental data on a limited number of cables and installation informatio
