(Main)Electrical installations in ships - Part 350: General construction and test methods of power, control and instrumentation cables for shipboard and offshore applications
Electrical installations in ships - Part 350: General construction and test methods of power, control and instrumentation cables for shipboard and offshore applications
IEC 60092-350:2020 provides the general constructional requirements and test methods for use in the manufacture of electric power, control and instrumentation cables with copper conductors intended for fixed electrical systems at voltages up to and including 18/30(36) kV on board ships and offshore (mobile and fixed) units.
The reference to fixed systems includes those that are subjected to vibration (due to the movement of the ship or installation) or movement (due to motion of the ship or installation) and not to those that are intended for frequent flexing. Cables suitable for frequent or continual flexing use are detailed in other IEC standards, for example IEC 60227 (all parts) and IEC 60245 (all parts), and their uses are restricted to those situations which do not directly involve exposure to a marine environment, for example, portable tools and domestic appliances.
The following types of cables are not included:
- optical fibre;
- sub-sea and umbilical cables;
- data and communication cables;
- coaxial cables.
This fifth edition cancels and replaces the fourth edition published in 2014 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) more detailed description of the test procedures in 7.7.6 and 7.7.7;
b) description of the relationship between Annex A and Annex D.
Installations électriques à bord des navires – Partie 350: Construction générale et méthodes d'essai des câbles d'énergie, de commande et d'instrumentation des navires et des unités mobiles et fixes en mer
L'IEC 60092-350:2020 fournit les exigences générales de construction et les méthodes d'essai à utiliser lors de la fabrication des câbles d'énergie, de commande et d'instrumentation à âmes en cuivre destinés à la connexion de systèmes électriques fixes à une tension au plus égale à 18/30(36) kV installés à bord des navires et des unités en mer (mobiles et fixes).
Les installations fixes incluent les systèmes qui sont soumis à des vibrations (sous l'action du mouvement du navire ou de l'installation) ou des mouvements (sous l'action du déplacement du navire ou de l'installation), mais pas ceux qui sont prévus pour subir des flexions fréquentes. Les câbles prévus pour subir des flexions fréquentes ou continues sont décrits dans d'autres normes IEC (IEC 60227 (toutes les parties) et IEC 60245 (toutes les parties), par exemple), et leurs utilisations se limitent à celles n'impliquant pas directement une exposition à un environnement marin (outils portatifs et appareils domestiques, par exemple).
Les types de câbles suivants ne sont pas couverts:
- câbles à fibres optiques;
- câbles sous-marins et ombilicaux;
- câbles de données et de communication;
- câbles coaxiaux.
Cette cinquième édition annule et remplace la quatrième édition parue en 2014. Cette édition constitue une révision technique.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) description plus détaillée des procédures d'essai données en 7.7.6 et 7.7.7;
b) description de la relation entre l'Annexe A et l'Annexe D.
