IEC 61084-1:2017

Cable trunking systems and cable ducting systems for electrical installations - Part 1: General requirements

IEC 61084-1:2017 specifies requirements and tests for cable trunking systems (CTS) and cable ducting systems (CDS) intended for the accommodation, and where necessary for the electrically protective separation, of insulated conductors, cables and possibly other electrical equipment in electrical and/or communication systems installations. The maximum voltage of these installations is 1 000 V AC and 1 500 V DC.
This document does not apply to conduit systems, cable tray systems, cable ladder systems, power track systems or equipment covered by other standards.
This second edition cancels and replaces the first edition published in 1991 and Amendment 1:1993. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
- classification;
- construction;
- mechanical and electrical properties.
This part of the IEC 61084 series is not intended to be used by itself.

Systèmes de goulottes et systèmes de conduits-profilés pour installations électriques - Partie 1: Exigences générales

L'IEC 61084-1:2017 spécifie les exigences et les essais pour les systèmes de goulottes (SG) et les systèmes de conduits-profilés (SCP) destinés au logement de conducteurs isolés, câbles et éventuels autres équipements électriques et, si nécessaire, à leur séparation de protection électrique, dans des installations électriques et/ou de systèmes de communication. La tension maximale de ces installations est de 1 000 V en courant alternatif et 1 500 V en courant continu.
Le présent document ne s’applique pas aux systèmes de conduits, systèmes de chemins de câbles, systèmes d’échelles à câble, systèmes de canalisations préfabriquées ou aux équipements couverts par d’autres normes.
Cette deuxième édition annule et remplace la première édition parue en 1991 et l'Amendement 1:1993. Cette édition constitue une révision technique.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
- classification;
- construction;
- propriétés mécaniques et propriétés électriques.
La présente partie de la série IEC 61084 n’est pas destinée à être utilisée seule.
