Articulated systems and flexible systems for cable guiding

IEC 62549:2011 specifies requirements and tests for systems with adaptable linear geometry for cable guiding intended for the accommodation and retention of cables and possibly other electrical equipment in electrical and/or communication systems installations. The maximum voltage of these installations is 1 000 V a.c. and 1 500 V d.c. This standard does not apply to cable trunking systems, cable ducting systems, conduit systems, cable tray systems, cable ladder systems, powertrack systems, energy conveying chains or equipment covered by other standards. The contents of the interpretation sheet 1 of October 2015 have been included in this copy.

Systèmes articulés et souples pour guidage de câbles

La CEI 62549:2011 spécifie les exigences et les essais relatifs aux systèmes de guidage de câbles à géométrie longitudinale adaptable destinés au logement et à la retenue des câbles et éventuels autres équipements électriques 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. La présente Norme ne s'applique pas aux systèmes de goulottes, systèmes de conduits-profilés, systèmes de conduits, systèmes de chemins de câbles, systèmes d'échelles à câbles, systèmes de conducteurs préfabriqués, aux chaînes de transport d'énergie ou aux équipements couverts par d'autres normes. Le contenu de la feuille d'interprétation 1 d'octobre 2015 a été pris en considération dans cet exemplaire.
