IEC 61914:2009

Cable cleats for electrical installations

IEC 61914:2009 specifies requirements and tests for cable cleats and intermediate restraints used for securing cable in electrical installations. Cable cleats provide resistance to electromechanical forces where declared. This standard includes cable cleats that rely on a mounting surface specified by the manufacturer for axial and/or lateral retention of cables.

Brides de câbles pour installations électriques

La CEI 61914:2009 spécifie les exigences et essais pour brides de câbles et dispositifs intermédiaires de tenue utilisés pour la fixation de câble dans les installations électriques. Les brides de câble fournissent une résistance aux forces électromécaniques, lorsque cela est déclaré. Cette norme inclut les brides de câble qui reposent sur une surface de montage spécifiée par le fabricant pour le maintien axial et/ou latéral des câbles.
