Railway applications - Fixed installations - Electric traction overhead contact lines

This document applies to overhead contact line systems in heavy railways, light railways, trolley buses and industrial railways of public and private operators. This document applies to new installations of overhead contact line systems and for the complete renewal of existing overhead contact line systems. This document contains the requirements and tests for the design of overhead contact lines, requirements for structures and their structural calculations and verifications as well as the requirements and tests for the design of assemblies and individual parts. This document does not provide requirements for ground level conductor rail systems (see Figure 1).

Applications ferroviaires - Installations fixes - Lignes aériennes de contact pour la traction électrique

La présente Norme européenne s'applique aux lignes aériennes de contact de traction électrique des réseaux ferrés lourds et légers, des trolleybus ainsi qu'aux réseaux industriels (publics ou privés). La présente norme s'applique aux nouvelles constructions de lignes aériennes de contact, ainsi qu'à la rénovation de portions de lignes existantes. La présente norme spécifie les exigences et les essais pour la conception des lignes aériennes de contact, les exigences relatives aux structures, leurs calculs et vérifications, ainsi que les exigences et les essais pour la conception des ensembles et des parties individuelles. La présente norme ne spécifie pas les exigences pour les systèmes à rail de contact lorsque les rails de contact sont situés à proximité des rails de roulement.
