scope:

This European Standard applies to the insulating synthetic ropes used in overhead contact lines. This European Standard specifies the characteristics of insulating synthetic rope assemblies and is applicable to electric traction overhead contact lines for railways, light railways, tramways, trolleybuses and other systems. These insulating synthetic ropes are utilised to provide mechanical support and electrical isolation for overhead contact lines. They are generally used in the following application fields: delta suspension of contact wires; catenary cable; mid point anchoring; tie; dropper; headspan; noise and vibration damper; bridle- and pulley suspensions; cantilevers made of glass reinforced plastic (GRP). This standard establishes the product characteristics, the test methods, checking procedures to be used with the insulating synthetic ropes, together with the ordering and delivery requirements. The object of this standard is to stipulate the provisions for the design and to allow the provisions of the service indicated by the supplier to the purchaser or informed buyer.
