Standards Development
This European Standard specifies the characteristics of copper and copper alloy wires of cross sections of 80 mm², 100 mm², 107 mm², 120 mm² and 150 mm² for use on overhead contact lines. It establishes the product characteristics, the test methods, and the checking procedures to be used with the wires, together with the ordering and delivery conditions. It applies to: – railways; – guided mass transport systems, such as tramways, elevated and underground railways, mountain railways, trolleybus systems, and magnetically levitated systems which use a contact line system. This European Standard may also be applied to electrified road traffic with a contact line, such as truck-trolley systems. This European Standard applies to new electric traction systems and may be applied to changes of existing systems. It does not apply to: – underground mine traction systems; – cranes, transportable platforms and similar transportation equipment on rails, temporary structures (e.g. exhibition structures) in so far as these are not supplied directly or via transformers from the contact line system and are not endangered by the traction power supply system; – suspended cable cars; – funicular railways; – magnetic levitated systems (without a contact line system); – railways with an inductive power supply without contact system; – railways with a buried contact system that is required to be energised only below the train to ensure safety.
EN 50149:2012 needs to be amended according to the following • Add alloy CuSn 0.1; • Enhance information regarding the conductor's characteristics, chemical composition, conductivity, thermal resistance and tensile strength; • Improve alignment with table 1 of EN 50119; • Removal of Cadmium Copper Alloys in accordance with directive 2011/65/EU of the European parliament and of the council of 8 June 2011 on the restriction of the use of certain hazardous substances in electrical and electronic equipment.
