20、idance and to define special requirements for the design and testing of insulating synthetic ropes, their sheaths and their terminations for use in electric traction overhead contact lines. Special preferences will include such requirements as to comply with local procurement policies, working pract

21、ices, compatibility with existing systems, to combat environmental pollution and to provide a supporting assembly with insulation which will give reliable service over its target life span. These insulating synthetic ropes offer an alternative to the use of metallic cables associated with convention

22、al insulators. 1 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 railw

23、ays, tramways, trolleybuses and other systems. These insulating synthetic ropes are utilised to provide mechanical support and electrical insulation for overhead contact lines. They are generally used in the following application fields: delta suspension of contact wires; catenary cable; mid point a

24、nchors; tie; dropper; headspan; noise and vibration damper; bridle- and pulley suspensions; cantilevers made of glass reinforced polymer (GRP). This standard establishes the product characteristics, the test methods and checking procedures to be used with the insulating synthetic ropes, together wit

25、h 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.

34、bination 4 Characteristics of the rope 4.1 General 4.1.1 Common characteristics Two major fibre types are used actually to provide the load carrying core. These are polyester and polyaramid. Other fibre types having similar characteristics may also be used. The fibre type is important in determining

35、 mechanical properties. The sheath polymer type is important in determining durability, environmental performance and some electrical and mechanical properties. 4.1.2 Specific characteristics of core materials Insulating synthetic ropes with polyaramid or similar core fibres have a smaller diameter,

36、 greater tensile fatigue resistance and smaller elongation (see B.1.1) than those of polyester or similar core fibres for a given load carrying capacity and axial stiffness. Insulating synthetic ropes with polyester or similar core fibres have a higher impact resistance than those of polyaramid or s

37、imilar core fibres, for example: from detached trolleybus poles. Insulating synthetic ropes can operate within the following operational environmental temperatures: between 40 C and +55 C for polyester or similar; between 40 C and +80 C for polyaramid or similar. 4.1.3 Specific characteristics of sh

38、eath materials The sheath may be composed of different materials. The type of material shall be chosen to withstand local conditions as: U.V. exposure (e.g. polyethylene); general environmental conditions (e.g. polyethylene); abrasion effects (e.g. polyester / elastomer); flex effects (e.g. polyeste

39、r / elastomer). BS EN 50345:2009EN 50345:2009 - 8 - When the rope is used in confined spaces (e.g. tunnels, stations, etc.) the sheath material shall have further properties as: electrical tracking resistance (e.g. crosslinked polyethylene); antiflammability (e.g. crosslinked polyethylene); self-ext

40、inguishing (e.g. crosslinked polyethylene). 4.2 Client requirements The client shall provide a comprehensive and specific description of the overhead contact line service parameters and functioning requirements which may affect the design of the insulated synthetic rope. This shall include, as appro

41、priate, but not be limited to the following: electrical system service parameters; spatial and dimensional parameters; angular movement deflection limitations; maximum working loads required; environmental conditions; end fittings connection (terminations) requirements; any additional requirement fo

42、r special tests; any special delivery or packaging requirements; identification of inspection and tests to be witnessed by the purchaser; service life of the insulator. 4.3 Electrical requirements 4.3.1 Voltages Values of voltages are shown in Table 1. The rated insulation voltage and the test volta

43、ge levels are based on statistical and risk consideration, which may affect the insulator during its service life.

Consideration shall also be given to the type of insulating synthetic rope and its behaviour in polluted conditions related to the whole life of the equipment. The minimum creepage distance, for nominal voltages equal

46、 to or below 1,5 kV d.c. or 1 kV a.c. shall be 1 m. NOTE This distance is based on practical experience. For nominal voltages exceeding 1,5 kV d.c. or 1 kV a.c., an additional creepage distance per extra kV of the nominal voltage shall be calculated from Table 2 and added to the minimum creepage dis

47、tance. EXAMPLE A 25 kV a.c. system with 45 inclination with no waterproof termination and for extreme unfavourable conditions requires a total creepage distance of 3 040 mm.

49、eement between purchaser and supplier. The creepage distance values for nominal voltage up to 1,5 kV d.c. are valid for double insulation.
