It is therefore essential that a high level of safety is achieved, even when fail
22、ures occur which may involve fire, howsoevercaused, affecting railway rolling stock.Hence it is necessary to provide cables for use in railway environments which minimise the hazard to people when a fire may damage the cable, irrespective of whether the fire is caused by an external source or fromwi
23、thin the electrical system. EN 50382 specifies cables for power and associated circuits which, in the event of fire, will limit the risk to people and improve the safety on railways in general. It coverscables, foruse in railway rolling stock, and having standard wall thickness of insulation, based
24、on materials that allow them to operate at high temperature and which are also halogen free. In the event of a fire affecting cables to EN 50382 they will have a limited flame spread and limited emission of toxic gases. In addition these cables when burnt produce limited amounts of smoke. This last
25、characteristic will minimise loss of visibility in the event of a fire and will aid reduced evacuation times.The objects of this standard are to standardise cables that are safe and reliable when properly used, to state the characteristics, performance, and construction requirements directly or indi
26、rectlybearing on safety, to specify methods for checking conformity with these requirements.EN 50382, which covers a range of cables rated at up to 3,6/6 kV with conductor sizes1,5 mm up to 400 mm, is divided into 2 parts: Part 1: General requirements; Part 2: Single core silicone rubber insulated c
27、ables for 120 C or 150 C. These cables are intended for a limited number of applications. Information regarding selection and installation of cables including current ratings can be found in EN 50355 and EN 50343. The procedure for selection of cable cross-sectional area, including reduction factors
28、forambient temperature and installation type, are described in EN 50343. NOTE Current ratings for inclusion in EN 50355 are under development for the next amendment.Special test methods referred to in EN 50382 are given in EN 50305.

29、 - 4 - 5 EN 50382-1:2008 1 Scope This Part1 of EN 50382 specifies the general requirements applicable to the cables given in EN 50382-2. It includes the detailed requirements for the insulating and sheathing materials and other components called up in EN 50382-2. In particular EN 50382-1 specifies t
30、hose requirements relating to fire safety. Based on proven experience and reliability over many years these cables are rated foroccasional thermal stressescausing ageing equivalent to continuous operational life at a conductor temperature of either 120 C or 150 C. NOTE This rating is based upon the
31、polymer defined in 3.1. Before this polymer had gained widespread acceptance in the cable industry, ageing performance had been assessed via long term thermalendurance testing and had been extrapolated to 20 000 h using techniques equivalent to those in EN60216. Subsequent experience in service has
32、demonstrated that the predicted performance levelswere correct.Where extrapolated data is used to predict lifetime in service it should be confirmed with the cable manufacturer, and should be based on a failure mode appropriate to the type of material or cable.The maximum temperature for short circu
33、it conditions for silicone rubber is 350 C based on a duration of 5 s.Although both of the insulating and one of the sheathing compounds specified in this standard are thermallycapable of operating at 150 C, where tinned conductors are used the maximum operating temperature islimited to 120 C and fo
34、r the same technical reason the maximum short circuit temperature, for tinned copperconductors, is limited to 250 C. The choice of sheath may also limit the operating temperature to 120 C.
