铝合金电缆欧洲标准

铝合金电缆欧洲标准

欧洲标准的铝合金电缆主要参考EN AB-43300。

EN AB-43300是一种铝合金导体,其化学成分如下:
- Si:9~10%
- Fe:0.15%
- Cu:0.03%
- Mn:0.1%
- Mg:0.3~0.45%
- Zn:0.07%
- Ti:0.15%
与纯铝导体相比,EN AB-43300铝合金导体在导电性能、抗蠕变性能、弯曲性能和耐腐蚀性能等方面具有更好的性能。

此外,铝合金电缆的重量约为铜电缆的一半,从而降低了电缆的重量、安装成本,以及设备和电缆的磨损。

在欧洲市场上,CE标志是一种安全性认证证书,表示产品符合欧洲安全标准。

贴有CE 标志的电缆产品可以在欧盟国家范围内自由流通。

在选择欧洲标准的铝合金电缆时,请确保产品符合EN AB-43300标准,并已获得CE认证。

高速铁路动车组用电线电缆绝缘和护套资料的特殊要求

高速铁路动车组用电线电缆绝缘和护套资料的特殊要求

高速铁路动车组用电线电缆绝缘和护套材料的特殊要求高速铁路动车组机车内的特定使用环境对电缆的性能要求比较苛刻,要求电缆应具有电气的可靠性、运行的安全性、耐热性、低烟无卤阻燃性能,以及无毒、无石棉、耐油、耐盐雾腐蚀等性能。

目前高速铁路机车车辆电缆的制造标准有中国铁标(主要参照欧标)TB/T 1484-2010 额定电压3kV及以下标准壁厚绝缘电缆系列,欧洲标准EN 50264:2008铁路设施—具有特殊防火性能的铁路机车车辆动力和控制电缆系列,EN 50306:2002铁路设施-具有特殊防火性能的轨道车辆电缆—薄壁系列,以及日本标准JIS C系列标准。

根据中国铁标、欧洲标准以及日本标准,时速500km动车组用电线电缆包括标准壁厚和薄壁两大种类以及各自对应的单芯和多芯结构。

南车青岛四方机车车辆股份有限公司采用日标系列,其标准要求较高,目前国内没有相应的绝缘材料能够满足,而日方控制绝缘材料的使用,肆意提高材料价格,大大增加了该系列产品的生产制造成本。

中国北车大同机车车辆有限公司和中国北车长春轨道客车股份有限公司均采用欧洲系列标准制造,由于该标准要求高,制造难度大,我公司在接到技术协议后仍然不能按照技术要求生产。

时速350km以下均采用国内铁标标准生产,而时速350km及以上均采用日标或欧标标准,具体指标如下:表1 TB/T 1484-2010标准主要检查项目与技术要求检验项目技术要求断裂伸长率≥150%耐臭氧试验电缆的绝缘、单绝缘在臭氧容积浓度为0.025%~0.030%之间的空气内放置3h 后应无裂纹,并经受浸水后电压试验无击穿。

中欧轨道交通机车用电线电缆防火性能的标准比对

标准比对中欧轨道交通机车用电线电缆防火性能的标准比对■ 万修芹1,2 刘驰宇1,2 刘 博1,2 吴莉莉1,2 孔高祥1,2 于虎娜1〔1. 山东省产品质量检验研究院;2. 国家消防及阻燃产品质量检验检测中心(山东)〕摘 要:随着轨道交通建设的不断推进,轨道交通机车用电线电缆的防火性能成为关注焦点。

本文以国际标准EN 45545-2:2020和国内相关标准(如GB/T 12528-2008、GB/T 19666-2019、TB/T 1484系列标准)为比对基准,从测试项目、测试方法和指标要求等方面对轨道交通机车用电线电缆防火性能进行了分析。

结果表明,我国标准未明确防火等级划分,相比EN 45545-2:2020,我国标准对性能指标要求相同或更高;在测试项目和方法上,国内外标准基本一致,但在产烟毒性测试方法上存在差异。

建议我国标准修订加强防火等级划分和规范,促进与国际标准接轨,推动我国轨道交通机车用材料的规范化和标准化发展。

This paper conducts an analysis of the fi reproof performance of wires and cables for rail locomotives, comparing international standard EN 45545-2:2020 and relevant Chinese standards (such as GB/T 12528-2008, GB/T 19666-2019 and TB/T 1484 series), from the aspects of testing projects, testing methods, and indicators. The key fi ndings are as follows: Chinese standards lack of a clear fi reproof grading system; standards in China have the same or higher requirements, compared to EN 45545-2:2020; standards at home and abroad are basically the same in terms of testing projects and methods, but are different in the testing method for smoke toxicity. The paper proposes the revision of Chinese standards to enhance the grading and regulation of fi re resistance, promote alignment with international standards, and boost the standardized development of materials for rail locomotives in China.Keywords: rail traffi c, locomotive, wire and cable, fi re resistance, standard comparison0 引 言当今轨道交通建设已经成为基础建设的重要组成部分,建成后的轨道交通将极大提高城市通勤上限,提升城市通勤效率,稳定、安全、可靠的轨道交通机车是社会和人民关注的重点。

欧标耐油电缆等级划分

欧标耐油电缆等级划分

在欧洲标准(EN)中,耐油电缆通常按照其能够承受的油类型和温度等级进行分类。

电缆的耐油性能主要取决于绝缘材料和护套材料的选择,这些材料需要能够抵抗油品的化学侵蚀以及高温环境下的热稳定性。

耐油电缆的等级划分通常涉及以下方面:
1. 油类型:电缆必须能够适应不同类型的油,如矿物油、植物油、变压器油等。

每种油类型可能要求电缆使用不同的材料或具有不同的性能指标。

2. 温度等级:电缆必须能够在特定的温度范围内正常工作。

温度等级通常以℃表示,例如-40℃至125℃、-55℃至150℃等。

3. 机械强度:在油品存在的环境下,电缆还必须保持足够的机械强度,防止因拉伸、压缩或扭转等外力作用而损坏。

4. 认证标志:电缆产品通常会有相应的认证标志,如CE标志、API(美国石油学会)认证等,这些标志表明电缆符合特定的行业标准和安全要求。

5. 电压等级:耐油电缆的电压等级也是分类的一个重要因素,常见的如0.6/1kV、1.2/2kV、3.6/6kV、6/10kV等。

为了确保电缆产品满足特定应用的要求,制造商会依据相关的欧洲标准(如EN 50265、EN 50395等)生产耐油电缆,并提供相应的技术规格和认证文件。

在选用耐油电缆时,用户需要根据实际应用环境的油品种类、温度条件、机械负荷和电气参数来选择合适的电缆等级。

High temperature cables implies higher current capacity for the same cross-section. The higher the continuous temperature load, the longer the life time of the cable at a given working temperature. Caledonian High Temperature cable allow greater safety margins and higher current capacity, with the following features:•Low weight cable•Low size cable•Thin wall cable•Wide operating temperature range (+125°C down to -60°C)•Low smoke density (>90% light transmission)•Short circuit cable and Earth fault-proof cables (>250°C)Conductors:For 120°C class : Flexible stranded tinned copperFor 150°C class : Flexible plain annealed copperClass 5 (or class 6 on request) according to IEC 60228 with optional separator tapeBraiding:Optional textile braid (for reinforced versions)Insulation: Type EI 111 or EI 112 (if sheathed) cross-linked halogen free silicone rubberSheathing: Low temperature, oil resistant, ozone and UV resistantFor 120°C class : special cross-linked black rubber type EM106 according to EN 50382-1For 150°C class : special cross-linked black silicone rubber type EM 107 according to EN 50382-1Miniumum bending radius:Dynamic use : 5 to 8 x outer diameterStatic use : 4 x outer diameterStandard:EN 50382-1: General requirements applicable to cables, including detailed requirement for the insulating and sheathing materialsHigh temperature rolling stock cables having special fire performanceEN 50382-2 Single core, silicon rubber insulated cables for +120° C and +150° C1.8/3 kV unscreened, unsheathed with or without textile braid 1.5mm2-400mm2FRL-HT-3SU1.8/3 kV unscreened, sheathed with or without textile braid 1.5mm2-400mm2FRL-TW-3S3.6/6 kV unscreened, unsheathed with or without textile braid 2.5mm2-400mm2FRL-TW-6SU3.6/6 kV unscreened, sheathed with or without textile braid 2.5mm2-400mm2FRL-TW-6SCable design in accordance with EN 50264 & EN 50306Cable Make UpConductorsTinned fine copper strands according to VDE 0295 / IEC 60228. class 5 are generally used for railway cables. For nominal cross section of over 50mm sq, 0.41mm strand wire will be used instead of 0.51mm as stipulated in IEC 60228. The IEC 60228 Class 5 enhances flexibility and the ease of handling, thus lengthening the product life of the cable. These class 5 class conductors are extremely flexible, and easy-to-install in the compact rolling stock environment.Insulation and outer sheathCrosslinked polyolefine copolymer or EPR will generally be used for insulation whereas electron-beam cross-linked elastomer is employed for sheathing. Cross-linked elastomer compounds offer very good durability that can resist heat, oil, vibration, chemical aggression, etcElectrical CharacteristicsNominal voltageNominal voltage of a cable refers to the reference voltage for which the cable is intended to be used. In EN 50264. applicable to power cables, different voltage ranges ranging from 0.6/1 kV, 1.8/3 kV to 3.6/6 kV are defined. For each of these voltage ranges, specific insulation thickness requirements are also stipulated in this standard. The operating voltage should not exceed the corresponding maximum nominal voltage allowed.Current Carrying CapacityCurrent carrying capacity is defined as the amperage a conductor can carry before melting either the conductor or the insulation. There are many factors which will limit the amount of current that can be passed through a wire. These major determining factors are: Conductor Size:The larger the circular mil area, the greater the current carrying capacity. The amount of heat generated should never exceed themaximum temperature rating of the insulationAmbient temperature:The higher the ambient temperature, the less heat required to reach the maximum temperature rating of the insulation.Conductor Number:Heat dissipation is lessened as the number of individually insulated conductors, bundled together, is increasedInstallation Conductors:Restricting the heat dissipation by installing the conductors in conduit, duct, trays or raceways lessens the current carrying capacity. This restriction can be alleviated somewhat by using proper ventilation methods, forced air cooling, etc.According to EN 50343. “Railway applications - Rolling stock – Rules for installation of cabling” current carrying capacity are based on maximum conductor temperatures of 90°C and 150°C defined in 3 b. The ambient temperature is 45°C. The following table shows the current carrying capacities for a cable installed in mid air.Current carrying capacity for cables in accordance with EN 50264Nominal cross section of copper conductormm2Current carrying capacityConductor temp. 90 °C (max)Ambient temp. 45 °CI [A]Current carrying capacityConductor temp. 150 °C (max)Ambient temp. 45 °CI [A]0.5 14 -0.75 16 -1 20 -1.5 25 -2.5 33 464 46 646 60 8410 85 11916 110 15425 150 21135 190 26750 240 33770 300 42295 360 506120 425 598 150 490 689 185 560 788 240 675 950 300 775 1091 400 950 1337 Ambient temperatureExternal conditions such as ambient temperature and bundling must be taken into account whendetermining actual current carrying capacity.

This meansthat for a period of less than or equal to 50 hours, increased conductor temperatures can be withstood, while the operability of the cablesremains unimpaired. This has the advantage that short-time temperature increases can be identified and more serious damage such asfires can be prevented.Environmental conditionsCables are suitable for fixed installation in rail vehicles up to – 40°C and are resistant to oil according to EN 50305. EN 60811-2-1. UIC895 and resistant to fuel according toEN 50305. EN 60811-2-1. UIC 895.Fire PerformanceEN 50264 and EN 50306 only describe cables and wires made from halogen free materials that minimise the risk of damage to personsand property. These materials refer to hazard levels 1 – 4 as defined in EN 45545-1( fire protection on railway vehicles). These levelsdefine the degree of possibility of personal injury as the result of a fire. Amongst other things, they also form the basis of the requirements for materials used in rail vehicles.Halogen FreeThe test is for determination of the amount of halogen acid gas, other than the hydrofluoric acid evolved during combustion of compound. When tested in accordance with IEC 60754-1. the hydrochloric acid yield should be less than 0.5% (5mg/g) for LSOH compound. CorrosivityCorrosive gases produced in case of fire cause damage to vehicles and facilities and therefore should be avoided. According to EN50267-2-2. a material is not corrosive if its combustion gases meet the stipulated target values for conductivity (≤ 10 s/mm) and pH value (≥ 4.3).This is equivalent to IEC 61034ToxicityIn accordance with EN 50305- 9.2. or NFC-20454 a toxicity index (ITC) is calculated following analysis and titration of combustion gases. The aforementioned hazard levels require that certain toxicity indices are not exceeded.The toxicity indices for power cables listed in the following table are derived from EN 50264.HL ITCHL 1 not specifiedHL 2 / HL 3 5 (max)HL 4 3 (max)The required toxicity indices for cables and wires, depending on hazard level, in accordance with EN 50306 (thin wall) are displayed in the following table:HL ITCInsulation and sheath S1EM101-104 and sheath S2 HL 1 not stipulated not stipulated HL 2 / HL 3 10 (max) 5 (max)HL 4 6 (max) 3 (max)Toxic FumesNaval standard NES713 burns a set amount of material and analyses the gases given off. The volume of each gas is multiplied by the toxicity index for each gas. The toxicity index for each gas are added together to give an overall toxicity index for the material. LFH materials should have a toxicity index maximum of 10.Flame RetardanceIn accordance with EN 50265- 2-1 or IEC 60332-1. testing is carried out for a single insulated wire or cable. The specimen is deemed to have passed this test, if after burning has ceased, the charred or affected position does not reach within 50mm of the lower edge of the top clamp.In accordance EN 50266-2-4. EN 50305 9.1 and IEC 60332-3. testing is carried out for bunched cables. A gas burner flame is applied to the bottom of a vertically arranged conductor bundle in a test furnace. Following completion of the flame test, the specimen consisting of 3.5m, is deemed to have met the requirements, if after burning has ceased, the extent of charred of affected portion does not reach a height exceeding 2.5m above the bottom edge of the burnerSmoke DensityFor smoke density testing, the cube test is employed according to EN 50268-2-1 or IEC 61034. The 3 metre cube test measures the generation of smoke from electric cables during fire. A light beam emitted from a window is projected across the enclosure of to a photo cell connected to a recorder at the opposite window.The recorder is adjusted to register from 0% for complete obscuration to 100% luminous transmission. A 1 metre cable sample is placed in the centre of the enclosure and then subjected to fire. The minimum light transmission of the smoke is then measured.The following table shows the minimum percentages of light transmission depending on hazard level:HL Light transmissionHL 1 not specifiedHL 2 / HL 3 60 %HL 4 70 %BS 6853.In 1999. BS 6853 was introduced in UK and whose highest categories are probably the most demanding in the world. BS 6853 covers both smoke emission testing and flammability testing. BS 6853 also introduced the concept of an R-Index, which is a single number quantification of the toxic gas risk associated with candidate composite materials for use in railway rolling stock. The R-Indices are split into the following categories:Category 1a Trains which predominantly use tunnels R < 1.0Category 1b Trains which use tunnels, but infrequently R < 1.6Category 2 Trains which run, predominantly, overground R < 3.6The R-Index is generated by analysing eight gases of combustion, for which critical concentrations have been established byNIOSH/OSHA and reported as IDLH, (Immediately Dangerous to Life and Health), values.Toxicity is the most important factor to address during the cable design. Toxicity limit for the UK and France are identical because both require the same test method for elastomers (NF X 70-100). The only difference is that the U.K.'s specification requires an addendum for nitrous oxides. Toxicity limits for French and the U.K. standards are developed from the IDLH values published in the National Institute for Occupational Safety and Health (NIOSH) Guide. IDLH, or Immediately Dangerous to Life or Health, values are calculated based on levels of gas in a particular atmosphere for 30 min that would pose an immediate riskthe U.K.'s BS 6853 specification is the most stringent, closely followed by the French, and finally the U.S. It's important to note that Germany does not have a toxicity requirement.

IgnitionThe ignition characteristics is determined by a combination of glow wire test (GWT) and oxygen index.The material under test is categorized in the following tables:Class Oxygen Index Glow WireI0 >70 No ignition at 960CI1 >45 No ignition at 960CI2 >32 No ignition at 850CI3 >28 Ignition does not persist at 850C after glow wire is withdrawnI4 >20NC <70(Not classified)2. Fume compositionThe parameters tested are fume opacity and analysis of pyrolysis as well as combustion gases.All 3 parameters are used to calculate the smoke index ( SI) which in turns determines the fume classF as follows:F Class S.I ValuesF0 ≤ 5F1 ≤20F2 ≤40F3 ≤80F4 ≤120F5 >120ClassificationEach material will receive I/F rating, the smaller the number the better. Unfortunately, good I and good F are difficult to achieve: low I values frequently means addition of fire retardant packages which in turns leads to high F values.Consequently, 4 overall I/F performance classes are defined as follows:I0 I1 I2 I3 I4 I5F0 IV IV IV II I IF1 IV IV IV II I IF2 IV IV III II I IF3 IV III III I I IF4 IV III I I I IF5 IV I I I I II Performance class 1. least demandingII Performance class 2III Performance class 3IV Performance class 4. most demandingDIN 5510In Germany, the fire standards requirements in railways are defined by the DIN 5510. which does not include any measurement of toxic gases but focuses only on reaction to fire and smoke produced in a fire scenario.According to DIN5510. the test samples, vertically arranged in the test chimney, are stressed by a special bunsen burner for 3 minutes. The combustibility, smoke release and dripping behaviour are then assessed.The extent of destroyed surface area is decisive of the fire performance rating. The following are the fire performance classification: ClassB1 Easily ignitable Damaged area 90%-100%B2 Combustible Damaged area 76%-90%B3 Difficult to ignite Damaged area <75%B4 Incombustible No damageThe rating with respect to burning dripping are also observed in the chimney test. Differentiation between the classes is based on visual observation by T1 burning dripping to T4 no visible deformation/ no softening.The smoke release during the chimney test will be done by the reduced transmission value. Two classes, SR1 10% min and SR2 < 50% min are used.EN 45545En 45545 is a common new EU standard is to replace the existing national regulations for fire safety in trains and track-guided vehicles. This new standard constitutes a harmonising of the existing national standards based on the highest common denominator – and will therefore represent a stiffening of the fire safety regulations applied in the individual countries.The new standard divides railway vehicles into four operation categories. As seen below, it particularly targets safety in connection with tunnels and bridges:Category Services Infrastructure1 Mainline, regional, urban andsuburban Operation not determined by underground sections, tunnels and/or elevated structures2 Urban and suburban Operation determined by underground sections, tunnels and/orelevated structures with walkways or other means for safe sideevacuation from the vehicles3 Mainline and regional Operation determined by underground sections, tunnels and/orelevated structures with walkways or other means for safe sideevacuation from the vehicles4 Mainline, regional, urban andsuburban Mainline, regional, urban and suburban operation determined by underground sections, tunnels and/or elevated structures without any means for safe side evacuation from the vehiclesThe standard also establishes four hazard levels that determine the requirements for protection against fire and smoke formation. Most new railway vehicles will be designed to hazard level 3. but some vehicles, for example for light rail systems, will have to conform to hazard level 4.:category Category DesignStandard vehicles Automatic vehicles Double-decked vehicles Sleeping cars1 HL2 HL 2 HL 2 HL 22 HL 2 HL3 HL 3 N/A3 HL 3 HL4 HL 3 HL 44 HL 4 HL 4 HL 4 HL 4HL 1 Long distance trainHL2 Regional train without tunnelHL3 High speed trainsCity and regional trainsTrams with party going through tunnels.HL4 MetroNight train with sleeping coachesOrdering CodeFRL-A-BC-D-E-F-GA- Wall TypeSW- Standard WallMW- Medium WallTW- Thin WallHT- High TemperatureB- Voltage Type05-300/500V06-0.6/1KV3-1.8/3KV6-3.6/6KVC- Core TypeS- Single CoreM-Multi CoreMP-Multi PairD-Insulation or Sheath TypeU-UnsheathedSW-Standard Wall SheathESW-Exposed Standard Wall SheathRI-Reinforced InsulationE- Screen TypeOS-Overall ScreenIOS-Individual & Overall ScreenF-Number of Cores and Pairs10C- 10 CoresG- Cross Section Areas1.5- 1.5mm2Test MethodEN 50305Test MethodsSpecial test are stipulated in EN 50305 for each European railway rolling stock.
