  • 如何判断铝合金电缆厂家好不好?
  • 本站编辑:杭州逸捷暖通设备有限公司发布日期:2019-10-27 16:53 浏览次数:

当前铝合金电缆已经逐步被市场认可,越来越多的用户计划选用铝合金电缆。


然而


标准和监管滞后,


市场上鱼目混珠、良莠难辨,


不具备生产技术和设备的企业大肆推销,


给用户的选择带来了极大的困惑。


今天我们就来说说

以下,杭州逸捷暖通设备有限公司为大家具体总结了铝合金电缆的生产技术、装备、工艺成熟度、行业标准、试验报告等10个标准,对铝合金电缆厂家进行鉴别。


具备前5条的,可以判定是一家合格的铝合金电缆生产厂家,如果10条标准全部都具备,那就是一家出色的铝合金电缆生产厂家。


通过以上10条标准,对于如何选择一家出色的铝合金电缆生产厂家,就能够做出准确的判断。


绝大部分不具备铝合金电缆生产技术和设备的、能力差的、不专业的厂家基本可以排除在外了。


这样选择的企业和产品品质应该是比较安全可靠了!


1、产品品质



铝合金电缆主要是由导体、绝缘和铠装(护套)组成的,从铝合金电缆基本三要素着手进行分析,对于铝合金电缆的品质就能够看出个大概。


(一)铝合金导体杆材:看是否能够独立自主生产出高品质的铝合金导体杆材


目前国内拥有自主铝合金导体生产技术的厂家不多,具备能够连续熔炼、连续浇铸、连铸连轧的铝合金导体杆材生产线更是屈指可数,若不具备自主的铝合金导体杆材生产能力,依靠委托加工、所谓秘密熔炼、或者其他无正规来路购买来的铝合金导体杆材,不仅无法保证铝合金电缆的基本品质,也无法从源头上对电缆的品质进行把控。


除具备熔炼、连续浇铸、连铸连轧的铝合金导体杆材生产线外,还要看其生产线连续浇铸的铸坯截面的大小,越大截面,轧制出的铝合金杆材品质越优异,"千锤百炼出好钢"。优异的铝合金导体杆材是铝合金电缆电气性能、机械性能的决定性因素,若不具备高质量的铝合金杆材,后道工序无论怎样拉丝、绞丝、成缆、铠装等都无法改变其导体的基本品质。


(二)绝缘:关于绝缘有三看;交联度、绞合导体、导体成缆退火


(1)交联度;铝合金电缆优于铜缆的其中一点是铝合金电缆全部采用交联聚乙烯绝缘,电缆工作温度为90度。正因为采用交联聚乙烯绝缘,就存在交联度问题,正规的专业铝合金电缆生产厂家应有专门的交联室。


(2)绞合导体:看导体的绞合技术和导体绞合生产线,目前国内线缆行业绞合导体设备基本类同,生产的绞合导体,通常会产生铝屑和毛刺,损伤绝缘,影响绝缘效果,造成安全隐患和缩短绝缘寿命。最先进的绞合导体设备是分电机式的、PLC程序控制的纳米技术导体绞合装备,采用这种先进的工艺装备、微机控制生产编程、创新的顶级纳米技术,生产的铝合金导体表面无铝屑、无毛刺、无油污、无凹凸、无刮伤、无划痕,能最有效地保证电缆绝缘无任何损伤和破坏,确保产品使用寿命大大高于同类产品。


(3)导体成缆退火:通常导体绞合后绞合导体存在的内应力会施加在绝缘上,使绝缘长期受力,加速绝缘老化,影响绝缘使用寿命,从而直接影响电缆的使用寿命,这就是铜缆使用寿命不长的原因。美国的铝合金生产工厂都采用导体成缆退火工艺解决内应力问题。成缆退火工艺技术,可以进一步提高产品的电气和机械性能,同时消除了导体绞合过程产生的内应力,有效地保障了绝缘的使用寿命。所以必须看是否有成缆退火工艺技术和具有导体成缆退火炉装备。


(三)铠装:看是否有先进的铝合金联锁铠装设备


国内很多生产厂家的铝合金铠装由于装备水平差,工艺水平不达标,以至合金带较宽,铠装波峰间距较大,造成电缆僵硬,弯曲不灵活,容易脱铠,抗压性能差,效果欠佳。目前最先进的铝合金联锁铠装设备是加拿大的卡尔马克(KALMARK)铝合金联锁铠装生产线,该设备生产的联锁铠装紧密性好,铠铠之间环环相扣,不易脱开。


由于铠装波峰之间的间距小,相同距离的铠装相对于其他铠装产品受力点多,能够承受更大的压力而不会对电缆缆芯造成损伤。由于波峰多,弯曲半径更小,耐弯曲性能更好。这种铝合金铠装才能真正达到美国标准对铝合金铠装的要求。


2、制造装备



主要考察企业是否有先进的铝合金电缆生产制造装备和技术工艺装备。


(1)铝合金导体杆材连铸连轧生产线


铝合金电缆的关键是铝合金导体的生产,所以,选择厂家的时候首先要看一看,有没有先进的铝合金导体杆材连铸连轧生产线。


目前国内最先进的铝合金导体杆材生产设备是意大利技术、能连续浇铸大截面(3807mm2,其它意大利进口的生产线最大浇铸截面只能达到2400mm2)的连铸连轧生产线,3807mm2的铝合金铸坯经过千锤百炼、大压缩比连续粗轧制、多道次连续精压延可以获得杆材强度适中、体积密度大、导电性能最佳、各项技术指标最优异的铝合金杆材,这种铝合金杆材拉出的合金丝用到铝合金电缆导体的导电线芯是电缆叠加组合的最佳产品。


如果一个工厂自己没有先进的铝合金导体杆材连铸连轧生产线,铝合金导体质量无法从生产源头开始控制,则铝合金电缆质量就更无法保障!


(2)导体绞合生产线


目前国内一般厂家导体绞合生产线生产的绞合导体,通常会产生铝屑和毛刺,损伤绝缘,严重影响绝缘效果,造成安全隐患和缩短绝缘寿命。目前国内最先进的导体绞合生产线是分电机式的、PLC程序控制的纳米级绞线机生产线,采用纳米技术生产的铝合金导体表面无铝屑、无毛刺、无油污、无凹凸、无刮伤、无划痕,能最有效地保证电缆绝缘无任何损伤和破坏,确保产品使用寿命大大高于同类产品。


(3)铝合金联锁铠装生产线


目前世界最先进的铝合金联锁铠装机生产线是加拿大的卡尔马克(KALMARK)铝合金联锁铠装机生产线,该生产线依据美国技术标准开发研制的铝合金带连锁铠装电缆,其层与层之间联锁的特殊结构能够保证电缆经受外界强大的外力破坏,即使电缆遭受较大的外界压力和外界冲击力,铠装层也能保护绝缘层电气性能。


铝合金非磁性铠装层的结构也有效地提高了电缆的阻燃级别,大大降低了火灾或火情对电缆的危害,非磁性的铝合金铠装也极大的降低了电缆涡流损耗。铝合金带铠装结构相对钢带铠装其重量轻、无涡流损耗、敷设便利、易于弯曲、勿需桥架安装,能减少20%-30%的安装敷设成本并提高了安装效率。


3、检测报告



主要考察企业产品是否经过国家权威机构有关产品特性、耐火、阻燃、烟气毒性、透光率等各类试验和检测认证。


(1)三个必须的技术报告:即《铝合金导体材料检验报告》、《铝合金导体抗压蠕变性能试验报告》和《过渡端子1000次热循环试验报告》。第一个是铝合金导体材料是否符合AA8000牌号要求的化学成分要求的报告,第二个是铝合金直接区别纯铝的报告,第三个是连接端子的可靠性报告,这三个技术报告是合格的铝合金电缆必须具备的。


(2)中国国家电线电缆检测中心、国网武汉高压研究所等国家级检测机构出具的铝合金电缆产品的检验报告。


(3)国家防火建筑材料质量监督检验中心等出具的产品耐火、阻燃、烟气毒性、透光率等的检测报告。


(4)在选用无卤低烟产品时要特别注意看国家防火建筑材料质量监督检验中心出具的烟毒、透光率的检测报告;目前国内很多厂家号称生产的铝合金电缆无卤低烟,而实际产品采用的材料达不到无卤低烟的要求,这从检测报告中可以看出。


国家标准(GB/T20285-2006材料产烟毒性危险分级)中有关烟毒检测安全级别中规定;烟毒安全性:AQ1>AQ2>ZA1>ZA2>ZA3>WX;透光率要大于60%,其中(AQ:为安全级,ZA为准安全级,WX为危险级)。


铝合金产品检测结果,只有烟毒指标达到AQ级别且透光率大于60%的才是真正无卤低烟产品,才是真正安全可靠的,即使电缆被燃烧也不会释放出有毒气体,敷设、安装、使用安全性高。


(5)至于其它所谓的评估报告、行业证明等,实际上都是一些企业在玩虚的。大家都知道,这些东西,都是些行业部门办的咨询、中介机构出具的,只要缴纳费用,就不难搞到。这些报告、证明等,对产品品质来说,不能说明或证明什么,不足以作为参考。


4、自主知识产权、技术专利


铝合金电缆在国内属新型导体材料产品,现时使用的标准没有对铝合金导体材料专门的规定条款,为避免材料技术来源不明,导致铝合金电缆产品性能、质量不能保证,选择的制造厂家必须拥有该导体材料及制造技术的自主知识产权专利证书。


是否拥有核心的铝合金导体熔炼配方及制备的专利技术和自主知识产权,这是体现一家企业拥有雄厚技术实力的基础条件。众所周知,若不具备铝合金导体的核心技术,再响亮的广告宣传也很难保证是正宗的铝合金电缆。


拥有发明专利的核心技术铝合金配方是铝合金导体生产第一道工序中熔炼、铸坯、轧制杆材的首要前提,没有真正的铝合金发明专利配方,再先进的连铸连轧工艺装备也无济于事。铝合金材料专利配方是实施高水平铝合金电缆加工制造、工艺技术的前提条件,是铝合金电缆品质优异的保证,是一家企业真正的技术优势。


5、质量控制


电缆是能源传输的动脉,关系着一个企业乃至一个地区电力传输的安全平稳运行,铝合金电缆的质量至关重要,不能够有半点马虎。生产铝合金电缆产品与生产铜电缆在生产工艺上有很大的不同,生产铝合金电缆,需要很多专业的检测设备和完善的质量管理体系。


每一批次的铝合金电缆都是需要经过生产各环节进行严密的检测、检验、才能够出厂的。考察一个厂家对待品质控制的态度,从投入的人员、资金、机构就可以看出来,一家专业的铝合金电缆厂家应设有专门的品质管理办公室、化学分析实验室、机械性能实验室、物理性能实验室、光谱分析实验室、电气性能实验室等,优秀的企业质量控制是从冶炼合金铝液到连铸连轧;从铝合金杆拉丝、紧压绞合到导体热处理;从导体绝缘挤出、交联到绝缘线芯成缆;最后到铠装、护套、例行试验、包装出厂的每一个过程都有完善、严格的跟踪检验,即从源头开始控制,确保生产出的成品电缆拥有最高品质。


对生产的产品进行全程质量控制,时间节点精确到每分每秒,并在铝合金电缆结构中进行相应标注,确保每一寸铝合金线缆的品质控制的可追溯性。


在众多的检测设备中重要的检测设备之一是铝合金导体材料检测设备,目前国际上最先进的铝合金导体材料检测设备是德国的全谱直读等离子发射光谱仪,其检测速度最快,精度最高。光谱仪主要是用来检测铝合金材料的化学成分和合金的结晶状态。没有先进的检测设备是无法保证铝合金导体质量的!


6、技术标准


铝合金电缆的国家行业标准已经报国家主管部门审批,如果是参与国家标准制定的,同时又是专业生产铝合金电缆的公司,那一定是在行业内有实力、有影响力的领先企业,美国是铝合金电缆的发明地,美国的铝合金电缆制造技术和安装经验要领先国内40年以上,因此,客观来说,美国的公司,尤其是最早从美国带进铝合金电缆技术并采用美国标准制造的铝合金电缆生产厂家,安全性和可靠性就更有保障。


7、客户案例


铝合金电缆应用范围覆盖住宅、商业、工业建筑等领域,客户的反馈是很具有参考价值的,应该重点了解一下客户使用铝合金电缆的运行情况、售后维护情况,如果客户的电缆三天两头出现问题要厂家进行售后维护,说明电缆质量有待考究。


一个快速判断铝合金电缆厂家的方法就是考察电力设计单位,如果一家电力工程咨询和设计的单位其本身的大楼项目电力传输都是采用铝合金电缆,那么该供货厂家和产品一定是经过充分而严密的科学论证过的,可以放心选择。


8、增值服务


国内一般的企业都是用做铜缆的思维来做铝合金电缆,铝合金电缆只是其产品系列中的一个品种,经营铝合金电缆的思路也是延用铜缆的思路,单纯卖电缆。


如今,用单纯卖电缆的思维来卖铝合金电缆已经不符合时代和社会发展的要求,生产铝合金电缆是有很高的技术门槛的,一家有实力的铝合金电缆生产厂家,不仅要能够提供最优质的铝合金电缆产品,还应该能够提供整套的电缆传输解决方案,电缆连接端子解决方案,并帮助客户做《项目技术解决方案》,《产品全寿命周期成本分析报告》等技术、商务方案,帮助客户提供电缆选型、安装指导、人员培训、运行监测等附加增值服务,没有专业的实力,没有对铝合金电缆这个行业的重视和准备长期服务铝合金电缆用户的态度的企业是很难做到的。


9、实地考察


由于国内电缆产品都是实行送检制度,行业内通行的给客户看的样品也无一例外都是委托礼品公司制作的,检测机构出具的报告只是对送检样品负责。如果实际供货的产品出现了问题,损害的是用户的利益。一些不良的厂商就是钻政策的空子,把其他厂家的样品换了标牌之后拿去相关检测机构检测,用正规工厂的产品当做自己的产品去做给客户看的样品,欺瞒检测机构和用户,也说自己有检验报告,样品也很漂亮,而实际供货的产品与样品相差甚远,甚至不能保证产品的质量。Aluminum alloy cable has been gradually recognized by the market, more and more users plan to choose aluminum alloy cable.




However,




Standards and regulations lag,




In the market it is difficult to distinguish the good from the bad,




Companies that don't have the technology or equipment to make it,




The choice to the user brought great confusion.




Let's talk about it today


The following, hangzhou yijie hvac equipment co., LTD. For everyone specific summary of aluminum alloy cable production technology, equipment, process maturity, industry standards, test report and other 10 standards, aluminum alloy cable manufacturers to identify.




With the first 5, can be judged to be a qualified aluminum alloy cable manufacturers, if all 10 standards have, it is an excellent aluminum alloy cable manufacturers.




Through the above 10 standards, for how to choose an excellent aluminum alloy cable manufacturers, can make accurate judgment.




Most do not have aluminium alloy cable production technology and equipment, poor capacity, not professional manufacturers can be excluded.




Such choice of enterprise and product quality should be more safe and reliable!




1. Product quality






Aluminum alloy cable is mainly composed of conductor, insulation and armor (sheath).




(a) aluminum alloy conductor rod: see if you can independently produce high-quality aluminum alloy conductor rod




The manufacturer of current domestic production technology with independent aluminum alloy conductor is not much, have a continuous smelting, continuous casting, continuous casting and rolling of aluminum alloy conductor rod production line is a handful, if do not have independent of aluminum alloy conductor rod production capacity, to rely on processing, the so-called secret melting, or other no formal approach for aluminium alloy conductor rod, not only cannot assure the basic quality of aluminum alloy cable, nor from the source to control the quality of the cable.




In addition to the smelting, continuous casting, continuous casting and rolling of aluminum alloy conductor rod production line, but also to see the size of the continuous casting of the billet section of the production line, the larger the section, the rolled aluminum alloy rod quality is better, "good steel". Excellent aluminum alloy conductor rod is the decisive factor of the electrical and mechanical properties of aluminum alloy cable. Without high quality aluminum alloy rod, the basic quality of conductor cannot be changed no matter how to draw, twist, cable and armor in the latter process.




(2) insulation: there are three aspects about insulation; Cross - linking degree, stranded conductor, conductor cable annealing




(1) crosslinking degree; One of the advantages of aluminum alloy cable over copper cable is that all aluminum alloy cables are insulated by crosslinked polyethylene and the operating temperature of the cable is 90 degrees. Because of the use of crosslinked polyethylene insulation, there is a problem of crosslinking degree, formal professional aluminum alloy cable manufacturers should have a special crosslinking room.




(2) stranded conductor: according to the stranded conductor technology and the stranded conductor production line, the stranded conductor equipment in the domestic cable industry is basically the same. The stranded conductor usually produces aluminum chips and burrs, damages the insulation, affects the insulation effect, causes safety risks and shortenes the insulation life. Points is the most advanced stranded conductor device of motor type, PLC program control of nanotechnology stranded conductors and equipment, adopting the advanced process equipment, microcomputer control programming, innovation of the top nanotechnology, production of aluminum alloy conductor surface without aluminum, no burr, no pollution, no bumps, no scratch, no scratches, can most effectively to ensure no damage and cable insulation damage, ensure that the product service life and much higher than similar products.




(3) conductor cable forming annealing: generally, after conductor stranding, the internal stress existing in the stranding conductor will be applied on the insulation, causing long-term stress on the insulation, accelerating insulation aging, affecting the service life of the insulation, thus directly affecting the service life of the cable, which is the reason why the service life of copper cable is not long. Aluminum alloy production plants in the United States adopt the conductor forming annealing process to solve the problem of internal stress. The cable annealing technology can further improve the electrical and mechanical properties of the products, and eliminate the internal stress generated in the conductor stranding process, effectively ensuring the service life of the insulation. Therefore, it is necessary to see whether there is cable annealing technology and cable annealing equipment with conductor.




(3) armor: see if there is an advanced aluminum alloy interlocking armor equipment




The aluminum alloy armor made by many domestic manufacturers is not up to standard due to the poor equipment level and the substandard technology, so that the alloy belt is wider and the peak spacing of the armor is larger, which causes the cable to be rigid, inflexible in bending, easy to take off the armor, poor compression resistance and poor effect. At present, the most advanced aluminum alloy interlock armor equipment is Canada's KALMARK aluminum alloy interlock armor production line. The interlock armor produced by this equipment is of good tightness, interlocking and not easy to detach.




Due to the small spacing between the armor crest, the armor with the same distance has more stress points than other armor products, which can withstand greater pressure without causing damage to the cable core. Due to more peaks, smaller bending radius, better bending resistance. This kind of aluminum alloy armor can really meet the requirements of American standard for aluminum alloy armor.




2. Manufacturing equipment






Whether the enterprise has advanced aluminum alloy cable manufacturing equipment and technology equipment.




(1) continuous casting and rolling production line of aluminum alloy conductor rod




The key of aluminium alloy cable is the production of aluminium alloy conductor, so, when choosing manufacturer, want to look above all, have advanced aluminium alloy conductor rod material continuous casting continuous rolling production line.




The current domestic most advanced aluminum alloy conductor rod material production equipment is the Italian technology, continuous casting large cross-section other Italian imports of production lines (3807 was the biggest casting section of 2400 was only) of the continuous casting and rolling production line, 3807 aluminum alloy slab was filleting, large compression ratio for rough rolling, multi-channel time continuous rolling can get rod with moderate intensity, large volume density, conductivity best, various technical indicators are the most excellent aluminum alloy rod, the aluminium alloy rod material pull wire used aluminum alloy cable conductor of conductive wire core is the best product for cable superposition combination.




If a factory does not have the advanced continuous casting and rolling production line of aluminum alloy conductor rod, the quality of aluminum alloy conductor cannot be controlled from the production source, and the quality of aluminum alloy cable cannot be guaranteed!




(2) conductor stranded production line




At present, the stranded conductor produced by the stranded conductor production line of general domestic manufacturers will usually produce aluminum chips and burrs, which will damage the insulation, seriously affect the insulation effect, cause safety hazards and shorten the insulation life. At present domestic most advanced stranded conductors is the production line by motor, PLC program control of nanoscale stranding machine production line, using nanometer technology in the production of aluminum alloy conductor surface without aluminum, no burr, no pollution, no bumps, no scratch, no scratches, can most effectively guarantee cable insulation without any damage and destruction, ensure the service life of the product compared with similar products.




(3) aluminum alloy interlocking armor production line




Is one of the world's most advanced aluminum alloy interlocking armoring machine production line is the Canadian Karl mark (KALMARK) aluminum alloy interlocking armoring machine production line, the line is designed according to the technical standards development of aluminum alloy with armored cable chains, the interlocking between layer and layer of special structure can ensure cables subjected to the outside world strong external force damage, even though cable bigger pressure and external impact, armoured layer can also protect the electrical insulation properties.




The structure of aluminum alloy non-magnetic armor layer also effectively improves the flame retardant level of the cable, greatly reduces the damage of fire or fire to the cable, and greatly reduces the eddy current loss of the cable. Compared with steel tape armored structure, aluminum alloy tape armored structure has light weight, no eddy current loss, convenient laying, easy bending and no need of bridge installation, which can reduce 20% to 30% of installation cost and improve installation efficiency.




3. Test report






Whether the products of the enterprise have passed all kinds of tests and tests and certifications related to product characteristics, fire resistance, flame retardant, smoke toxicity, light transmittance and so on.




(1) three necessary technical reports: inspection report on aluminum alloy conductor materials, test report on compressive creep performance of aluminum alloy conductor and test report on 1000 thermal cycles of transition terminal. The first is the aluminum alloy conductor material whether to meet the AA8000 brand requirements of the chemical composition requirements of the report, the second is the aluminum alloy directly distinguish pure aluminum report, the third is the connection terminal reliability report, these three technical reports are qualified aluminum alloy cable must have.




(2) inspection report of aluminum alloy cable products issued by China national wire and cable testing center, state grid wuhan high voltage research institute and other national testing institutions.




(3) the inspection report on product fire resistance, flame retardant, smoke toxicity and light transmittance issued by the national fire prevention building materials quality supervision and inspection center.




(4) when choosing halogen-free and low-smoke products, special attention should be paid to the smoke toxicity and light transmittance test report issued by the national fire prevention building materials quality supervision and inspection center; At present, many domestic manufacturers so-called production of aluminum alloy cable halogen-free low smoke, and the actual product materials can not meet the requirements of halogen-free low smoke, this can be seen from the test report.




In the national standard (GB/ t20285-2006 material smoke toxicity risk classification) in the smoke toxicity testing safety level provisions; Smoke safety: AQ1>AQ2>ZA1>ZA2>ZA3>WX; Light transmittance should be greater than 60% where AQ: safe, ZA: safe and WX: dangerous.




Aluminum alloy products test results, only smoke toxicity index reached AQ level and light transmittance more than 60% is truly halogen free low smoke products, is truly safe and reliable, even if the cable is burned will not release toxic gas, laying, installation, use safety is high.




(5) as for other so-called evaluation reports, industry certificates, etc., in fact, some enterprises are playing virtual. Everybody knows, these things, it is the consultation that some industry branch does, intermediary orgnaization issues, want pay fee only, it is not difficult to get. These reports, certificates, etc., do not prove or prove anything about the quality of the product and are not enough for reference.




4. Independent intellectual property rights and technical patents




Aluminum alloy cable in the domestic new conductor material products, the current use of standard without special terms of aluminum alloy conductor material, in order to avoid material source technology, lead to aluminum alloy cable product performance, quality can't guarantee anything, choose the manufacturer must have the conductor material and manufacture technology of independent intellectual property rights patent certificate.




Whether has the core aluminum alloy conductor melting formula and the preparation of the patent technology and independent intellectual property rights, which reflects an enterprise has strong technical strength of the basic conditions. As we all know, without the core technology of aluminum conductor, it is difficult to guarantee that it is authentic aluminum cable no matter how loud the advertisement.




Having the core technology of invention patent aluminum alloy formula is the first premise of melting, casting billet and rolling rod in the first process of aluminum alloy conductor production. The patented formula of aluminum alloy material is the precondition for the high level aluminum alloy cable processing and manufacturing, the guarantee of the excellent quality of aluminum alloy cable, and the real technological advantage of an enterprise.




5. Quality control




Cable is the artery of energy transmission, which is related to the safe and stable operation of power transmission in an enterprise or even a region. Production of aluminum alloy cable products and production of copper cable in the production process is very different, the production of aluminum alloy cable, need a lot of professional testing equipment and improve the quality management system.




Each batch of aluminum alloy cable is the need to go through the production of each link for strict detection, inspection, can be factory. Visit a manufacturer attitude toward quality control, from the input of personnel, capital, institutions can see out, a professional manufacturer of aluminum alloy cable should be equipped with a special quality management office, laboratory chemical analysis laboratory, mechanical properties, physical properties of the laboratory, spectral analysis laboratory, electric laboratory performance and so on, excellent enterprise quality control, alloy aluminum liquid from smelting to continuous casting and rolling; From aluminum alloy rod wire drawing, tight stranding to conductor heat treatment; From the conductor insulation extrusion, crosslinking to the insulation core into a cable; Finally, every process of armor, sheath, routine test and package delivery has perfect and strict follow-up inspection, that is, control from the source to ensure that the finished cable produced has the highest quality.




The whole process quality control of the products is carried out, the time node is accurate to every minute and second, and the corresponding notes are made in the aluminum alloy cable structure to ensure the traceability of quality control of every inch of aluminum alloy cable.




One of the most important detection equipment is aluminum alloy conductor material detection equipment. Currently, the most advanced detection equipment for aluminum alloy conductor material in the world is Germany's full-spectrum direct-reading plasma emission spectrometer, which has the fastest detection speed and highest accuracy. The spectrometer is mainly used to detect the chemical composition of aluminum alloy and the crystal state of alloy. No advanced detection equipment is not able to ensure the quality of aluminum conductor!




6. Technical standards




Aluminum alloy cable has been reported to the competent national department for examination and approval of the national industry standard, if it is to participate in national standards, is specializing in the production of aluminum alloy cable companies at the same time, it must be inside the industry strength, influential leading enterprises, the United States is the invention to aluminum alloy cable, installation of aluminum alloy cable manufacturing technology and experience to lead the domestic more than 40 years, therefore, objectively speaking, the companies in the United States, especially the first brought into the aluminum alloy cable technology from the United States and USES the standard American manufacturing aluminum alloy cable manufacturers, security and reliability is more secure.




7. Customer cases




Aluminum alloy cable application range covers areas such as residential, commercial, industrial buildings, customer feedback is very has the reference value, should focus on understanding the customers to use aluminum alloy cable operation situation and situation of after-sales maintenance, if the customer's cable problems three days two head to manufacturer for after-sale maintenance, cable quality needs to be fastidious.




A quick way to judge aluminum cable manufacturers is to investigate the power design unit, if a power engineering consulting and design unit of its own building project power transmission are using aluminum cable, then the supplier and product must be through full and rigorous scientific demonstration, you can rest assured that the choice.




8. Value-added services




Domestic general enterprises are used for copper cable thinking to do aluminum cable, aluminum cable is only a variety of its product series, aluminum cable management is also the idea of copper cable, pure selling cable.




Now, with pure sell cable thinking to sell aluminum alloy cable has not meet the requirements of The Times and social development of production of aluminum alloy cable is a high technical threshold, a powerful aluminum alloy cable manufacturer, should not only be able to provide the best quality aluminum alloy cable products, should also be able to provide a complete set of cable transmission solutions, cable connection terminal solutions, and help customers to do the project technical solutions, the products whole life cycle cost analysis report, such as technology, business plan, help customer to provide cable selection, installation guide, additional value-added services, such as personnel training, running monitoring without professional strength, Without the importance of aluminum cable industry and prepared for the long-term service of aluminum cable users of the attitude of the enterprise is very difficult to do.




9. Field trip




Because domestic cable products are the implementation of the inspection system, the industry is common to the customer to see the samples without exception are commissioned by the gift company, the inspection agency issued the report is only negative to the sample sent for inspection
