阻燃的低壓無鹵電線電(dian)(dian)(dian)纜(lan)(lan)老(lao)化(hua)原因：外力的(de)損(sun)(sun)傷。由近幾年的(de)數據分(fen)析來看，尤其是在經(jing)(jing)濟高(gao)速(su)發(fa)(fa)展中(zhong)的(de)上海(hai)，現在的(de)大多數電(dian)(dian)(dian)纜(lan)(lan)故(gu)障都是因為機(ji)(ji)械損(sun)(sun)傷引(yin)起(qi)的(de)。譬(pi)如：電(dian)(dian)(dian)纜(lan)(lan)在敷設安(an)裝的(de)過(guo)程中(zhong)不按照正常規范施(shi)工，容易(yi)造(zao)成(cheng)(cheng)機(ji)(ji)械損(sun)(sun)傷；在直埋電(dian)(dian)(dian)纜(lan)(lan)上建(jian)造(zao)施(shi)工也特別容易(yi)將運行(xing)中(zhong)的(de)電(dian)(dian)(dian)纜(lan)(lan)損(sun)(sun)傷等。有時如果(guo)損(sun)(sun)傷不嚴重(zhong)，要經(jing)(jing)過(guo)數年才會導(dao)致損(sun)(sun)傷部位徹底(di)擊(ji)穿形成(cheng)(cheng)故(gu)障，有時破(po)壞(huai)相對比較嚴重(zhong)的(de)可(ke)能會發(fa)(fa)生短路故(gu)障，直接影(ying)響到用電(dian)(dian)(dian)單位的(de)安(an)全。

電線電纜行業，是一個很傳統的行業，幾乎含量不高，行業入門檻比較低，導致大量競爭者出現，從而非標產品遍布我大江南北，同時電纜行業又是一個靠關系，靠人脈的行業，因為電纜行業牽扯資金量大，所以又有賬期，賒賬，押款問題，人生地不熟的生意不能做，除非一手交錢一手交貨。沒有人脈沒有關系的也不要做，因為低壓無鹵電線電纜不(bu)(bu)(bu)想日用(yong)(yong)品(pin)誰都得用(yong)(yong)，更(geng)不(bu)(bu)(bu)是(shi)開(kai)在小區門(men)口就有客(ke)流量的(de)行(xing)(xing)業。第一，對(dui)電纜知識深(shen)入了解，每一個產品(pin)的(de)規格(ge)和(he)型(xing)號，以及不(bu)(bu)(bu)同(tong)的(de)用(yong)(yong)途等第二，了解行(xing)(xing)業，電纜行(xing)(xing)業最(zui)明(ming)顯的(de)特(te)點(dian)就是(shi)非(fei)標(biao)(biao)線(xian)(xian)橫行(xing)(xing)，這點(dian)很重要，同(tong)時知道(dao)國(guo)標(biao)(biao)線(xian)(xian)和(he)非(fei)標(biao)(biao)線(xian)(xian)的(de)區別第三(san)，如(ru)(ru)果(guo)你做的(de)是(shi)國(guo)標(biao)(biao)線(xian)(xian)，那你就得知道(dao)你國(guo)標(biao)(biao)線(xian)(xian)和(he)非(fei)標(biao)(biao)線(xian)(xian)比較(jiao)起來優勢(shi)(shi)是(shi)什么(me)劣勢(shi)(shi)是(shi)什么(me)，否則的(de)話，比價(jia)格(ge)，你根本比不(bu)(bu)(bu)上非(fei)標(biao)(biao)的(de).第四，了解渠道(dao)，你的(de)客(ke)戶在哪里(li)？去(qu)哪里(li)才能找到(dao)你的(de)客(ke)戶？是(shi)跑建材市場(chang)還是(shi)工(gong)地？如(ru)(ru)何才能找到(dao)競(jing)爭不(bu)(bu)(bu)是(shi)很激烈的(de)市場(chang)？

江蘇低壓無鹵電線廠家我(wo)國(guo)阻燃(ran)(ran)和耐(nai)火(huo)(huo)電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)(de)研(yan)究(jiu)(jiu)開(kai)發始(shi)于1982年。經過(guo)5年時間，即198年，許多(duo)電(dian)(dian)(dian)(dian)纜(lan)(lan)廠家已投(tou)入生產并為(wei)用(yong)戶所(suo)認同(tong)。針對(dui)(dui)當時對(dui)(dui)燃(ran)(ran)燒(shao)(shao)特性的(de)(de)命名和型(xing)(xing)(xing)(xing)(xing)號(hao)(hao)比較混亂的(de)(de)情況，筆者提出以燃(ran)(ran)燒(shao)(shao)試驗方法相(xiang)(xiang)對(dui)(dui)應的(de)(de)電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)(lan)燃(ran)(ran)燒(shao)(shao)特性，對(dui)(dui)防(fang)火(huo)(huo)電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)(lan)進(jin)行分類(lei)，用(yong)漢語(yu)拼音的(de)(de)首位字(zi)母定型(xing)(xing)(xing)(xing)(xing)作為(wei)相(xiang)(xiang)應普通電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)(lan)型(xing)(xing)(xing)(xing)(xing)號(hao)(hao)的(de)(de)前綴。其中阻燃(ran)(ran)電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)(lan)類(lei)的(de)(de)型(xing)(xing)(xing)(xing)(xing)號(hao)(hao)ZR和耐(nai)火(huo)(huo)電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)(lan)類(lei)的(de)(de)型(xing)(xing)(xing)(xing)(xing)號(hao)(hao)NH已沿用(yong)至今。隨(sui)著防(fang)火(huo)(huo)電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)(lan)在(zai)開(kai)發研(yan)究(jiu)(jiu)中所(suo)取(qu)得的(de)(de)許多(duo)新進(jin)展，原(yuan)有型(xing)(xing)(xing)(xing)(xing)號(hao)(hao)已不(bu)敷使(shi)用(yong)。加之投(tou)產廠家越來越多(duo)，在(zai)制訂企業標(biao)準(zhun)時，對(dui)(dui)有關(guan)型(xing)(xing)(xing)(xing)(xing)號(hao)(hao)各(ge)取(qu)所(suo)需，又造成新的(de)(de)混亂。最突出的(de)(de)表(biao)現是，電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)(de)燃(ran)(ran)燒(shao)(shao)特性相(xiang)(xiang)同(tong)，但名稱(cheng)和型(xing)(xing)(xing)(xing)(xing)號(hao)(hao)卻不(bu)同(tong)。業內及用(yong)戶強烈要求(qiu)改變這個狀況，希望對(dui)(dui)型(xing)(xing)(xing)(xing)(xing)號(hao)(hao)予以統一。為(wei)此(ci)，本文提出防(fang)火(huo)(huo)電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)(lan)型(xing)(xing)(xing)(xing)(xing)號(hao)(hao)的(de)(de)編制方法，供(gong)日后(hou)編制企業標(biao)準(zhun)或行業標(biao)準(zhun)參考(kao)。
