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，因為膠質線電纜不(bu)想日用品(pin)誰(shui)都得(de)用，更不(bu)是(shi)開在小區(qu)門口就有客(ke)流量的(de)(de)行業。第(di)(di)一(yi)，對(dui)電纜知識深入了解，每一(yi)個產品(pin)的(de)(de)規格和(he)型號，以及不(bu)同的(de)(de)用途(tu)等(deng)第(di)(di)二(er)，了解行業，電纜行業最明顯的(de)(de)特點就是(shi)非標線(xian)橫(heng)行，這(zhe)點很重(zhong)要，同時知道(dao)國標線(xian)和(he)非標線(xian)的(de)(de)區(qu)別第(di)(di)三，如(ru)果(guo)你(ni)做的(de)(de)是(shi)國標線(xian)，那你(ni)就得(de)知道(dao)你(ni)國標線(xian)和(he)非標線(xian)比較起來優(you)勢(shi)是(shi)什么劣勢(shi)是(shi)什么，否則(ze)的(de)(de)話，比價格，你(ni)根本(ben)比不(bu)上非標的(de)(de).第(di)(di)四，了解渠道(dao)，你(ni)的(de)(de)客(ke)戶在哪(na)里(li)？去哪(na)里(li)才能找到(dao)你(ni)的(de)(de)客(ke)戶？是(shi)跑建材市(shi)場(chang)還(huan)是(shi)工地？如(ru)何才能找到(dao)競爭不(bu)是(shi)很激烈的(de)(de)市(shi)場(chang)？

江蘇阻燃的膠質線電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)故(gu)(gu)(gu)障類型有(you)(you)以下幾個方面(mian)：開(kai)路(lu)故(gu)(gu)(gu)障，這(zhe)類故(gu)(gu)(gu)障通常是(shi)指電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)與(yu)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)間或(huo)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)對地的(de)(de)電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)值(zhi)在(zai)規定值(zhi)范圍內，但(dan)(dan)實際工作電(dian)(dian)(dian)(dian)(dian)壓無法向(xiang)終(zhong)端傳輸(shu)或(huo)雖然也有(you)(you)部分電(dian)(dian)(dian)(dian)(dian)壓傳輸(shu)到終(zhong)端，但(dan)(dan)幾乎沒有(you)(you)負載能力，這(zhe)些(xie)都屬于開(kai)路(lu)故(gu)(gu)(gu)障，在(zai)實際生產中，我(wo)們見到的(de)(de)斷線(xian)故(gu)(gu)(gu)障屬于一種(zhong)(zhong)特殊的(de)(de)開(kai)路(lu)故(gu)(gu)(gu)障。低阻(zu)(zu)故(gu)(gu)(gu)障，當電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)與(yu)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)間的(de)(de)絕(jue)緣(yuan)有(you)(you)損壞(huai)現(xian)象或(huo)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)對地的(de)(de)絕(jue)緣(yuan)有(you)(you)損壞(huai)現(xian)象時，電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)絕(jue)緣(yuan)電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)必然會(hui)減小，在(zai)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)絕(jue)緣(yuan)電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)比十倍電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)特性(xing)阻(zu)(zu)抗還要小的(de)(de)情況下，我(wo)們稱這(zhe)種(zhong)(zhong)故(gu)(gu)(gu)障為低阻(zu)(zu)故(gu)(gu)(gu)障。在(zai)測量低阻(zu)(zu)故(gu)(gu)(gu)障時，可用(yong)(yong)低壓脈(mo)沖反(fan)射法。高阻(zu)(zu)故(gu)(gu)(gu)障，當電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)與(yu)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)間或(huo)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)對地的(de)(de)絕(jue)緣(yuan)電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)比正常值(zhi)低很多，但(dan)(dan)比十倍電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)特性(xing)阻(zu)(zu)抗大時，我(wo)們把這(zhe)種(zhong)(zhong)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)故(gu)(gu)(gu)障稱作高阻(zu)(zu)故(gu)(gu)(gu)障。對高阻(zu)(zu)故(gu)(gu)(gu)障的(de)(de)測量，不(bu)能使用(yong)(yong)低壓脈(mo)沖反(fan)射法，按照高阻(zu)(zu)故(gu)(gu)(gu)障具體性(xing)質的(de)(de)不(bu)同，又可把高阻(zu)(zu)故(gu)(gu)(gu)障的(de)(de)性(xing)質分為泄漏性(xing)與(yu)閃絡性(xing)兩種(zhong)(zhong)。

首先是針對防火特性上，不管是柔性的YTTW礦物電纜還是剛性的BTTZ電纜，兩者的存在都是為了保證電纜在一定的火焰以及高溫下能夠保證電纜的正常運作，所以它們的防火性能都是極為不錯的。但是從高溫的狀態來講，柔性的YTTW礦物電纜能夠承受的極限溫度為1083攝氏度，而剛性BTTZ電纜只有1000攝氏度，并且柔性YTTW礦物電纜能夠在950在1000攝氏度高溫中運行3小時，BTTZ電纜只能維持半小時而已。然后是區分電纜的制作長度，因為工藝特性原因。YTTW礦物電纜因為比較柔和一些，在制作的時候能夠將其長度膠質線延伸1000米都是(shi)沒有(you)問題的，而剛性(xing)BTTZ電纜(lan)需(xu)要考慮過(guo)長(chang)(chang)的電纜(lan)不易存(cun)放，并(bing)且(qie)不容易生(sheng)產制作(zuo)，所以YTTW礦物電纜(lan)能夠避免長(chang)(chang)度(du)要求的規(gui)范，不用(yong)擔心(xin)使用(yong)的時(shi)候長(chang)(chang)度(du)不足使用(yong)接(jie)口。

1. 看電纜電線長度：江蘇阻燃的膠質線國家(jia)(jia)標準規定，電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜每卷(juan)100米，計量(liang)誤差不大于0.5%，也(ye)(ye)就是(shi)每卷(juan)線(xian)(xian)的(de)(de)(de)(de)(de)長(chang)度為100±0.5米，但(dan)(dan)是(shi)有些(xie)(xie)商家(jia)(jia)標注的(de)(de)(de)(de)(de)是(shi)100±20米，但(dan)(dan)實際(ji)上，卻(que)只有80米左右。2. 看(kan)電(dian)(dian)(dian)阻值：電(dian)(dian)(dian)阻值超標的(de)(de)(de)(de)(de)話，電(dian)(dian)(dian)線(xian)(xian)就容(rong)易(yi)出現溫(wen)度過高、老(lao)(lao)化(hua)(hua)的(de)(de)(de)(de)(de)危險，而且如果電(dian)(dian)(dian)線(xian)(xian)短路的(de)(de)(de)(de)(de)話，還(huan)會引發(fa)(fa)火災。并且電(dian)(dian)(dian)阻值超標，還(huan)增加傳輸電(dian)(dian)(dian)量(liang)時的(de)(de)(de)(de)(de)消耗，增加電(dian)(dian)(dian)費，所以，我們在(zai)選擇(ze)時，一定要(yao)留意這一點。3.看(kan)原材料(liao)(liao)：純(chun)銅(tong)芯的(de)(de)(de)(de)(de)材料(liao)(liao)導電(dian)(dian)(dian)性好，而且不易(yi)老(lao)(lao)化(hua)(hua)，更加耐(nai)用(yong)(yong)，也(ye)(ye)減少(shao)了故障發(fa)(fa)生。但(dan)(dan)是(shi)有些(xie)(xie)商家(jia)(jia)，會在(zai)銅(tong)材質(zhi)(zhi)中添加一些(xie)(xie)雜質(zhi)(zhi)銅(tong)、回收(shou)銅(tong)，還(huan)有的(de)(de)(de)(de)(de)劣質(zhi)(zhi)產品通過降低(di)銅(tong)芯實際(ji)截面積，來減少(shao)銅(tong)材質(zhi)(zhi)的(de)(de)(de)(de)(de)用(yong)(yong)量(liang)，這樣容(rong)易(yi)導致電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜用(yong)(yong)電(dian)(dian)(dian)過程中發(fa)(fa)熱，損壞外邊的(de)(de)(de)(de)(de)絕緣層塑料(liao)(liao)，容(rong)易(yi)讓電(dian)(dian)(dian)線(xian)(xian)老(lao)(lao)化(hua)(hua)，導致出現漏(lou)電(dian)(dian)(dian)、短路的(de)(de)(de)(de)(de)問題。
