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，因為耐火花線電(dian)纜不想日用(yong)品(pin)(pin)誰都得用(yong)，更不是(shi)(shi)開在(zai)小(xiao)區門口就(jiu)有客流量的(de)(de)行(xing)業(ye)。第一(yi)，對電(dian)纜知(zhi)識深入了解(jie)，每一(yi)個(ge)產品(pin)(pin)的(de)(de)規(gui)格和(he)型號，以及不同(tong)的(de)(de)用(yong)途等(deng)第二，了解(jie)行(xing)業(ye)，電(dian)纜行(xing)業(ye)最明(ming)顯的(de)(de)特點就(jiu)是(shi)(shi)非標(biao)線(xian)(xian)(xian)橫行(xing)，這點很(hen)重(zhong)要，同(tong)時知(zhi)道(dao)國(guo)(guo)標(biao)線(xian)(xian)(xian)和(he)非標(biao)線(xian)(xian)(xian)的(de)(de)區別第三，如果你(ni)做的(de)(de)是(shi)(shi)國(guo)(guo)標(biao)線(xian)(xian)(xian)，那你(ni)就(jiu)得知(zhi)道(dao)你(ni)國(guo)(guo)標(biao)線(xian)(xian)(xian)和(he)非標(biao)線(xian)(xian)(xian)比較起(qi)來優勢是(shi)(shi)什么劣(lie)勢是(shi)(shi)什么，否則的(de)(de)話，比價格，你(ni)根本比不上非標(biao)的(de)(de).第四(si)，了解(jie)渠道(dao)，你(ni)的(de)(de)客戶在(zai)哪(na)里？去哪(na)里才能找到(dao)你(ni)的(de)(de)客戶？是(shi)(shi)跑(pao)建材市場(chang)還是(shi)(shi)工地(di)？如何才能找到(dao)競爭不是(shi)(shi)很(hen)激烈的(de)(de)市場(chang)？

由于我國的耐火花線電線(xian)(xian)電纜(lan)(lan)(lan)行(xing)(xing)業(ye)準入門檻較低，低水平重復建(jian)設現(xian)象嚴重，加(jia)(jia)上原(yuan)材(cai)料價(jia)(jia)格不斷上漲，近幾年行(xing)(xing)業(ye)市場假冒(mao)偽劣(lie)、粗(cu)制濫造、偷工減料、以(yi)次(ci)充(chong)好現(xian)象屢(lv)禁(jin)不止(zhi)，不僅(jin)埋下了(le)巨大(da)的(de)(de)(de)(de)安全隱患，也導致(zhi)部(bu)分(fen)依法(fa)生(sheng)(sheng)產(chan)(chan)的(de)(de)(de)(de)企(qi)(qi)業(ye)及經銷商步履維艱。同時(shi)，外(wai)資(zi)企(qi)(qi)業(ye)一直稱霸(ba)高(gao)端市場，擁(yong)有的(de)(de)(de)(de)競爭優勢，給國內電線(xian)(xian)電纜(lan)(lan)(lan)企(qi)(qi)業(ye)造成了(le)巨大(da)的(de)(de)(de)(de)經營(ying)壓(ya)力。目前，中(zhong)國線(xian)(xian)纜(lan)(lan)(lan)企(qi)(qi)業(ye)數量已突破一萬大(da)關(guan)(guan)，且大(da)部(bu)分(fen)是(shi)民(min)營(ying)企(qi)(qi)業(ye)，市場競爭激烈可(ke)想而知。線(xian)(xian)纜(lan)(lan)(lan)產(chan)(chan)品(pin)(pin)良莠不齊，質(zhi)量出現(xian)問題與(yu)企(qi)(qi)業(ye)自身(shen)(shen)有很(hen)大(da)關(guan)(guan)系，因此(ci)，企(qi)(qi)業(ye)加(jia)(jia)大(da)原(yuan)輔材(cai)料采購質(zhi)量控制力度(du)，注(zhu)重行(xing)(xing)業(ye)技術創新，提(ti)升產(chan)(chan)品(pin)(pin)質(zhi)量。另外(wai)，亂象叢生(sheng)(sheng)的(de)(de)(de)(de)行(xing)(xing)業(ye)市場，不僅(jin)僅(jin)是(shi)線(xian)(xian)纜(lan)(lan)(lan)企(qi)(qi)業(ye)自身(shen)(shen)原(yuan)因造成的(de)(de)(de)(de)，與(yu)的(de)(de)(de)(de)政(zheng)治體制和經濟發展政(zheng)策缺失也有著莫大(da)的(de)(de)(de)(de)關(guan)(guan)聯。線(xian)(xian)纜(lan)(lan)(lan)行(xing)(xing)業(ye)要(yao)想突破迎來新生(sheng)(sheng)，就需要(yao)政(zheng)府和企(qi)(qi)業(ye)共同探討，制定統一的(de)(de)(de)(de)產(chan)(chan)品(pin)(pin)標準、規范質(zhi)量、統一價(jia)(jia)格，以(yi)改變低價(jia)(jia)中(zhong)標、質(zhi)量薄弱(ruo)的(de)(de)(de)(de)市場現(xian)狀。行(xing)(xing)業(ye)專家建(jian)議，中(zhong)國線(xian)(xian)纜(lan)(lan)(lan)企(qi)(qi)業(ye)不能一味地要(yao)追求量的(de)(de)(de)(de)擴張(zhang)，更要(yao)注(zhu)重質(zhi)的(de)(de)(de)(de)提(ti)高(gao)，加(jia)(jia)強在技術、資(zi)金(jin)、管理(li)(li)等(deng)方(fang)面(mian)的(de)(de)(de)(de)合作交流，引入先(xian)進(jin)技術和管理(li)(li)理(li)(li)念(nian)，使企(qi)(qi)業(ye)實(shi)力得到快速提(ti)升，增(zeng)強國際競爭力。
