專業生產銅芯線電(dian)(dian)纜老化原因：外力的(de)(de)損(sun)傷(shang)(shang)。由(you)近幾年的(de)(de)數(shu)據(ju)分析來看(kan)，尤其是(shi)在經濟高(gao)速發(fa)展(zhan)中(zhong)(zhong)(zhong)的(de)(de)上海，現在的(de)(de)大多(duo)數(shu)電(dian)(dian)纜故障都(dou)是(shi)因為機(ji)械損(sun)傷(shang)(shang)引(yin)起的(de)(de)。譬(pi)如：電(dian)(dian)纜在敷(fu)設(she)安(an)裝的(de)(de)過程(cheng)中(zhong)(zhong)(zhong)不按照正(zheng)常規(gui)范施(shi)工(gong)，容易(yi)(yi)造(zao)成機(ji)械損(sun)傷(shang)(shang)；在直埋(mai)電(dian)(dian)纜上建造(zao)施(shi)工(gong)也(ye)特別容易(yi)(yi)將運行中(zhong)(zhong)(zhong)的(de)(de)電(dian)(dian)纜損(sun)傷(shang)(shang)等。有時如果(guo)損(sun)傷(shang)(shang)不嚴(yan)重，要(yao)經過數(shu)年才會導(dao)致損(sun)傷(shang)(shang)部位徹底擊穿形(xing)成故障，有時破(po)壞相對比較嚴(yan)重的(de)(de)可能會發(fa)生短路故障，直接影(ying)響到用電(dian)(dian)單(dan)位的(de)(de)安(an)全。

由于我國的銅芯線電線(xian)(xian)電纜(lan)(lan)行業(ye)(ye)(ye)準(zhun)入門檻較(jiao)低，低水(shui)平重復(fu)建(jian)設(she)現(xian)(xian)(xian)象嚴重，加上原材(cai)料價(jia)格不斷上漲，近幾年行業(ye)(ye)(ye)市場假冒偽劣、粗制(zhi)(zhi)濫造(zao)、偷(tou)工減料、以次充好現(xian)(xian)(xian)象屢禁不止，不僅埋下了巨大(da)的(de)(de)(de)(de)安(an)全(quan)隱患(huan)，也(ye)導(dao)致部(bu)(bu)分依(yi)法生(sheng)產(chan)的(de)(de)(de)(de)企(qi)業(ye)(ye)(ye)及(ji)經(jing)(jing)銷(xiao)商步履維艱。同(tong)時，外資企(qi)業(ye)(ye)(ye)一(yi)直稱霸(ba)高端市場，擁有(you)的(de)(de)(de)(de)競爭優勢，給國(guo)內電線(xian)(xian)電纜(lan)(lan)企(qi)業(ye)(ye)(ye)造(zao)成了巨大(da)的(de)(de)(de)(de)經(jing)(jing)營壓力(li)。目前，中國(guo)線(xian)(xian)纜(lan)(lan)企(qi)業(ye)(ye)(ye)數量(liang)已突破(po)一(yi)萬大(da)關，且(qie)大(da)部(bu)(bu)分是民營企(qi)業(ye)(ye)(ye)，市場競爭激(ji)烈可想(xiang)而知。線(xian)(xian)纜(lan)(lan)產(chan)品(pin)良莠不齊，質量(liang)出(chu)現(xian)(xian)(xian)問題(ti)與(yu)(yu)企(qi)業(ye)(ye)(ye)自身有(you)很(hen)大(da)關系，因(yin)此，企(qi)業(ye)(ye)(ye)加大(da)原輔(fu)材(cai)料采購質量(liang)控制(zhi)(zhi)力(li)度，注(zhu)重行業(ye)(ye)(ye)技術創新，提(ti)升產(chan)品(pin)質量(liang)。另外，亂象叢生(sheng)的(de)(de)(de)(de)行業(ye)(ye)(ye)市場，不僅僅是線(xian)(xian)纜(lan)(lan)企(qi)業(ye)(ye)(ye)自身原因(yin)造(zao)成的(de)(de)(de)(de)，與(yu)(yu)的(de)(de)(de)(de)政治體制(zhi)(zhi)和(he)(he)經(jing)(jing)濟發(fa)展(zhan)政策缺失也(ye)有(you)著莫大(da)的(de)(de)(de)(de)關聯。線(xian)(xian)纜(lan)(lan)行業(ye)(ye)(ye)要想(xiang)突破(po)迎來(lai)新生(sheng)，就需要政府和(he)(he)企(qi)業(ye)(ye)(ye)共(gong)同(tong)探(tan)討，制(zhi)(zhi)定統一(yi)的(de)(de)(de)(de)產(chan)品(pin)標準(zhun)、規范質量(liang)、統一(yi)價(jia)格，以改變低價(jia)中標、質量(liang)薄(bo)弱(ruo)的(de)(de)(de)(de)市場現(xian)(xian)(xian)狀。行業(ye)(ye)(ye)專家建(jian)議，中國(guo)線(xian)(xian)纜(lan)(lan)企(qi)業(ye)(ye)(ye)不能一(yi)味地要追(zhui)求量(liang)的(de)(de)(de)(de)擴(kuo)張，更要注(zhu)重質的(de)(de)(de)(de)提(ti)高，加強在技術、資金、管理(li)等(deng)方(fang)面的(de)(de)(de)(de)合作(zuo)交流，引入先進(jin)技術和(he)(he)管理(li)理(li)念，使企(qi)業(ye)(ye)(ye)實力(li)得(de)到快速提(ti)升，增強國(guo)際競爭力(li)。
