北京上原材料價格不斷上漲，近幾年行業市場假冒偽劣、粗制濫造、偷工減料、以次充好現象屢禁不止，不僅埋下了巨大的安全隱患，也導致部分依法生產的企業及經銷商步履維艱。同時，外資企業一直稱霸高端市場，擁有的競爭優勢，給國內電線電纜企業造成了巨大的經營壓力。目前，中國線纜企業數量已突破一萬大關，且大部分是民營企業，市場競爭激烈可想而知。線纜產品良莠不齊，質量出現問題與企業自身有很大關系，因此，企業加大原輔材料采購質量控制力度，注重行業技術創新，提升產品質量。另外，亂象叢生的行業市場，不僅僅是軟電纜線線(xian)纜(lan)企(qi)業自身(shen)原因造(zao)成的，與的政(zheng)治體制和(he)經(jing)濟發(fa)展政(zheng)策缺失也(ye)有著莫大的關聯(lian)。線(xian)纜(lan)行業要(yao)想突破迎來新(xin)生(sheng)，就需要(yao)政(zheng)府和(he)企(qi)業共同探討，制定統一(yi)的產品標準、規范質量(liang)、統一(yi)價格(ge)，以改變低(di)價中(zhong)標、質量(liang)薄弱的市場現(xian)狀。行業專家(jia)建議，中(zhong)國(guo)(guo)線(xian)纜(lan)企(qi)業不能(neng)一(yi)味地要(yao)追求(qiu)量(liang)的擴張，更(geng)要(yao)注重質的提高，加強在(zai)技術、資金、管理(li)(li)等方面的合作交流，引入先進(jin)技術和(he)管理(li)(li)理(li)(li)念，使企(qi)業實力得到快速提升(sheng)，增強國(guo)(guo)際競爭力。

為從根本上整治“問題軟電纜線電(dian)纜(lan)”，聯(lian)合調查(cha)組建(jian)議：首先，徹底對“問(wen)題電(dian)纜(lan)”進行(xing)清查(cha)，全(quan)面(mian)排查(cha)“問(wen)題電(dian)纜(lan)”在庫(ku)、在用情況和采購(gou)合同情況，逐一清查(cha)。發(fa)現在庫(ku)的(de)立(li)即(ji)封(feng)存(cun)，在施(shi)工的(de)一律先停用再處理，已訂立(li)采購(gou)合同的(de)立(li)即(ji)終止合同。對已經(jing)投入使用的(de)，進行(xing)檢測和風(feng)險評估，對有安全(quan)隱患(huan)的(de)產品(pin)，要在確保(bao)項目運行(xing)安全(quan)的(de)前提(ti)下積極整改、堅決撤換。據了解，相(xiang)關(guan)項目的(de)“問(wen)題電(dian)纜(lan)”拆除工作正在緊張進行(xing)。

線鼻子之所以比直徑要大，主要是為了軟電纜線報價降低連接(jie)處的(de)接(jie)觸電(dian)阻(zu)及加強局部散(san)熱能力，對于(yu)一根導線(xian)(xian)來說，整體電(dian)阻(zu)是(shi)(shi)均勻(yun)分布的(de)，但線(xian)(xian)鼻(bi)(bi)子的(de)連接(jie)處無論你用多大(da)的(de)壓力安(an)裝，其接(jie)觸部位的(de)電(dian)阻(zu)總是(shi)(shi)要(yao)大(da)于(yu)導線(xian)(xian)非連接(jie)處，從而造成局部發熱嚴重，解決的(de)辦(ban)法就是(shi)(shi)盡量(liang)增大(da)接(jie)觸面積，減少接(jie)觸電(dian)阻(zu)。同(tong)時，較大(da)的(de)線(xian)(xian)鼻(bi)(bi)子其散(san)熱能力也將更(geng)高。線(xian)(xian)耳一般(ban)要(yao)比電(dian)纜(lan)大(da)兩(liang)個規格(ge)左右，因為電(dian)纜(lan)有時候是(shi)(shi)壓成扇型的(de)，不是(shi)(shi)純圓形(xing)，一般(ban)需(xu)要(yao)用液壓機(ji)再壓緊后使用。

專業生產軟電纜線報價數字萬用(yong)表法(fa)：首先把具有斷(duan)點(dian)的電(dian)纜的一端接在220V火(huo)(huo)線，另一端使之懸空(kong)。調動萬用(yong)表的檔(dang)位(wei)使之打到交流2V電(dian)壓擋。然后從故障(zhang)(zhang)電(dian)纜的火(huo)(huo)線接入端開始，一只手緊握黑(hei)表筆，紅(hong)表筆沿著(zhu)故障(zhang)(zhang)電(dian)纜的絕緣層緩慢滑動。電(dian)纜無斷(duan)點(dian)處(chu)的電(dian)壓值大(da)約為(wei)(wei)0.445V左右。當紅(hong)表筆移(yi)動到某處(chu)時(shi)，萬用(yong)表顯示的電(dian)壓值驟降為(wei)(wei)正常電(dian)壓的1/10即0.04V時(shi)。此時(shi)基本(ben)可以斷(duan)定斷(duan)點(dian)處(chu)在該位(wei)置(zhi)向前（火(huo)(huo)線接入端）15cm處(chu)。

近年來國家大力進行城市電網建設、軟電纜線農網(wang)(wang)改造及(ji)城市(shi)軌道交通的(de)(de)(de)(de)建設，頒(ban)布了若干利好政策(ce)。這些行業(ye)的(de)(de)(de)(de)發展(zhan)(zhan)(zhan)將(jiang)為上(shang)游電(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)纜生(sheng)產(chan)企業(ye)帶(dai)來(lai)大(da)(da)量的(de)(de)(de)(de)訂單。同(tong)時，由(you)于(yu)因(yin)電(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)纜質量原(yuan)(yuan)因(yin)導致的(de)(de)(de)(de)火災居高不下，為防(fang)止(zhi)重(zhong)大(da)(da)事故的(de)(de)(de)(de)再次發生(sheng)，國(guo)(guo)(guo)(guo)家(jia)(jia)在(zai)電(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)纜行業(ye)和(he)產(chan)品標準(zhun)方(fang)面的(de)(de)(de)(de)管控越來(lai)越嚴格，新(xin)的(de)(de)(de)(de)技(ji)術標準(zhun)不斷出臺。電(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)纜產(chan)品的(de)(de)(de)(de)成本中原(yuan)(yuan)材料(liao)(liao)的(de)(de)(de)(de)比重(zhong)在(zai)80%左右，包括銅(tong)、鋁和(he)塑料(liao)(liao)等，據相關測算，原(yuan)(yuan)材料(liao)(liao)價格每(mei)上(shang)漲(zhang)(zhang)5%，相當于(yu)利潤減少4%。銅(tong)和(he)鋁是電(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)纜生(sheng)產(chan)最重(zhong)要(yao)的(de)(de)(de)(de)原(yuan)(yuan)材料(liao)(liao)，他們價格的(de)(de)(de)(de)漲(zhang)(zhang)跌，決定著(zhu)電(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)纜企業(ye)的(de)(de)(de)(de)利潤。同(tong)時，從目(mu)前我國(guo)(guo)(guo)(guo)銅(tong)需(xu)(xu)求(qiu)的(de)(de)(de)(de)結(jie)構(gou)來(lai)看，電(dian)(dian)力(li)工(gong)業(ye)所占份(fen)額最大(da)(da)，超(chao)(chao)過(guo)50%，主要(yao)用(yong)于(yu)電(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)纜、變壓器、開關、連(lian)接件(jian)等。其中電(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)纜對銅(tong)的(de)(de)(de)(de)需(xu)(xu)求(qiu)量占電(dian)(dian)力(li)工(gong)業(ye)的(de)(de)(de)(de)90%以上(shang)。因(yin)此，電(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)纜行業(ye)的(de)(de)(de)(de)發展(zhan)(zhan)(zhan)無(wu)疑也將(jiang)影響到銅(tong)的(de)(de)(de)(de)需(xu)(xu)求(qiu)量和(he)價格。國(guo)(guo)(guo)(guo)家(jia)(jia)電(dian)(dian)網(wang)(wang)在(zai)2014年(nian)(nian)5月首次提出中國(guo)(guo)(guo)(guo)經(jing)濟新(xin)常態，目(mu)前政策(ce)有利于(yu)特高壓建設，國(guo)(guo)(guo)(guo)家(jia)(jia)電(dian)(dian)網(wang)(wang)2015年(nian)(nian)規(gui)劃(hua)的(de)(de)(de)(de)13條線(xian)(xian)(xian)路(lu)預計(ji)能(neng)夠拉動(dong)超(chao)(chao)過(guo)3000億元的(de)(de)(de)(de)投資，另外國(guo)(guo)(guo)(guo)家(jia)(jia)電(dian)(dian)網(wang)(wang)也借助"一帶(dai)一路(lu)"推動(dong)特高壓建設，因(yin)此未(wei)來(lai)五(wu)年(nian)(nian)會是特高壓行業(ye)的(de)(de)(de)(de)黃金發展(zhan)(zhan)(zhan)周期(qi)，電(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)纜企業(ye)也將(jiang)獲益豐厚。近(jin)日，國(guo)(guo)(guo)(guo)外知名研究網(wang)(wang)站報道，未(wei)來(lai)5年(nian)(nian)，中國(guo)(guo)(guo)(guo)將(jiang)進(jin)入超(chao)(chao)高壓發展(zhan)(zhan)(zhan)的(de)(de)(de)(de)黃金時代(dai)，這使(shi)中國(guo)(guo)(guo)(guo)的(de)(de)(de)(de)電(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)纜市(shi)場以8-9%的(de)(de)(de)(de)年(nian)(nian)增率發展(zhan)(zhan)(zhan)。
