電線電纜作為國民經濟中最大的配套行業之一，是各產業的基礎，其產品廣泛應用于電力、建筑、民用、通信、船舶、軍工、航空以及石油化工等領域。電線電纜按用途可分為電力電纜、電氣裝備電纜、繞組線、裸電線、通信電纜和電線及電纜配件，從2017年我國電線電纜行業細分市場規模占比情況來看，鋁芯線批發電(dian)(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)占據電(dian)(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)業(ye)務(wu)的(de)(de)最大部分，規模占比(bi)(bi)35.7%，其(qi)次(ci)是(shi)電(dian)(dian)(dian)(dian)(dian)氣裝(zhuang)備電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)、繞組線(xian)，分別占比(bi)(bi)20%和15.7%。近(jin)年(nian)來，我(wo)國(guo)電(dian)(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)行(xing)業(ye)保持(chi)了較快發展勢(shi)頭，作為國(guo)民經濟的(de)(de)最重要(yao)的(de)(de)支(zhi)撐產業(ye)之一，電(dian)(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)行(xing)業(ye)在(zai)中(zhong)國(guo)有著廣闊的(de)(de)市(shi)場。根據近(jin)幾年(nian)的(de)(de)情況來看(kan)，我(wo)國(guo)電(dian)(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)行(xing)業(ye)銷(xiao)(xiao)售(shou)收(shou)入總體呈現上升趨(qu)勢(shi)，其(qi)中(zhong)2016年(nian)銷(xiao)(xiao)售(shou)收(shou)入創(chuang)新(xin)高達13924億元，2017年(nian)電(dian)(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)銷(xiao)(xiao)售(shou)收(shou)入出現小(xiao)幅下降，為13513億元。隨著我(wo)國(guo)對基礎設施投(tou)入的(de)(de)加(jia)(jia)大，以(yi)及新(xin)能源、軍工、海(hai)洋工程、軌道(dao)交通、特高壓、智能電(dian)(dian)(dian)(dian)(dian)網(wang)的(de)(de)發展得到(dao)進一步貫徹落(luo)實，市(shi)場對電(dian)(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)的(de)(de)需求在(zai)不(bu)斷增強，尤其(qi)是(shi)在(zai)高端裝(zhuang)備用電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)方面，未來我(wo)國(guo)電(dian)(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)行(xing)業(ye)銷(xiao)(xiao)售(shou)收(shou)入仍將進一步增加(jia)(jia)。

線鼻子之所以比直徑要大，主要是為了鋁芯線批發降低(di)連接(jie)(jie)(jie)處的(de)(de)(de)接(jie)(jie)(jie)觸(chu)電(dian)阻及加強(qiang)局部(bu)散(san)熱能(neng)力，對于一(yi)根導(dao)線(xian)來說(shuo)，整體電(dian)阻是(shi)(shi)均勻分布的(de)(de)(de)，但線(xian)鼻(bi)子的(de)(de)(de)連接(jie)(jie)(jie)處無論你用(yong)多大的(de)(de)(de)壓力安裝，其接(jie)(jie)(jie)觸(chu)部(bu)位(wei)的(de)(de)(de)電(dian)阻總是(shi)(shi)要大于導(dao)線(xian)非(fei)連接(jie)(jie)(jie)處，從(cong)而造成(cheng)局部(bu)發熱嚴重，解(jie)決(jue)的(de)(de)(de)辦法就是(shi)(shi)盡量增大接(jie)(jie)(jie)觸(chu)面積，減少接(jie)(jie)(jie)觸(chu)電(dian)阻。同時，較大的(de)(de)(de)線(xian)鼻(bi)子其散(san)熱能(neng)力也將更(geng)高(gao)。線(xian)耳一(yi)般要比電(dian)纜大兩個規(gui)格左右，因為電(dian)纜有時候是(shi)(shi)壓成(cheng)扇型的(de)(de)(de)，不是(shi)(shi)純圓(yuan)形，一(yi)般需(xu)要用(yong)液(ye)壓機再壓緊(jin)后使用(yong)。

具有購買力的電線電纜市場需求減少。由于全球市場經濟不景氣，我國鋁芯線電(dian)(dian)線電(dian)(dian)纜(lan)(lan)市場也受到(dao)重(zhong)創(chuang)，需求量一度下落。但是進入2018年，市場由(you)于受到(dao)智網及寬帶工(gong)程建設有利(li)(li)促進，目(mu)前正在逐步恢(hui)復(fu)當中，但對電(dian)(dian)纜(lan)(lan)行(xing)業(ye)的(de)(de)利(li)(li)潤(run)緩解作用較(jiao)為(wei)有限。原(yuan)材(cai)價格(ge)(ge)不(bu)穩定(ding)，嚴重(zhong)積壓電(dian)(dian)纜(lan)(lan)行(xing)業(ye)的(de)(de)利(li)(li)潤(run)。電(dian)(dian)纜(lan)(lan)行(xing)業(ye)的(de)(de)特點是料(liao)重(zhong)工(gong)輕利(li)(li)薄，當原(yuan)材(cai)價格(ge)(ge)上(shang)漲(zhang)時(shi)，電(dian)(dian)纜(lan)(lan)企(qi)(qi)業(ye)購買原(yuan)材(cai)將(jiang)造成銀(yin)根(gen)吃緊，資金(jin)周轉(zhuan)緩慢。而當原(yuan)材(cai)價格(ge)(ge)下跌，電(dian)(dian)纜(lan)(lan)企(qi)(qi)業(ye)又(you)回因(yin)為(wei)來不(bu)及消(xiao)化原(yuan)材(cai)，而造成出廠價急速下跌。兩者(zhe)間的(de)(de)兩者(zhe)之間的(de)(de)“剪刀差”與“時(shi)間差”嚴重(zhong)擠壓了電(dian)(dian)纜(lan)(lan)企(qi)(qi)業(ye)的(de)(de)盈利(li)(li)空間。目(mu)前行(xing)業(ye)普遍比較(jiao)認可的(de)(de)說法是，原(yuan)材(cai)價格(ge)(ge)原(yuan)材(cai)料(liao)價格(ge)(ge)每(mei)上(shang)漲(zhang)5%，電(dian)(dian)纜(lan)(lan)企(qi)(qi)業(ye)的(de)(de)相(xiang)對利(li)(li)潤(run)則將(jiang)減(jian)少(shao)4%。銀(yin)行(xing)貸款利(li)(li)息(xi)的(de)(de)不(bu)斷增加，同(tong)樣給電(dian)(dian)纜(lan)(lan)企(qi)(qi)業(ye)的(de)(de)利(li)(li)潤(run)空間造成重(zhong)大(da)影響。由(you)于目(mu)前我(wo)國的(de)(de)電(dian)(dian)纜(lan)(lan)企(qi)(qi)業(ye)基(ji)本都是民(min)營企(qi)(qi)業(ye)，因(yin)此(ci)即(ji)使比較(jiao)幸運能夠帶到(dao)款，但是利(li)(li)率一般也要上(shang)浮40%左后，何況有眾多企(qi)(qi)業(ye)根(gen)本就融(rong)不(bu)到(dao)資。融(rong)資難的(de)(de)問題直(zhi)接(jie)造成我(wo)國整個電(dian)(dian)纜(lan)(lan)行(xing)業(ye)的(de)(de)資金(jin)回籠周期變慢，三角債盛行(xing)。
