廣西專業生產鋁芯電纜廠家近年來，伴隨(sui)著我(wo)(wo)國(guo)(guo)(guo)(guo)(guo)經濟的快速增長以(yi)及(ji)工業(ye)(ye)化、城鎮(zhen)化進程的加快，我(wo)(wo)國(guo)(guo)(guo)(guo)(guo)電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)(lan)行(xing)業(ye)(ye)發展迅(xun)猛，?早于?2011?年我(wo)(wo)國(guo)(guo)(guo)(guo)(guo)電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)(lan)制造(zao)業(ye)(ye)的產(chan)(chan)值就(jiu)已超過(guo)美(mei)國(guo)(guo)(guo)(guo)(guo)，躍居(ju)全球(qiu)第一(yi)，國(guo)(guo)(guo)(guo)(guo)內市場產(chan)(chan)品品種(zhong)滿足率達?95%以(yi)上(shang)。但現階(jie)段(duan)粗(cu)放式(shi)生(sheng)產(chan)(chan)仍是我(wo)(wo)國(guo)(guo)(guo)(guo)(guo)電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)(lan)行(xing)業(ye)(ye)的主流，仍然(ran)存在較(jiao)為(wei)突出的結(jie)構失衡問題(ti)，即普通電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)(lan)產(chan)(chan)品供過(guo)于求(qiu)，而高端產(chan)(chan)品供不應求(qiu)。我(wo)(wo)國(guo)(guo)(guo)(guo)(guo)是世界電(dian)(dian)(dian)(dian)纜(lan)(lan)第一(yi)制造(zao)大國(guo)(guo)(guo)(guo)(guo)，但產(chan)(chan)業(ye)(ye)發展還(huan)不成(cheng)熟、重量(liang)輕質，產(chan)(chan)業(ye)(ye)集中度(du)低(di)，科研投入不足，創新能力較(jiao)弱，與國(guo)(guo)(guo)(guo)(guo)外先(xian)進國(guo)(guo)(guo)(guo)(guo)家相比(bi)仍存在較(jiao)大差距，提(ti)升質量(liang)將成(cheng)為(wei)行(xing)業(ye)(ye)今后發展的主要(yao)方向。國(guo)(guo)(guo)(guo)(guo)際(ji)(ji)上(shang)對電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)(lan)產(chan)(chan)業(ye)(ye)的產(chan)(chan)量(liang)及(ji)消費量(liang)的分(fen)析，一(yi)般(ban)以(yi)銅芯絕緣電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)(lan)為(wei)主，并分(fen)為(wei)動(dong)力電(dian)(dian)(dian)(dian)纜(lan)(lan)、通信(xin)電(dian)(dian)(dian)(dian)纜(lan)(lan)和繞(rao)組線三大類(與國(guo)(guo)(guo)(guo)(guo)內習慣分(fen)類有所(suo)不同)，采(cai)(cai)用(yong)以(yi)美(mei)元(yuan)為(wei)價(jia)(jia)值計量(liang)單(dan)位或以(yi)銅導體消耗(hao)量(liang)(重量(liang))為(wei)主要(yao)統(tong)計單(dan)位，由于價(jia)(jia)值量(liang)的數(shu)據包含了不同時期的通貨(huo)膨脹(zhang)率以(yi)及(ji)材(cai)料價(jia)(jia)格(ge)(ge)的變(bian)動(dong)，因此采(cai)(cai)用(yong)銅導體消耗(hao)量(liang)的分(fen)析排除了導體價(jia)(jia)格(ge)(ge)變(bian)動(dong)的因素，相對而言比(bi)較(jiao)接(jie)近實(shi)際(ji)(ji)的變(bian)化趨(qu)勢(shi)。

線鼻子之所以比直徑要大，主要是為了鋁芯電纜廠家降低連接(jie)處(chu)的(de)(de)(de)接(jie)觸(chu)(chu)電(dian)(dian)阻(zu)及(ji)加強局(ju)部(bu)散(san)熱(re)能力，對于(yu)一根導(dao)線(xian)來說，整體電(dian)(dian)阻(zu)是均勻分布的(de)(de)(de)，但線(xian)鼻(bi)子的(de)(de)(de)連接(jie)處(chu)無(wu)論你用多大(da)(da)的(de)(de)(de)壓力安(an)裝，其接(jie)觸(chu)(chu)部(bu)位的(de)(de)(de)電(dian)(dian)阻(zu)總(zong)是要(yao)大(da)(da)于(yu)導(dao)線(xian)非(fei)連接(jie)處(chu)，從(cong)而造(zao)成局(ju)部(bu)發(fa)熱(re)嚴重，解決的(de)(de)(de)辦法就是盡量增大(da)(da)接(jie)觸(chu)(chu)面(mian)積，減(jian)少(shao)接(jie)觸(chu)(chu)電(dian)(dian)阻(zu)。同時，較大(da)(da)的(de)(de)(de)線(xian)鼻(bi)子其散(san)熱(re)能力也將更高(gao)。線(xian)耳一般要(yao)比電(dian)(dian)纜大(da)(da)兩個(ge)規格左右，因為電(dian)(dian)纜有時候是壓成扇型的(de)(de)(de)，不是純圓(yuan)形(xing)，一般需(xu)要(yao)用液壓機再壓緊(jin)后使用。
