近年來國家大力進行城市電網建設、膠質線農網(wang)(wang)(wang)改(gai)造及城市軌道交(jiao)通的(de)(de)(de)(de)(de)建設，頒布了若干利好政策(ce)。這些行(xing)業(ye)(ye)的(de)(de)(de)(de)(de)發展將(jiang)(jiang)為上(shang)游電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)(dian)纜(lan)生(sheng)產(chan)(chan)企(qi)業(ye)(ye)帶來(lai)大(da)量的(de)(de)(de)(de)(de)訂單。同時(shi)，由于(yu)(yu)因(yin)電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)(dian)纜(lan)質(zhi)量原(yuan)因(yin)導致的(de)(de)(de)(de)(de)火(huo)災居高(gao)不下，為防止重(zhong)大(da)事故的(de)(de)(de)(de)(de)再次(ci)發生(sheng)，國(guo)家在(zai)電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)(dian)纜(lan)行(xing)業(ye)(ye)和(he)產(chan)(chan)品(pin)標(biao)準方(fang)面的(de)(de)(de)(de)(de)管控越(yue)來(lai)越(yue)嚴(yan)格，新的(de)(de)(de)(de)(de)技術標(biao)準不斷出(chu)臺。電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)(dian)纜(lan)產(chan)(chan)品(pin)的(de)(de)(de)(de)(de)成本(ben)中原(yuan)材料(liao)的(de)(de)(de)(de)(de)比重(zhong)在(zai)80%左右(you)，包(bao)括銅(tong)、鋁(lv)和(he)塑料(liao)等(deng)，據相關測(ce)算，原(yuan)材料(liao)價格每上(shang)漲5%，相當于(yu)(yu)利潤減(jian)少4%。銅(tong)和(he)鋁(lv)是電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)(dian)纜(lan)生(sheng)產(chan)(chan)最重(zhong)要的(de)(de)(de)(de)(de)原(yuan)材料(liao)，他們價格的(de)(de)(de)(de)(de)漲跌，決定著電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)(dian)纜(lan)企(qi)業(ye)(ye)的(de)(de)(de)(de)(de)利潤。同時(shi)，從目前(qian)我(wo)國(guo)銅(tong)需求(qiu)的(de)(de)(de)(de)(de)結構來(lai)看，電(dian)(dian)(dian)(dian)力工業(ye)(ye)所占份額(e)最大(da)，超(chao)過(guo)50%，主(zhu)要用(yong)于(yu)(yu)電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)(dian)纜(lan)、變壓器、開關、連接(jie)件(jian)等(deng)。其中電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)(dian)纜(lan)對(dui)銅(tong)的(de)(de)(de)(de)(de)需求(qiu)量占電(dian)(dian)(dian)(dian)力工業(ye)(ye)的(de)(de)(de)(de)(de)90%以上(shang)。因(yin)此(ci)，電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)(dian)纜(lan)行(xing)業(ye)(ye)的(de)(de)(de)(de)(de)發展無疑也(ye)將(jiang)(jiang)影響到銅(tong)的(de)(de)(de)(de)(de)需求(qiu)量和(he)價格。國(guo)家電(dian)(dian)(dian)(dian)網(wang)(wang)(wang)在(zai)2014年(nian)(nian)5月首次(ci)提出(chu)中國(guo)經(jing)濟新常態，目前(qian)政策(ce)有利于(yu)(yu)特(te)高(gao)壓建設，國(guo)家電(dian)(dian)(dian)(dian)網(wang)(wang)(wang)2015年(nian)(nian)規(gui)劃(hua)的(de)(de)(de)(de)(de)13條線(xian)(xian)(xian)路預計(ji)能(neng)夠拉動超(chao)過(guo)3000億元(yuan)的(de)(de)(de)(de)(de)投資(zi)，另外(wai)國(guo)家電(dian)(dian)(dian)(dian)網(wang)(wang)(wang)也(ye)借助(zhu)"一帶一路"推動特(te)高(gao)壓建設，因(yin)此(ci)未來(lai)五(wu)年(nian)(nian)會(hui)是特(te)高(gao)壓行(xing)業(ye)(ye)的(de)(de)(de)(de)(de)黃金發展周(zhou)期(qi)，電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)(dian)纜(lan)企(qi)業(ye)(ye)也(ye)將(jiang)(jiang)獲益(yi)豐厚。近日，國(guo)外(wai)知名研究網(wang)(wang)(wang)站報道，未來(lai)5年(nian)(nian)，中國(guo)將(jiang)(jiang)進入超(chao)高(gao)壓發展的(de)(de)(de)(de)(de)黃金時(shi)代，這使中國(guo)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)(dian)纜(lan)市場以8-9%的(de)(de)(de)(de)(de)年(nian)(nian)增(zeng)率發展。
