近年來國家大力進行城市電網建設、軟電纜線農網(wang)改造及城市軌(gui)道交通的(de)(de)(de)(de)(de)(de)(de)(de)(de)建(jian)設(she)，頒布了若干利好(hao)政(zheng)策。這些(xie)行(xing)業(ye)的(de)(de)(de)(de)(de)(de)(de)(de)(de)發(fa)(fa)展將為上(shang)游電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)(dian)纜生(sheng)產企業(ye)帶來(lai)(lai)大(da)量的(de)(de)(de)(de)(de)(de)(de)(de)(de)訂單(dan)。同時(shi)，由于因(yin)電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)(dian)纜質(zhi)量原(yuan)(yuan)因(yin)導致的(de)(de)(de)(de)(de)(de)(de)(de)(de)火災居高(gao)(gao)不(bu)下(xia)，為防止重(zhong)大(da)事(shi)故的(de)(de)(de)(de)(de)(de)(de)(de)(de)再次發(fa)(fa)生(sheng)，國(guo)(guo)家在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)(dian)纜行(xing)業(ye)和(he)產品標準(zhun)(zhun)方(fang)面的(de)(de)(de)(de)(de)(de)(de)(de)(de)管控越(yue)來(lai)(lai)越(yue)嚴格(ge)(ge)，新的(de)(de)(de)(de)(de)(de)(de)(de)(de)技術(shu)標準(zhun)(zhun)不(bu)斷(duan)出臺。電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)(dian)纜產品的(de)(de)(de)(de)(de)(de)(de)(de)(de)成本中(zhong)原(yuan)(yuan)材(cai)料(liao)的(de)(de)(de)(de)(de)(de)(de)(de)(de)比重(zhong)在(zai)80%左右，包(bao)括銅(tong)(tong)、鋁和(he)塑(su)料(liao)等，據相(xiang)關測算，原(yuan)(yuan)材(cai)料(liao)價(jia)格(ge)(ge)每(mei)上(shang)漲5%，相(xiang)當于利潤減少4%。銅(tong)(tong)和(he)鋁是電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)(dian)纜生(sheng)產最重(zhong)要的(de)(de)(de)(de)(de)(de)(de)(de)(de)原(yuan)(yuan)材(cai)料(liao)，他們價(jia)格(ge)(ge)的(de)(de)(de)(de)(de)(de)(de)(de)(de)漲跌，決(jue)定(ding)著電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)(dian)纜企業(ye)的(de)(de)(de)(de)(de)(de)(de)(de)(de)利潤。同時(shi)，從目前(qian)我國(guo)(guo)銅(tong)(tong)需(xu)求(qiu)的(de)(de)(de)(de)(de)(de)(de)(de)(de)結構來(lai)(lai)看，電(dian)(dian)(dian)(dian)(dian)(dian)力工業(ye)所占份額(e)最大(da)，超(chao)過50%，主要用(yong)于電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)(dian)纜、變壓(ya)(ya)(ya)(ya)器、開關、連接件等。其中(zhong)電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)(dian)纜對銅(tong)(tong)的(de)(de)(de)(de)(de)(de)(de)(de)(de)需(xu)求(qiu)量占電(dian)(dian)(dian)(dian)(dian)(dian)力工業(ye)的(de)(de)(de)(de)(de)(de)(de)(de)(de)90%以(yi)上(shang)。因(yin)此，電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)(dian)纜行(xing)業(ye)的(de)(de)(de)(de)(de)(de)(de)(de)(de)發(fa)(fa)展無疑也將影(ying)響到銅(tong)(tong)的(de)(de)(de)(de)(de)(de)(de)(de)(de)需(xu)求(qiu)量和(he)價(jia)格(ge)(ge)。國(guo)(guo)家電(dian)(dian)(dian)(dian)(dian)(dian)網(wang)在(zai)2014年(nian)5月首(shou)次提出中(zhong)國(guo)(guo)經濟新常態，目前(qian)政(zheng)策有利于特(te)高(gao)(gao)壓(ya)(ya)(ya)(ya)建(jian)設(she)，國(guo)(guo)家電(dian)(dian)(dian)(dian)(dian)(dian)網(wang)2015年(nian)規劃的(de)(de)(de)(de)(de)(de)(de)(de)(de)13條線(xian)(xian)路預計(ji)能夠拉動超(chao)過3000億元(yuan)的(de)(de)(de)(de)(de)(de)(de)(de)(de)投資，另(ling)外國(guo)(guo)家電(dian)(dian)(dian)(dian)(dian)(dian)網(wang)也借(jie)助"一(yi)帶一(yi)路"推動特(te)高(gao)(gao)壓(ya)(ya)(ya)(ya)建(jian)設(she)，因(yin)此未(wei)來(lai)(lai)五年(nian)會是特(te)高(gao)(gao)壓(ya)(ya)(ya)(ya)行(xing)業(ye)的(de)(de)(de)(de)(de)(de)(de)(de)(de)黃金發(fa)(fa)展周期，電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)(dian)纜企業(ye)也將獲益豐厚。近日，國(guo)(guo)外知名(ming)研究(jiu)網(wang)站報道，未(wei)來(lai)(lai)5年(nian)，中(zhong)國(guo)(guo)將進(jin)入超(chao)高(gao)(gao)壓(ya)(ya)(ya)(ya)發(fa)(fa)展的(de)(de)(de)(de)(de)(de)(de)(de)(de)黃金時(shi)代(dai)，這使(shi)中(zhong)國(guo)(guo)的(de)(de)(de)(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)(dian)纜市場以(yi)8-9%的(de)(de)(de)(de)(de)(de)(de)(de)(de)年(nian)增率發(fa)(fa)展。

目前，南方軟電纜線電(dian)網正加(jia)快推進特(te)(te)高(gao)(gao)壓(ya)(ya)等(deng)新(xin)型基(ji)礎(chu)設施項目建設。在南方電(dian)網重(zhong)點(dian)特(te)(te)高(gao)(gao)壓(ya)(ya)工程(cheng)(cheng)——昆柳龍直(zhi)(zhi)流(liu)(liu)輸電(dian)工程(cheng)(cheng)建設方面，南網科(ke)研院科(ke)研工作者已連續攻克(ke)了特(te)(te)高(gao)(gao)電(dian)壓(ya)(ya)、特(te)(te)大(da)電(dian)流(liu)(liu)下的(de)絕緣特(te)(te)性、電(dian)磁環境、設備研制、試驗(yan)技(ji)術等(deng)世(shi)界級難題。有(you)力推動了這(zhe)個世(shi)界首(shou)個特(te)(te)高(gao)(gao)壓(ya)(ya)多端(duan)混合直(zhi)(zhi)流(liu)(liu)工程(cheng)(cheng)、國家特(te)(te)高(gao)(gao)壓(ya)(ya)多端(duan)直(zhi)(zhi)流(liu)(liu)示范工程(cheng)(cheng)的(de)建設進度。

軟電纜線光(guang)伏(fu)新政已出臺(tai)近兩個月(yue)，很(hen)多企業紛紛選擇開拓海(hai)外(wai)(wai)(wai)(wai)市(shi)場(chang)，至2020年累計市(shi)場(chang)容量(liang)將(jiang)(jiang)達5900億(yi)(yi)美元，其中約4000億(yi)(yi)美元將(jiang)(jiang)來自于(yu)項(xiang)目融資，海(hai)外(wai)(wai)(wai)(wai)市(shi)場(chang)復合增長率高達16%。但(dan)海(hai)外(wai)(wai)(wai)(wai)“風(feng)(feng)景”雖好，投資卻有風(feng)(feng)險(xian)(xian)，海(hai)外(wai)(wai)(wai)(wai)出行需謹慎。風(feng)(feng)險(xian)(xian)是既存的事實，遇(yu)到風(feng)(feng)險(xian)(xian)也(ye)不(bu)能停(ting)滯不(bu)前，所以對于(yu)海(hai)外(wai)(wai)(wai)(wai)市(shi)場(chang)風(feng)(feng)險(xian)(xian)把控是重要手段。

專業生產軟電纜線電(dian)線(xian)(xian)(xian)(xian)使(shi)(shi)用(yong)(yong)期(qi)限的(de)(de)長(chang)短(duan)，取決于電(dian)線(xian)(xian)(xian)(xian)的(de)(de)質(zhi)量和電(dian)線(xian)(xian)(xian)(xian)安裝的(de)(de)環境(jing)、使(shi)(shi)用(yong)(yong)環境(jing)。電(dian)線(xian)(xian)(xian)(xian)主要靠外面一(yi)層(ceng)包(bao)皮(pi)絕(jue)(jue)緣(yuan)，時(shi)(shi)(shi)間一(yi)長(chang)，受到(dao)腐(fu)蝕性(xing)氣體的(de)(de)腐(fu)蝕，絕(jue)(jue)緣(yuan)性(xing)能(neng)逐(zhu)漸降低，慢慢老化變(bian)硬(ying)，發脆或(huo)脫落，這時(shi)(shi)(shi)就不起絕(jue)(jue)緣(yuan)作用(yong)(yong)了。家(jia)用(yong)(yong)電(dian)線(xian)(xian)(xian)(xian)的(de)(de)外表(biao)的(de)(de)絕(jue)(jue)緣(yuan)層(ceng)多用(yong)(yong)塑料和橡膠制成(cheng)，使(shi)(shi)用(yong)(yong)時(shi)(shi)(shi)間長(chang)了就會老化，失(shi)去絕(jue)(jue)緣(yuan)作用(yong)(yong)。電(dian)線(xian)(xian)(xian)(xian)失(shi)去絕(jue)(jue)緣(yuan)的(de)(de)性(xing)能(neng)是很(hen)危險的(de)(de)，如果(guo)兩根電(dian)線(xian)(xian)(xian)(xian)碰在一(yi)起或(huo)火(huo)線(xian)(xian)(xian)(xian)碰到(dao)與大地(di)相接的(de)(de)東西，就會發生跑電(dian)現(xian)象，使(shi)(shi)局部(bu)電(dian)線(xian)(xian)(xian)(xian)的(de)(de)溫度升高，產生火(huo)花。如果(guo)電(dian)線(xian)(xian)(xian)(xian)附近有易燃物(wu)就容易引起著(zhu)火(huo)，造成(cheng)火(huo)災。
