目前，南方鋁芯線電(dian)網正(zheng)加快推進特(te)(te)(te)高(gao)壓(ya)等(deng)新型基礎設(she)(she)(she)施項目建設(she)(she)(she)。在南方電(dian)網重(zhong)點特(te)(te)(te)高(gao)壓(ya)工(gong)程——昆柳龍直(zhi)(zhi)流(liu)輸(shu)電(dian)工(gong)程建設(she)(she)(she)方面，南網科研院科研工(gong)作(zuo)者已連(lian)續攻克了(le)特(te)(te)(te)高(gao)電(dian)壓(ya)、特(te)(te)(te)大電(dian)流(liu)下的(de)絕緣(yuan)特(te)(te)(te)性、電(dian)磁環境、設(she)(she)(she)備研制(zhi)、試驗技術等(deng)世(shi)界級(ji)難題。有力推動了(le)這(zhe)個世(shi)界首(shou)個特(te)(te)(te)高(gao)壓(ya)多(duo)(duo)端混合直(zhi)(zhi)流(liu)工(gong)程、國家特(te)(te)(te)高(gao)壓(ya)多(duo)(duo)端直(zhi)(zhi)流(liu)示范(fan)工(gong)程的(de)建設(she)(she)(she)進度。

專業生產鋁芯線報價數字萬(wan)用(yong)表(biao)法：首先(xian)把具有(you)斷點的(de)(de)電(dian)(dian)纜的(de)(de)一(yi)端(duan)接在220V火線，另(ling)一(yi)端(duan)使之懸空。調動萬(wan)用(yong)表(biao)的(de)(de)檔位(wei)使之打(da)到(dao)交(jiao)流2V電(dian)(dian)壓擋。然后從故障電(dian)(dian)纜的(de)(de)火線接入端(duan)開始，一(yi)只手(shou)緊(jin)握黑表(biao)筆(bi)(bi)(bi)，紅(hong)表(biao)筆(bi)(bi)(bi)沿著故障電(dian)(dian)纜的(de)(de)絕緣(yuan)層緩慢滑動。電(dian)(dian)纜無斷點處的(de)(de)電(dian)(dian)壓值大(da)約為0.445V左右。當紅(hong)表(biao)筆(bi)(bi)(bi)移動到(dao)某處時，萬(wan)用(yong)表(biao)顯示的(de)(de)電(dian)(dian)壓值驟(zou)降為正常電(dian)(dian)壓的(de)(de)1/10即(ji)0.04V時。此時基(ji)本可(ke)以斷定斷點處在該(gai)位(wei)置向(xiang)前（火線接入端(duan)）15cm處。

印度總理莫迪當地時間3日就新冠肺炎疫情發表全國電視講話，呼吁民眾在4月5日晚上9點熄燈9分鐘，以“燭光”祈福團結抗疫。然而，該建議隨后在該國引發巨大爭議，馬哈拉施特拉邦能源部長尼廷·勞特就警告說，這一措施可能導致鋁芯線電網(wang)崩潰，意味(wei)著(zhu)應急服務也(ye)將受(shou)到影響。對(dui)此，據《印度斯坦時(shi)報》報道，印度電力部澄清：總(zong)理的熄燈呼(hu)吁只針對(dui)普通住宅，不會影響電網(wang)系統(tong)。

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，鋁芯線報價電(dian)(dian)(dian)(dian)(dian)(dian)力(li)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)占(zhan)據電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)業務的(de)(de)最大部分，規模占(zhan)比(bi)35.7%，其(qi)次(ci)是電(dian)(dian)(dian)(dian)(dian)(dian)氣裝備(bei)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)、繞組線(xian)(xian)，分別占(zhan)比(bi)20%和15.7%。近年(nian)來，我國電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)行(xing)(xing)業保持了較快發展(zhan)(zhan)勢(shi)頭，作為國民(min)經濟的(de)(de)最重(zhong)要的(de)(de)支(zhi)撐產業之一(yi)，電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)行(xing)(xing)業在中(zhong)國有(you)著廣闊的(de)(de)市場。根(gen)據近幾年(nian)的(de)(de)情(qing)況來看，我國電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)行(xing)(xing)業銷(xiao)售(shou)收入總體呈現(xian)上(shang)升趨勢(shi)，其(qi)中(zhong)2016年(nian)銷(xiao)售(shou)收入創新高(gao)達13924億元(yuan)，2017年(nian)電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)銷(xiao)售(shou)收入出現(xian)小幅下降(jiang)，為13513億元(yuan)。隨(sui)著我國對基礎(chu)設施投入的(de)(de)加(jia)大，以及(ji)新能源、軍工(gong)、海洋工(gong)程、軌道交通(tong)、特(te)高(gao)壓、智能電(dian)(dian)(dian)(dian)(dian)(dian)網(wang)的(de)(de)發展(zhan)(zhan)得到(dao)進(jin)(jin)一(yi)步貫徹落實，市場對電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)的(de)(de)需求在不斷增強，尤其(qi)是在高(gao)端裝備(bei)用電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)方面，未來我國電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)行(xing)(xing)業銷(xiao)售(shou)收入仍將進(jin)(jin)一(yi)步增加(jia)。
