6月30日，南(nan)(nan)方電(dian)(dian)網(wang)重(zhong)(zhong)點(dian)工(gong)(gong)程(cheng)——云(yun)南(nan)(nan)硯山至廣西(xi)靖西(xi)第(di)二(er)回(hui)500千(qian)(qian)伏交(jiao)流(liu)輸電(dian)(dian)工(gong)(gong)程(cheng)（簡稱滇南(nan)(nan)二(er)回(hui)送(song)出(chu)工(gong)(gong)程(cheng)）建成投運(yun)。該工(gong)(gong)程(cheng)是南(nan)(nan)方電(dian)(dian)網(wang)西(xi)電(dian)(dian)東送(song)500千(qian)(qian)伏主網(wang)架的重(zhong)(zhong)要組(zu)成部(bu)分(fen)，建成后云(yun)南(nan)(nan)500千(qian)(qian)伏交(jiao)流(liu)外(wai)送(song)線路增(zeng)至5回(hui)，可提高云(yun)南(nan)(nan)外(wai)送(song)輸電(dian)(dian)能力(li)約50萬千(qian)(qian)瓦，對(dui)保障(zhang)南(nan)(nan)方電(dian)(dian)網(wang)主網(wang)架安全穩定運(yun)行、云(yun)南(nan)(nan)汛(xun)期(qi)水電(dian)(dian)送(song)出(chu)、廣西(xi)電(dian)(dian)力(li)供(gong)應等(deng)具有(you)重(zhong)(zhong)要意義。
該工程(cheng)起于(yu)云南(nan)硯山(shan)變電站(zhan)，止于(yu)廣(guang)西靖(jing)(jing)西變電站(zhan)，途(tu)經云南(nan)硯山(shan)、廣(guang)南(nan)、富寧縣(xian)(xian)和廣(guang)西那坡、靖(jing)(jing)西縣(xian)(xian)，全長252.7公里。
工程(cheng)(cheng)建設(she)(she)過(guo)程(cheng)(cheng)中，南方(fang)電網公司還采用(yong)節能(neng)、降耗(hao)、節水、環保的先進技術(shu)設(she)(she)備(bei)和產品。與(yu)常規線(xian)路使用(yong)鐵(tie)塔相(xiang)比，該(gai)工程(cheng)(cheng)采用(yong)緊(jin)湊型(xing)鐵(tie)塔，減(jian)少(shao)塔材約10%左右(you)，塔基占地(di)面(mian)積(ji)(ji)(ji)也減(jian)少(shao)約20%；采用(yong)緊(jin)湊型(xing)線(xian)路建設(she)(she)方(fang)式，可節約線(xian)路走(zou)(zou)廊面(mian)積(ji)(ji)(ji)約3000到4000畝，共節約線(xian)路走(zou)(zou)廊林區(qu)與(yu)塔基占地(di)面(mian)積(ji)(ji)(ji)投資費用(yong)約2.5億元。
