5月10日，在(zai)安(an)(an)徽省明光(guang)市橋頭鎮境(jing)(jing)內，在(zai)牽(qian)張設備的轟鳴(ming)聲中，八根銀色(se)鋼芯鋁(lv)導線(xian)在(zai)牽(qian)引繩拖(tuo)動下(xia)緩緩升起，標(biao)志(zhi)著(zhu)由(you)安(an)(an)徽送(song)變電(dian)工(gong)程公司承建的淮南—南京—上海(hai)1000千伏(fu)交流特高壓(ya)輸電(dian)線(xian)路工(gong)程3標(biao)段，在(zai)安(an)(an)徽境(jing)(jing)內的3個標(biao)段中率先轉(zhuan)入架線(xian)施(shi)工(gong)階段，由(you)此(ci)，該工(gong)程安(an)(an)徽段線(xian)路拉開正式架線(xian)施(shi)工(gong)的序幕。
3標段(duan)線路(lu)全部(bu)位于(yu)安徽省明光市境內，全長(chang)約52千米(mi)，按同(tong)塔(ta)雙回路(lu)架設(she)，新(xin)建鐵(tie)塔(ta)101基，計劃2015年底完工(gong)(gong)(gong)(gong)并具(ju)備送電條件。此次架線施(shi)(shi)工(gong)(gong)(gong)(gong)共分為七個架線區段(duan)，送變電公(gong)司將先后(hou)投(tou)入6支施(shi)(shi)工(gong)(gong)(gong)(gong)隊伍近300人(ren)，確保(bao)工(gong)(gong)(gong)(gong)程架線施(shi)(shi)工(gong)(gong)(gong)(gong)穩步推進(jin)。
該工(gong)(gong)(gong)程(cheng)(cheng)是我國(guo)第四個特(te)(te)高壓交流(liu)工(gong)(gong)(gong)程(cheng)(cheng)，迄今(jin)為止規模最(zui)(zui)大、投資(zi)最(zui)(zui)大、難度(du)最(zui)(zui)大，也是國(guo)家確定的大氣(qi)污染防治行動計劃12個重點輸(shu)電(dian)(dian)(dian)通道中(zhong)首個獲得核準的特(te)(te)高壓工(gong)(gong)(gong)程(cheng)(cheng)。工(gong)(gong)(gong)程(cheng)(cheng)包(bao)括新建南京、泰(tai)州、蘇州三(san)座變電(dian)(dian)(dian)站，擴建淮南、滬西兩座變電(dian)(dian)(dian)站，變電(dian)(dian)(dian)容量1200萬(wan)千(qian)伏安，新建輸(shu)電(dian)(dian)(dian)線路2×779.5千(qian)米，工(gong)(gong)(gong)程(cheng)(cheng)核準靜態投資(zi)261.1億元。線路途經安徽、江蘇、上(shang)海(hai)兩省(sheng)一市的22個縣(xian)市，其(qi)中(zhong)安徽境內線路近160公里(li)，新建鐵塔309基。工(gong)(gong)(gong)程(cheng)(cheng)建成后，將形成首個特(te)(te)高壓交流(liu)雙環網(wang)，對于提(ti)高華(hua)東電(dian)(dian)(dian)網(wang)內部電(dian)(dian)(dian)力(li)(li)交換能力(li)(li)和接納區(qu)外(wai)來電(dian)(dian)(dian)能力(li)(li)，有效緩解(jie)長三(san)角地區(qu)短路電(dian)(dian)(dian)流(liu)大面積(ji)超標問(wen)題(ti)，提(ti)升(sheng)電(dian)(dian)(dian)網(wang)安全穩定水平，增強華(hua)東電(dian)(dian)(dian)網(wang)抵御重大事故(gu)能力(li)(li)，滿足經濟(ji)社會發展等具有十分重要的意義。
