5月10日，在(zai)安(an)(an)徽省明光市橋頭(tou)鎮境內，在(zai)牽(qian)張設備的(de)轟鳴(ming)聲中，八根銀色鋼(gang)芯鋁導(dao)線(xian)在(zai)牽(qian)引繩拖(tuo)動(dong)下(xia)緩(huan)(huan)緩(huan)(huan)升起，標(biao)志(zhi)著由(you)(you)安(an)(an)徽送變電(dian)工(gong)程(cheng)公司承建的(de)淮南—南京(jing)—上海(hai)1000千伏(fu)交(jiao)流特(te)高壓輸(shu)電(dian)線(xian)路工(gong)程(cheng)3標(biao)段(duan)(duan)，在(zai)安(an)(an)徽境內的(de)3個(ge)標(biao)段(duan)(duan)中率(lv)先轉(zhuan)入架(jia)線(xian)施(shi)工(gong)階段(duan)(duan)，由(you)(you)此(ci)，該工(gong)程(cheng)安(an)(an)徽段(duan)(duan)線(xian)路拉開正式架(jia)線(xian)施(shi)工(gong)的(de)序幕。
3標段(duan)線(xian)路全(quan)部位于(yu)安徽省明光市(shi)境(jing)內，全(quan)長(chang)約52千米，按同(tong)塔雙回(hui)路架設，新建鐵(tie)塔101基，計劃2015年(nian)底完(wan)工并(bing)具備送電(dian)(dian)條件。此次(ci)架線(xian)施工共(gong)分為(wei)七(qi)個架線(xian)區段(duan)，送變電(dian)(dian)公(gong)司將先后(hou)投入6支(zhi)施工隊(dui)伍(wu)近(jin)300人，確保工程架線(xian)施工穩步(bu)推進。
該工(gong)程(cheng)是(shi)我國(guo)(guo)第四個(ge)(ge)(ge)特高(gao)壓交(jiao)流工(gong)程(cheng)，迄今為止(zhi)規(gui)模最(zui)大(da)(da)、投資(zi)最(zui)大(da)(da)、難度最(zui)大(da)(da)，也是(shi)國(guo)(guo)家確定的(de)大(da)(da)氣污染防治行動計劃(hua)12個(ge)(ge)(ge)重(zhong)(zhong)點輸電(dian)(dian)(dian)(dian)通道中首個(ge)(ge)(ge)獲得(de)核準的(de)特高(gao)壓工(gong)程(cheng)。工(gong)程(cheng)包括新(xin)建南(nan)京(jing)、泰州(zhou)、蘇州(zhou)三座(zuo)變電(dian)(dian)(dian)(dian)站，擴建淮南(nan)、滬西兩座(zuo)變電(dian)(dian)(dian)(dian)站，變電(dian)(dian)(dian)(dian)容量1200萬千伏安(an)(an)，新(xin)建輸電(dian)(dian)(dian)(dian)線(xian)路2×779.5千米(mi)，工(gong)程(cheng)核準靜(jing)態投資(zi)261.1億元。線(xian)路途(tu)經安(an)(an)徽、江蘇、上(shang)海兩省(sheng)一(yi)市的(de)22個(ge)(ge)(ge)縣(xian)市，其中安(an)(an)徽境內線(xian)路近160公里，新(xin)建鐵塔309基。工(gong)程(cheng)建成后，將(jiang)形(xing)成首個(ge)(ge)(ge)特高(gao)壓交(jiao)流雙環網，對(dui)于(yu)提(ti)高(gao)華(hua)東電(dian)(dian)(dian)(dian)網內部(bu)電(dian)(dian)(dian)(dian)力交(jiao)換(huan)能力和接納區外來電(dian)(dian)(dian)(dian)能力，有效緩解長三角地(di)區短路電(dian)(dian)(dian)(dian)流大(da)(da)面(mian)積超(chao)標(biao)問題，提(ti)升電(dian)(dian)(dian)(dian)網安(an)(an)全(quan)穩(wen)定水平，增強華(hua)東電(dian)(dian)(dian)(dian)網抵(di)御重(zhong)(zhong)大(da)(da)事故能力，滿足經濟社會發(fa)展等具有十分重(zhong)(zhong)要的(de)意義。
