6月15日，國家“皖電(dian)東送”重(zhong)點工(gong)程之一的500千伏(fu)馬錫雙線成功投運。至(zhi)此，從安徽500千伏(fu)馬鞍山開關站輸出的“皖電(dian)”通過該(gai)線經江蘇無錫500千伏(fu)惠泉、梅里和(he)蘇州車坊變電(dian)站送至(zhi)上(shang)海電(dian)網的通道(dao)全線貫通，華東電(dian)網又添“皖電(dian)東送”通途，其(qi)最大(da)輸送容量達400萬千伏(fu)安。
500千伏馬(ma)錫線工(gong)(gong)程(cheng)始于(yu)安(an)徽500千伏馬(ma)鞍(an)山開關(guan)站，終于(yu)無錫500千伏惠泉變(bian)電(dian)(dian)(dian)(dian)(dian)站，途(tu)經安(an)徽、江蘇(su)兩省(sheng)，線路全(quan)長169千米，全(quan)線同(tong)塔雙回路建(jian)(jian)(jian)設，共(gong)計鐵(tie)塔423基(ji)。該工(gong)(gong)程(cheng)是國家“皖(wan)電(dian)(dian)(dian)(dian)(dian)東送(song)”的重點項目之一，是滿足安(an)徽電(dian)(dian)(dian)(dian)(dian)力外送(song)、配合(he)淮南建(jian)(jian)(jian)設上海(hai)電(dian)(dian)(dian)(dian)(dian)力供應(ying)基(ji)地的重要輸(shu)電(dian)(dian)(dian)(dian)(dian)通道，同(tong)時也(ye)是提高蘇(su)南及上海(hai)電(dian)(dian)(dian)(dian)(dian)網輸(shu)電(dian)(dian)(dian)(dian)(dian)能力的長三(san)角主電(dian)(dian)(dian)(dian)(dian)網加強工(gong)(gong)程(cheng)。該工(gong)(gong)程(cheng)于(yu)2007年10月26日正式開工(gong)(gong)建(jian)(jian)(jian)設，2008年6月12日全(quan)線竣工(gong)(gong)，13日通過(guo)了竣工(gong)(gong)預驗(yan)收。該工(gong)(gong)程(cheng)的建(jian)(jian)(jian)成投運，為今年華東電(dian)(dian)(dian)(dian)(dian)網迎峰度夏(xia)新增了一條重要的輸(shu)電(dian)(dian)(dian)(dian)(dian)“大動脈”，將(jiang)在緩(huan)解(jie)無錫今年迎峰度夏(xia)電(dian)(dian)(dian)(dian)(dian)力緊張狀況中發揮重要作用。
