6月15日，國(guo)家“皖(wan)(wan)電(dian)東(dong)送”重(zhong)點(dian)工程之一的(de)500千(qian)伏馬(ma)錫雙線(xian)成功投運。至(zhi)此，從安(an)(an)徽500千(qian)伏馬(ma)鞍山開關(guan)站(zhan)輸出的(de)“皖(wan)(wan)電(dian)”通(tong)過該線(xian)經江蘇(su)無錫500千(qian)伏惠泉、梅(mei)里和(he)蘇(su)州車坊變電(dian)站(zhan)送至(zhi)上(shang)海電(dian)網(wang)的(de)通(tong)道全線(xian)貫通(tong)，華東(dong)電(dian)網(wang)又添“皖(wan)(wan)電(dian)東(dong)送”通(tong)途，其最大(da)輸送容(rong)量達400萬千(qian)伏安(an)(an)。
500千伏馬錫(xi)(xi)線(xian)工(gong)(gong)(gong)程(cheng)(cheng)始(shi)于安徽500千伏馬鞍(an)山開(kai)關(guan)站，終于無(wu)錫(xi)(xi)500千伏惠泉(quan)變電(dian)(dian)(dian)站，途經安徽、江蘇兩省，線(xian)路(lu)全長169千米，全線(xian)同塔(ta)雙(shuang)回路(lu)建(jian)(jian)設(she)，共(gong)計鐵塔(ta)423基。該工(gong)(gong)(gong)程(cheng)(cheng)是(shi)國家“皖電(dian)(dian)(dian)東送”的(de)重(zhong)點項目(mu)之一，是(shi)滿足安徽電(dian)(dian)(dian)力(li)外送、配合淮南(nan)建(jian)(jian)設(she)上海電(dian)(dian)(dian)力(li)供應基地的(de)重(zhong)要輸電(dian)(dian)(dian)通道，同時(shi)也是(shi)提高(gao)蘇南(nan)及上海電(dian)(dian)(dian)網(wang)輸電(dian)(dian)(dian)能力(li)的(de)長三角主電(dian)(dian)(dian)網(wang)加強工(gong)(gong)(gong)程(cheng)(cheng)。該工(gong)(gong)(gong)程(cheng)(cheng)于2007年10月(yue)26日正式(shi)開(kai)工(gong)(gong)(gong)建(jian)(jian)設(she)，2008年6月(yue)12日全線(xian)竣工(gong)(gong)(gong)，13日通過了(le)竣工(gong)(gong)(gong)預驗收(shou)。該工(gong)(gong)(gong)程(cheng)(cheng)的(de)建(jian)(jian)成投運，為今(jin)年華東電(dian)(dian)(dian)網(wang)迎峰度夏新增了(le)一條重(zhong)要的(de)輸電(dian)(dian)(dian)“大動(dong)脈”，將(jiang)在緩解無(wu)錫(xi)(xi)今(jin)年迎峰度夏電(dian)(dian)(dian)力(li)緊張狀況中發揮重(zhong)要作用(yong)。
