12月9日，中國中鐵(tie)四局電(dian)氣化公(gong)合寧四電(dian)項目經理部施工合寧客(ke)運專線馬廠配電(dian)所到合肥(fei)三十里埠站之間長(chang)達80公(gong)里的長(chang)干電(dian)纜線路一次性送電(dian)成功。
合寧高速(su)鐵(tie)路是我國(guo)(guo)第(di)一(yi)(yi)(yi)條高速(su)鐵(tie)路客(ke)運(yun)專(zhuan)線，客(ke)車設計時速(su)為(wei)250公(gong)里，在(zai)電(dian)(dian)(dian)氣化方面使用了很多國(guo)(guo)內尖端技(ji)術，特(te)別是10千伏(fu)第(di)一(yi)(yi)(yi)電(dian)(dian)(dian)力貫(guan)通線，從馬廠(chang)配(pei)電(dian)(dian)(dian)所到合肥三(san)(san)十(shi)里埠(bu)站(zhan)在(zai)我國(guo)(guo)第(di)一(yi)(yi)(yi)次(ci)(ci)全程采用1×50單蕊(rui)高壓電(dian)(dian)(dian)力電(dian)(dian)(dian)纜(lan)(lan)(lan)。長干電(dian)(dian)(dian)纜(lan)(lan)(lan)線路的容性量非常(chang)大，空載送(song)電(dian)(dian)(dian)在(zai)電(dian)(dian)(dian)力專(zhuan)業中是一(yi)(yi)(yi)項非常(chang)困難(nan)的技(ji)術課題(ti)。中鐵(tie)四局電(dian)(dian)(dian)氣化公(gong)司(si)克服重(zhong)重(zhong)困難(nan)，實現了從馬廠(chang)配(pei)電(dian)(dian)(dian)所到合肥三(san)(san)十(shi)里埠(bu)站(zhan)鋪設電(dian)(dian)(dian)纜(lan)(lan)(lan)全長80公(gong)里的一(yi)(yi)(yi)次(ci)(ci)送(song)電(dian)(dian)(dian)成(cheng)(cheng)功，并在(zai)72小時后運(yun)行正(zheng)常(chang)，成(cheng)(cheng)為(wei)國(guo)(guo)內首次(ci)(ci)長干電(dian)(dian)(dian)纜(lan)(lan)(lan)線路一(yi)(yi)(yi)次(ci)(ci)性送(song)電(dian)(dian)(dian)成(cheng)(cheng)功。
長干電纜線路一次性成功送電標志著中鐵四局電氣化公司已經掌握了長干電纜空載投運的技術課題和施工工藝技術，為我國以后在長干電纜空載投運這一技術運用上提供了范本，積累了寶貴的經驗。
