12月9日，中(zhong)國中(zhong)鐵四(si)局(ju)電(dian)(dian)氣化公合寧(ning)四(si)電(dian)(dian)項(xiang)目經理部(bu)施工(gong)合寧(ning)客(ke)運(yun)專線(xian)(xian)馬廠配電(dian)(dian)所到合肥三十里埠站(zhan)之間長達80公里的長干電(dian)(dian)纜線(xian)(xian)路一次性送電(dian)(dian)成功(gong)。
合(he)寧高速(su)鐵(tie)路是(shi)我國(guo)第(di)一(yi)條(tiao)高速(su)鐵(tie)路客(ke)運(yun)專(zhuan)線，客(ke)車設計時(shi)速(su)為250公(gong)里，在電(dian)(dian)(dian)氣化方面(mian)使用了很(hen)多國(guo)內(nei)尖端技術，特別是(shi)10千伏第(di)一(yi)電(dian)(dian)(dian)力貫(guan)通線，從馬廠(chang)配(pei)電(dian)(dian)(dian)所到(dao)合(he)肥(fei)三(san)十里埠站在我國(guo)第(di)一(yi)次(ci)全程采(cai)用1×50單蕊(rui)高壓電(dian)(dian)(dian)力電(dian)(dian)(dian)纜。長(chang)干電(dian)(dian)(dian)纜線路的容(rong)性量非常(chang)大，空載送(song)電(dian)(dian)(dian)在電(dian)(dian)(dian)力專(zhuan)業中是(shi)一(yi)項非常(chang)困(kun)難的技術課(ke)題。中鐵(tie)四局(ju)電(dian)(dian)(dian)氣化公(gong)司克(ke)服重(zhong)重(zhong)困(kun)難，實現了從馬廠(chang)配(pei)電(dian)(dian)(dian)所到(dao)合(he)肥(fei)三(san)十里埠站鋪設電(dian)(dian)(dian)纜全長(chang)80公(gong)里的一(yi)次(ci)送(song)電(dian)(dian)(dian)成(cheng)(cheng)功(gong)，并在72小時(shi)后運(yun)行正常(chang)，成(cheng)(cheng)為國(guo)內(nei)首次(ci)長(chang)干電(dian)(dian)(dian)纜線路一(yi)次(ci)性送(song)電(dian)(dian)(dian)成(cheng)(cheng)功(gong)。
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。
