12月9日，中國(guo)中鐵四局電(dian)氣化公合寧四電(dian)項目經理部(bu)施工合寧客運專線馬廠配電(dian)所到(dao)合肥三十里(li)埠站之間長(chang)達80公里(li)的長(chang)干電(dian)纜線路一次性(xing)送電(dian)成功。
合寧高(gao)速鐵路是(shi)我(wo)國第(di)(di)一條高(gao)速鐵路客(ke)運專線，客(ke)車設(she)計時速為250公里，在電(dian)(dian)(dian)(dian)(dian)(dian)氣(qi)化方面使用(yong)了很多國內(nei)尖端技術，特(te)別(bie)是(shi)10千伏第(di)(di)一電(dian)(dian)(dian)(dian)(dian)(dian)力貫(guan)通線，從馬廠配電(dian)(dian)(dian)(dian)(dian)(dian)所到合肥(fei)三(san)十(shi)里埠站在我(wo)國第(di)(di)一次(ci)全程采用(yong)1×50單(dan)蕊高(gao)壓電(dian)(dian)(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)(dian)(dian)纜。長(chang)(chang)干電(dian)(dian)(dian)(dian)(dian)(dian)纜線路的容性量非(fei)常大，空載送電(dian)(dian)(dian)(dian)(dian)(dian)在電(dian)(dian)(dian)(dian)(dian)(dian)力專業中是(shi)一項(xiang)非(fei)常困(kun)難(nan)的技術課題。中鐵四(si)局電(dian)(dian)(dian)(dian)(dian)(dian)氣(qi)化公司克服重(zhong)重(zhong)困(kun)難(nan)，實現了從馬廠配電(dian)(dian)(dian)(dian)(dian)(dian)所到合肥(fei)三(san)十(shi)里埠站鋪設(she)電(dian)(dian)(dian)(dian)(dian)(dian)纜全長(chang)(chang)80公里的一次(ci)送電(dian)(dian)(dian)(dian)(dian)(dian)成功(gong)(gong)，并在72小(xiao)時后運行正(zheng)常，成為國內(nei)首次(ci)長(chang)(chang)干電(dian)(dian)(dian)(dian)(dian)(dian)纜線路一次(ci)性送電(dian)(dian)(dian)(dian)(dian)(dian)成功(gong)(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。
