5月28日，青島地鐵8號線“雙接頭”分線箱順利完成送電，為地鐵1號線供電提供保障，也為8號線電流接入創造了條件。

地鐵8號(hao)線(xian)“雙接頭”分線(xian)箱是1號(hao)線(xian)勝利(li)(li)橋(qiao)站(zhan)(zhan)開(kai)(kai)閉所、8號(hao)線(xian)閆(yan)(yan)家(jia)山(shan)(shan)站(zhan)(zhan)開(kai)(kai)閉所供(gong)電(dian)(dian)(dian)共接工(gong)(gong)程，由(you)浩越（青島(dao)）建設(she)(she)電(dian)(dian)(dian)力工(gong)(gong)程有限公司具體實施，該工(gong)(gong)程屬于35千伏(fu)高壓施工(gong)(gong)項目,從國(guo)家(jia)電(dian)(dian)(dian)網虎山(shan)(shan)變電(dian)(dian)(dian)站(zhan)(zhan)引出(chu)一路(lu)(lu)高壓電(dian)(dian)(dian)源到(dao)分線(xian)箱，從分線(xian)箱輸(shu)出(chu)兩路(lu)(lu)電(dian)(dian)(dian)源。一路(lu)(lu)為地鐵1號(hao)線(xian)勝利(li)(li)橋(qiao)站(zhan)(zhan)開(kai)(kai)閉所及周邊(bian)7站(zhan)(zhan)8區(qu)(qu)間約(yue)11公里(li)的(de)范(fan)圍(wei)供(gong)電(dian)(dian)(dian)；一路(lu)(lu)為地鐵8號(hao)線(xian)閆(yan)(yan)家(jia)山(shan)(shan)站(zhan)(zhan)開(kai)(kai)閉所南昌路(lu)(lu)北站(zhan)(zhan)至紅島(dao)科技館站(zhan)(zhan)6站(zhan)(zhan)5區(qu)(qu)間約(yue)17公里(li)的(de)范(fan)圍(wei)供(gong)電(dian)(dian)(dian)。主(zhu)要工(gong)(gong)作(zuo)為新建分線(xian)箱1座、敷設(she)(she)高壓電(dian)(dian)(dian)纜(lan)約(yue)420米(mi)和(he)電(dian)(dian)(dian)纜(lan)設(she)(she)備的(de)試驗調試，以及外部相應的(de)配套工(gong)(gong)作(zuo)。

本工(gong)程采(cai)用的(de)電(dian)(dian)(dian)纜為(wei)目(mu)前青島地鐵最(zui)高(gao)(gao)規格的(de)單(dan)(dan)芯高(gao)(gao)電(dian)(dian)(dian)壓電(dian)(dian)(dian)纜，其直徑達(da)到7厘米(mi)，總重量達(da)6.5噸，需要(yao)將3根(gen)單(dan)(dan)芯電(dian)(dian)(dian)纜擺成“品”字形敷(fu)設至(zhi)2米(mi)高(gao)(gao)的(de)管(guan)廊支架(jia)上固定(ding)，受管(guan)廊空間限制（高(gao)(gao)2.2米(mi)，寬2米(mi)）無(wu)法使用機械，只(zhi)能靠有(you)限的(de)人力將沉重的(de)電(dian)(dian)(dian)纜抬(tai)放到支架(jia)上，且(qie)管(guan)廊支架(jia)上還有(you)已經通電(dian)(dian)(dian)的(de)多條高(gao)(gao)壓電(dian)(dian)(dian)纜，施工(gong)危險系(xi)數高(gao)(gao)，難度大。

“起跑即沖刺、開(kai)(kai)(kai)局即決戰”八號(hao)(hao)線公司迎難而上絕不(bu)退縮，為滿足1號(hao)(hao)線勝利(li)橋(qiao)開(kai)(kai)(kai)站閉所(suo)5月(yue)底外部電(dian)(dian)源引入的工(gong)(gong)期需求(qiu)，從3月(yue)份開(kai)(kai)(kai)始著手(shou)準(zhun)備，僅在短短3個月(yue)時(shi)間(jian)內(nei)(nei)就完(wan)(wan)(wan)成了(le)方案研究(jiu)、圖紙設計、規(gui)劃及綠遷手(shou)續辦(ban)理、洽商(shang)進場(chang)、設備采(cai)購供貨、電(dian)(dian)力設備安裝調試、施工(gong)(gong)驗收、送電(dian)(dian)等全部工(gong)(gong)作。該(gai)項(xiang)目位于綠化帶內(nei)(nei)，地理位置特(te)殊，只能(neng)在有(you)限的范(fan)圍內(nei)(nei)進行施工(gong)(gong)，且需要辦(ban)理綠遷、占掘路，施工(gong)(gong)過程(cheng)困難大，手(shou)續程(cheng)序(xu)繁(fan)多，但為了(le)保證(zheng)按時(shi)完(wan)(wan)(wan)成送電(dian)(dian)，八號(hao)(hao)線公司提(ti)前謀劃、精心組(zu)織(zhi)、嚴格(ge)管理，在青島市各相關(guan)部門、地鐵集(ji)團(tuan)、供電(dian)(dian)公司的大力支持與幫(bang)助下，最終高(gao)質量(liang)高(gao)標準(zhun)的提(ti)前完(wan)(wan)(wan)成了(le)各項(xiang)工(gong)(gong)作并順利(li)完(wan)(wan)(wan)成送電(dian)(dian)任(ren)務(wu)。

青島(dao)地鐵(tie)8號線(xian)分(fen)線(xian)箱新(xin)建(jian)工程順利(li)送(song)電是8號線(xian)建(jian)設過(guo)程中(zhong)的(de)一個重大節點(dian)。展現了(le)(le)地鐵(tie)建(jian)設者(zhe)攻堅克難的(de)精神，不僅(jin)為1號線(xian)供電提供了(le)(le)保障，同時也為地鐵(tie)8號線(xian)后續(xu)供電接入奠(dian)定(ding)了(le)(le)堅實的(de)基礎，為建(jian)設開放、現代、活力、時尚的(de)青島(dao)再添(tian)“新(xin)動能”。
