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(tie)(tie)8號(hao)線(xian)(xian)“雙接頭”分線(xian)(xian)箱是(shi)1號(hao)線(xian)(xian)勝利橋(qiao)站(zhan)(zhan)(zhan)開閉(bi)所(suo)(suo)、8號(hao)線(xian)(xian)閆家(jia)山(shan)站(zhan)(zhan)(zhan)開閉(bi)所(suo)(suo)供(gong)(gong)電(dian)(dian)(dian)(dian)共接工(gong)程，由浩越(yue)（青島）建設(she)(she)電(dian)(dian)(dian)(dian)力工(gong)程有限公(gong)司具體實施，該工(gong)程屬于35千(qian)伏高壓(ya)(ya)施工(gong)項目(mu),從國家(jia)電(dian)(dian)(dian)(dian)網虎山(shan)變電(dian)(dian)(dian)(dian)站(zhan)(zhan)(zhan)引出一(yi)路(lu)高壓(ya)(ya)電(dian)(dian)(dian)(dian)源到分線(xian)(xian)箱，從分線(xian)(xian)箱輸出兩路(lu)電(dian)(dian)(dian)(dian)源。一(yi)路(lu)為地鐵(tie)(tie)1號(hao)線(xian)(xian)勝利橋(qiao)站(zhan)(zhan)(zhan)開閉(bi)所(suo)(suo)及(ji)周邊7站(zhan)(zhan)(zhan)8區間(jian)約(yue)(yue)11公(gong)里(li)的(de)范(fan)圍(wei)供(gong)(gong)電(dian)(dian)(dian)(dian)；一(yi)路(lu)為地鐵(tie)(tie)8號(hao)線(xian)(xian)閆家(jia)山(shan)站(zhan)(zhan)(zhan)開閉(bi)所(suo)(suo)南昌路(lu)北站(zhan)(zhan)(zhan)至紅島科(ke)技(ji)館站(zhan)(zhan)(zhan)6站(zhan)(zhan)(zhan)5區間(jian)約(yue)(yue)17公(gong)里(li)的(de)范(fan)圍(wei)供(gong)(gong)電(dian)(dian)(dian)(dian)。主(zhu)要工(gong)作為新建分線(xian)(xian)箱1座(zuo)、敷設(she)(she)高壓(ya)(ya)電(dian)(dian)(dian)(dian)纜約(yue)(yue)420米(mi)和電(dian)(dian)(dian)(dian)纜設(she)(she)備的(de)試驗調試，以及(ji)外(wai)部相應的(de)配套工(gong)作。

本工程采用(yong)的電(dian)纜(lan)為(wei)目前青(qing)島地鐵(tie)最(zui)高(gao)(gao)(gao)規格的單(dan)芯高(gao)(gao)(gao)電(dian)壓電(dian)纜(lan)，其直徑達到7厘米(mi)，總(zong)重(zhong)量(liang)達6.5噸，需要將(jiang)3根單(dan)芯電(dian)纜(lan)擺成“品”字形(xing)敷設(she)至2米(mi)高(gao)(gao)(gao)的管廊(lang)支(zhi)架(jia)上固定，受管廊(lang)空間限(xian)制(zhi)（高(gao)(gao)(gao)2.2米(mi)，寬2米(mi)）無法使(shi)用(yong)機械，只能靠有限(xian)的人力(li)將(jiang)沉重(zhong)的電(dian)纜(lan)抬放到支(zhi)架(jia)上，且(qie)管廊(lang)支(zhi)架(jia)上還有已經通電(dian)的多(duo)條(tiao)高(gao)(gao)(gao)壓電(dian)纜(lan)，施工危險系數高(gao)(gao)(gao)，難度大。

“起跑即(ji)(ji)沖(chong)刺、開局即(ji)(ji)決戰(zhan)”八號線(xian)公(gong)司(si)迎難而上絕不(bu)退縮，為滿足1號線(xian)勝利(li)橋(qiao)開站閉所5月(yue)(yue)底外部電(dian)源引(yin)入的工(gong)(gong)(gong)期需(xu)求，從3月(yue)(yue)份開始著手準備，僅在(zai)短(duan)短(duan)3個(ge)月(yue)(yue)時間(jian)內就完成(cheng)了方案研究(jiu)、圖(tu)紙(zhi)設計、規劃(hua)及綠(lv)遷(qian)手續(xu)辦理、洽(qia)商進場(chang)、設備采購供貨、電(dian)力設備安裝調試(shi)、施(shi)工(gong)(gong)(gong)驗收、送電(dian)等全部工(gong)(gong)(gong)作(zuo)(zuo)。該(gai)項目位于綠(lv)化帶內，地理位置特殊，只能(neng)在(zai)有限的范圍內進行施(shi)工(gong)(gong)(gong)，且(qie)需(xu)要辦理綠(lv)遷(qian)、占掘(jue)路(lu)，施(shi)工(gong)(gong)(gong)過(guo)程困難大，手續(xu)程序繁多，但為了保證按時完成(cheng)送電(dian)，八號線(xian)公(gong)司(si)提(ti)前謀劃(hua)、精(jing)心組織、嚴格管(guan)理，在(zai)青島(dao)市(shi)各(ge)相關部門(men)、地鐵(tie)集(ji)團、供電(dian)公(gong)司(si)的大力支(zhi)持與幫助下，最終(zhong)高質量高標準的提(ti)前完成(cheng)了各(ge)項工(gong)(gong)(gong)作(zuo)(zuo)并順利(li)完成(cheng)送電(dian)任(ren)務。

青島(dao)地鐵(tie)8號線(xian)分線(xian)箱新建工程(cheng)順利送(song)電是8號線(xian)建設過程(cheng)中的(de)一個(ge)重大節(jie)點。展現了(le)地鐵(tie)建設者攻(gong)堅克難的(de)精(jing)神，不(bu)僅為1號線(xian)供(gong)電提(ti)供(gong)了(le)保障，同時(shi)也為地鐵(tie)8號線(xian)后(hou)續供(gong)電接入(ru)奠定了(le)堅實的(de)基(ji)礎(chu)，為建設開放(fang)、現代、活力(li)、時(shi)尚的(de)青島(dao)再添(tian)“新動能(neng)”。
