８０年代以前，高層(ceng)(ceng)(ceng)建筑中(zhong)(zhong)的(de)(de)(de)(de)供(gong)電(dian)(dian)(dian)主(zhu)干(gan)(gan)線(xian)(xian)主(zhu)要采用(yong)可靠性(xing)較好(hao)的(de)(de)(de)(de)普通電(dian)(dian)(dian)纜(lan)(lan)，電(dian)(dian)(dian)纜(lan)(lan)在(zai)電(dian)(dian)(dian)氣(qi)豎井內沿墻(qiang)壁(bi)用(yong)支架或電(dian)(dian)(dian)纜(lan)(lan)橋架敷(fu)設。電(dian)(dian)(dian)纜(lan)(lan)作為供(gong)電(dian)(dian)(dian)主(zhu)干(gan)(gan)線(xian)(xian)比裸導(dao)線(xian)(xian)、裸排要得(de)多，但載流量受(shou)到限制(zhi)，電(dian)(dian)(dian)纜(lan)(lan)截(jie)面不可能造得(de)很大(da)（大(da)只(zhi)能做到４００ｍｍ２），而且(qie)電(dian)(dian)(dian)纜(lan)(lan)太粗，現場施工難度大(da)。８０年代中(zhong)(zhong)后(hou)期，城市發展迅(xun)速，高層(ceng)(ceng)(ceng)、超(chao)高層(ceng)(ceng)(ceng)建筑大(da)批建造，建筑物的(de)(de)(de)(de)用(yong)電(dian)(dian)(dian)負(fu)荷急劇增加，電(dian)(dian)(dian)纜(lan)(lan)作為供(gong)電(dian)(dian)(dian)主(zhu)干(gan)(gan)線(xian)(xian)的(de)(de)(de)(de)局限性(xing)越來越突出，特別是現場制(zhi)作電(dian)(dian)(dian)纜(lan)(lan)分支接頭技術(shu)難度很大(da)，急需一種容(rong)量大(da)、分支方便的(de)(de)(de)(de)供(gong)電(dian)(dian)(dian)主(zhu)干(gan)(gan)線(xian)(xian)取(qu)而代之。這時(shi)，容(rong)量大(da)、分支方便的(de)(de)(de)(de)母線(xian)(xian)槽從(cong)國外引進來，并且(qie)在(zai)工程中(zhong)(zhong)迅(xun)速得(de)到推廣應用(yong)。

體(ti)積(ji)非(fei)常的小(xiao)巧，所以在(zai)進行(xing)安裝的時候，無(wu)論(lun)是搬運還是運轉，都非(fei)常的便捷，只要少數(shu)幾(ji)人(ren)就可(ke)以完成。從變壓器連接(jie)(jie)(jie)一條(tiao)主(zhu)母(mu)線系統(tong)，根據(ju)廠房內(nei)用電設備的布局由主(zhu)母(mu)線引出分(fen)支(zhi)母(mu)線，在(zai)每(mei)條(tiao)分(fen)支(zhi)線路上預留(liu)多個插接(jie)(jie)(jie)口，以便向使(shi)用設備供電。插接(jie)(jie)(jie)式母(mu)線槽屬樹干式系統(tong)，具有(you)體(ti)積(ji)小(xiao)、結(jie)構緊湊、運行(xing)可(ke)靠、傳輸電流大(da)、便于分(fen)接(jie)(jie)(jie)饋電、維護方便、能耗小(xiao)、動熱穩定性好等優點，在(zai)高層(ceng)建筑中(zhong)得到廣泛應用。

母(mu)線(xian)(xian)(xian)(xian)槽(cao)(cao)(cao)的(de)(de)(de)型號上也有不(bu)同，不(bu)同的(de)(de)(de)母(mu)線(xian)(xian)(xian)(xian)槽(cao)(cao)(cao)的(de)(de)(de)工(gong)作(zuo)效率是(shi)不(bu)一(yi)(yi)樣的(de)(de)(de)，重(zhong)要(yao)的(de)(de)(de)是(shi)大(da)家(jia)要(yao)知道自己的(de)(de)(de)需求，母(mu)線(xian)(xian)(xian)(xian)槽(cao)(cao)(cao)設備，而(er)且(qie)選擇一(yi)(yi)個(ge)適合的(de)(de)(de)母(mu)線(xian)(xian)(xian)(xian)槽(cao)(cao)(cao)，才(cai)能(neng)夠(gou)保(bao)證工(gong)作(zuo)的(de)(de)(de)順(shun)利進(jin)行，否則型號分歧錯誤(wu)的(de)(de)(de)話，蚌(bang)埠母(mu)線(xian)(xian)(xian)(xian)槽(cao)(cao)(cao)，母(mu)線(xian)(xian)(xian)(xian)槽(cao)(cao)(cao)就可(ke)能(neng)沒辦法正(zheng)常工(gong)作(zuo)。所(suo)以說大(da)家(jia)在(zai)購買母(mu)線(xian)(xian)(xian)(xian)槽(cao)(cao)(cao)的(de)(de)(de)時候需要(yao)留意良多的(de)(de)(de)題目(mu)，母(mu)線(xian)(xian)(xian)(xian)槽(cao)(cao)(cao)規格(ge)，大(da)家(jia)只(zhi)有對母(mu)線(xian)(xian)(xian)(xian)操多做(zuo)一(yi)(yi)些了解，才(cai)能(neng)夠(gou)保(bao)證母(mu)線(xian)(xian)(xian)(xian)槽(cao)(cao)(cao)正(zheng)常的(de)(de)(de)工(gong)作(zuo)，同時也能(neng)夠(gou)利便我們(men)的(de)(de)(de)糊口和工(gong)作(zuo)。
