母線槽由于供(gong)電容量大，安(an)全可靠，安(an)裝方(fang)便，自上個世紀(ji)80年(nian)代引入我國以(yi)來，隨著中國工程建設的飛(fei)速發(fa)展而得到了迅猛的帶動發(fa)展。

在高層締造(zao)的(de)供(gong)電(dian)(dian)系統中(zhong)，供(gong)電(dian)(dian)主(zhu)(zhu)干線(xian)起著非(fei)常關緊的(de)功(gong)(gong)效，它(ta)恰似(si)人體中(zhong)的(de)主(zhu)(zhu)動脈，一朝呈現故障便會導致嚴峻的(de)結(jie)果。故此，出(chu)產、締造(zao)及科(ke)研單位一向在為供(gong)電(dian)(dian)主(zhu)(zhu)干線(xian)的(de)靠(kao)得住性作出(chu)黽勉，不斷改進，以期創造(zao)出(chu)裝置(zhi)維護簡(jian)潔、質優價廉(lian)、功(gong)(gong)能安定(ding)的(de)新產品。

室內(nei)導(dao)線(xian)(xian)(xian)敷(fu)設形式可分為：明敷(fu)——導(dao)線(xian)(xian)(xian)直(zhi)接仍(reng)(reng)是(shi)在管子、線(xian)(xian)(xian)槽(cao)等(deng)保證(zheng)體內(nei)?敷(fu)設于墻(qiang)面(mian)、頂棚的表面(mian)及(ji)桁(heng)架(jia)、支架(jia)等(deng)處；暗敷(fu)——導(dao)線(xian)(xian)(xian)在管子、線(xian)(xian)(xian)槽(cao)等(deng)保證(zheng)體內(nei)?敷(fu)設于墻(qiang)面(mian)、頂棚、地坪及(ji)樓板(ban)等(deng)內(nei)部，仍(reng)(reng)是(shi)在水泥(ni)板(ban)孔內(nei)敷(fu)線(xian)(xian)(xian)等(deng)。關(guan)于小型締(di)造，用電載荷(he)不是(shi)巨大，主干線(xian)(xian)(xian)往往選用絕緣(yuan)導(dao)線(xian)(xian)(xian)；關(guan)于高層締(di)造，用電載荷(he)較大，用絕緣(yuan)導(dao)線(xian)(xian)(xian)作為主干線(xian)(xian)(xian)已不得知足供(gong)電需求，這時主干線(xian)(xian)(xian)需求用電纜或母線(xian)(xian)(xian)槽(cao)。

80年(nian)代曾經，高層締(di)造(zao)中的(de)(de)供(gong)(gong)電(dian)(dian)主(zhu)(zhu)干(gan)線(xian)(xian)首(shou)要(yao)選(xuan)用靠得(de)住(zhu)性(xing)(xing)較(jiao)好的(de)(de)普(pu)通(tong)電(dian)(dian)纜(lan)(lan)，電(dian)(dian)纜(lan)(lan)在(zai)電(dian)(dian)氣豎井內沿墻(qiang)面(mian)用支架或電(dian)(dian)纜(lan)(lan)橋架敷設。電(dian)(dian)纜(lan)(lan)作為供(gong)(gong)電(dian)(dian)主(zhu)(zhu)干(gan)線(xian)(xian)比(bi)裸(luo)(luo)導線(xian)(xian)、裸(luo)(luo)排(pai)要(yao)安全(quan)賴(lai)得(de)住(zhu)得(de)多(duo)，但(dan)載流(liu)量遭受限止，電(dian)(dian)纜(lan)(lan)剖面(mian)不可(ke)能(neng)造(zao)得(de)巨(ju)大(da)（最大(da)只能(neng)做到400mm2），并且電(dian)(dian)纜(lan)(lan)太(tai)粗，在(zai)場施(shi)工高難。80年(nian)代中后(hou)期，城市發(fa)展(zhan)迅疾(ji)，高層、超(chao)高層締(di)造(zao)很多(duo)建立，牌樓的(de)(de)用電(dian)(dian)載荷急劇增加，電(dian)(dian)纜(lan)(lan)作為供(gong)(gong)電(dian)(dian)主(zhu)(zhu)干(gan)線(xian)(xian)的(de)(de)局限性(xing)(xing)越來(lai)越冒尖(jian)，出奇(qi)是在(zai)場制造(zao)電(dian)(dian)纜(lan)(lan)分支接頭技能(neng)難度巨(ju)大(da)，急需一種容積大(da)、分支快捷(jie)的(de)(de)供(gong)(gong)電(dian)(dian)主(zhu)(zhu)干(gan)線(xian)(xian)取而代之。這時，容積大(da)、分支快捷(jie)的(de)(de)母(mu)線(xian)(xian)槽從海外引進來(lai)，并且在(zai)工程中迅疾(ji)達到推廣應(ying)用。
