任何一個樓(lou)面(mian)需(xu)要(yao)(yao)切(qie)斷(duan)(duan)電(dian)(dian)(dian)源(yuan)(yuan)，母(mu)線(xian)槽(cao)(cao)無須斷(duan)(duan)電(dian)(dian)(dian)，只(zhi)要(yao)(yao)在(zai)空載的(de)(de)(de)情(qing)況(kuang)下(xia)，取下(xia)母(mu)線(xian)槽(cao)(cao)的(de)(de)(de)插接箱即(ji)可。但要(yao)(yao)切(qie)斷(duan)(duan)預制分(fen)支(zhi)電(dian)(dian)(dian)纜(lan)(lan)(lan)的(de)(de)(de)分(fen)支(zhi)電(dian)(dian)(dian)源(yuan)(yuan)，在(zai)帶電(dian)(dian)(dian)的(de)(de)(de)情(qing)況(kuang)下(xia)操作是十分(fen)危險的(de)(de)(de)。 ?母(mu)線(xian)槽(cao)(cao)能(neng)防(fang)(fang)止過載，普通電(dian)(dian)(dian)纜(lan)(lan)(lan)的(de)(de)(de)絕(jue)緣(yuan)(yuan)層和(he)外(wai)皮(pi)會(hui)燃(ran)燒，阻(zu)燃(ran)電(dian)(dian)(dian)纜(lan)(lan)(lan)在(zai)火焰下(xia)也會(hui)燃(ran)燒，紅河鋁合金母(mu)線(xian)槽(cao)(cao)，只(zhi)有在(zai)火焰離開后才(cai)(cai)不(bu)燃(ran)燒，耐(nai)火電(dian)(dian)(dian)纜(lan)(lan)(lan)不(bu)會(hui)燃(ran)燒，鋁合金母(mu)線(xian)槽(cao)(cao)報價，但價格(ge)昂貴，鋁合金母(mu)線(xian)槽(cao)(cao)批發，只(zhi)有消防(fang)(fang)等不(bu)準(zhun)停電(dian)(dian)(dian)的(de)(de)(de)電(dian)(dian)(dian)源(yuan)(yuan)才(cai)(cai)用(yong)耐(nai)火電(dian)(dian)(dian)纜(lan)(lan)(lan)。母(mu)線(xian)槽(cao)(cao)外(wai)殼是金屬(shu)的(de)(de)(de)，不(bu)會(hui)燃(ran)燒，即(ji)使(shi)銅排的(de)(de)(de)絕(jue)緣(yuan)(yuan)材料發生燃(ran)燒，火苗也不(bu)會(hui)竄(cuan)到母(mu)線(xian)槽(cao)(cao)外(wai)面(mian)。

曲(qu)面圖(tu)形可看成動(dong)線(xian)運動(dong)時的(de)軌跡，形成曲(qu)面的(de)動(dong)線(xian)稱為母線(xian)。比如圓錐(zhui)的(de)主視(shi)圖(tu)是一(yi)個等腰三角(jiao)形，這(zhe)個三角(jiao)形的(de)腰就是圓錐(zhui)母線(xian)。

控制母線(xian)(xian)運(yun)(yun)動(dong)的(de)線(xian)(xian)或面，稱(cheng)(cheng)為(wei)(wei)導(dao)線(xian)(xian)或導(dao)面，母線(xian)(xian)在曲(qu)(qu)面上任一位置，稱(cheng)(cheng)為(wei)(wei)素線(xian)(xian)，鋁合(he)金母線(xian)(xian)槽廠，線(xian)(xian)低壓母曲(qu)(qu)線(xian)(xian)AB為(wei)(wei)導(dao)線(xian)(xian)，直線(xian)(xian)SB為(wei)(wei)母線(xian)(xian)，SB運(yun)(yun)動(dong)的(de)各個位置為(wei)(wei)素線(xian)(xian)。母線(xian)(xian)為(wei)(wei)直線(xian)(xian)時(shi)所形(xing)(xing)成(cheng)的(de)曲(qu)(qu)面中心(xin)稱(cheng)(cheng)為(wei)(wei)母線(xian)(xian)作規則(ze)運(yun)(yun)動(dong)時(shi)所形(xing)(xing)成(cheng)的(de)曲(qu)(qu)面稱(cheng)(cheng)為(wei)(wei)規則(ze)曲(qu)(qu)面。控制母線(xian)(xian)運(yun)(yun)動(dong)的(de)備寒雄牛(niu)點線(xian)(xian)面稱(cheng)(cheng)之為(wei)(wei)導(dao)線(xian)(xian)。

通過使用(yong)母(mu)線(xian)槽，可以合并(bing)某些分支(zhi)回路，并(bing)用(yong)插接箱將(jiang)之轉(zhuan)化為一條大(da)的(de)母(mu)線(xian)槽。它可簡化電(dian)(dian)氣系統，得到較多(duo)股線(xian)低的(de)電(dian)(dian)流(liu)值。因此節約了工程的(de)造價，并(bing)且易于(yu)(yu)維護。對(dui)于(yu)(yu)傳統的(de)電(dian)(dian)纜線(xian)路，電(dian)(dian)纜會使得電(dian)(dian)氣系統極其復雜(za)，龐大(da)，難于(yu)(yu)維護，插接式母(mu)線(xian)槽這樣，母(mu)線(xian)就浪費了工程費用(yong)和安裝(zhuang)空間。

對于母線(xian)來講，系統擴展可通過增加或改變(bian)若干段來完(wan)成，重新(xin)(xin)利(li)用率高。而大多數情況下，電(dian)纜(lan)不(bu)能重新(xin)(xin)利(li)用，因為長(chang)度和路(lu)線(xian)是不(bu)同的，如果要擴展系統，我們要購買新(xin)(xin)的電(dian)纜(lan)取代舊的電(dian)纜(lan)。
