母(mu)(mu)線(xian)槽(cao)(cao)，是由銅、鋁母(mu)(mu)線(xian)柱(zhu)構成的(de)一種封(feng)閉的(de)金屬裝置，密集型封(feng)閉母(mu)(mu)線(xian)槽(cao)(cao)廠(chang)，用來為分(fen)散系統各個(ge)元件分(fen)配(pei)較大功率。在一些國家和城(cheng)市，凡12層以上樓宇配(pei)電(dian)(dian)房出線(xian)，即(ji)引至樓層的(de)主干線(xian)90%以上使(shi)用母(mu)(mu)線(xian)槽(cao)(cao)；630KVA變壓器至配(pei)電(dian)(dian)柜要使(shi)用母(mu)(mu)線(xian)槽(cao)(cao)。選用母(mu)(mu)線(xian)槽(cao)(cao)有許多(duo)性，蚌埠密集型母(mu)(mu)線(xian)槽(cao)(cao)，在低壓配(pei)電(dian)(dian)系統輸(shu)電(dian)(dian)干線(xian)工程項目中得到(dao)廣泛地(di)應用，越來越多(duo)地(di)代替了(le)電(dian)(dian)纜。

母線(xian)(xian)槽(cao)一(yi)般應用(yong)(yong)的(de)(de)(de)行業有：專門的(de)(de)(de)安(an)(an)裝公(gong)司(si)，新建的(de)(de)(de)廠(chang)房等建筑(zhu)，走(zou)電(dian)纜的(de)(de)(de)時候都需要母線(xian)(xian)槽(cao)。重點(dian)關(guan)注(zhu)電(dian)路(lu)較(jiao)復(fu)雜的(de)(de)(de)地方，他們對(dui)母線(xian)(xian)槽(cao)的(de)(de)(de)用(yong)(yong)量較(jiao)大，如(ru)換流站，地鐵、機場，密集型絕緣(yuan)母線(xian)(xian)槽(cao)，發電(dian)站，站，密集型母線(xian)(xian)槽(cao)安(an)(an)裝，現(xian)代化廠(chang)房等等。二(er)次(ci)母線(xian)(xian)槽(cao)主要是(shi)變電(dian)站使用(yong)(yong)，二(er)次(ci)是(shi)相(xiang)對(dui)于(yu)一(yi)次(ci)來說的(de)(de)(de)，其(qi)實說白(bai)了這(zhe)就是(shi)一(yi)常(chang)用(yong)(yong)的(de)(de)(de)說法，二(er)次(ci)母線(xian)(xian)槽(cao)也是(shi)母線(xian)(xian)槽(cao)，根(gen)(gen)據加工安(an)(an)裝形式分為(wei)梯式母線(xian)(xian)槽(cao)和槽(cao)式母線(xian)(xian)槽(cao)，可以根(gen)(gen)據電(dian)纜規模和設計要求采用(yong)(yong)多層布置的(de)(de)(de)方法。

母(mu)(mu)(mu)(mu)線(xian)(xian)(xian)(xian)槽(cao)(cao)按絕緣(yuan)方(fang)式(shi)可分(fen)(fen)為空氣(qi)式(shi)插接(jie)(jie)母(mu)(mu)(mu)(mu)線(xian)(xian)(xian)(xian)槽(cao)(cao)、密集絕緣(yuan)插接(jie)(jie)母(mu)(mu)(mu)(mu)線(xian)(xian)(xian)(xian)槽(cao)(cao)和(he)(he)高強度(du)(du)插接(jie)(jie)母(mu)(mu)(mu)(mu)線(xian)(xian)(xian)(xian)槽(cao)(cao)三(san)種(zhong)。母(mu)(mu)(mu)(mu)線(xian)(xian)(xian)(xian)槽(cao)(cao)雖然優點眾(zhong)多，但在被使用范(fan)圍(wei)內，特(te)別容易對不(bu)同程(cheng)度(du)(du)的海拔(ba)高度(du)(du)、周(zhou)圍(wei)空氣(qi)溫度(du)(du)、空氣(qi)清潔程(cheng)度(du)(du)感冒。按用途區分(fen)(fen)母(mu)(mu)(mu)(mu)線(xian)(xian)(xian)(xian)槽(cao)(cao)一般(ban)由始端母(mu)(mu)(mu)(mu)線(xian)(xian)(xian)(xian)槽(cao)(cao)、直通母(mu)(mu)(mu)(mu)線(xian)(xian)(xian)(xian)槽(cao)(cao)（分(fen)(fen)帶插孔和(he)(he)不(bu)帶插孔兩種(zhong)）、L型垂直（水(shui)平(ping)(ping)）彎(wan)通母(mu)(mu)(mu)(mu)線(xian)(xian)(xian)(xian)、Z型垂直（水(shui)平(ping)(ping)）偏置(zhi)母(mu)(mu)(mu)(mu)線(xian)(xian)(xian)(xian)、T型垂直（水(shui)平(ping)(ping)）三(san)通母(mu)(mu)(mu)(mu)線(xian)(xian)(xian)(xian)、X型垂直（水(shui)平(ping)(ping)）四(si)通母(mu)(mu)(mu)(mu)線(xian)(xian)(xian)(xian)等組成。
