母線(xian)(xian)(xian)(xian)槽(cao)分(fen)(fen)線(xian)(xian)(xian)(xian)的(de)(de)方便性(xing)：所謂的(de)(de)插(cha)(cha)入式母線(xian)(xian)(xian)(xian)槽(cao)，是指采用(yong)插(cha)(cha)入法(fa)將干線(xian)(xian)(xian)(xian)的(de)(de)電(dian)(dian)源分(fen)(fen)線(xian)(xian)(xian)(xian)到支(zhi)(zhi)(zhi)線(xian)(xian)(xian)(xian)，因此(ci)分(fen)(fen)線(xian)(xian)(xian)(xian)非(fei)常(chang)方便。預制分(fen)(fen)支(zhi)(zhi)(zhi)電(dian)(dian)纜的(de)(de)缺點是需要根據工廠定制。其(qi)分(fen)(fen)支(zhi)(zhi)(zhi)連接方法(fa)采用(yong)帶齒的(de)(de)“ C”形箍。隨著時間的(de)(de)流逝(shi)，可以確保箍緊(jin)嗎？另外(wai)，每個分(fen)(fen)支(zhi)(zhi)(zhi)頭的(de)(de)價(jia)格很高，共箱型母線(xian)(xian)(xian)(xian)槽(cao)報價(jia)，因此(ci)預制分(fen)(fen)支(zhi)(zhi)(zhi)電(dian)(dian)纜仍然沒有(you)被廣泛使用(yong)。如果任何樓層需要切(qie)斷(duan)電(dian)(dian)源，則無需關閉母線(xian)(xian)(xian)(xian)槽(cao)，只需在(zai)空載(zai)情況(kuang)下(xia)卸(xie)下(xia)母線(xian)(xian)(xian)(xian)槽(cao)的(de)(de)插(cha)(cha)入盒即(ji)可。但是，要切(qie)斷(duan)預制分(fen)(fen)支(zhi)(zhi)(zhi)電(dian)(dian)纜的(de)(de)分(fen)(fen)支(zhi)(zhi)(zhi)電(dian)(dian)源，在(zai)帶電(dian)(dian)條件下(xia)操作非(fei)常(chang)危險。

封(feng)(feng)閉(bi)(bi)式(shi)母(mu)(mu)(mu)(mu)(mu)(mu)線(xian)槽(cao)(cao)(cao)簡稱母(mu)(mu)(mu)(mu)(mu)(mu)線(xian)槽(cao)(cao)(cao)。封(feng)(feng)閉(bi)(bi)式(shi)母(mu)(mu)(mu)(mu)(mu)(mu)線(xian)槽(cao)(cao)(cao)和(he)(he)母(mu)(mu)(mu)(mu)(mu)(mu)線(xian)槽(cao)(cao)(cao)指的(de)(de)是同一個東西。封(feng)(feng)閉(bi)(bi)式(shi)母(mu)(mu)(mu)(mu)(mu)(mu)線(xian)槽(cao)(cao)(cao)是由金(jin)屬板(ban)（鋼(gang)板(ban)或鋁板(ban)）作為(wei)(wei)保護殼、導電條、絕(jue)緣(yuan)(yuan)(yuan)(yuan)材料及相關附件組成的(de)(de)母(mu)(mu)(mu)(mu)(mu)(mu)線(xian)系統。可(ke)(ke)制(zhi)成間隔插(cha)入(ru)(ru)(ru)式(shi)接線(xian)盒的(de)(de)插(cha)入(ru)(ru)(ru)式(shi)封(feng)(feng)閉(bi)(bi)母(mu)(mu)(mu)(mu)(mu)(mu)線(xian)，也可(ke)(ke)制(zhi)成中間不帶(dai)接線(xian)盒的(de)(de)饋電式(shi)封(feng)(feng)閉(bi)(bi)母(mu)(mu)(mu)(mu)(mu)(mu)線(xian)。封(feng)(feng)閉(bi)(bi)式(shi)母(mu)(mu)(mu)(mu)(mu)(mu)線(xian)槽(cao)(cao)(cao)（母(mu)(mu)(mu)(mu)(mu)(mu)線(xian)槽(cao)(cao)(cao)）按(an)絕(jue)緣(yuan)(yuan)(yuan)(yuan)方式(shi)可(ke)(ke)分(fen)為(wei)(wei)空氣(qi)(qi)插(cha)入(ru)(ru)(ru)式(shi)母(mu)(mu)(mu)(mu)(mu)(mu)線(xian)槽(cao)(cao)(cao)、密絕(jue)緣(yuan)(yuan)(yuan)(yuan)插(cha)入(ru)(ru)(ru)式(shi)母(mu)(mu)(mu)(mu)(mu)(mu)線(xian)槽(cao)(cao)(cao)和(he)(he)高(gao)強(qiang)度插(cha)入(ru)(ru)(ru)式(shi)母(mu)(mu)(mu)(mu)(mu)(mu)線(xian)槽(cao)(cao)(cao)三種。按(an)其(qi)結構和(he)(he)用途(tu)分(fen)為(wei)(wei)致密絕(jue)緣(yuan)(yuan)(yuan)(yuan)、空氣(qi)(qi)絕(jue)緣(yuan)(yuan)(yuan)(yuan)、空氣(qi)(qi)附加絕(jue)緣(yuan)(yuan)(yuan)(yuan)、耐(nai)火(huo)、樹脂絕(jue)緣(yuan)(yuan)(yuan)(yuan)和(he)(he)滑觸式(shi)母(mu)(mu)(mu)(mu)(mu)(mu)線(xian)槽(cao)(cao)(cao)；按(an)外殼材料分(fen)為(wei)(wei)鋼(gang)殼、鋁合(he)金(jin)殼和(he)(he)鋼(gang)鋁混合(he)殼母(mu)(mu)(mu)(mu)(mu)(mu)線(xian)槽(cao)(cao)(cao)。

復合絕緣型母線槽：

母線槽除了(le)導電排(pai)本(ben)身具有絕緣(yuan)(yuan)層外，共(gong)箱型母線槽廠，各(ge)(ge)相線之間還有一定的空氣介質(zhi)絕緣(yuan)(yuan)。在(zai)各(ge)(ge)種彎頭(tou)采用(yong)硫化絕緣(yuan)(yuan)技術。直線段采用(yong)MT-7-3橡膠套管。硫化絕緣(yuan)(yuan)技術：材(cai)料為CZ260快固(gu)絕緣(yuan)(yuan)粉(fen)末，采用(yong)四元(yuan)交聯固(gu)化，絕緣(yuan)(yuan)層與導電排(pai)間無間隙。其散(san)熱性(xing)(xing)能、防(fang)潮(chao)性(xing)(xing)能、絕緣(yuan)(yuan)可靠(kao)性(xing)(xing)能均優。

耐酸堿性(xing)能：硅(gui)橡(xiang)膠耐腐蝕性(xing)能也好，對(dui)于低濃度的(de)酸、堿、鹽的(de)耐受性(xing)能較好，如(ru)在10%的(de)硫酸中常溫浸漬7天，體積和(he)重量變化(hua)都小于1%，拉(la)斷力和(he)斷裂伸長率基(ji)本沒有(you)變化(hua)。

環(huan)保性：與母線槽一(yi)(yi)樣，硅(gui)橡膠無(wu)害無(wu)臭，是一(yi)(yi)種(zhong)環(huan)保材料。傳統(tong)的母線槽外(wai)殼采用鋁合(he)金(jin)材料，共箱(xiang)型(xing)母線槽生產商，既輕便(bian)，昆(kun)明共箱(xiang)型(xing)母線槽，強度又高，節(jie)約了成本，同時(shi)，可(ke)以使母線槽的使用壽命大(da)大(da)延長。
