母(mu)(mu)線槽(cao)的便(bian)捷維(wei)護(hu)：母(mu)(mu)線槽(cao)幾(ji)乎免維(wei)護(hu)。日常維(wei)護(hu)通常是(shi)測量外(wai)殼和芯螺栓的溫度升(sheng)高(gao)，共(gong)箱母(mu)(mu)線槽(cao)公司，進線盒(he)連接器的溫度升(sheng)高(gao)等。如(ru)果芯螺栓為4.8級，則需要定期擰緊。如(ru)果使用8.8級高(gao)強(qiang)度螺栓，則無(wu)需定期加(jia)固。

過載(zai)時母(mu)線(xian)槽(cao)堅固：過載(zai)時母(mu)線(xian)槽(cao)堅固，這取決于所(suo)用絕(jue)緣(yuan)材料(liao)的(de)工(gong)作溫度(du)高。用于母(mu)線(xian)槽(cao)的(de)絕(jue)緣(yuan)材料(liao)是使用工(gong)作溫度(du)為(wei)105℃的(de)材料(liao)過度(du)支撐(cheng)的(de)，并(bing)且已經(jing)開(kai)發并(bing)接受，工(gong)作溫度(du)為(wei)140。輻(fu)射交聯阻燃(ran)纏(chan)繞(rao)帶和輻(fu)射交聯聚(ju)碳(tan)酸酯熱縮管℃以上。但(dan)是，共箱母(mu)線(xian)槽(cao)供(gong)應(ying)，電纜(lan)使用的(de)絕(jue)緣(yuan)材料(liao)的(de)正常工(gong)作溫度(du)為(wei)95℃和105℃，因此母(mu)線(xian)槽(cao)的(de)過載(zai)可能遠大于電纜(lan)的(de)過載(zai)。

選用(yong)母(mu)(mu)(mu)(mu)線(xian)槽(cao)時應綜合(he)考慮使用(yong)環(huan)境，母(mu)(mu)(mu)(mu)線(xian)槽(cao)的外殼(ke)防(fang)(fang)護等(deng)(deng)級(ji)選擇應符合(he)下列規定：1.室內潔(jie)凈場(chang)(chang)所，采用(yong)IP30及(ji)以級(ji)。2.室內普通場(chang)(chang)所，采用(yong)不(bu)低(di)于IP40等(deng)(deng)級(ji)。3.室內有(you)防(fang)(fang)濺水(shui)要(yao)求的場(chang)(chang)所，采用(yong)不(bu)低(di)于IP54等(deng)(deng)級(ji)。4.室內潮濕場(chang)(chang)所或有(you)防(fang)(fang)噴(pen)水(shui)要(yao)求的場(chang)(chang)所，采用(yong)IP65及(ji)以級(ji)。5.有(you)防(fang)(fang)腐要(yao)求的場(chang)(chang)所或室外，玉溪共(gong)箱母(mu)(mu)(mu)(mu)線(xian)槽(cao)，采用(yong)IP68等(deng)(deng)級(ji)的全(quan)封閉樹(shu)脂(zhi)澆注母(mu)(mu)(mu)(mu)線(xian)槽(cao)。封閉式(shi)(shi)(shi)母(mu)(mu)(mu)(mu)線(xian)槽(cao)簡(jian)稱母(mu)(mu)(mu)(mu)線(xian)槽(cao)。封閉式(shi)(shi)(shi)母(mu)(mu)(mu)(mu)線(xian)槽(cao)和母(mu)(mu)(mu)(mu)線(xian)槽(cao)指的是(shi)同一個東西。封閉式(shi)(shi)(shi)母(mu)(mu)(mu)(mu)線(xian)槽(cao)是(shi)由(you)金(jin)屬板（鋼(gang)板或鋁板）作為保護殼(ke)、導電條(tiao)、絕(jue)(jue)(jue)(jue)緣(yuan)(yuan)材料(liao)及(ji)相關附(fu)件組成的母(mu)(mu)(mu)(mu)線(xian)系統。可(ke)(ke)制成間隔插(cha)(cha)入(ru)式(shi)(shi)(shi)接線(xian)盒的插(cha)(cha)入(ru)式(shi)(shi)(shi)封閉母(mu)(mu)(mu)(mu)線(xian)，也可(ke)(ke)制成中間不(bu)帶接線(xian)盒的饋電式(shi)(shi)(shi)封閉母(mu)(mu)(mu)(mu)線(xian)。封閉式(shi)(shi)(shi)母(mu)(mu)(mu)(mu)線(xian)槽(cao)（母(mu)(mu)(mu)(mu)線(xian)槽(cao)）按(an)(an)絕(jue)(jue)(jue)(jue)緣(yuan)(yuan)方(fang)式(shi)(shi)(shi)可(ke)(ke)分為空氣(qi)插(cha)(cha)入(ru)式(shi)(shi)(shi)母(mu)(mu)(mu)(mu)線(xian)槽(cao)、密絕(jue)(jue)(jue)(jue)緣(yuan)(yuan)插(cha)(cha)入(ru)式(shi)(shi)(shi)母(mu)(mu)(mu)(mu)線(xian)槽(cao)和高強(qiang)度插(cha)(cha)入(ru)式(shi)(shi)(shi)母(mu)(mu)(mu)(mu)線(xian)槽(cao)三(san)種。按(an)(an)其結構和用(yong)途分為致密絕(jue)(jue)(jue)(jue)緣(yuan)(yuan)、空氣(qi)絕(jue)(jue)(jue)(jue)緣(yuan)(yuan)、空氣(qi)附(fu)加絕(jue)(jue)(jue)(jue)緣(yuan)(yuan)、耐火、樹(shu)脂(zhi)絕(jue)(jue)(jue)(jue)緣(yuan)(yuan)和滑觸式(shi)(shi)(shi)母(mu)(mu)(mu)(mu)線(xian)槽(cao)；按(an)(an)外殼(ke)材料(liao)分為鋼(gang)殼(ke)、鋁合(he)金(jin)殼(ke)和鋼(gang)鋁混(hun)合(he)殼(ke)母(mu)(mu)(mu)(mu)線(xian)槽(cao)。

按用(yong)途，母(mu)(mu)線(xian)(xian)槽(cao)一般由始端(duan)(duan)母(mu)(mu)線(xian)(xian)槽(cao)、直通(tong)(tong)母(mu)(mu)線(xian)(xian)槽(cao)（分帶插孔(kong)和不帶插孔(kong)兩種(zhong)）、L型(xing)垂直（水平(ping)(ping)）彎通(tong)(tong)母(mu)(mu)線(xian)(xian)、Z型(xing)垂直（水平(ping)(ping)）偏置母(mu)(mu)線(xian)(xian)、T型(xing)垂直（水平(ping)(ping)）三通(tong)(tong)母(mu)(mu)線(xian)(xian)、X型(xing)垂直（水平(ping)(ping)）四通(tong)(tong)母(mu)(mu)線(xian)(xian)、變容母(mu)(mu)線(xian)(xian)槽(cao)、膨脹母(mu)(mu)線(xian)(xian)槽(cao)、終(zhong)端(duan)(duan)封頭、終(zhong)端(duan)(duan)接(jie)線(xian)(xian)箱、插接(jie)箱、母(mu)(mu)線(xian)(xian)槽(cao)有關附件及緊固裝(zhuang)置等組成的。

母(mu)(mu)線(xian)(xian)(xian)槽按(an)絕(jue)緣方(fang)(fang)(fang)式(shi)，可分為空(kong)氣(qi)式(shi)插接(jie)(jie)母(mu)(mu)線(xian)(xian)(xian)槽、密集(ji)絕(jue)緣插接(jie)(jie)母(mu)(mu)線(xian)(xian)(xian)槽和高(gao)強度插接(jie)(jie)母(mu)(mu)線(xian)(xian)(xian)槽三種。空(kong)氣(qi)式(shi)插接(jie)(jie)母(mu)(mu)線(xian)(xian)(xian)槽（BMC）。由于母(mu)(mu)線(xian)(xian)(xian)之(zhi)間(jian)接(jie)(jie)頭用銅(tong)片軟接(jie)(jie)過渡，在南方(fang)(fang)(fang)天(tian)氣(qi)潮濕，接(jie)(jie)頭之(zhi)間(jian)容易(yi)產生氧(yang)化，形成接(jie)(jie)頭與(yu)母(mu)(mu)線(xian)(xian)(xian)接(jie)(jie)觸(chu)不良，使(shi)觸(chu)頭容易(yi)發熱，故在南方(fang)(fang)(fang)使(shi)用。并且(qie)接(jie)(jie)頭之(zhi)間(jian)體積過大，水平(ping)母(mu)(mu)線(xian)(xian)(xian)段尺(chi)寸不一致，外(wai)形不夠美觀。
