中間接(jie)線盒絕緣擊(ji)穿：由于電(dian)(dian)纜(lan)連(lian)接(jie)盒中間接(jie)頭(tou)(tou)有(you)松(song)(song)動、焊接(jie)松(song)(song)動或接(jie)頭(tou)(tou)材料選(xuan)擇(ze)不(bu)當，運行中氧化(hua)、發(fa)熱(re)、出膠等(deng)；電(dian)(dian)纜(lan)中間接(jie)頭(tou)(tou)注入接(jie)頭(tou)(tou)盒的絕緣劑(ji)質量不(bu)合(he)格(ge)。澆鑄絕緣劑(ji)時，箱(xiang)內有(you)氣孔，亨通高壓電(dian)(dian)纜(lan)，電(dian)(dian)纜(lan)箱(xiang)密封不(bu)良(liang)，漏(lou)潮現象。以(yi)上因素(su)會造(zao)成(cheng)絕緣擊(ji)穿，形成(cheng)短(duan)路，造(zao)成(cheng)電(dian)(dian)纜(lan)及火(huo)災。

電(dian)纜頭(tou)(tou)燒損：由于纜頭(tou)(tou)表(biao)面水份(fen)和污垢，造成電(dian)纜頭(tou)(tou)瓷套斷裂，引線間距太小(xiao)，引起閃絡和火災，造成纜頭(tou)(tou)表(biao)層絕(jue)緣(yuan)燒損及導線絕(jue)緣(yuan)燒損。

外部火源和熱源引起的電纜火災：如油系統發火、油斷路器、鍋爐制粉系統或輸煤系統煤粉自燃、高溫蒸氣管道烘烤、酸堿化學腐蝕等，焊接火花及其它火種可能導致電纜著火。

電線電纜的(de)維護：機(ji)器(qi)(qi)周圍應隨時(shi)保持干(gan)凈整潔。不得(de)有(you)油污、水或(huo)(huo)材料或(huo)(huo)產品掉落地面(mian)。生產造成的(de)廢品要及時(shi)集中(zhong)(zhong)，迅速(su)處理。擦拭和清潔機(ji)器(qi)(qi)表面(mian)以及機(ji)器(qi)(qi)是(shi)否得(de)到(dao)(dao)良好(hao)(hao)(hao)維護。查(cha)(cha)看機(ji)器(qi)(qi)表面(mian)是(shi)否始(shi)終清潔，工(gong)具是(shi)否按規定(ding)放(fang)置，機(ji)器(qi)(qi)表面(mian)是(shi)否放(fang)置了(le)不應放(fang)置的(de)物品；按規定(ding)添加潤滑油或(huo)(huo)冷卻(que)油，并定(ding)期檢查(cha)(cha)供油系統是(shi)否暢通；機(ji)器(qi)(qi)運行過程中(zhong)(zhong)，有(you)無(wu)異常(chang)聲音或(huo)(huo)振動(dong)，定(ding)期檢查(cha)(cha)和緊固緊固件(jian)；傳動(dong)帶(dai)在使(shi)用(yong)過程中(zhong)(zhong)是(shi)否松(song)動(dong)或(huo)(huo)變質，應更換；所有(you)機(ji)器(qi)(qi)安全門、安全柵、安全罩、安全開關和限(xian)位裝置是(shi)否齊全、正常(chang)、有(you)效(xiao)；根據理貨卡(ka)的(de)要求，操作人員須做(zuo)到(dao)(dao)“三好(hao)(hao)(hao)”和“四會”；即管(guan)理好(hao)(hao)(hao)、使(shi)用(yong)好(hao)(hao)(hao)、維護好(hao)(hao)(hao)；能夠使(shi)用(yong)、檢查(cha)(cha)、維護和排除(chu)故障(zhang)。控(kong)制電纜的(de)維護工(gong)作也需做(zuo)到(dao)(dao)位。

電線單股(gu)和多股(gu)的區(qu)別

單股電(dian)線(xian)(xian)(xian)的每(mei)一(yi)(yi)根(gen)(gen)電(dian)線(xian)(xian)(xian)，是由(you)單一(yi)(yi)的一(yi)(yi)根(gen)(gen)粗電(dian)線(xian)(xian)(xian)組成(cheng)的，又叫做硬線(xian)(xian)(xian)；而多股電(dian)線(xian)(xian)(xian)的每(mei)一(yi)(yi)根(gen)(gen)電(dian)線(xian)(xian)(xian)，則是由(you)多個細銅絲組成(cheng)的一(yi)(yi)根(gen)(gen)電(dian)線(xian)(xian)(xian)，又叫做軟線(xian)(xian)(xian)。

裝修適合用(yong)單股(gu)線(xian)(xian)(xian)還(huan)是用(yong)多(duo)(duo)(duo)股(gu)線(xian)(xian)(xian)？1、施(shi)工方面(mian)：多(duo)(duo)(duo)股(gu)電線(xian)(xian)(xian)容易(yi)施(shi)工：由于單股(gu)線(xian)(xian)(xian)是用(yong)一根粗銅(tong)線(xian)(xian)(xian)制作成的(de)(de)，相對(dui)多(duo)(duo)(duo)股(gu)來說，有(you)點(dian)硬，所以(yi)在(zai)施(shi)工穿線(xian)(xian)(xian)的(de)(de)時(shi)候，相對(dui)比較(jiao)難穿線(xian)(xian)(xian)；而多(duo)(duo)(duo)股(gu)的(de)(de)電線(xian)(xian)(xian)，穿線(xian)(xian)(xian)的(de)(de)時(shi)候就容易(yi)多(duo)(duo)(duo)了。2、散(san)(san)熱(re)方面(mian)：多(duo)(duo)(duo)股(gu)電線(xian)(xian)(xian)散(san)(san)熱(re)占(zhan)有(you)一定(ding)(ding)優(you)勢(shi)多(duo)(duo)(duo)股(gu)電線(xian)(xian)(xian)是由多(duo)(duo)(duo)個細(xi)銅(tong)絲組成的(de)(de)，銅(tong)絲與(yu)銅(tong)絲之間有(you)一定(ding)(ding)的(de)(de)間隙(xi)，所以(yi)散(san)(san)熱(re)方面(mian)占(zhan)有(you)一定(ding)(ding)的(de)(de)優(you)勢(shi)。3、是否(fou)容易(yi)氧(yang)化(hua)：單股(gu)線(xian)(xian)(xian)不(bu)容易(yi)氧(yang)化(hua)? 4、價格(ge)方面(mian)：單股(gu)線(xian)(xian)(xian)價格(ge)相對(dui)便宜
