絕(jue)緣受潮：由于無(wu)(wu)鹵(lu)(lu)(lu)(lu)電(dian)子(zi)(zi)線(xian)(xian)路施(shi)工工藝(yi)差，濕(shi)氣侵(qin)入電(dian)子(zi)(zi)線(xian)(xian)路內(nei)部(bu)，或(huo)無(wu)(wu)鹵(lu)(lu)(lu)(lu)電(dian)子(zi)(zi)線(xian)(xian)路內(nei)保(bao)護(hu)(hu)層(ceng)損壞，濕(shi)氣進入無(wu)(wu)鹵(lu)(lu)(lu)(lu)電(dian)子(zi)(zi)線(xian)(xian)路；鉛包電(dian)纜敷設(she)在(zai)(zai)震源周圍(wei)，因長期(qi)(qi)振動而(er)疲勞開裂(lie)，無(wu)(wu)鹵(lu)(lu)(lu)(lu)電(dian)子(zi)(zi)線(xian)(xian)路的外皮被腐蝕并漂浮，由于制造質(zhi)量不好(hao)，鉛包上有小孔(kong)或(huo)裂(lie)紋；鑒(jian)于這些現象(xiang)，應(ying)加(jia)強無(wu)(wu)鹵(lu)(lu)(lu)(lu)電(dian)子(zi)(zi)線(xian)(xian)路外層(ceng)的維(wei)護(hu)(hu)，并按期(qi)(qi)在(zai)(zai)外保(bao)護(hu)(hu)層(ceng)上涂一層(ceng)瀝青(qing)。過(guo)電(dian)壓(ya)：無(wu)(wu)鹵(lu)(lu)(lu)(lu)電(dian)子(zi)(zi)線(xian)(xian)路絕(jue)緣層(ceng)因大氣過(guo)電(dian)壓(ya)或(huo)內(nei)部(bu)過(guo)電(dian)壓(ya)而(er)擊穿，特別是(shi)系(xi)統內(nei)部(bu)過(guo)電(dian)壓(ya)會(hui)導致多根電(dian)纜同時擊穿，在(zai)(zai)這方(fang)面(mian)，應(ying)安裝(zhuang)避雷(lei)器。

絕緣老化(hua)：在(zai)(zai)無(wu)鹵(lu)電子線路的長期(qi)運行(xing)過(guo)程中，由于散(san)熱不(bu)良或過(guo)載，絕緣材料的電氣(qi)和機械(xie)功能變差，絕緣層變脆(cui)或斷裂，如果是這種情況，應定期(qi)對無(wu)鹵(lu)素電子線路進行(xing)預(yu)防性耐壓(ya)測試，在(zai)(zai)無(wu)鹵(lu)電子線路絕緣降低(di)不(bu)符合安全(quan)運行(xing)條件，應更換新(xin)電纜。
