絕緣受潮：由于(yu)無(wu)(wu)(wu)鹵(lu)電(dian)(dian)子(zi)線(xian)(xian)路(lu)(lu)施工工藝(yi)差(cha)，濕(shi)氣侵入(ru)電(dian)(dian)子(zi)線(xian)(xian)路(lu)(lu)內部(bu)，或無(wu)(wu)(wu)鹵(lu)電(dian)(dian)子(zi)線(xian)(xian)路(lu)(lu)內保(bao)護層(ceng)損(sun)壞，濕(shi)氣進入(ru)無(wu)(wu)(wu)鹵(lu)電(dian)(dian)子(zi)線(xian)(xian)路(lu)(lu)；鉛(qian)包電(dian)(dian)纜敷設在(zai)震源(yuan)周圍，因(yin)(yin)長期振動而疲勞開裂，無(wu)(wu)(wu)鹵(lu)電(dian)(dian)子(zi)線(xian)(xian)路(lu)(lu)的(de)外(wai)皮(pi)被(bei)腐蝕并(bing)漂浮，由于(yu)制(zhi)造(zao)質量不好(hao)，鉛(qian)包上有(you)小孔或裂紋；鑒于(yu)這些現象(xiang)，應加(jia)強無(wu)(wu)(wu)鹵(lu)電(dian)(dian)子(zi)線(xian)(xian)路(lu)(lu)外(wai)層(ceng)的(de)維(wei)護，并(bing)按期在(zai)外(wai)保(bao)護層(ceng)上涂一層(ceng)瀝青。過(guo)(guo)電(dian)(dian)壓：無(wu)(wu)(wu)鹵(lu)電(dian)(dian)子(zi)線(xian)(xian)路(lu)(lu)絕緣層(ceng)因(yin)(yin)大氣過(guo)(guo)電(dian)(dian)壓或內部(bu)過(guo)(guo)電(dian)(dian)壓而擊穿，特別是系統內部(bu)過(guo)(guo)電(dian)(dian)壓會導致多根電(dian)(dian)纜同時擊穿，在(zai)這方面(mian)，應安裝避雷(lei)器。

絕(jue)(jue)緣老化：在(zai)無鹵(lu)電(dian)(dian)子線路的長期(qi)運行(xing)過程中(zhong)，由于(yu)散熱不良或(huo)過載，絕(jue)(jue)緣材料(liao)的電(dian)(dian)氣(qi)和機械功(gong)能(neng)變差，絕(jue)(jue)緣層變脆或(huo)斷裂，如果是(shi)這種情況，應定期(qi)對無鹵(lu)素電(dian)(dian)子線路進行(xing)預防性(xing)耐壓(ya)測試，在(zai)無鹵(lu)電(dian)(dian)子線路絕(jue)(jue)緣降低不符合安全運行(xing)條件(jian)，應更換(huan)新電(dian)(dian)纜(lan)。
