絕緣受潮：由(you)(you)于(yu)無(wu)(wu)(wu)鹵(lu)電(dian)(dian)(dian)子線(xian)路(lu)(lu)施工工藝差，濕(shi)氣(qi)侵(qin)入電(dian)(dian)(dian)子線(xian)路(lu)(lu)內部(bu)，或(huo)無(wu)(wu)(wu)鹵(lu)電(dian)(dian)(dian)子線(xian)路(lu)(lu)內保(bao)護層(ceng)(ceng)損壞，濕(shi)氣(qi)進入無(wu)(wu)(wu)鹵(lu)電(dian)(dian)(dian)子線(xian)路(lu)(lu)；鉛(qian)包(bao)(bao)電(dian)(dian)(dian)纜敷(fu)設(she)在震源周圍，因(yin)長期(qi)振動而疲勞開裂(lie)，無(wu)(wu)(wu)鹵(lu)電(dian)(dian)(dian)子線(xian)路(lu)(lu)的(de)(de)外皮被腐蝕并(bing)漂浮，由(you)(you)于(yu)制造質(zhi)量不好(hao)，鉛(qian)包(bao)(bao)上(shang)有小孔或(huo)裂(lie)紋；鑒于(yu)這些現(xian)象，應(ying)加強(qiang)無(wu)(wu)(wu)鹵(lu)電(dian)(dian)(dian)子線(xian)路(lu)(lu)外層(ceng)(ceng)的(de)(de)維(wei)護，并(bing)按期(qi)在外保(bao)護層(ceng)(ceng)上(shang)涂(tu)一層(ceng)(ceng)瀝青(qing)。過(guo)電(dian)(dian)(dian)壓：無(wu)(wu)(wu)鹵(lu)電(dian)(dian)(dian)子線(xian)路(lu)(lu)絕緣層(ceng)(ceng)因(yin)大氣(qi)過(guo)電(dian)(dian)(dian)壓或(huo)內部(bu)過(guo)電(dian)(dian)(dian)壓而擊(ji)穿，特別是系(xi)統內部(bu)過(guo)電(dian)(dian)(dian)壓會(hui)導致多(duo)根電(dian)(dian)(dian)纜同時擊(ji)穿，在這方面，應(ying)安裝避雷器。

絕緣老(lao)化：在無(wu)鹵電(dian)(dian)子(zi)(zi)線(xian)(xian)路(lu)(lu)的長期運(yun)行過程中，由于散熱不良或(huo)過載(zai)，絕緣材(cai)料的電(dian)(dian)氣和(he)機械功能變(bian)差，絕緣層變(bian)脆或(huo)斷裂(lie)，如果(guo)是這種(zhong)情況，應定期對(dui)無(wu)鹵素電(dian)(dian)子(zi)(zi)線(xian)(xian)路(lu)(lu)進(jin)行預防性耐壓測試，在無(wu)鹵電(dian)(dian)子(zi)(zi)線(xian)(xian)路(lu)(lu)絕緣降低不符合安全運(yun)行條件(jian)，應更(geng)換(huan)新電(dian)(dian)纜(lan)。
