絕緣受潮(chao)：由于(yu)(yu)無鹵(lu)(lu)(lu)電(dian)(dian)(dian)子(zi)線(xian)路(lu)(lu)(lu)施工(gong)工(gong)藝差，濕(shi)氣(qi)侵入電(dian)(dian)(dian)子(zi)線(xian)路(lu)(lu)(lu)內(nei)(nei)部(bu)，或無鹵(lu)(lu)(lu)電(dian)(dian)(dian)子(zi)線(xian)路(lu)(lu)(lu)內(nei)(nei)保護層(ceng)損壞，濕(shi)氣(qi)進(jin)入無鹵(lu)(lu)(lu)電(dian)(dian)(dian)子(zi)線(xian)路(lu)(lu)(lu)；鉛包電(dian)(dian)(dian)纜(lan)敷(fu)設(she)在(zai)震源周圍，因(yin)(yin)長期振動而(er)疲勞開裂，無鹵(lu)(lu)(lu)電(dian)(dian)(dian)子(zi)線(xian)路(lu)(lu)(lu)的外皮被腐蝕(shi)并漂浮，由于(yu)(yu)制(zhi)造(zao)質量不好，鉛包上(shang)有小孔或裂紋；鑒于(yu)(yu)這(zhe)些現象，應加(jia)強無鹵(lu)(lu)(lu)電(dian)(dian)(dian)子(zi)線(xian)路(lu)(lu)(lu)外層(ceng)的維護，并按期在(zai)外保護層(ceng)上(shang)涂一層(ceng)瀝(li)青(qing)。過(guo)電(dian)(dian)(dian)壓(ya)(ya)(ya)：無鹵(lu)(lu)(lu)電(dian)(dian)(dian)子(zi)線(xian)路(lu)(lu)(lu)絕緣層(ceng)因(yin)(yin)大(da)氣(qi)過(guo)電(dian)(dian)(dian)壓(ya)(ya)(ya)或內(nei)(nei)部(bu)過(guo)電(dian)(dian)(dian)壓(ya)(ya)(ya)而(er)擊穿(chuan)，特別是系統內(nei)(nei)部(bu)過(guo)電(dian)(dian)(dian)壓(ya)(ya)(ya)會(hui)導致多根(gen)電(dian)(dian)(dian)纜(lan)同時擊穿(chuan)，在(zai)這(zhe)方面，應安裝避雷器(qi)。

絕(jue)緣老化(hua)：在無鹵(lu)電(dian)子線(xian)(xian)路(lu)的長(chang)期(qi)運行過(guo)(guo)程中(zhong)，由于散熱不良或過(guo)(guo)載，絕(jue)緣材料的電(dian)氣和(he)機械功(gong)能變差，絕(jue)緣層變脆或斷(duan)裂，如(ru)果是這(zhe)種情況，應定期(qi)對無鹵(lu)素電(dian)子線(xian)(xian)路(lu)進行預(yu)防性耐壓測試，在無鹵(lu)電(dian)子線(xian)(xian)路(lu)絕(jue)緣降低不符合安(an)全運行條件，應更換(huan)新電(dian)纜。
