絕緣(yuan)受(shou)潮：由于(yu)無(wu)鹵電(dian)(dian)(dian)(dian)子(zi)線(xian)(xian)路(lu)(lu)(lu)施工工藝差，濕(shi)氣(qi)侵入(ru)電(dian)(dian)(dian)(dian)子(zi)線(xian)(xian)路(lu)(lu)(lu)內部，或(huo)無(wu)鹵電(dian)(dian)(dian)(dian)子(zi)線(xian)(xian)路(lu)(lu)(lu)內保護層(ceng)損(sun)壞，濕(shi)氣(qi)進入(ru)無(wu)鹵電(dian)(dian)(dian)(dian)子(zi)線(xian)(xian)路(lu)(lu)(lu)；鉛包電(dian)(dian)(dian)(dian)纜(lan)敷設在(zai)(zai)震源周(zhou)圍(wei)，因長(chang)期振動而疲勞開裂(lie)，無(wu)鹵電(dian)(dian)(dian)(dian)子(zi)線(xian)(xian)路(lu)(lu)(lu)的外皮被腐(fu)蝕(shi)并漂(piao)浮，由于(yu)制(zhi)造質量不好，鉛包上(shang)有小(xiao)孔或(huo)裂(lie)紋；鑒于(yu)這些現(xian)象(xiang)，應(ying)(ying)加(jia)強(qiang)無(wu)鹵電(dian)(dian)(dian)(dian)子(zi)線(xian)(xian)路(lu)(lu)(lu)外層(ceng)的維(wei)護，并按(an)期在(zai)(zai)外保護層(ceng)上(shang)涂一層(ceng)瀝青。過電(dian)(dian)(dian)(dian)壓：無(wu)鹵電(dian)(dian)(dian)(dian)子(zi)線(xian)(xian)路(lu)(lu)(lu)絕緣(yuan)層(ceng)因大氣(qi)過電(dian)(dian)(dian)(dian)壓或(huo)內部過電(dian)(dian)(dian)(dian)壓而擊穿，特別是系統內部過電(dian)(dian)(dian)(dian)壓會(hui)導致多根電(dian)(dian)(dian)(dian)纜(lan)同時(shi)擊穿，在(zai)(zai)這方面，應(ying)(ying)安裝避雷器(qi)。

絕(jue)(jue)緣老化：在無(wu)鹵電子(zi)線(xian)路的(de)長期運行過程(cheng)中，由于散熱不良或過載(zai)，絕(jue)(jue)緣材料(liao)的(de)電氣(qi)和機械功(gong)能變差，絕(jue)(jue)緣層(ceng)變脆或斷裂，如果是這種(zhong)情況(kuang)，應定期對(dui)無(wu)鹵素電子(zi)線(xian)路進行預(yu)防(fang)性耐壓(ya)測(ce)試，在無(wu)鹵電子(zi)線(xian)路絕(jue)(jue)緣降(jiang)低不符合安(an)全運行條件，應更換新電纜。
