在(zai)電(dian)(dian)(dian)纜(lan)(lan)制造過(guo)程(cheng)中，由外面侵入的(de)極微(wei)量(liang)的(de)水(shui)(shui)(shui)分(fen)在(zai)電(dian)(dian)(dian)纜(lan)(lan)絕緣層(ceng)(ceng)中是(shi)均勻(yun)分(fen)布的(de)，但(dan)電(dian)(dian)(dian)纜(lan)(lan)投(tou)入使用后在(zai)電(dian)(dian)(dian)場的(de)作用下(xia)，受到不均勻(yun)電(dian)(dian)(dian)場的(de)吸引(yin)，產(chan)生極化遷移，逐漸積累(lei)而(er)產(chan)生局部(bu)過(guo)飽和(he)(he)狀(zhuang)態形成(cheng)水(shui)(shui)(shui)樹(shu)。電(dian)(dian)(dian)纜(lan)(lan)的(de)絕緣層(ceng)(ceng)中只要同時存在(zai)水(shui)(shui)(shui)和(he)(he)電(dian)(dian)(dian)場就會(hui)產(chan)生水(shui)(shui)(shui)樹(shu)。水(shui)(shui)(shui)樹(shu)是(shi)直(zhi)徑在(zai)０．１微(wei)米(mi)到幾微(wei)米(mi)充滿(man)水(shui)(shui)(shui)的(de)空隙集合。水(shui)(shui)(shui)樹(shu)和(he)(he)環境(jing)(jing)濕度也有(you)關，交(jiao)聯聚(ju)乙烯電(dian)(dian)(dian)纜(lan)(lan)在(zai)６５％以(yi)上的(de)濕度環境(jing)(jing)中通電(dian)(dian)(dian)就可以(yi)產(chan)生水(shui)(shui)(shui)樹(shu)。水(shui)(shui)(shui)樹(shu)的(de)存在(zai)直(zhi)接影響到電(dian)(dian)(dian)纜(lan)(lan)的(de)壽命。為(wei)了降低水(shui)(shui)(shui)樹(shu)的(de)增長速度，在(zai)地下(xia)水(shui)(shui)(shui)位較高(gao)及多雨(yu)(yu)的(de)地區，高(gao)溫電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)(lan)廠，不宜采取埋地敷設；在(zai)南方地區黃梅季節(jie)電(dian)(dian)(dian)纜(lan)(lan)溝內容易結露，因此要有(you)通內措(cuo)施(shi)(shi)；電(dian)(dian)(dian)纜(lan)(lan)的(de)入口處(chu)應有(you)堵(du)水(shui)(shui)(shui)措(cuo)施(shi)(shi)，避免雨(yu)(yu)水(shui)(shui)(shui)流入電(dian)(dian)(dian)纜(lan)(lan)。

電(dian)纜(lan)(lan)(lan)(lan)如何(he)防(fang)水(shui)？1、電(dian)纜(lan)(lan)(lan)(lan)接(jie)(jie)頭(tou)(tou)應密封，切斷電(dian)纜(lan)(lan)(lan)(lan)的(de)結束(shu)，堆放或(huo)鋪(pu)設應當與塑料密封，防(fang)止水(shui)分滲透。2、電(dian)線(xian)和(he)電(dian)纜(lan)(lan)(lan)(lan)敷設后應及時(shi)在生產。3、購買電(dian)纜(lan)(lan)(lan)(lan)：必須選擇質(zhi)(zhi)量(liang)制造商(shang)、電(dian)纜(lan)(lan)(lan)(lan)專賣(mai)店：因為雜質(zhi)(zhi)的(de)絕(jue)緣、氣孔發生水(shui)樹(shu)的(de)起點，和(he)電(dian)纜(lan)(lan)(lan)(lan)質(zhi)(zhi)量(liang)是(shi)非常重要(yao)(yao)的(de)防(fang)止水(shui)樹(shu)老(lao)化。4、加強電(dian)纜(lan)(lan)(lan)(lan)頭(tou)(tou)生產過程管理：一(yi)旦電(dian)纜(lan)(lan)(lan)(lan)進水(shui)里(li)，是(shi)早出現(xian)擊(ji)穿現(xian)象往(wang)往(wang)是(shi)有線(xian)頭(tou)(tou)，因此鋼絲生產井，可以延(yan)長電(dian)纜(lan)(lan)(lan)(lan)的(de)一(yi)生。5、寒冷(leng)的(de)電(dian)纜(lan)(lan)(lan)(lan)頭(tou)(tou)：3m的(de)冷(leng)收縮硅橡膠電(dian)纜(lan)(lan)(lan)(lan)配件，生產簡單(dan)方便(bian)，不(bu)用燈，不(bu)需(xu)要(yao)(yao)焊接(jie)(jie)。6、完成(cheng)后的(de)電(dian)纜(lan)(lan)(lan)(lan)測(ce)試電(dian)纜(lan)(lan)(lan)(lan)頭(tou)(tou)生產：投產前高壓直流泄(xie)漏(lou)試驗，試驗后測(ce)試變電(dian)站電(dian)線(xian)電(dian)纜(lan)(lan)(lan)(lan)，其他電(dian)纜(lan)(lan)(lan)(lan)不(bu)測(ce)試。
