電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)(lan)斷(duan)(duan)點的(de)(de)(de)(de)判斷(duan)(duan)技巧(qiao)具體方(fang)法：把有(you)斷(duan)(duan)點的(de)(de)(de)(de)電(dian)(dian)(dian)線(xian)(xian)（電(dian)(dian)(dian)纜(lan)(lan)）一(yi)(yi)端(duan)(duan)接(jie)(jie)在220V市(shi)電(dian)(dian)(dian)的(de)(de)(de)(de)火線(xian)(xian)上，另一(yi)(yi)端(duan)(duan)懸空。將(jiang)數字萬用表(biao)(biao)拔至AC2V擋(dang)，從電(dian)(dian)(dian)線(xian)(xian)（電(dian)(dian)(dian)纜(lan)(lan)）的(de)(de)(de)(de)火線(xian)(xian)接(jie)(jie)入(ru)端(duan)(duan)開始，用一(yi)(yi)只手捏住黑表(biao)(biao)筆的(de)(de)(de)(de)筆尖，另一(yi)(yi)只手將(jiang)紅(hong)(hong)表(biao)(biao)筆沿導線(xian)(xian)的(de)(de)(de)(de)絕(jue)緣皮慢慢移動，此時(shi)顯示屏(ping)顯示的(de)(de)(de)(de)電(dian)(dian)(dian)壓值大(da)約(yue)(yue)為0。445V（DT890D型表(biao)(biao)所測）左右。當紅(hong)(hong)表(biao)(biao)筆移動到某處時(shi)，顯示屏(ping)顯示的(de)(de)(de)(de)電(dian)(dian)(dian)壓突(tu)然下降到0。0幾伏(fu)（大(da)約(yue)(yue)是(shi)原來電(dian)(dian)(dian)壓的(de)(de)(de)(de)十分(fen)之一(yi)(yi)），從該位置向(xiang)前（火線(xian)(xian)接(jie)(jie)入(ru)端(duan)(duan)）的(de)(de)(de)(de)大(da)約(yue)(yue)15cm處即是(shi)電(dian)(dian)(dian)線(xian)(xian)（電(dian)(dian)(dian)纜(lan)(lan)）斷(duan)(duan)點所在。

遇到電(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)纜(lan)進(jin)水(shui)(shui)你是(shi)怎么解決的(de)(de)？一、電(dian)(dian)(dian)(dian)(dian)纜(lan)里(li)(li)面有水(shui)(shui)的(de)(de)危(wei)害(hai)。一般(ban)而言，電(dian)(dian)(dian)(dian)(dian)纜(lan)進(jin)水(shui)(shui)后，在電(dian)(dian)(dian)(dian)(dian)磁(ci)場(chang)的(de)(de)作(zuo)用(yong)下會發(fa)生“水(shui)(shui)樹(shu)老化”現象(xiang)，電(dian)(dian)(dian)(dian)(dian)纜(lan)損壞(huai)只會是(shi)時(shi)間問題，終會導致電(dian)(dian)(dian)(dian)(dian)纜(lan)擊(ji)穿。二(er)、電(dian)(dian)(dian)(dian)(dian)纜(lan)里(li)(li)面有水(shui)(shui)的(de)(de)原(yuan)因。1，電(dian)(dian)(dian)(dian)(dian)纜(lan)敷(fu)設保存時(shi)，兩端電(dian)(dian)(dian)(dian)(dian)纜(lan)頭(tou)并沒有進(jin)行密(mi)封(feng)處理或者密(mi)封(feng)性不好(hao)，水(shui)(shui)汽(qi)滲(shen)入(ru)電(dian)(dian)(dian)(dian)(dian)纜(lan)內部。2，電(dian)(dian)(dian)(dian)(dian)纜(lan)敷(fu)設過(guo)程中(zhong)，電(dian)(dian)(dian)(dian)(dian)纜(lan)頭(tou)密(mi)封(feng)不好(hao)且浸泡在水(shui)(shui)中(zhong)，或者在穿管敷(fu)設時(shi)，電(dian)(dian)(dian)(dian)(dian)纜(lan)外(wai)絕緣皮，水(shui)(shui)滲(shen)入(ru)電(dian)(dian)(dian)(dian)(dian)纜(lan)。3，電(dian)(dian)(dian)(dian)(dian)纜(lan)敷(fu)設完成后，兩端的(de)(de)電(dian)(dian)(dian)(dian)(dian)纜(lan)頭(tou)沒有及時(shi)制作(zuo)，長(chang)期暴露在空氣中(zhong)或者潮濕環境中(zhong)。4，電(dian)(dian)(dian)(dian)(dian)纜(lan)供電(dian)(dian)(dian)(dian)(dian)運行過(guo)程中(zhong)發(fa)生過(guo)局部電(dian)(dian)(dian)(dian)(dian)纜(lan)擊(ji)穿，水(shui)(shui)滲(shen)入(ru)電(dian)(dian)(dian)(dian)(dian)纜(lan)。

環保(bao)(bao)型(xing)電(dian)纜(lan)相較(jiao)于(yu)普通電(dian)纜(lan)具有(you)以下這(zhe)些方面的(de)優(you)勢：個(ge)就是具有(you)較(jiao)高的(de)阻(zu)燃性(xing)(xing)，綠寶電(dian)線電(dian)纜(lan)價格，我們都知(zhi)道(dao)，電(dian)纜(lan)的(de)阻(zu)燃性(xing)(xing)能是非常重(zhong)要(yao)的(de)，完全(quan)確保(bao)(bao)安全(quan)防火要(yao)求的(de)電(dian)纜(lan)，電(dian)纜(lan)不(bu)容燒(shao)(shao)起火，并能阻(zu)止火焰的(de)擴大(da)。第2個(ge)是無異味和(he)腐(fu)蝕性(xing)(xing)氣(qi)味，不(bu)含有(you)鹽酸和(he)其他的(de)有(you)毒(du)氣(qi)體，對環境無污染生(sheng)產的(de)新的(de)環保(bao)(bao)型(xing)涂層的(de)電(dian)線電(dian)纜(lan)料，使用過(guo)程和(he)燃燒(shao)(shao)中不(bu)會產生(sheng)或是非常少(shao)排(pai)放酸性(xing)(xing)氣(qi)體，保(bao)(bao)證人員的(de)安全(quan)和(he)減少(shao)設備儀(yi)器損(sun)壞等環保(bao)(bao)的(de)特點。
