不合格電(dian)線電(dian)纜(lan)的危害(hai)

電線電纜(lan)是用于傳(chuan)輸(shu)電力、傳(chuan)輸(shu)信息和實現(xian)(xian)電磁能量轉(zhuan)換的一大類電工產(chan)品。在(zai)抽查過程中(zhong)，發現(xian)(xian)了大量的不合格產(chan)品，這些劣質產(chan)品給電力系統正常運行埋下(xia)諸多隱患。

1、標(biao)(biao)志(zhi)(zhi)不合格(ge)的(de)電(dian)(dian)線電(dian)(dian)纜。標(biao)(biao)志(zhi)(zhi)是電(dian)(dian)線電(dian)(dian)纜使用(yong)識別產(chan)(chan)品基本信息的(de)主要(yao)途徑，根據標(biao)(biao)準規(gui)定標(biao)(biao)志(zhi)(zhi)的(de)主要(yao)內容是：產(chan)(chan)品型號(hao)、規(gui)格(ge)、標(biao)(biao)準號(hao)、廠名(ming)、產(chan)(chan)地(di)等在一定的(de)標(biao)(biao)示間距內，當(dang)標(biao)(biao)志(zhi)(zhi)不合格(ge)時(shi)，會(hui)造成施工人員識別錯誤，嚴重時(shi)會(hui)引發電(dian)(dian)氣事故。

2、結(jie)構尺寸不合格的電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)。結(jie)構尺寸的主要問(wen)題是護(hu)套厚(hou)度，絕(jue)(jue)緣厚(hou)度，當電(dian)(dian)(dian)纜(lan)的護(hu)套和絕(jue)(jue)緣厚(hou)度不達(da)標(biao)時(shi)，致使電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)耐電(dian)(dian)(dian)氣強度會嚴(yan)重(zhong)降低，導(dao)致電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)的使用壽命(ming)縮短，嚴(yan)重(zhong)時(shi)可導(dao)致電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)被擊穿，絕(jue)(jue)緣（護(hu)套）層起不到正常保(bao)護(hu)作用，從而發生電(dian)(dian)(dian)氣短路和火災等現象。

3、護(hu)套(tao)式絕緣老化前的(de)抗(kang)張強度(du)、伸(shen)長(chang)率合格的(de)電(dian)線電(dian)纜。絕緣護(hu)套(tao)老化前的(de)抗(kang)張強度(du)、伸(shen)長(chang)率不(bu)合格直接大大縮(suo)短電(dian)線電(dian)纜的(de)工作(zuo)用(yong)(yong)壽命，而且在(zai)施工或在(zai)長(chang)時間通電(dian)且溫度(du)較高的(de)環境中，極易出(chu)現(xian)絕緣體斷裂(lie)，致使帶(dai)電(dian)導體裸露，發生能觸(chu)電(dian)式短路危險。其(qi)不(bu)合格的(de)主要原因是使用(yong)(yong)了再生料生產，以降(jiang)低產品成本，二是不(bu)具備(bei)生產資(zi)格小型企業(ye)。

4、導(dao)體(ti)(ti)電(dian)(dian)(dian)阻(zu)(zu)(zu)不合(he)格的(de)(de)電(dian)(dian)(dian)線(xian)。導(dao)體(ti)(ti)電(dian)(dian)(dian)阻(zu)(zu)(zu)主要(yao)(yao)是(shi)考核電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)的(de)(de)導(dao)體(ti)(ti)材料以(yi)及截(jie)面(mian)是(shi)否(fou)符合(he)的(de)(de)重(zhong)(zhong)要(yao)(yao)指標。當導(dao)體(ti)(ti)電(dian)(dian)(dian)阻(zu)(zu)(zu)超標時(shi)，就增大了(le)電(dian)(dian)(dian)流在(zai)(zai)線(xian)路上(shang)通過時(shi)的(de)(de)損耗，加(jia)劇了(le)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)的(de)(de)發(fa)熱(re)。導(dao)體(ti)(ti)電(dian)(dian)(dian)阻(zu)(zu)(zu)不合(he)格的(de)(de)原因，主要(yao)(yao)進企業為了(le)降低成(cheng)(cheng)本，將占原材料成(cheng)(cheng)本80%的(de)(de)銅材縮(suo)水(shui)，要(yao)(yao)么(me)降低導(dao)體(ti)(ti)的(de)(de)截(jie)面(mian)積，要(yao)(yao)么(me)使(shi)用含雜(za)質(zhi)過高的(de)(de)再生(sheng)銅，這樣(yang)致使(shi)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)的(de)(de)導(dao)體(ti)(ti)電(dian)(dian)(dian)阻(zu)(zu)(zu)嚴重(zhong)(zhong)超標，在(zai)(zai)使(shi)用過程中除易引(yin)發(fa)火災(zai)，還會加(jia)速包覆在(zai)(zai)電(dian)(dian)(dian)線(xian)外的(de)(de)絕緣層的(de)(de)老(lao)化(hua)。

在購買電(dian)線電(dian)纜的過程中，消費者應注(zhu)意(yi)以下幾個事

第一、要觀察電(dian)線的外(wai)觀。合格(ge)產品的絕(jue)緣（護套(tao)）層柔軟、有(you)韌性和(he)伸縮性、表(biao)面層緊密、光滑、無(wu)粗(cu)糙感。如果包裹電(dian)線的塑料(liao)很容易被剝去(qu)，則存在塑料(liao)強度不夠的問(wen)題。

第二(er)、要看電(dian)線的(de)(de)截面(mian)。合格產品的(de)(de)銅芯(xin)或鋁芯(xin)表(biao)(biao)面(mian)應(ying)該具有金屬光(guang)澤，表(biao)(biao)面(mian)發黑的(de)(de)銅或表(biao)(biao)面(mian)發白的(de)(de)鋁說(shuo)明已被氧化。

第三、在購買電線(xian)時應注意查看質(zhi)(zhi)量合格證書。如果電線(xian)的(de)質(zhi)(zhi)量合格，那(nei)么(me)其電線(xian)質(zhi)(zhi)量應該也受過(guo)檢(jian)驗，不會(hui)有太大的(de)問題。
