不合格電(dian)線電(dian)纜的危害

電(dian)(dian)線電(dian)(dian)纜是用于(yu)傳(chuan)輸電(dian)(dian)力、傳(chuan)輸信息和實現電(dian)(dian)磁能量轉換的(de)一大(da)類電(dian)(dian)工(gong)產品。在抽查過程中(zhong)，發現了大(da)量的(de)不合格產品，這些劣質(zhi)產品給電(dian)(dian)力系統正常運行埋下諸多(duo)隱患。

1、標(biao)志(zhi)(zhi)不(bu)合格的(de)電(dian)線電(dian)纜(lan)。標(biao)志(zhi)(zhi)是電(dian)線電(dian)纜(lan)使用(yong)識(shi)別產(chan)品(pin)基本信息的(de)主(zhu)要途徑(jing)，根據標(biao)準規定標(biao)志(zhi)(zhi)的(de)主(zhu)要內(nei)容是：產(chan)品(pin)型號(hao)、規格、標(biao)準號(hao)、廠名、產(chan)地(di)等在(zai)一定的(de)標(biao)示間距內(nei)，當標(biao)志(zhi)(zhi)不(bu)合格時，會造成(cheng)施工人(ren)員(yuan)識(shi)別錯(cuo)誤，嚴重時會引發(fa)電(dian)氣事故。

2、結構(gou)尺寸不(bu)(bu)合格的電(dian)線電(dian)纜(lan)。結構(gou)尺寸的主要問(wen)題是護(hu)套(tao)厚(hou)度(du)，絕(jue)緣(yuan)(yuan)厚(hou)度(du)，當(dang)電(dian)纜(lan)的護(hu)套(tao)和(he)絕(jue)緣(yuan)(yuan)厚(hou)度(du)不(bu)(bu)達標時，致(zhi)使電(dian)線電(dian)纜(lan)耐電(dian)氣強(qiang)度(du)會(hui)嚴(yan)重降(jiang)低，導致(zhi)電(dian)線電(dian)纜(lan)的使用壽命縮短，嚴(yan)重時可(ke)導致(zhi)電(dian)線電(dian)纜(lan)被擊(ji)穿，絕(jue)緣(yuan)(yuan)（護(hu)套(tao)）層起不(bu)(bu)到正常(chang)保護(hu)作用，從而發生電(dian)氣短路和(he)火災等現(xian)象。

3、護套式絕(jue)緣(yuan)老(lao)化(hua)前(qian)的抗張強(qiang)度(du)、伸(shen)長(chang)率合格的電(dian)線電(dian)纜(lan)。絕(jue)緣(yuan)護套老(lao)化(hua)前(qian)的抗張強(qiang)度(du)、伸(shen)長(chang)率不合格直接大(da)大(da)縮短(duan)電(dian)線電(dian)纜(lan)的工作用壽命，而且(qie)在施工或在長(chang)時間通電(dian)且(qie)溫(wen)度(du)較高的環境中，極(ji)易出現絕(jue)緣(yuan)體斷(duan)裂，致(zhi)使帶(dai)電(dian)導體裸露，發(fa)生能觸電(dian)式短(duan)路危(wei)險。其不合格的主要原因是使用了再生料(liao)生產(chan)，以(yi)降低產(chan)品成本(ben)，二是不具備(bei)生產(chan)資格小(xiao)型企業。

4、導(dao)體(ti)電(dian)(dian)(dian)阻(zu)不合(he)格(ge)的(de)(de)(de)(de)電(dian)(dian)(dian)線。導(dao)體(ti)電(dian)(dian)(dian)阻(zu)主(zhu)(zhu)要(yao)是考核電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)的(de)(de)(de)(de)導(dao)體(ti)材(cai)料以(yi)及截面是否符(fu)合(he)的(de)(de)(de)(de)重要(yao)指(zhi)標。當導(dao)體(ti)電(dian)(dian)(dian)阻(zu)超(chao)標時，就增大了電(dian)(dian)(dian)流在線路上通過(guo)時的(de)(de)(de)(de)損(sun)耗，加劇(ju)了電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)的(de)(de)(de)(de)發熱。導(dao)體(ti)電(dian)(dian)(dian)阻(zu)不合(he)格(ge)的(de)(de)(de)(de)原(yuan)因，主(zhu)(zhu)要(yao)進企業(ye)為了降低(di)成(cheng)(cheng)本(ben)，將占原(yuan)材(cai)料成(cheng)(cheng)本(ben)80%的(de)(de)(de)(de)銅材(cai)縮(suo)水，要(yao)么(me)降低(di)導(dao)體(ti)的(de)(de)(de)(de)截面積，要(yao)么(me)使(shi)用含雜質(zhi)過(guo)高的(de)(de)(de)(de)再生銅，這(zhe)樣致使(shi)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)的(de)(de)(de)(de)導(dao)體(ti)電(dian)(dian)(dian)阻(zu)嚴重超(chao)標，在使(shi)用過(guo)程中除易引發火災，還(huan)會加速包覆在電(dian)(dian)(dian)線外的(de)(de)(de)(de)絕緣層的(de)(de)(de)(de)老化。

在購(gou)買電(dian)線電(dian)纜的過程中，消費者應注(zhu)意以下幾(ji)個事

第一(yi)、要(yao)觀察電線的外觀。合格產品的絕(jue)緣（護套(tao)）層柔軟、有韌性(xing)和伸縮性(xing)、表(biao)面(mian)層緊密、光(guang)滑(hua)、無(wu)粗糙(cao)感。如果包裹電線的塑料很(hen)容(rong)易(yi)被剝(bo)去，則存在(zai)塑料強度不夠的問題(ti)。

第二、要(yao)看電線的截面(mian)。合(he)格產品的銅(tong)芯(xin)或(huo)鋁(lv)芯(xin)表面(mian)應該(gai)具(ju)有金屬光澤，表面(mian)發(fa)黑的銅(tong)或(huo)表面(mian)發(fa)白的鋁(lv)說明已被(bei)氧化(hua)。

第三、在購買電線(xian)時應注(zhu)意查看(kan)質量(liang)合(he)格(ge)證(zheng)書。如果(guo)電線(xian)的質量(liang)合(he)格(ge)，那么其(qi)電線(xian)質量(liang)應該(gai)也受過檢驗(yan)，不會有太大的問題。
