不合格電線電纜的危害(hai)

電(dian)(dian)線(xian)電(dian)(dian)纜是用于傳(chuan)輸(shu)電(dian)(dian)力(li)、傳(chuan)輸(shu)信息和(he)實現電(dian)(dian)磁能量轉換的(de)一大(da)類電(dian)(dian)工產(chan)品。在抽查(cha)過程中，發現了大(da)量的(de)不合格產(chan)品，這(zhe)些劣質產(chan)品給電(dian)(dian)力(li)系統正常運行埋(mai)下諸多(duo)隱(yin)患。

1、標(biao)志不合(he)格(ge)的電(dian)(dian)線電(dian)(dian)纜。標(biao)志是電(dian)(dian)線電(dian)(dian)纜使用(yong)識別產品(pin)基本信息(xi)的主要途徑，根據標(biao)準(zhun)規定標(biao)志的主要內容是：產品(pin)型號、規格(ge)、標(biao)準(zhun)號、廠(chang)名、產地等在(zai)一定的標(biao)示間距內，當標(biao)志不合(he)格(ge)時，會造成施工人員識別錯誤，嚴重(zhong)時會引發電(dian)(dian)氣事故。

2、結構尺(chi)寸不(bu)合格(ge)的(de)(de)電(dian)(dian)線電(dian)(dian)纜(lan)。結構尺(chi)寸的(de)(de)主要問題是(shi)護(hu)套厚度(du)，絕緣厚度(du)，當電(dian)(dian)纜(lan)的(de)(de)護(hu)套和絕緣厚度(du)不(bu)達標時，致(zhi)使電(dian)(dian)線電(dian)(dian)纜(lan)耐電(dian)(dian)氣(qi)(qi)強度(du)會嚴(yan)重降低，導致(zhi)電(dian)(dian)線電(dian)(dian)纜(lan)的(de)(de)使用壽命縮短(duan)，嚴(yan)重時可導致(zhi)電(dian)(dian)線電(dian)(dian)纜(lan)被擊穿(chuan)，絕緣（護(hu)套）層起不(bu)到正常保護(hu)作(zuo)用，從(cong)而發(fa)生電(dian)(dian)氣(qi)(qi)短(duan)路和火(huo)災等現象。

3、護套式(shi)絕(jue)緣老化前的(de)(de)抗張(zhang)強(qiang)度(du)、伸長率合格的(de)(de)電(dian)(dian)線電(dian)(dian)纜。絕(jue)緣護套老化前的(de)(de)抗張(zhang)強(qiang)度(du)、伸長率不(bu)合格直接大(da)大(da)縮短電(dian)(dian)線電(dian)(dian)纜的(de)(de)工(gong)作(zuo)用(yong)壽命，而且在施工(gong)或在長時間(jian)通電(dian)(dian)且溫(wen)度(du)較(jiao)高的(de)(de)環(huan)境中，極易(yi)出現(xian)絕(jue)緣體斷(duan)裂，致使帶(dai)電(dian)(dian)導體裸露，發生能觸電(dian)(dian)式(shi)短路危(wei)險。其不(bu)合格的(de)(de)主要原因是使用(yong)了再生料(liao)生產(chan)，以降低產(chan)品成(cheng)本，二是不(bu)具備生產(chan)資(zi)格小型(xing)企業。

4、導(dao)(dao)(dao)(dao)體(ti)(ti)(ti)(ti)電(dian)(dian)阻(zu)(zu)不合(he)格的(de)(de)電(dian)(dian)線。導(dao)(dao)(dao)(dao)體(ti)(ti)(ti)(ti)電(dian)(dian)阻(zu)(zu)主(zhu)要是考核(he)電(dian)(dian)線電(dian)(dian)纜(lan)的(de)(de)導(dao)(dao)(dao)(dao)體(ti)(ti)(ti)(ti)材料以及截面是否符合(he)的(de)(de)重要指標。當導(dao)(dao)(dao)(dao)體(ti)(ti)(ti)(ti)電(dian)(dian)阻(zu)(zu)超(chao)標時，就(jiu)增大了電(dian)(dian)流在線路上(shang)通過(guo)(guo)(guo)時的(de)(de)損(sun)耗，加劇了電(dian)(dian)線電(dian)(dian)纜(lan)的(de)(de)發(fa)熱。導(dao)(dao)(dao)(dao)體(ti)(ti)(ti)(ti)電(dian)(dian)阻(zu)(zu)不合(he)格的(de)(de)原因(yin)，主(zhu)要進企業為了降(jiang)低成本，將占原材料成本80%的(de)(de)銅材縮水，要么降(jiang)低導(dao)(dao)(dao)(dao)體(ti)(ti)(ti)(ti)的(de)(de)截面積(ji)，要么使(shi)用含雜質過(guo)(guo)(guo)高的(de)(de)再生銅，這樣致(zhi)使(shi)電(dian)(dian)線電(dian)(dian)纜(lan)的(de)(de)導(dao)(dao)(dao)(dao)體(ti)(ti)(ti)(ti)電(dian)(dian)阻(zu)(zu)嚴重超(chao)標，在使(shi)用過(guo)(guo)(guo)程中(zhong)除易引(yin)發(fa)火災(zai)，還(huan)會(hui)加速包覆在電(dian)(dian)線外的(de)(de)絕緣層的(de)(de)老化。

在(zai)購買電(dian)線電(dian)纜的(de)過程中，消(xiao)費者應注意(yi)以(yi)下(xia)幾個事

第一、要觀(guan)察電線(xian)的外(wai)觀(guan)。合格(ge)產品的絕緣（護套）層柔軟、有韌性和伸(shen)縮性、表(biao)面層緊密、光(guang)滑、無(wu)粗糙感。如果(guo)包裹電線(xian)的塑料很容易被剝去，則存(cun)在(zai)塑料強度不夠的問題(ti)。

第二、要看電(dian)線的(de)(de)截面。合格產品的(de)(de)銅芯(xin)或鋁芯(xin)表面應該具有金屬光澤，表面發(fa)黑(hei)的(de)(de)銅或表面發(fa)白的(de)(de)鋁說(shuo)明已被氧化。

第三(san)、在購買(mai)電(dian)(dian)線時應注意查看(kan)質(zhi)量合(he)格證書。如果電(dian)(dian)線的質(zhi)量合(he)格，那么其電(dian)(dian)線質(zhi)量應該也受過檢驗，不會有太大的問題。
