不合格電線電纜的危害

電(dian)(dian)線電(dian)(dian)纜是(shi)用于傳輸(shu)電(dian)(dian)力、傳輸(shu)信息(xi)和實(shi)現電(dian)(dian)磁(ci)能量轉換(huan)的一大類電(dian)(dian)工(gong)產(chan)品。在抽查(cha)過程中，發現了大量的不合格(ge)產(chan)品，這(zhe)些(xie)劣質產(chan)品給電(dian)(dian)力系統正常運行埋下諸多隱患。

1、標(biao)志(zhi)(zhi)不合(he)格的電(dian)線電(dian)纜。標(biao)志(zhi)(zhi)是電(dian)線電(dian)纜使用識別產品(pin)基本信(xin)息的主要(yao)途徑，根據標(biao)準規定標(biao)志(zhi)(zhi)的主要(yao)內(nei)容是：產品(pin)型(xing)號(hao)、規格、標(biao)準號(hao)、廠名、產地等在一(yi)定的標(biao)示間距內(nei)，當標(biao)志(zhi)(zhi)不合(he)格時，會(hui)造成(cheng)施(shi)工人員(yuan)識別錯誤，嚴重時會(hui)引發電(dian)氣事故。

2、結構尺(chi)寸不合格的(de)(de)電(dian)(dian)線(xian)(xian)電(dian)(dian)纜(lan)(lan)。結構尺(chi)寸的(de)(de)主要問(wen)題(ti)是(shi)護(hu)套厚度，絕(jue)緣厚度，當電(dian)(dian)纜(lan)(lan)的(de)(de)護(hu)套和絕(jue)緣厚度不達標時(shi)，致使電(dian)(dian)線(xian)(xian)電(dian)(dian)纜(lan)(lan)耐電(dian)(dian)氣(qi)強(qiang)度會嚴重降(jiang)低(di)，導(dao)致電(dian)(dian)線(xian)(xian)電(dian)(dian)纜(lan)(lan)的(de)(de)使用(yong)壽命縮短，嚴重時(shi)可導(dao)致電(dian)(dian)線(xian)(xian)電(dian)(dian)纜(lan)(lan)被(bei)擊穿，絕(jue)緣（護(hu)套）層起不到正常保護(hu)作用(yong)，從(cong)而發生電(dian)(dian)氣(qi)短路(lu)和火災等現象(xiang)。

3、護(hu)套式(shi)絕緣(yuan)老化前的抗(kang)(kang)張強(qiang)度(du)、伸長率合(he)格(ge)的電線電纜(lan)。絕緣(yuan)護(hu)套老化前的抗(kang)(kang)張強(qiang)度(du)、伸長率不(bu)合(he)格(ge)直接大大縮短電線電纜(lan)的工(gong)作用壽命，而且在施工(gong)或(huo)在長時間通(tong)電且溫度(du)較高的環境中(zhong)，極易出(chu)現絕緣(yuan)體斷(duan)裂(lie)，致使(shi)帶(dai)電導(dao)體裸露，發生(sheng)(sheng)能觸電式(shi)短路危險。其不(bu)合(he)格(ge)的主要原因是使(shi)用了再(zai)生(sheng)(sheng)料生(sheng)(sheng)產，以(yi)降(jiang)低產品(pin)成本(ben)，二(er)是不(bu)具備(bei)生(sheng)(sheng)產資格(ge)小型(xing)企業。

4、導(dao)體(ti)(ti)(ti)電(dian)阻(zu)不(bu)合格的(de)(de)(de)(de)(de)電(dian)線。導(dao)體(ti)(ti)(ti)電(dian)阻(zu)主(zhu)要(yao)是考核電(dian)線電(dian)纜的(de)(de)(de)(de)(de)導(dao)體(ti)(ti)(ti)材料以及截面是否符合的(de)(de)(de)(de)(de)重(zhong)要(yao)指標。當導(dao)體(ti)(ti)(ti)電(dian)阻(zu)超標時(shi)，就增大(da)了電(dian)流(liu)在線路上通過時(shi)的(de)(de)(de)(de)(de)損(sun)耗，加劇了電(dian)線電(dian)纜的(de)(de)(de)(de)(de)發熱。導(dao)體(ti)(ti)(ti)電(dian)阻(zu)不(bu)合格的(de)(de)(de)(de)(de)原因，主(zhu)要(yao)進企業為了降(jiang)低成本(ben)，將(jiang)占(zhan)原材料成本(ben)80%的(de)(de)(de)(de)(de)銅(tong)材縮水，要(yao)么(me)降(jiang)低導(dao)體(ti)(ti)(ti)的(de)(de)(de)(de)(de)截面積，要(yao)么(me)使(shi)(shi)用含雜質過高的(de)(de)(de)(de)(de)再生銅(tong)，這樣致使(shi)(shi)電(dian)線電(dian)纜的(de)(de)(de)(de)(de)導(dao)體(ti)(ti)(ti)電(dian)阻(zu)嚴重(zhong)超標，在使(shi)(shi)用過程中(zhong)除易引(yin)發火災，還會加速包覆在電(dian)線外的(de)(de)(de)(de)(de)絕緣層的(de)(de)(de)(de)(de)老化。

在購買電(dian)線電(dian)纜的過程中，消費者應注意以下(xia)幾(ji)個事

第一、要觀(guan)察(cha)電線(xian)的(de)外觀(guan)。合格產品的(de)絕緣（護套(tao)）層柔(rou)軟、有韌性和伸縮性、表面層緊密、光滑、無(wu)粗糙感。如(ru)果包裹電線(xian)的(de)塑料(liao)很容易被剝去，則存在塑料(liao)強度不夠的(de)問題。

第(di)二、要看電線的(de)截面。合格產品的(de)銅芯或鋁(lv)芯表(biao)面應該具(ju)有金屬(shu)光澤，表(biao)面發(fa)黑的(de)銅或表(biao)面發(fa)白的(de)鋁(lv)說明(ming)已被氧(yang)化。

第三、在購買電(dian)線時應注意查看質量(liang)合格證書。如果電(dian)線的質量(liang)合格，那(nei)么其(qi)電(dian)線質量(liang)應該也受(shou)過檢驗，不會有太大的問題。
