不合格電線電纜的危害

電(dian)(dian)(dian)線電(dian)(dian)(dian)纜是(shi)用于傳輸電(dian)(dian)(dian)力(li)、傳輸信息和實現(xian)(xian)電(dian)(dian)(dian)磁能量(liang)轉換(huan)的(de)一大類電(dian)(dian)(dian)工產(chan)品。在抽查過程(cheng)中(zhong)，發現(xian)(xian)了大量(liang)的(de)不合格產(chan)品，這(zhe)些(xie)劣(lie)質產(chan)品給電(dian)(dian)(dian)力(li)系統(tong)正常運行埋下諸多(duo)隱(yin)患。

1、標(biao)(biao)志(zhi)不合(he)(he)格的(de)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜。標(biao)(biao)志(zhi)是電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜使用識別(bie)產品(pin)基本(ben)信(xin)息的(de)主(zhu)(zhu)要(yao)途(tu)徑，根(gen)據標(biao)(biao)準規(gui)定標(biao)(biao)志(zhi)的(de)主(zhu)(zhu)要(yao)內(nei)(nei)容是：產品(pin)型(xing)號、規(gui)格、標(biao)(biao)準號、廠名、產地(di)等在一定的(de)標(biao)(biao)示(shi)間距內(nei)(nei)，當標(biao)(biao)志(zhi)不合(he)(he)格時(shi)，會造成施工人員識別(bie)錯誤(wu)，嚴重時(shi)會引發(fa)電(dian)(dian)(dian)氣事故。

2、結(jie)構尺(chi)寸不(bu)合格的電(dian)線電(dian)纜(lan)(lan)。結(jie)構尺(chi)寸的主要問題是護(hu)套(tao)厚度，絕(jue)(jue)緣(yuan)厚度，當(dang)電(dian)纜(lan)(lan)的護(hu)套(tao)和(he)絕(jue)(jue)緣(yuan)厚度不(bu)達標時，致(zhi)使電(dian)線電(dian)纜(lan)(lan)耐電(dian)氣強度會嚴重(zhong)降(jiang)低，導致(zhi)電(dian)線電(dian)纜(lan)(lan)的使用壽(shou)命縮(suo)短，嚴重(zhong)時可(ke)導致(zhi)電(dian)線電(dian)纜(lan)(lan)被(bei)擊穿，絕(jue)(jue)緣(yuan)（護(hu)套(tao)）層起不(bu)到正常保(bao)護(hu)作用，從而發(fa)生電(dian)氣短路和(he)火災(zai)等現象(xiang)。

3、護套式絕(jue)緣老(lao)化(hua)前的(de)(de)抗(kang)張強度(du)(du)、伸長(chang)率合(he)格(ge)的(de)(de)電(dian)線(xian)電(dian)纜。絕(jue)緣護套老(lao)化(hua)前的(de)(de)抗(kang)張強度(du)(du)、伸長(chang)率不合(he)格(ge)直接大大縮(suo)短電(dian)線(xian)電(dian)纜的(de)(de)工作用壽命，而且在施工或在長(chang)時間通電(dian)且溫度(du)(du)較高的(de)(de)環境中，極易出現絕(jue)緣體斷裂，致使帶電(dian)導體裸露，發生能觸(chu)電(dian)式短路危險(xian)。其不合(he)格(ge)的(de)(de)主要原因是使用了再生料生產，以(yi)降低產品成本(ben)，二是不具(ju)備生產資格(ge)小(xiao)型企(qi)業(ye)。

4、導(dao)(dao)(dao)體(ti)電(dian)(dian)(dian)(dian)阻不合(he)格的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)線(xian)(xian)。導(dao)(dao)(dao)體(ti)電(dian)(dian)(dian)(dian)阻主要(yao)是(shi)考核電(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)纜的(de)(de)(de)(de)導(dao)(dao)(dao)體(ti)材(cai)料(liao)以及截(jie)面(mian)(mian)是(shi)否符合(he)的(de)(de)(de)(de)重要(yao)指標。當導(dao)(dao)(dao)體(ti)電(dian)(dian)(dian)(dian)阻超標時，就(jiu)增大了電(dian)(dian)(dian)(dian)流在線(xian)(xian)路上通過(guo)時的(de)(de)(de)(de)損耗(hao)，加劇了電(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)纜的(de)(de)(de)(de)發(fa)熱(re)。導(dao)(dao)(dao)體(ti)電(dian)(dian)(dian)(dian)阻不合(he)格的(de)(de)(de)(de)原因，主要(yao)進企業為了降(jiang)(jiang)低(di)成(cheng)本(ben)，將占原材(cai)料(liao)成(cheng)本(ben)80%的(de)(de)(de)(de)銅材(cai)縮水，要(yao)么降(jiang)(jiang)低(di)導(dao)(dao)(dao)體(ti)的(de)(de)(de)(de)截(jie)面(mian)(mian)積，要(yao)么使用(yong)含雜質過(guo)高的(de)(de)(de)(de)再生銅，這樣致(zhi)使電(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)纜的(de)(de)(de)(de)導(dao)(dao)(dao)體(ti)電(dian)(dian)(dian)(dian)阻嚴重超標，在使用(yong)過(guo)程(cheng)中除易引發(fa)火災，還(huan)會(hui)加速包覆在電(dian)(dian)(dian)(dian)線(xian)(xian)外(wai)的(de)(de)(de)(de)絕緣層的(de)(de)(de)(de)老化。

在購(gou)買電線(xian)電纜的過(guo)程中(zhong)，消費者應(ying)注意以下(xia)幾(ji)個事

第一、要(yao)觀察(cha)電(dian)線的(de)外觀。合格產(chan)品的(de)絕(jue)緣（護套）層柔(rou)軟、有韌性(xing)和伸縮性(xing)、表面層緊密、光滑(hua)、無粗糙(cao)感(gan)。如果包裹(guo)電(dian)線的(de)塑(su)料很容易被(bei)剝去，則存(cun)在塑(su)料強(qiang)度(du)不夠(gou)的(de)問(wen)題。

第二、要看電線的(de)(de)截面(mian)(mian)。合(he)格產品的(de)(de)銅芯或鋁(lv)芯表(biao)面(mian)(mian)應該具有金屬光澤(ze)，表(biao)面(mian)(mian)發黑的(de)(de)銅或表(biao)面(mian)(mian)發白的(de)(de)鋁(lv)說(shuo)明已被(bei)氧(yang)化。

第(di)三(san)、在(zai)購買電(dian)線時應注意查看(kan)質(zhi)量(liang)合(he)格證書。如果(guo)電(dian)線的質(zhi)量(liang)合(he)格，那么其電(dian)線質(zhi)量(liang)應該也(ye)受過檢驗，不會有太大的問題。
