不合格電線電纜的危害

電(dian)(dian)線電(dian)(dian)纜是用于(yu)傳輸電(dian)(dian)力、傳輸信息和(he)實現電(dian)(dian)磁能(neng)量(liang)轉換的一大類電(dian)(dian)工產品(pin)。在抽查過程中，發(fa)現了大量(liang)的不合(he)格產品(pin)，這些劣質(zhi)產品(pin)給電(dian)(dian)力系統正常運(yun)行埋下諸多(duo)隱患(huan)。

1、標(biao)志不(bu)(bu)合(he)格(ge)的(de)(de)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)。標(biao)志是(shi)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)使用識別產(chan)(chan)品(pin)基本信息的(de)(de)主(zhu)要途(tu)徑，根據標(biao)準規(gui)定標(biao)志的(de)(de)主(zhu)要內(nei)容是(shi)：產(chan)(chan)品(pin)型號、規(gui)格(ge)、標(biao)準號、廠名、產(chan)(chan)地等在一定的(de)(de)標(biao)示間距內(nei)，當標(biao)志不(bu)(bu)合(he)格(ge)時，會造成施工(gong)人員識別錯誤，嚴重時會引發電(dian)(dian)(dian)氣事故。

2、結構(gou)(gou)尺寸不合格的(de)電(dian)(dian)線(xian)(xian)電(dian)(dian)纜(lan)(lan)。結構(gou)(gou)尺寸的(de)主要問題是護套(tao)(tao)厚(hou)度(du)(du)，絕(jue)緣(yuan)厚(hou)度(du)(du)，當電(dian)(dian)纜(lan)(lan)的(de)護套(tao)(tao)和絕(jue)緣(yuan)厚(hou)度(du)(du)不達標時，致(zhi)使(shi)電(dian)(dian)線(xian)(xian)電(dian)(dian)纜(lan)(lan)耐電(dian)(dian)氣強(qiang)度(du)(du)會嚴重(zhong)降(jiang)低，導致(zhi)電(dian)(dian)線(xian)(xian)電(dian)(dian)纜(lan)(lan)的(de)使(shi)用(yong)壽(shou)命縮短，嚴重(zhong)時可(ke)導致(zhi)電(dian)(dian)線(xian)(xian)電(dian)(dian)纜(lan)(lan)被(bei)擊穿，絕(jue)緣(yuan)（護套(tao)(tao)）層起不到正常保護作用(yong)，從而(er)發生電(dian)(dian)氣短路和火(huo)災(zai)等(deng)現象。

3、護套式絕(jue)(jue)緣老化(hua)前的(de)(de)抗張強(qiang)度(du)、伸長(chang)率(lv)合格(ge)的(de)(de)電(dian)線電(dian)纜(lan)(lan)。絕(jue)(jue)緣護套老化(hua)前的(de)(de)抗張強(qiang)度(du)、伸長(chang)率(lv)不(bu)合格(ge)直接大(da)大(da)縮短(duan)電(dian)線電(dian)纜(lan)(lan)的(de)(de)工(gong)作用壽命，而且在施工(gong)或在長(chang)時間(jian)通電(dian)且溫度(du)較(jiao)高的(de)(de)環(huan)境中，極易出現絕(jue)(jue)緣體斷裂，致(zhi)使帶電(dian)導體裸(luo)露，發生能觸電(dian)式短(duan)路危險。其(qi)不(bu)合格(ge)的(de)(de)主要原因是使用了再(zai)生料生產，以降低產品成(cheng)本，二是不(bu)具備生產資格(ge)小型企業。

4、導(dao)體(ti)(ti)(ti)電(dian)(dian)(dian)阻(zu)不(bu)合格的電(dian)(dian)(dian)線(xian)(xian)。導(dao)體(ti)(ti)(ti)電(dian)(dian)(dian)阻(zu)主(zhu)要是(shi)考核電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)(lan)的導(dao)體(ti)(ti)(ti)材料以及截面是(shi)否符合的重要指標。當導(dao)體(ti)(ti)(ti)電(dian)(dian)(dian)阻(zu)超(chao)標時，就增大了電(dian)(dian)(dian)流在(zai)線(xian)(xian)路上通(tong)過時的損耗，加劇(ju)了電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)(lan)的發熱。導(dao)體(ti)(ti)(ti)電(dian)(dian)(dian)阻(zu)不(bu)合格的原因，主(zhu)要進企業為了降(jiang)低(di)成本，將占原材料成本80%的銅材縮水，要么降(jiang)低(di)導(dao)體(ti)(ti)(ti)的截面積，要么使(shi)用含雜質過高的再生銅，這(zhe)樣致使(shi)電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)(lan)的導(dao)體(ti)(ti)(ti)電(dian)(dian)(dian)阻(zu)嚴重超(chao)標，在(zai)使(shi)用過程中除易引發火(huo)災，還會加速包(bao)覆在(zai)電(dian)(dian)(dian)線(xian)(xian)外的絕緣(yuan)層的老化。

在購買電線電纜(lan)的過程中，消費者應注意以下幾個(ge)事

第一、要觀(guan)察(cha)電(dian)(dian)線(xian)的(de)(de)外觀(guan)。合格產品的(de)(de)絕緣（護(hu)套）層柔軟、有韌(ren)性和伸縮(suo)性、表面層緊密(mi)、光滑(hua)、無粗糙感(gan)。如果包裹電(dian)(dian)線(xian)的(de)(de)塑料很容易被剝去，則存在塑料強度不夠的(de)(de)問題(ti)。

第二、要看電線(xian)的(de)(de)截面(mian)(mian)。合格(ge)產(chan)品的(de)(de)銅芯或鋁(lv)芯表(biao)面(mian)(mian)應該(gai)具有(you)金屬光(guang)澤，表(biao)面(mian)(mian)發黑的(de)(de)銅或表(biao)面(mian)(mian)發白的(de)(de)鋁(lv)說明已被氧化(hua)。

第三、在購買電線時應注意(yi)查看質量合(he)格證書。如果電線的質量合(he)格，那么其電線質量應該也(ye)受(shou)過檢驗，不會有太大的問(wen)題。
