不合(he)格電線(xian)電纜的危害

電線電纜是用于傳(chuan)輸(shu)電力、傳(chuan)輸(shu)信息(xi)和實現(xian)電磁能量轉換的一大類(lei)電工產(chan)品。在抽查過程中(zhong)，發現(xian)了大量的不合格產(chan)品，這些劣質(zhi)產(chan)品給(gei)電力系統正(zheng)常運(yun)行埋下(xia)諸多隱患。

1、標(biao)(biao)(biao)(biao)志不合(he)(he)格的(de)(de)電線電纜。標(biao)(biao)(biao)(biao)志是電線電纜使(shi)用識別產品(pin)基本(ben)信息的(de)(de)主要途徑，根(gen)據標(biao)(biao)(biao)(biao)準規定標(biao)(biao)(biao)(biao)志的(de)(de)主要內容是：產品(pin)型號、規格、標(biao)(biao)(biao)(biao)準號、廠名(ming)、產地等在一定的(de)(de)標(biao)(biao)(biao)(biao)示間(jian)距內，當標(biao)(biao)(biao)(biao)志不合(he)(he)格時，會造成施(shi)工(gong)人員(yuan)識別錯(cuo)誤，嚴重時會引發電氣事故。

2、結(jie)構(gou)尺寸不合格的(de)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜。結(jie)構(gou)尺寸的(de)主(zhu)要問題是護(hu)套(tao)(tao)厚度(du)，絕(jue)(jue)緣(yuan)厚度(du)，當電(dian)(dian)(dian)纜的(de)護(hu)套(tao)(tao)和絕(jue)(jue)緣(yuan)厚度(du)不達標時，致(zhi)使電(dian)(dian)(dian)線電(dian)(dian)(dian)纜耐電(dian)(dian)(dian)氣(qi)強度(du)會(hui)嚴重降低，導致(zhi)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜的(de)使用壽命縮短，嚴重時可導致(zhi)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜被(bei)擊穿(chuan)，絕(jue)(jue)緣(yuan)（護(hu)套(tao)(tao)）層起不到正常保護(hu)作用，從而發生電(dian)(dian)(dian)氣(qi)短路和火災(zai)等現象(xiang)。

3、護(hu)套式(shi)絕(jue)緣(yuan)老化前(qian)的(de)(de)抗張強度、伸長率合格(ge)的(de)(de)電(dian)線電(dian)纜(lan)。絕(jue)緣(yuan)護(hu)套老化前(qian)的(de)(de)抗張強度、伸長率不(bu)合格(ge)直接大大縮短電(dian)線電(dian)纜(lan)的(de)(de)工作用壽命，而且在施工或在長時間通(tong)電(dian)且溫度較高的(de)(de)環境中，極(ji)易(yi)出現絕(jue)緣(yuan)體斷裂，致(zhi)使帶電(dian)導體裸(luo)露，發生能觸電(dian)式(shi)短路危險。其不(bu)合格(ge)的(de)(de)主要原因是使用了(le)再生料生產(chan)(chan)，以降低產(chan)(chan)品成本，二是不(bu)具(ju)備生產(chan)(chan)資格(ge)小型(xing)企業。

4、導(dao)體(ti)電(dian)(dian)(dian)(dian)(dian)阻(zu)不(bu)合(he)(he)格的(de)(de)電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)。導(dao)體(ti)電(dian)(dian)(dian)(dian)(dian)阻(zu)主(zhu)要(yao)是(shi)考核(he)電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)(dian)(dian)纜(lan)的(de)(de)導(dao)體(ti)材料(liao)以及截(jie)面是(shi)否符(fu)合(he)(he)的(de)(de)重要(yao)指(zhi)標(biao)。當導(dao)體(ti)電(dian)(dian)(dian)(dian)(dian)阻(zu)超(chao)標(biao)時(shi)，就(jiu)增大了電(dian)(dian)(dian)(dian)(dian)流在線(xian)(xian)(xian)路上通(tong)過時(shi)的(de)(de)損耗，加(jia)劇了電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)(dian)(dian)纜(lan)的(de)(de)發熱。導(dao)體(ti)電(dian)(dian)(dian)(dian)(dian)阻(zu)不(bu)合(he)(he)格的(de)(de)原因，主(zhu)要(yao)進(jin)企業(ye)為了降低(di)成本(ben)，將(jiang)占原材料(liao)成本(ben)80%的(de)(de)銅材縮水，要(yao)么(me)降低(di)導(dao)體(ti)的(de)(de)截(jie)面積，要(yao)么(me)使用含雜質過高的(de)(de)再生(sheng)銅，這樣(yang)致使電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)(dian)(dian)纜(lan)的(de)(de)導(dao)體(ti)電(dian)(dian)(dian)(dian)(dian)阻(zu)嚴重超(chao)標(biao)，在使用過程(cheng)中除易引(yin)發火災，還會(hui)加(jia)速包覆(fu)在電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)外的(de)(de)絕(jue)緣(yuan)層的(de)(de)老化。

在購買電線電纜的過程中，消費者應注意(yi)以下幾個事(shi)

第一、要觀察電線的外觀。合格產品(pin)的絕緣(yuan)（護套(tao)）層柔軟、有韌性和伸縮性、表(biao)面層緊密、光(guang)滑(hua)、無(wu)粗糙(cao)感。如(ru)果包裹電線的塑(su)(su)料(liao)很容易被剝去，則存在塑(su)(su)料(liao)強度不夠(gou)的問題。

第二、要看電線的截面(mian)(mian)。合格產(chan)品(pin)的銅芯或鋁(lv)芯表面(mian)(mian)應該具有金屬(shu)光(guang)澤，表面(mian)(mian)發黑的銅或表面(mian)(mian)發白的鋁(lv)說明(ming)已被氧化。

第三、在購買電(dian)線(xian)時應注意查看質量(liang)合格證書。如(ru)果電(dian)線(xian)的質量(liang)合格，那么其電(dian)線(xian)質量(liang)應該也(ye)受過(guo)檢驗，不會有(you)太大的問題(ti)。
