不合格電線電纜(lan)的(de)危害

電(dian)(dian)線電(dian)(dian)纜是用于傳(chuan)輸(shu)電(dian)(dian)力、傳(chuan)輸(shu)信息(xi)和(he)實(shi)現電(dian)(dian)磁能(neng)量(liang)轉換的一(yi)大類電(dian)(dian)工產品。在抽查(cha)過程中，發現了大量(liang)的不(bu)合格產品，這些劣質(zhi)產品給電(dian)(dian)力系統正常運(yun)行埋下(xia)諸多隱患。

1、標(biao)志不(bu)合格的(de)電(dian)線電(dian)纜。標(biao)志是電(dian)線電(dian)纜使用識(shi)別產(chan)品基(ji)本信息的(de)主要(yao)途徑，根據標(biao)準規(gui)定標(biao)志的(de)主要(yao)內容是：產(chan)品型號、規(gui)格、標(biao)準號、廠名、產(chan)地等在一定的(de)標(biao)示間距(ju)內，當標(biao)志不(bu)合格時(shi)，會造成施工人員識(shi)別錯誤，嚴重(zhong)時(shi)會引發電(dian)氣(qi)事故。

2、結(jie)構(gou)尺(chi)寸(cun)不合格的(de)(de)(de)電(dian)(dian)線(xian)電(dian)(dian)纜。結(jie)構(gou)尺(chi)寸(cun)的(de)(de)(de)主要問(wen)題是護(hu)(hu)套厚(hou)度(du)，絕(jue)緣厚(hou)度(du)，當電(dian)(dian)纜的(de)(de)(de)護(hu)(hu)套和絕(jue)緣厚(hou)度(du)不達標時(shi)，致使電(dian)(dian)線(xian)電(dian)(dian)纜耐電(dian)(dian)氣強(qiang)度(du)會嚴重降低(di)，導致電(dian)(dian)線(xian)電(dian)(dian)纜的(de)(de)(de)使用壽命縮短，嚴重時(shi)可導致電(dian)(dian)線(xian)電(dian)(dian)纜被擊(ji)穿，絕(jue)緣（護(hu)(hu)套）層起不到正(zheng)常(chang)保(bao)護(hu)(hu)作用，從而(er)發生電(dian)(dian)氣短路和火災等現象。

3、護(hu)套(tao)式(shi)絕緣(yuan)(yuan)老(lao)化前的抗張強(qiang)度(du)、伸(shen)(shen)長(chang)率(lv)(lv)合格(ge)的電線電纜(lan)。絕緣(yuan)(yuan)護(hu)套(tao)老(lao)化前的抗張強(qiang)度(du)、伸(shen)(shen)長(chang)率(lv)(lv)不合格(ge)直接大大縮短電線電纜(lan)的工作(zuo)用(yong)壽命，而且(qie)(qie)在(zai)施工或在(zai)長(chang)時(shi)間通電且(qie)(qie)溫度(du)較高的環境中，極易出現(xian)絕緣(yuan)(yuan)體斷(duan)裂，致使帶(dai)電導體裸露(lu)，發生(sheng)能觸電式(shi)短路危(wei)險。其(qi)不合格(ge)的主要原因(yin)是使用(yong)了再生(sheng)料生(sheng)產(chan)(chan)，以降低(di)產(chan)(chan)品成本，二(er)是不具備生(sheng)產(chan)(chan)資格(ge)小(xiao)型(xing)企業。

4、導(dao)(dao)(dao)體電(dian)(dian)(dian)阻(zu)(zu)不(bu)合格的(de)(de)電(dian)(dian)(dian)線(xian)(xian)。導(dao)(dao)(dao)體電(dian)(dian)(dian)阻(zu)(zu)主要是(shi)考核電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)的(de)(de)導(dao)(dao)(dao)體材(cai)料以及截面(mian)是(shi)否符(fu)合的(de)(de)重要指(zhi)標。當導(dao)(dao)(dao)體電(dian)(dian)(dian)阻(zu)(zu)超標時，就增(zeng)大了(le)電(dian)(dian)(dian)流(liu)在線(xian)(xian)路(lu)上通過時的(de)(de)損耗(hao)，加劇了(le)電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)的(de)(de)發熱(re)。導(dao)(dao)(dao)體電(dian)(dian)(dian)阻(zu)(zu)不(bu)合格的(de)(de)原因，主要進(jin)企業為了(le)降(jiang)低成本，將(jiang)占原材(cai)料成本80%的(de)(de)銅材(cai)縮(suo)水(shui)，要么(me)(me)降(jiang)低導(dao)(dao)(dao)體的(de)(de)截面(mian)積(ji)，要么(me)(me)使用(yong)含雜(za)質過高的(de)(de)再生銅，這(zhe)樣致使電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)的(de)(de)導(dao)(dao)(dao)體電(dian)(dian)(dian)阻(zu)(zu)嚴重超標，在使用(yong)過程中除易引發火災(zai)，還會加速包覆在電(dian)(dian)(dian)線(xian)(xian)外的(de)(de)絕緣(yuan)層的(de)(de)老(lao)化。

在購買電線電纜的過(guo)程中，消費者應注意(yi)以下幾個(ge)事

第一、要觀察(cha)電(dian)線(xian)的(de)(de)外觀。合格產品的(de)(de)絕緣（護套）層柔軟、有韌性(xing)和伸縮性(xing)、表面層緊密、光滑、無(wu)粗(cu)糙感。如果包裹電(dian)線(xian)的(de)(de)塑料很容易被剝去(qu)，則存在塑料強度不夠(gou)的(de)(de)問題。

第二、要看電(dian)線的(de)截面。合(he)格產品的(de)銅(tong)芯或(huo)鋁(lv)芯表面應該具有金屬(shu)光澤，表面發(fa)黑的(de)銅(tong)或(huo)表面發(fa)白的(de)鋁(lv)說明已被氧化。

第三、在購買電(dian)線(xian)時應(ying)注(zhu)意查看質量(liang)合(he)格(ge)證書。如(ru)果電(dian)線(xian)的質量(liang)合(he)格(ge)，那(nei)么其電(dian)線(xian)質量(liang)應(ying)該(gai)也受(shou)過檢驗(yan)，不會(hui)有太(tai)大的問題。
