不合格電(dian)線電(dian)纜的危害

電線電纜是用于傳(chuan)輸電力、傳(chuan)輸信息和(he)實現(xian)電磁能量轉換的一大類電工產(chan)品(pin)。在抽查過程中(zhong)，發現(xian)了(le)大量的不(bu)合格產(chan)品(pin)，這些劣質產(chan)品(pin)給電力系統正常(chang)運行埋下諸(zhu)多隱患(huan)。

1、標(biao)(biao)志(zhi)不合(he)格的(de)電線電纜。標(biao)(biao)志(zhi)是電線電纜使用識別(bie)產(chan)品(pin)基本信息(xi)的(de)主(zhu)要途徑，根據標(biao)(biao)準規定(ding)標(biao)(biao)志(zhi)的(de)主(zhu)要內容是：產(chan)品(pin)型號、規格、標(biao)(biao)準號、廠名、產(chan)地等在一(yi)定(ding)的(de)標(biao)(biao)示間距內，當標(biao)(biao)志(zhi)不合(he)格時，會(hui)造成施工人員識別(bie)錯誤，嚴重時會(hui)引發(fa)電氣事(shi)故(gu)。

2、結構尺(chi)寸(cun)不合(he)格的(de)(de)電(dian)線(xian)電(dian)纜。結構尺(chi)寸(cun)的(de)(de)主(zhu)要問題是護套(tao)厚度(du)，絕緣厚度(du)，當電(dian)纜的(de)(de)護套(tao)和(he)絕緣厚度(du)不達標時，致(zhi)使電(dian)線(xian)電(dian)纜耐電(dian)氣強度(du)會嚴(yan)重降低，導致(zhi)電(dian)線(xian)電(dian)纜的(de)(de)使用(yong)壽命縮短，嚴(yan)重時可導致(zhi)電(dian)線(xian)電(dian)纜被擊穿，絕緣（護套(tao)）層起不到(dao)正(zheng)常保(bao)護作用(yong)，從而發生電(dian)氣短路和(he)火災(zai)等現(xian)象。

3、護套式(shi)絕(jue)(jue)緣老化(hua)前(qian)的(de)抗張(zhang)強度、伸長(chang)率合格的(de)電(dian)(dian)線(xian)(xian)電(dian)(dian)纜。絕(jue)(jue)緣護套老化(hua)前(qian)的(de)抗張(zhang)強度、伸長(chang)率不(bu)合格直接大大縮(suo)短(duan)電(dian)(dian)線(xian)(xian)電(dian)(dian)纜的(de)工作用壽命，而且(qie)在施工或在長(chang)時間通電(dian)(dian)且(qie)溫度較(jiao)高的(de)環境中，極(ji)易出現絕(jue)(jue)緣體斷(duan)裂，致使帶電(dian)(dian)導體裸露，發生(sheng)能觸電(dian)(dian)式(shi)短(duan)路危險(xian)。其(qi)不(bu)合格的(de)主(zhu)要(yao)原因是使用了再生(sheng)料(liao)生(sheng)產(chan)，以(yi)降(jiang)低產(chan)品成本，二是不(bu)具(ju)備(bei)生(sheng)產(chan)資格小型企業(ye)。

4、導(dao)(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)阻(zu)(zu)不合(he)格(ge)的(de)(de)(de)(de)電(dian)(dian)(dian)線(xian)(xian)。導(dao)(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)阻(zu)(zu)主(zhu)要(yao)(yao)是考(kao)核(he)電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜的(de)(de)(de)(de)導(dao)(dao)(dao)體(ti)(ti)材料以及截(jie)面是否符合(he)的(de)(de)(de)(de)重要(yao)(yao)指標。當導(dao)(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)阻(zu)(zu)超標時，就增(zeng)大了(le)電(dian)(dian)(dian)流在線(xian)(xian)路上通過(guo)時的(de)(de)(de)(de)損耗，加劇了(le)電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜的(de)(de)(de)(de)發熱(re)。導(dao)(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)阻(zu)(zu)不合(he)格(ge)的(de)(de)(de)(de)原因(yin)，主(zhu)要(yao)(yao)進企業為了(le)降(jiang)低成(cheng)(cheng)本，將占原材料成(cheng)(cheng)本80%的(de)(de)(de)(de)銅(tong)材縮水，要(yao)(yao)么(me)降(jiang)低導(dao)(dao)(dao)體(ti)(ti)的(de)(de)(de)(de)截(jie)面積，要(yao)(yao)么(me)使用含雜質過(guo)高的(de)(de)(de)(de)再(zai)生(sheng)銅(tong)，這樣(yang)致使電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜的(de)(de)(de)(de)導(dao)(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)阻(zu)(zu)嚴重超標，在使用過(guo)程中除易(yi)引(yin)發火(huo)災，還(huan)會加速包覆在電(dian)(dian)(dian)線(xian)(xian)外的(de)(de)(de)(de)絕緣層的(de)(de)(de)(de)老(lao)化(hua)。

在購買(mai)電線電纜的過程(cheng)中，消費者應(ying)注(zhu)意以下幾個事

第一、要觀察電(dian)線(xian)的(de)外觀。合(he)格產(chan)品的(de)絕緣(yuan)（護套）層柔軟、有韌性和伸縮性、表面層緊密、光滑、無粗糙感(gan)。如果包裹電(dian)線(xian)的(de)塑料(liao)很容易被(bei)剝去，則存在塑料(liao)強度不夠的(de)問(wen)題。

第二、要看電線的(de)截面。合格產(chan)品的(de)銅芯或鋁(lv)芯表(biao)面應(ying)該具有金屬光澤，表(biao)面發黑(hei)的(de)銅或表(biao)面發白的(de)鋁(lv)說(shuo)明已被(bei)氧化。

第三、在購買(mai)電(dian)線(xian)時應(ying)注(zhu)意查看質量(liang)(liang)合(he)格證書。如果(guo)電(dian)線(xian)的質量(liang)(liang)合(he)格，那么其電(dian)線(xian)質量(liang)(liang)應(ying)該(gai)也受(shou)過檢驗(yan)，不會(hui)有太(tai)大的問(wen)題。
