不合(he)格電(dian)線電(dian)纜的危害

電(dian)(dian)線電(dian)(dian)纜(lan)是用于傳(chuan)輸(shu)電(dian)(dian)力(li)、傳(chuan)輸(shu)信息和實現電(dian)(dian)磁能量轉換的一(yi)大(da)類電(dian)(dian)工產(chan)品(pin)(pin)。在抽查過程中(zhong)，發現了大(da)量的不合格產(chan)品(pin)(pin)，這些劣(lie)質(zhi)產(chan)品(pin)(pin)給電(dian)(dian)力(li)系統(tong)正常運行埋下諸(zhu)多隱(yin)患。

1、標(biao)(biao)(biao)志(zhi)(zhi)不(bu)合格的(de)(de)電線電纜(lan)。標(biao)(biao)(biao)志(zhi)(zhi)是(shi)電線電纜(lan)使用識別(bie)產(chan)品基本信息(xi)的(de)(de)主要途徑，根據標(biao)(biao)(biao)準(zhun)規(gui)定標(biao)(biao)(biao)志(zhi)(zhi)的(de)(de)主要內容是(shi)：產(chan)品型號(hao)、規(gui)格、標(biao)(biao)(biao)準(zhun)號(hao)、廠名、產(chan)地等(deng)在(zai)一定的(de)(de)標(biao)(biao)(biao)示間距內，當標(biao)(biao)(biao)志(zhi)(zhi)不(bu)合格時，會(hui)造(zao)成(cheng)施工人員識別(bie)錯誤，嚴重時會(hui)引發電氣事故。

2、結構(gou)尺寸(cun)不(bu)(bu)合格的(de)電(dian)線(xian)電(dian)纜。結構(gou)尺寸(cun)的(de)主(zhu)要(yao)問題是護(hu)套厚度，絕(jue)(jue)緣厚度，當電(dian)纜的(de)護(hu)套和絕(jue)(jue)緣厚度不(bu)(bu)達(da)標(biao)時，致(zhi)使電(dian)線(xian)電(dian)纜耐(nai)電(dian)氣(qi)強度會嚴(yan)重(zhong)降低，導致(zhi)電(dian)線(xian)電(dian)纜的(de)使用(yong)壽命縮短，嚴(yan)重(zhong)時可(ke)導致(zhi)電(dian)線(xian)電(dian)纜被擊穿，絕(jue)(jue)緣（護(hu)套）層起不(bu)(bu)到正常保護(hu)作用(yong)，從(cong)而(er)發(fa)生電(dian)氣(qi)短路和火災等現象。

3、護套(tao)式絕(jue)緣老(lao)化(hua)(hua)前的(de)(de)抗張強(qiang)度、伸(shen)長率合格(ge)的(de)(de)電(dian)線(xian)電(dian)纜。絕(jue)緣護套(tao)老(lao)化(hua)(hua)前的(de)(de)抗張強(qiang)度、伸(shen)長率不合格(ge)直接大大縮短電(dian)線(xian)電(dian)纜的(de)(de)工作用(yong)壽命，而且在施(shi)工或在長時間通(tong)電(dian)且溫度較高的(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(sheng)能觸電(dian)式短路危險。其不合格(ge)的(de)(de)主要原因是(shi)使用(yong)了再(zai)生(sheng)料生(sheng)產(chan)，以(yi)降低產(chan)品成本，二是(shi)不具備生(sheng)產(chan)資格(ge)小型企業(ye)。

4、導(dao)(dao)體(ti)電(dian)(dian)(dian)阻(zu)(zu)不合格(ge)的(de)電(dian)(dian)(dian)線(xian)。導(dao)(dao)體(ti)電(dian)(dian)(dian)阻(zu)(zu)主要是(shi)考核電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜的(de)導(dao)(dao)體(ti)材(cai)料(liao)以及截面(mian)是(shi)否符(fu)合的(de)重要指標(biao)。當導(dao)(dao)體(ti)電(dian)(dian)(dian)阻(zu)(zu)超(chao)標(biao)時，就增(zeng)大了電(dian)(dian)(dian)流在(zai)(zai)線(xian)路(lu)上通過(guo)時的(de)損耗，加劇(ju)了電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜的(de)發熱。導(dao)(dao)體(ti)電(dian)(dian)(dian)阻(zu)(zu)不合格(ge)的(de)原因(yin)，主要進企業為了降低成本，將占原材(cai)料(liao)成本80%的(de)銅材(cai)縮水，要么降低導(dao)(dao)體(ti)的(de)截面(mian)積，要么使用(yong)(yong)含雜質過(guo)高的(de)再生銅，這(zhe)樣致使電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜的(de)導(dao)(dao)體(ti)電(dian)(dian)(dian)阻(zu)(zu)嚴重超(chao)標(biao)，在(zai)(zai)使用(yong)(yong)過(guo)程中除易引發火災(zai)，還會加速包覆在(zai)(zai)電(dian)(dian)(dian)線(xian)外(wai)的(de)絕緣層的(de)老化。

在購(gou)買(mai)電線(xian)電纜的過程中，消(xiao)費者(zhe)應注意(yi)以下(xia)幾個事

第一、要觀察電線(xian)(xian)的(de)外(wai)觀。合(he)格產(chan)品的(de)絕(jue)緣（護套(tao)）層柔(rou)軟、有韌性和伸縮(suo)性、表(biao)面層緊密、光滑(hua)、無粗(cu)糙感。如果包裹電線(xian)(xian)的(de)塑料(liao)很(hen)容易被(bei)剝去，則存在塑料(liao)強度不(bu)夠的(de)問題。

第二、要看電線的(de)截面(mian)(mian)。合格產品的(de)銅芯或(huo)鋁芯表(biao)面(mian)(mian)應該具有金屬光(guang)澤，表(biao)面(mian)(mian)發黑的(de)銅或(huo)表(biao)面(mian)(mian)發白的(de)鋁說明(ming)已被氧(yang)化。

第三、在購(gou)買電線(xian)(xian)時(shi)應(ying)注意查看質量(liang)合格(ge)證書。如果電線(xian)(xian)的質量(liang)合格(ge)，那么其電線(xian)(xian)質量(liang)應(ying)該也受過檢驗，不會(hui)有太大的問題。
