不(bu)合格(ge)電(dian)線電(dian)纜的危害

電(dian)(dian)線(xian)電(dian)(dian)纜(lan)是用(yong)于傳(chuan)輸(shu)電(dian)(dian)力、傳(chuan)輸(shu)信息和實現電(dian)(dian)磁能(neng)量(liang)轉(zhuan)換的(de)一(yi)大類電(dian)(dian)工(gong)產品(pin)。在(zai)抽查過程中，發現了(le)大量(liang)的(de)不合格產品(pin)，這些劣質產品(pin)給電(dian)(dian)力系統正常運行埋下諸(zhu)多隱患(huan)。

1、標(biao)志不(bu)合(he)格的電線電纜。標(biao)志是電線電纜使用識別產(chan)品(pin)基本(ben)信息的主(zhu)要途徑(jing)，根(gen)據標(biao)準(zhun)規定標(biao)志的主(zhu)要內(nei)(nei)容是：產(chan)品(pin)型號、規格、標(biao)準(zhun)號、廠名、產(chan)地等在一定的標(biao)示間距內(nei)(nei)，當標(biao)志不(bu)合(he)格時，會(hui)造成(cheng)施工人員(yuan)識別錯誤(wu)，嚴重(zhong)時會(hui)引發電氣事故。

2、結構尺寸不(bu)合格的電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)。結構尺寸的主要(yao)問題是護(hu)套(tao)厚(hou)度(du)，絕(jue)緣厚(hou)度(du)，當電(dian)(dian)(dian)纜(lan)的護(hu)套(tao)和絕(jue)緣厚(hou)度(du)不(bu)達標時(shi)，致使(shi)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)耐電(dian)(dian)(dian)氣(qi)強度(du)會嚴(yan)重降低，導致電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)的使(shi)用壽命縮短，嚴(yan)重時(shi)可導致電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)被擊(ji)穿，絕(jue)緣（護(hu)套(tao)）層起(qi)不(bu)到(dao)正常(chang)保護(hu)作用，從(cong)而發生電(dian)(dian)(dian)氣(qi)短路和火災等現象。

3、護套(tao)(tao)式絕緣老化(hua)前的(de)抗(kang)張強度、伸(shen)長(chang)率合(he)格的(de)電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)。絕緣護套(tao)(tao)老化(hua)前的(de)抗(kang)張強度、伸(shen)長(chang)率不(bu)合(he)格直接(jie)大大縮短電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)的(de)工作用壽命(ming)，而且在施工或在長(chang)時間通電(dian)(dian)(dian)(dian)且溫(wen)度較高的(de)環(huan)境中，極易(yi)出(chu)現絕緣體(ti)斷裂(lie)，致使帶電(dian)(dian)(dian)(dian)導體(ti)裸(luo)露，發生能觸電(dian)(dian)(dian)(dian)式短路危(wei)險。其不(bu)合(he)格的(de)主(zhu)要原因是(shi)使用了(le)再生料生產，以降低產品成本，二是(shi)不(bu)具備生產資格小型企業。

4、導(dao)(dao)(dao)(dao)(dao)體(ti)(ti)(ti)電(dian)(dian)(dian)阻(zu)不合(he)(he)格的(de)電(dian)(dian)(dian)線(xian)。導(dao)(dao)(dao)(dao)(dao)體(ti)(ti)(ti)電(dian)(dian)(dian)阻(zu)主要是(shi)(shi)考核電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜的(de)導(dao)(dao)(dao)(dao)(dao)體(ti)(ti)(ti)材(cai)料(liao)以及截面是(shi)(shi)否符合(he)(he)的(de)重要指標。當導(dao)(dao)(dao)(dao)(dao)體(ti)(ti)(ti)電(dian)(dian)(dian)阻(zu)超(chao)(chao)標時，就增大了電(dian)(dian)(dian)流在(zai)線(xian)路上通過時的(de)損耗，加劇了電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜的(de)發熱。導(dao)(dao)(dao)(dao)(dao)體(ti)(ti)(ti)電(dian)(dian)(dian)阻(zu)不合(he)(he)格的(de)原因，主要進企業(ye)為了降低成(cheng)本(ben)，將(jiang)占原材(cai)料(liao)成(cheng)本(ben)80%的(de)銅材(cai)縮(suo)水，要么(me)降低導(dao)(dao)(dao)(dao)(dao)體(ti)(ti)(ti)的(de)截面積(ji)，要么(me)使(shi)用含雜質過高的(de)再生(sheng)銅，這樣致(zhi)使(shi)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜的(de)導(dao)(dao)(dao)(dao)(dao)體(ti)(ti)(ti)電(dian)(dian)(dian)阻(zu)嚴重超(chao)(chao)標，在(zai)使(shi)用過程中除易引發火災，還(huan)會加速包覆在(zai)電(dian)(dian)(dian)線(xian)外的(de)絕緣層的(de)老(lao)化。

在購買電線電纜的(de)過(guo)程(cheng)中(zhong)，消費者應注意以下幾個事

第一、要(yao)觀(guan)察電(dian)線(xian)的(de)外觀(guan)。合(he)格產品的(de)絕緣（護套）層(ceng)柔軟、有韌性和(he)伸縮性、表面層(ceng)緊密、光滑(hua)、無(wu)粗(cu)糙感。如(ru)果包裹電(dian)線(xian)的(de)塑(su)料很容易(yi)被剝去，則(ze)存在塑(su)料強度不(bu)夠的(de)問題。

第二(er)、要看電線的(de)(de)截面(mian)。合格(ge)產品的(de)(de)銅芯或鋁芯表(biao)面(mian)應該具有金屬光澤，表(biao)面(mian)發黑的(de)(de)銅或表(biao)面(mian)發白(bai)的(de)(de)鋁說(shuo)明已被氧化。

第三、在購買電線(xian)時(shi)應注(zhu)意查看(kan)質量(liang)合(he)格證書。如果電線(xian)的質量(liang)合(he)格，那么其電線(xian)質量(liang)應該也受過檢驗，不會有(you)太大的問題。
