不合格電線電纜的危(wei)害

電(dian)線電(dian)纜是用于傳輸(shu)(shu)電(dian)力(li)、傳輸(shu)(shu)信息和實現電(dian)磁能量轉換的一大(da)類(lei)電(dian)工產(chan)品(pin)。在抽查過程中，發現了(le)大(da)量的不合格產(chan)品(pin)，這些劣質(zhi)產(chan)品(pin)給電(dian)力(li)系統正常運行埋下諸(zhu)多隱患(huan)。

1、標志(zhi)不(bu)合(he)格(ge)的(de)電(dian)線電(dian)纜。標志(zhi)是電(dian)線電(dian)纜使用識別(bie)產(chan)品(pin)基本信息(xi)的(de)主要(yao)途徑，根(gen)據標準規定標志(zhi)的(de)主要(yao)內容是：產(chan)品(pin)型號(hao)(hao)、規格(ge)、標準號(hao)(hao)、廠名、產(chan)地等在一定的(de)標示(shi)間(jian)距內，當標志(zhi)不(bu)合(he)格(ge)時，會造成施工(gong)人員(yuan)識別(bie)錯誤，嚴重時會引發電(dian)氣(qi)事故。

2、結構(gou)尺寸(cun)不(bu)合格的(de)(de)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)。結構(gou)尺寸(cun)的(de)(de)主(zhu)要(yao)問題是(shi)護(hu)(hu)套厚度(du)，絕緣厚度(du)，當電(dian)(dian)(dian)纜(lan)的(de)(de)護(hu)(hu)套和絕緣厚度(du)不(bu)達標時，致(zhi)使電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)耐電(dian)(dian)(dian)氣(qi)(qi)強度(du)會嚴(yan)重(zhong)降低，導(dao)致(zhi)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)的(de)(de)使用(yong)壽命縮短，嚴(yan)重(zhong)時可導(dao)致(zhi)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)被(bei)擊(ji)穿(chuan)，絕緣（護(hu)(hu)套）層起不(bu)到正常(chang)保(bao)護(hu)(hu)作(zuo)用(yong)，從(cong)而發(fa)生(sheng)電(dian)(dian)(dian)氣(qi)(qi)短路和火災等現象。

3、護套(tao)式(shi)絕緣(yuan)老化(hua)前(qian)的(de)抗(kang)張強度(du)、伸長率(lv)(lv)合格的(de)電(dian)(dian)線(xian)(xian)電(dian)(dian)纜。絕緣(yuan)護套(tao)老化(hua)前(qian)的(de)抗(kang)張強度(du)、伸長率(lv)(lv)不合格直接大大縮(suo)短電(dian)(dian)線(xian)(xian)電(dian)(dian)纜的(de)工(gong)作(zuo)用(yong)(yong)壽(shou)命，而且在施工(gong)或在長時間通電(dian)(dian)且溫(wen)度(du)較高的(de)環境中，極(ji)易出現絕緣(yuan)體(ti)斷裂(lie)，致使(shi)(shi)帶電(dian)(dian)導體(ti)裸露，發生能(neng)觸電(dian)(dian)式(shi)短路危險。其不合格的(de)主要原因(yin)是使(shi)(shi)用(yong)(yong)了再生料生產(chan)，以降低產(chan)品(pin)成本(ben)，二(er)是不具備生產(chan)資格小型(xing)企業。

4、導(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)(zu)不合(he)格的(de)(de)電(dian)(dian)(dian)(dian)線(xian)。導(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)(zu)主要(yao)(yao)(yao)是(shi)考核(he)電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)的(de)(de)導(dao)體(ti)(ti)材料以及截(jie)面是(shi)否符(fu)合(he)的(de)(de)重要(yao)(yao)(yao)指(zhi)標(biao)。當導(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)(zu)超(chao)標(biao)時，就(jiu)增大了(le)電(dian)(dian)(dian)(dian)流在(zai)線(xian)路上(shang)通過(guo)(guo)時的(de)(de)損(sun)耗(hao)，加劇了(le)電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)的(de)(de)發(fa)熱。導(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)(zu)不合(he)格的(de)(de)原因，主要(yao)(yao)(yao)進企業為了(le)降低(di)成本，將占原材料成本80%的(de)(de)銅(tong)材縮水，要(yao)(yao)(yao)么降低(di)導(dao)體(ti)(ti)的(de)(de)截(jie)面積，要(yao)(yao)(yao)么使(shi)用含雜質過(guo)(guo)高的(de)(de)再生銅(tong)，這樣致使(shi)電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)的(de)(de)導(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)(zu)嚴重超(chao)標(biao)，在(zai)使(shi)用過(guo)(guo)程中除(chu)易引(yin)發(fa)火(huo)災，還會加速(su)包覆在(zai)電(dian)(dian)(dian)(dian)線(xian)外(wai)的(de)(de)絕緣層(ceng)的(de)(de)老化。

在購買電(dian)線電(dian)纜的過程中，消費(fei)者(zhe)應注意以下幾個事(shi)

第一、要觀察電線(xian)的外觀。合格產品的絕(jue)緣(yuan)（護套）層柔軟、有韌性和伸縮性、表面層緊(jin)密、光滑、無粗糙感(gan)。如果包(bao)裹電線(xian)的塑(su)料(liao)很容易被剝去，則存在塑(su)料(liao)強度不(bu)夠(gou)的問題。

第二、要(yao)看電線的(de)截面(mian)。合(he)格產品(pin)的(de)銅芯(xin)或(huo)鋁(lv)芯(xin)表(biao)面(mian)應該具(ju)有(you)金屬光(guang)澤，表(biao)面(mian)發(fa)黑的(de)銅或(huo)表(biao)面(mian)發(fa)白的(de)鋁(lv)說明已被氧化。

第(di)三、在購買電線(xian)時應注意查看(kan)質(zhi)量合格證(zheng)書。如果(guo)電線(xian)的質(zhi)量合格，那么其(qi)電線(xian)質(zhi)量應該(gai)也受過(guo)檢驗(yan)，不會有太(tai)大(da)的問題。
