不合格(ge)電線電纜的危害

電(dian)線電(dian)纜是用于傳輸電(dian)力(li)、傳輸信息和實現電(dian)磁能(neng)量轉(zhuan)換的一大(da)類電(dian)工產品。在抽查過(guo)程中，發現了大(da)量的不合(he)格產品，這些劣質產品給電(dian)力(li)系統正常運行埋下諸多隱患。

1、標志(zhi)(zhi)不(bu)(bu)合格的(de)電(dian)(dian)線(xian)電(dian)(dian)纜。標志(zhi)(zhi)是電(dian)(dian)線(xian)電(dian)(dian)纜使用識別(bie)產品基本(ben)信息的(de)主要(yao)(yao)途徑，根據標準規定標志(zhi)(zhi)的(de)主要(yao)(yao)內(nei)(nei)容是：產品型號(hao)、規格、標準號(hao)、廠名、產地等(deng)在一定的(de)標示間距內(nei)(nei)，當標志(zhi)(zhi)不(bu)(bu)合格時(shi)(shi)，會造成施工人員(yuan)識別(bie)錯誤(wu)，嚴重時(shi)(shi)會引(yin)發電(dian)(dian)氣(qi)事故。

2、結(jie)構(gou)尺(chi)(chi)寸不合格的(de)電(dian)(dian)線電(dian)(dian)纜。結(jie)構(gou)尺(chi)(chi)寸的(de)主要(yao)問題(ti)是護(hu)(hu)(hu)套厚(hou)度，絕緣厚(hou)度，當(dang)電(dian)(dian)纜的(de)護(hu)(hu)(hu)套和(he)絕緣厚(hou)度不達標時，致使電(dian)(dian)線電(dian)(dian)纜耐電(dian)(dian)氣(qi)強度會(hui)嚴重降低，導致電(dian)(dian)線電(dian)(dian)纜的(de)使用(yong)壽命(ming)縮短(duan)，嚴重時可導致電(dian)(dian)線電(dian)(dian)纜被擊穿，絕緣（護(hu)(hu)(hu)套）層起不到正常保(bao)護(hu)(hu)(hu)作用(yong)，從而發(fa)生電(dian)(dian)氣(qi)短(duan)路(lu)和(he)火災(zai)等現象。

3、護套(tao)式絕(jue)緣老(lao)化前的(de)抗(kang)張強度、伸長率合格的(de)電(dian)(dian)線(xian)電(dian)(dian)纜(lan)。絕(jue)緣護套(tao)老(lao)化前的(de)抗(kang)張強度、伸長率不合格直接(jie)大大縮短電(dian)(dian)線(xian)電(dian)(dian)纜(lan)的(de)工(gong)(gong)作用壽命(ming)，而且在(zai)施工(gong)(gong)或(huo)在(zai)長時間通電(dian)(dian)且溫(wen)度較(jiao)高的(de)環境中(zhong)，極(ji)易出現絕(jue)緣體(ti)斷裂，致(zhi)使帶電(dian)(dian)導體(ti)裸(luo)露，發生(sheng)(sheng)能觸(chu)電(dian)(dian)式短路危險。其不合格的(de)主要原因是使用了再(zai)生(sheng)(sheng)料生(sheng)(sheng)產，以降低(di)產品成本，二是不具備(bei)生(sheng)(sheng)產資格小型企業。

4、導(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)不(bu)合格的(de)(de)(de)電(dian)(dian)(dian)(dian)線(xian)(xian)。導(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)主(zhu)要是考核電(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)纜的(de)(de)(de)導(dao)體(ti)(ti)材料(liao)(liao)以及截面是否(fou)符合的(de)(de)(de)重要指標(biao)。當(dang)導(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)超標(biao)時，就增(zeng)大了電(dian)(dian)(dian)(dian)流(liu)在(zai)線(xian)(xian)路上(shang)通(tong)過(guo)時的(de)(de)(de)損耗，加劇了電(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)纜的(de)(de)(de)發(fa)熱。導(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)不(bu)合格的(de)(de)(de)原(yuan)因(yin)，主(zhu)要進企業為(wei)了降低(di)成本，將(jiang)占(zhan)原(yuan)材料(liao)(liao)成本80%的(de)(de)(de)銅材縮水，要么降低(di)導(dao)體(ti)(ti)的(de)(de)(de)截面積，要么使用含(han)雜質過(guo)高的(de)(de)(de)再生銅，這樣致使電(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)纜的(de)(de)(de)導(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)嚴重超標(biao)，在(zai)使用過(guo)程(cheng)中除易引發(fa)火災(zai)，還會加速包覆在(zai)電(dian)(dian)(dian)(dian)線(xian)(xian)外的(de)(de)(de)絕緣層的(de)(de)(de)老化(hua)。

在購買電線電纜(lan)的過(guo)程中，消費者應(ying)注意以(yi)下幾(ji)個事

第(di)一、要(yao)觀(guan)察電線的(de)外觀(guan)。合格產品的(de)絕緣（護(hu)套）層柔軟、有(you)韌性和伸(shen)縮性、表(biao)面層緊密、光滑、無粗糙感。如果包裹電線的(de)塑料很容易被(bei)剝去，則存在(zai)塑料強度不(bu)夠的(de)問題。

第二、要看電線的(de)截面(mian)。合格(ge)產品的(de)銅芯或鋁(lv)芯表(biao)面(mian)應該具有金屬光澤，表(biao)面(mian)發(fa)黑的(de)銅或表(biao)面(mian)發(fa)白的(de)鋁(lv)說(shuo)明(ming)已被氧化。

第三、在購(gou)買電線(xian)時應注意查看質(zhi)量合格證書。如果電線(xian)的質(zhi)量合格，那么其電線(xian)質(zhi)量應該也受過檢(jian)驗，不會有太(tai)大的問題。
