不合格(ge)電(dian)線電(dian)纜的危(wei)害

電(dian)線電(dian)纜是(shi)用于傳輸電(dian)力、傳輸信息(xi)和實現電(dian)磁能量轉換的一大類(lei)電(dian)工產品。在抽查(cha)過程中，發現了(le)大量的不合格產品，這些(xie)劣質產品給電(dian)力系統正常(chang)運(yun)行埋下(xia)諸多隱(yin)患。

1、標(biao)志不合格的(de)電線(xian)電纜。標(biao)志是電線(xian)電纜使(shi)用識(shi)別(bie)產品基本信(xin)息的(de)主要(yao)途徑，根據標(biao)準規定(ding)標(biao)志的(de)主要(yao)內(nei)容是：產品型號、規格、標(biao)準號、廠(chang)名(ming)、產地等在一定(ding)的(de)標(biao)示(shi)間距內(nei)，當標(biao)志不合格時，會造成施(shi)工人員識(shi)別(bie)錯誤，嚴重時會引發電氣事故。

2、結(jie)構尺寸不合(he)格的(de)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)(lan)。結(jie)構尺寸的(de)主要問題是護(hu)套(tao)厚(hou)(hou)度，絕(jue)緣厚(hou)(hou)度，當電(dian)(dian)(dian)纜(lan)(lan)的(de)護(hu)套(tao)和絕(jue)緣厚(hou)(hou)度不達標(biao)時，致(zhi)使電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)(lan)耐電(dian)(dian)(dian)氣(qi)強度會嚴重降低，導(dao)致(zhi)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)(lan)的(de)使用(yong)壽(shou)命縮短，嚴重時可導(dao)致(zhi)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)(lan)被擊穿，絕(jue)緣（護(hu)套(tao)）層(ceng)起不到正(zheng)常(chang)保護(hu)作用(yong)，從而發生電(dian)(dian)(dian)氣(qi)短路和火災等現象。

3、護套(tao)式絕緣(yuan)老(lao)化(hua)前的(de)抗(kang)張強度(du)(du)、伸長率合(he)格(ge)的(de)電線電纜(lan)。絕緣(yuan)護套(tao)老(lao)化(hua)前的(de)抗(kang)張強度(du)(du)、伸長率不合(he)格(ge)直接大大縮(suo)短電線電纜(lan)的(de)工作(zuo)用壽命，而且在施工或在長時間(jian)通電且溫度(du)(du)較高的(de)環境中，極易出現(xian)絕緣(yuan)體(ti)斷裂，致(zhi)使(shi)帶電導(dao)體(ti)裸露，發生能觸電式短路危險。其不合(he)格(ge)的(de)主要原因是使(shi)用了再生料生產，以降低(di)產品成(cheng)本，二是不具備生產資格(ge)小型企(qi)業。

4、導(dao)(dao)(dao)體(ti)電阻不(bu)合格的(de)(de)(de)電線。導(dao)(dao)(dao)體(ti)電阻主(zhu)要是考核電線電纜的(de)(de)(de)導(dao)(dao)(dao)體(ti)材(cai)料(liao)以及(ji)截面(mian)是否符合的(de)(de)(de)重要指(zhi)標。當導(dao)(dao)(dao)體(ti)電阻超標時(shi)，就增大了電流(liu)在線路(lu)上通(tong)過(guo)時(shi)的(de)(de)(de)損耗，加劇了電線電纜的(de)(de)(de)發熱(re)。導(dao)(dao)(dao)體(ti)電阻不(bu)合格的(de)(de)(de)原因，主(zhu)要進企業為了降(jiang)低成本，將占原材(cai)料(liao)成本80%的(de)(de)(de)銅材(cai)縮水，要么(me)降(jiang)低導(dao)(dao)(dao)體(ti)的(de)(de)(de)截面(mian)積，要么(me)使(shi)用含雜質過(guo)高(gao)的(de)(de)(de)再(zai)生銅，這樣致使(shi)電線電纜的(de)(de)(de)導(dao)(dao)(dao)體(ti)電阻嚴重超標，在使(shi)用過(guo)程中除易引發火災，還會加速包覆在電線外的(de)(de)(de)絕緣層的(de)(de)(de)老化。

在購買電線電纜的過程中，消費者應(ying)注意以下幾個(ge)事

第一、要(yao)觀察電線的外(wai)觀。合格產(chan)品的絕緣(yuan)（護套）層(ceng)柔軟、有韌性(xing)和伸縮性(xing)、表面層(ceng)緊密、光滑、無粗糙(cao)感(gan)。如(ru)果包裹電線的塑料很容(rong)易被剝去(qu)，則存(cun)在塑料強度不夠的問題。

第二(er)、要看電(dian)線(xian)的截面。合格產品的銅(tong)芯(xin)或鋁芯(xin)表(biao)面應該具有金屬光澤，表(biao)面發黑的銅(tong)或表(biao)面發白的鋁說(shuo)明(ming)已被氧化。

第(di)三(san)、在購買(mai)電線(xian)時應(ying)注(zhu)意查(cha)看(kan)質量(liang)合格(ge)證書(shu)。如果電線(xian)的質量(liang)合格(ge)，那么其電線(xian)質量(liang)應(ying)該也(ye)受過檢驗，不會有太大的問題。
