不(bu)合(he)格電(dian)線(xian)電(dian)纜(lan)的危害(hai)

電(dian)線(xian)電(dian)纜是用于傳輸電(dian)力、傳輸信(xin)息和實現電(dian)磁能量轉換(huan)的(de)一大類電(dian)工產(chan)品。在抽查(cha)過程中，發現了大量的(de)不合格(ge)產(chan)品，這(zhe)些劣(lie)質(zhi)產(chan)品給電(dian)力系統正常(chang)運行埋下諸多隱患(huan)。

1、標(biao)(biao)志(zhi)不合(he)格(ge)的電線(xian)電纜(lan)。標(biao)(biao)志(zhi)是電線(xian)電纜(lan)使用識別產品基(ji)本信息的主(zhu)要途徑，根據(ju)標(biao)(biao)準(zhun)(zhun)規(gui)定標(biao)(biao)志(zhi)的主(zhu)要內容是：產品型號(hao)、規(gui)格(ge)、標(biao)(biao)準(zhun)(zhun)號(hao)、廠名、產地等在一定的標(biao)(biao)示間距內，當標(biao)(biao)志(zhi)不合(he)格(ge)時(shi)，會造成(cheng)施(shi)工人員識別錯(cuo)誤，嚴重時(shi)會引發電氣事故。

2、結構尺(chi)寸不合格的電(dian)(dian)線(xian)電(dian)(dian)纜(lan)。結構尺(chi)寸的主要問(wen)題是護套(tao)厚度(du)，絕緣(yuan)(yuan)厚度(du)，當電(dian)(dian)纜(lan)的護套(tao)和絕緣(yuan)(yuan)厚度(du)不達標(biao)時，致使電(dian)(dian)線(xian)電(dian)(dian)纜(lan)耐電(dian)(dian)氣強(qiang)度(du)會嚴(yan)重降低(di)，導(dao)致電(dian)(dian)線(xian)電(dian)(dian)纜(lan)的使用壽(shou)命縮短(duan)，嚴(yan)重時可導(dao)致電(dian)(dian)線(xian)電(dian)(dian)纜(lan)被(bei)擊穿，絕緣(yuan)(yuan)（護套(tao)）層起不到正常保護作(zuo)用，從而發生電(dian)(dian)氣短(duan)路和火(huo)災等現象。

3、護(hu)套式絕(jue)緣(yuan)老化(hua)前的(de)抗張強(qiang)度(du)、伸(shen)長(chang)率合格的(de)電線電纜。絕(jue)緣(yuan)護(hu)套老化(hua)前的(de)抗張強(qiang)度(du)、伸(shen)長(chang)率不合格直(zhi)接大(da)大(da)縮短電線電纜的(de)工(gong)作用壽命，而(er)且(qie)在施工(gong)或(huo)在長(chang)時間(jian)通電且(qie)溫(wen)度(du)較高(gao)的(de)環境中，極(ji)易出(chu)現絕(jue)緣(yuan)體(ti)(ti)斷裂，致(zhi)使帶電導體(ti)(ti)裸露，發(fa)生(sheng)能觸電式短路危險(xian)。其不合格的(de)主(zhu)要(yao)原因是(shi)使用了再(zai)生(sheng)料生(sheng)產，以降低(di)產品成本，二是(shi)不具備生(sheng)產資格小型(xing)企業(ye)。

4、導(dao)體(ti)電(dian)(dian)阻不(bu)合(he)格的(de)電(dian)(dian)線。導(dao)體(ti)電(dian)(dian)阻主要(yao)是考核(he)電(dian)(dian)線電(dian)(dian)纜的(de)導(dao)體(ti)材(cai)料以及截面(mian)是否符合(he)的(de)重要(yao)指標(biao)。當導(dao)體(ti)電(dian)(dian)阻超標(biao)時(shi)，就增大了電(dian)(dian)流在線路上通過時(shi)的(de)損耗，加(jia)劇(ju)了電(dian)(dian)線電(dian)(dian)纜的(de)發(fa)熱。導(dao)體(ti)電(dian)(dian)阻不(bu)合(he)格的(de)原因，主要(yao)進企業(ye)為(wei)了降(jiang)(jiang)低成(cheng)本，將占原材(cai)料成(cheng)本80%的(de)銅(tong)材(cai)縮水，要(yao)么降(jiang)(jiang)低導(dao)體(ti)的(de)截面(mian)積，要(yao)么使用(yong)含雜質(zhi)過高的(de)再生銅(tong)，這樣致使電(dian)(dian)線電(dian)(dian)纜的(de)導(dao)體(ti)電(dian)(dian)阻嚴重超標(biao)，在使用(yong)過程中(zhong)除易引發(fa)火災，還(huan)會(hui)加(jia)速(su)包覆在電(dian)(dian)線外(wai)的(de)絕緣層的(de)老化。

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

第(di)一、要(yao)觀察電線的(de)(de)外觀。合格產(chan)品的(de)(de)絕緣（護(hu)套）層柔軟、有韌性和伸縮性、表面層緊密、光(guang)滑(hua)、無粗糙感(gan)。如果包(bao)裹電線的(de)(de)塑(su)料很容易被(bei)剝去，則(ze)存在塑(su)料強度不夠的(de)(de)問題。

第二、要看電線的截面(mian)(mian)。合格產品的銅(tong)芯或(huo)鋁芯表(biao)面(mian)(mian)應該具有(you)金屬光(guang)澤，表(biao)面(mian)(mian)發黑的銅(tong)或(huo)表(biao)面(mian)(mian)發白的鋁說(shuo)明已(yi)被(bei)氧(yang)化。

第三、在購買電(dian)線(xian)時應注(zhu)意查看質(zhi)量合格證書。如果電(dian)線(xian)的質(zhi)量合格，那么其電(dian)線(xian)質(zhi)量應該也受(shou)過檢驗(yan)，不會有太大的問題(ti)。
