不合格(ge)電線電纜的(de)危害(hai)

電線電纜是(shi)用于傳(chuan)(chuan)輸電力、傳(chuan)(chuan)輸信息和(he)實現(xian)電磁能量轉換的一大(da)類電工(gong)產(chan)品(pin)。在抽查過程中(zhong)，發(fa)現(xian)了大(da)量的不合格(ge)產(chan)品(pin)，這些劣質(zhi)產(chan)品(pin)給電力系(xi)統正常運行埋下(xia)諸多(duo)隱患。

1、標(biao)(biao)志不合(he)(he)格(ge)(ge)的(de)電線電纜(lan)。標(biao)(biao)志是(shi)電線電纜(lan)使用識別(bie)產(chan)品基(ji)本信息的(de)主(zhu)要途徑，根據標(biao)(biao)準(zhun)(zhun)規定標(biao)(biao)志的(de)主(zhu)要內(nei)容是(shi)：產(chan)品型號、規格(ge)(ge)、標(biao)(biao)準(zhun)(zhun)號、廠名(ming)、產(chan)地等(deng)在一定的(de)標(biao)(biao)示間距內(nei)，當標(biao)(biao)志不合(he)(he)格(ge)(ge)時(shi)，會(hui)造成施工人員識別(bie)錯(cuo)誤，嚴重時(shi)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)(lan)。結構尺寸的主(zhu)要問題是(shi)護(hu)套(tao)(tao)厚度(du)，絕緣(yuan)厚度(du)，當電(dian)(dian)(dian)纜(lan)(lan)的護(hu)套(tao)(tao)和(he)絕緣(yuan)厚度(du)不(bu)達標時(shi)，致(zhi)使電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)(lan)耐電(dian)(dian)(dian)氣強度(du)會嚴重(zhong)降低(di)，導致(zhi)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)(lan)的使用壽(shou)命縮短(duan)，嚴重(zhong)時(shi)可導致(zhi)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)(lan)被擊穿，絕緣(yuan)（護(hu)套(tao)(tao)）層起不(bu)到正常保護(hu)作用，從而發生電(dian)(dian)(dian)氣短(duan)路(lu)和(he)火災等現象(xiang)。

3、護(hu)套(tao)式絕緣(yuan)老(lao)化前(qian)的(de)抗張(zhang)強(qiang)度、伸(shen)長(chang)率合格的(de)電線(xian)電纜。絕緣(yuan)護(hu)套(tao)老(lao)化前(qian)的(de)抗張(zhang)強(qiang)度、伸(shen)長(chang)率不合格直接大大縮短電線(xian)電纜的(de)工(gong)作用(yong)壽命，而且在施(shi)工(gong)或在長(chang)時間(jian)通電且溫(wen)度較高(gao)的(de)環境中，極易(yi)出現絕緣(yuan)體斷裂，致使帶電導體裸露(lu)，發生能觸電式短路危(wei)險(xian)。其不合格的(de)主要原因(yin)是(shi)使用(yong)了再生料生產，以降低產品成(cheng)本(ben)，二是(shi)不具備生產資格小(xiao)型企業。

4、導(dao)體(ti)電(dian)(dian)(dian)阻(zu)(zu)不合(he)格的(de)(de)(de)電(dian)(dian)(dian)線(xian)。導(dao)體(ti)電(dian)(dian)(dian)阻(zu)(zu)主要(yao)是考核電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)的(de)(de)(de)導(dao)體(ti)材料(liao)(liao)以(yi)及截面(mian)是否符合(he)的(de)(de)(de)重要(yao)指(zhi)標。當導(dao)體(ti)電(dian)(dian)(dian)阻(zu)(zu)超標時，就增大了(le)電(dian)(dian)(dian)流在線(xian)路上通過(guo)時的(de)(de)(de)損耗，加(jia)劇了(le)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)的(de)(de)(de)發(fa)熱。導(dao)體(ti)電(dian)(dian)(dian)阻(zu)(zu)不合(he)格的(de)(de)(de)原因，主要(yao)進(jin)企業為了(le)降低成(cheng)本(ben)，將占原材料(liao)(liao)成(cheng)本(ben)80%的(de)(de)(de)銅材縮水(shui)，要(yao)么降低導(dao)體(ti)的(de)(de)(de)截面(mian)積，要(yao)么使(shi)用含雜質過(guo)高的(de)(de)(de)再生銅，這樣(yang)致使(shi)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)的(de)(de)(de)導(dao)體(ti)電(dian)(dian)(dian)阻(zu)(zu)嚴重超標，在使(shi)用過(guo)程中除易(yi)引發(fa)火災，還會加(jia)速包覆在電(dian)(dian)(dian)線(xian)外的(de)(de)(de)絕緣(yuan)層的(de)(de)(de)老化。

在購買電線電纜的過(guo)程中，消費者(zhe)應注(zhu)意以下幾(ji)個(ge)事

第一、要觀察電線的(de)外觀。合格產品的(de)絕緣（護套）層柔軟、有(you)韌性和伸縮(suo)性、表面(mian)層緊(jin)密、光(guang)滑、無粗糙感。如果包裹電線的(de)塑料(liao)(liao)很容易被剝去，則(ze)存在塑料(liao)(liao)強(qiang)度(du)不夠的(de)問題。

第(di)二、要看電線的(de)截面。合(he)格產品的(de)銅芯或鋁芯表面應(ying)該(gai)具有金屬光澤，表面發(fa)黑的(de)銅或表面發(fa)白的(de)鋁說明已被氧化。

第三、在(zai)購買電線時應(ying)注意查看質(zhi)量(liang)合(he)格證書。如果電線的質(zhi)量(liang)合(he)格，那么其電線質(zhi)量(liang)應(ying)該也受過(guo)檢(jian)驗(yan)，不會有太大的問題。
