不(bu)合(he)格電(dian)線電(dian)纜的危害

電(dian)(dian)線電(dian)(dian)纜是用(yong)于傳輸電(dian)(dian)力(li)、傳輸信息和實現電(dian)(dian)磁能量轉換的(de)一大(da)類電(dian)(dian)工產品(pin)。在抽查過程中(zhong)，發現了(le)大(da)量的(de)不合格產品(pin)，這些劣質產品(pin)給電(dian)(dian)力(li)系統(tong)正常(chang)運(yun)行埋下諸多(duo)隱(yin)患。

1、標(biao)(biao)志不合格(ge)的(de)(de)電線電纜。標(biao)(biao)志是(shi)電線電纜使用識別(bie)產(chan)品基本信息的(de)(de)主要途徑，根據標(biao)(biao)準規(gui)定(ding)標(biao)(biao)志的(de)(de)主要內容是(shi)：產(chan)品型號、規(gui)格(ge)、標(biao)(biao)準號、廠名(ming)、產(chan)地等在一(yi)定(ding)的(de)(de)標(biao)(biao)示間距內，當標(biao)(biao)志不合格(ge)時(shi)，會造成施工人員識別(bie)錯誤，嚴重時(shi)會引發電氣事故。

2、結構尺(chi)寸不(bu)合格的(de)電(dian)(dian)線(xian)電(dian)(dian)纜(lan)(lan)。結構尺(chi)寸的(de)主要問題是護(hu)(hu)套厚(hou)度，絕(jue)緣厚(hou)度，當(dang)電(dian)(dian)纜(lan)(lan)的(de)護(hu)(hu)套和絕(jue)緣厚(hou)度不(bu)達標時(shi)，致(zhi)(zhi)使(shi)電(dian)(dian)線(xian)電(dian)(dian)纜(lan)(lan)耐電(dian)(dian)氣強(qiang)度會(hui)嚴重(zhong)降低，導致(zhi)(zhi)電(dian)(dian)線(xian)電(dian)(dian)纜(lan)(lan)的(de)使(shi)用壽命(ming)縮(suo)短，嚴重(zhong)時(shi)可導致(zhi)(zhi)電(dian)(dian)線(xian)電(dian)(dian)纜(lan)(lan)被擊(ji)穿，絕(jue)緣（護(hu)(hu)套）層起不(bu)到正常保(bao)護(hu)(hu)作用，從而發生電(dian)(dian)氣短路(lu)和火災等現象。

3、護(hu)套(tao)式絕(jue)緣(yuan)老化(hua)前(qian)的抗張(zhang)強(qiang)度(du)、伸長(chang)率(lv)合格的電線電纜(lan)。絕(jue)緣(yuan)護(hu)套(tao)老化(hua)前(qian)的抗張(zhang)強(qiang)度(du)、伸長(chang)率(lv)不合格直接大大縮短電線電纜(lan)的工作(zuo)用壽命，而且在施(shi)工或在長(chang)時(shi)間通(tong)電且溫度(du)較高的環境中，極易出現絕(jue)緣(yuan)體斷(duan)裂，致(zhi)使(shi)帶電導體裸露，發(fa)生能觸(chu)電式短路(lu)危險。其不合格的主要原因是使(shi)用了再生料生產，以降低產品成本，二(er)是不具備生產資格小(xiao)型企業(ye)。

4、導(dao)(dao)體電(dian)(dian)阻(zu)不(bu)合(he)格的(de)電(dian)(dian)線(xian)(xian)。導(dao)(dao)體電(dian)(dian)阻(zu)主要是(shi)考核電(dian)(dian)線(xian)(xian)電(dian)(dian)纜的(de)導(dao)(dao)體材料以及截(jie)面是(shi)否(fou)符(fu)合(he)的(de)重要指標。當導(dao)(dao)體電(dian)(dian)阻(zu)超標時(shi)，就增大了電(dian)(dian)流在線(xian)(xian)路上通過時(shi)的(de)損耗，加劇了電(dian)(dian)線(xian)(xian)電(dian)(dian)纜的(de)發(fa)(fa)熱。導(dao)(dao)體電(dian)(dian)阻(zu)不(bu)合(he)格的(de)原因，主要進企業為(wei)了降低成本，將占原材料成本80%的(de)銅材縮水，要么降低導(dao)(dao)體的(de)截(jie)面積，要么使(shi)用含雜質過高的(de)再生銅，這樣致使(shi)電(dian)(dian)線(xian)(xian)電(dian)(dian)纜的(de)導(dao)(dao)體電(dian)(dian)阻(zu)嚴重超標，在使(shi)用過程(cheng)中(zhong)除易(yi)引(yin)發(fa)(fa)火災，還(huan)會加速(su)包覆在電(dian)(dian)線(xian)(xian)外的(de)絕緣層(ceng)的(de)老化。

在購(gou)買電(dian)線電(dian)纜的過程中，消費者(zhe)應注意(yi)以下(xia)幾個事

第一、要(yao)觀察(cha)電線的(de)(de)外觀。合格產(chan)品的(de)(de)絕緣(yuan)（護套）層柔(rou)軟、有(you)韌性和伸縮性、表面層緊密、光(guang)滑、無粗(cu)糙感(gan)。如果包(bao)裹(guo)電線的(de)(de)塑(su)料很容(rong)易被剝去(qu)，則存在塑(su)料強(qiang)度不夠的(de)(de)問題(ti)。

第二、要看電(dian)線的截面(mian)。合(he)格產品的銅芯或(huo)鋁(lv)芯表(biao)(biao)面(mian)應該具有金屬光澤，表(biao)(biao)面(mian)發(fa)黑的銅或(huo)表(biao)(biao)面(mian)發(fa)白(bai)的鋁(lv)說明已被氧化。

第(di)三、在(zai)購買電線時應(ying)注意(yi)查(cha)看(kan)質量(liang)合(he)(he)格證書。如果電線的質量(liang)合(he)(he)格，那么(me)其電線質量(liang)應(ying)該也受(shou)過檢驗，不會有太大的問(wen)題。
