不(bu)合格電(dian)線電(dian)纜(lan)的危害

電(dian)(dian)線(xian)電(dian)(dian)纜是(shi)用于(yu)傳(chuan)輸電(dian)(dian)力、傳(chuan)輸信息(xi)和實現電(dian)(dian)磁能量轉換(huan)的(de)一大類(lei)電(dian)(dian)工產(chan)品(pin)(pin)。在(zai)抽查(cha)過(guo)程(cheng)中，發現了大量的(de)不合格產(chan)品(pin)(pin)，這些(xie)劣質產(chan)品(pin)(pin)給電(dian)(dian)力系(xi)統正常運行埋下諸多隱患。

1、標(biao)志不合格(ge)(ge)的(de)電(dian)線電(dian)纜。標(biao)志是電(dian)線電(dian)纜使(shi)用識別(bie)產品基本信息的(de)主要途(tu)徑(jing)，根據(ju)標(biao)準(zhun)規定(ding)標(biao)志的(de)主要內容是：產品型號、規格(ge)(ge)、標(biao)準(zhun)號、廠名、產地等在(zai)一定(ding)的(de)標(biao)示(shi)間距內，當標(biao)志不合格(ge)(ge)時，會(hui)造成(cheng)施工人(ren)員識別(bie)錯誤，嚴重時會(hui)引發(fa)電(dian)氣事故。

2、結構尺(chi)寸不(bu)合格的(de)(de)電(dian)(dian)線電(dian)(dian)纜(lan)(lan)(lan)。結構尺(chi)寸的(de)(de)主要問題是護(hu)套(tao)厚(hou)度，絕緣厚(hou)度，當電(dian)(dian)纜(lan)(lan)(lan)的(de)(de)護(hu)套(tao)和絕緣厚(hou)度不(bu)達(da)標時，致(zhi)(zhi)使電(dian)(dian)線電(dian)(dian)纜(lan)(lan)(lan)耐電(dian)(dian)氣強度會嚴重降低，導致(zhi)(zhi)電(dian)(dian)線電(dian)(dian)纜(lan)(lan)(lan)的(de)(de)使用(yong)壽命縮短，嚴重時可導致(zhi)(zhi)電(dian)(dian)線電(dian)(dian)纜(lan)(lan)(lan)被(bei)擊穿，絕緣（護(hu)套(tao)）層起(qi)不(bu)到正常保護(hu)作用(yong)，從而發生電(dian)(dian)氣短路和火災等現象。

3、護套式絕緣老(lao)化前的(de)(de)(de)抗張強(qiang)度(du)、伸長(chang)率合(he)格(ge)(ge)的(de)(de)(de)電(dian)(dian)線電(dian)(dian)纜。絕緣護套老(lao)化前的(de)(de)(de)抗張強(qiang)度(du)、伸長(chang)率不合(he)格(ge)(ge)直接大(da)大(da)縮短電(dian)(dian)線電(dian)(dian)纜的(de)(de)(de)工作用壽命，而且(qie)在施工或在長(chang)時間(jian)通電(dian)(dian)且(qie)溫度(du)較高(gao)的(de)(de)(de)環境中，極易出現絕緣體(ti)斷裂(lie)，致(zhi)使(shi)帶電(dian)(dian)導體(ti)裸露(lu)，發生能觸(chu)電(dian)(dian)式短路危險。其不合(he)格(ge)(ge)的(de)(de)(de)主要原因是使(shi)用了再生料(liao)生產(chan)，以降低產(chan)品成本，二是不具備生產(chan)資格(ge)(ge)小(xiao)型企業。

4、導(dao)體(ti)電阻不合(he)(he)格的(de)(de)(de)(de)電線(xian)。導(dao)體(ti)電阻主(zhu)要是(shi)考核電線(xian)電纜(lan)的(de)(de)(de)(de)導(dao)體(ti)材料以(yi)及截(jie)面(mian)是(shi)否符合(he)(he)的(de)(de)(de)(de)重要指(zhi)標(biao)。當導(dao)體(ti)電阻超(chao)標(biao)時，就增大了電流在(zai)線(xian)路上通過時的(de)(de)(de)(de)損耗，加劇了電線(xian)電纜(lan)的(de)(de)(de)(de)發熱(re)。導(dao)體(ti)電阻不合(he)(he)格的(de)(de)(de)(de)原因，主(zhu)要進企業為了降低成本，將占原材料成本80%的(de)(de)(de)(de)銅材縮(suo)水，要么降低導(dao)體(ti)的(de)(de)(de)(de)截(jie)面(mian)積，要么使(shi)用含雜質過高的(de)(de)(de)(de)再生銅，這樣致使(shi)電線(xian)電纜(lan)的(de)(de)(de)(de)導(dao)體(ti)電阻嚴(yan)重超(chao)標(biao)，在(zai)使(shi)用過程(cheng)中除易引發火(huo)災，還會(hui)加速包(bao)覆(fu)在(zai)電線(xian)外(wai)的(de)(de)(de)(de)絕緣層的(de)(de)(de)(de)老(lao)化。

在購買電線電纜(lan)的過程(cheng)中，消(xiao)費者應注意以下幾(ji)個事

第一、要(yao)觀(guan)察電線的(de)外(wai)觀(guan)。合格產品的(de)絕緣（護套(tao)）層柔軟、有韌性(xing)和伸縮性(xing)、表面層緊密、光(guang)滑、無(wu)粗糙(cao)感。如果(guo)包裹電線的(de)塑料(liao)很(hen)容易(yi)被剝去，則存在塑料(liao)強度不夠(gou)的(de)問題。

第(di)二、要看電(dian)線的截面(mian)。合格產品(pin)的銅芯或鋁(lv)芯表(biao)面(mian)應該具有金屬光澤，表(biao)面(mian)發黑(hei)的銅或表(biao)面(mian)發白的鋁(lv)說明已被氧化。

第三、在(zai)購(gou)買電線(xian)時應注意查看質量(liang)合(he)格證書。如果電線(xian)的質量(liang)合(he)格，那么其電線(xian)質量(liang)應該也(ye)受(shou)過檢驗，不會有太大的問題。
