不合格電線電纜的危(wei)害(hai)

電(dian)線電(dian)纜是用于(yu)傳輸(shu)電(dian)力(li)、傳輸(shu)信息和實現電(dian)磁能量轉換的(de)一大(da)類電(dian)工(gong)產(chan)品(pin)(pin)。在抽(chou)查過程中(zhong)，發現了大(da)量的(de)不合格產(chan)品(pin)(pin)，這些劣質產(chan)品(pin)(pin)給電(dian)力(li)系統(tong)正常運行埋下諸多隱患(huan)。

1、標(biao)(biao)(biao)志(zhi)(zhi)不合格(ge)(ge)的(de)電(dian)線電(dian)纜(lan)。標(biao)(biao)(biao)志(zhi)(zhi)是電(dian)線電(dian)纜(lan)使用識別(bie)產品(pin)基本信息的(de)主要途徑，根(gen)據標(biao)(biao)(biao)準規(gui)定標(biao)(biao)(biao)志(zhi)(zhi)的(de)主要內(nei)容是：產品(pin)型號、規(gui)格(ge)(ge)、標(biao)(biao)(biao)準號、廠名(ming)、產地等在一定的(de)標(biao)(biao)(biao)示(shi)間距內(nei)，當標(biao)(biao)(biao)志(zhi)(zhi)不合格(ge)(ge)時(shi)(shi)，會造成施工人(ren)員識別(bie)錯誤，嚴(yan)重(zhong)時(shi)(shi)會引(yin)發電(dian)氣事故。

2、結構尺寸(cun)不(bu)合格的(de)(de)電(dian)(dian)線(xian)電(dian)(dian)纜(lan)。結構尺寸(cun)的(de)(de)主(zhu)要問題是護(hu)套厚(hou)度(du)(du)，絕緣(yuan)厚(hou)度(du)(du)，當電(dian)(dian)纜(lan)的(de)(de)護(hu)套和絕緣(yuan)厚(hou)度(du)(du)不(bu)達標(biao)時，致使電(dian)(dian)線(xian)電(dian)(dian)纜(lan)耐電(dian)(dian)氣強度(du)(du)會嚴重(zhong)降低，導致電(dian)(dian)線(xian)電(dian)(dian)纜(lan)的(de)(de)使用(yong)壽(shou)命縮(suo)短(duan)，嚴重(zhong)時可(ke)導致電(dian)(dian)線(xian)電(dian)(dian)纜(lan)被擊穿，絕緣(yuan)（護(hu)套）層起不(bu)到正常保護(hu)作用(yong)，從而發生電(dian)(dian)氣短(duan)路和火災等現(xian)象。

3、護套(tao)式絕(jue)緣(yuan)老化前(qian)的(de)抗張(zhang)強度、伸長(chang)率(lv)合(he)格(ge)的(de)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜。絕(jue)緣(yuan)護套(tao)老化前(qian)的(de)抗張(zhang)強度、伸長(chang)率(lv)不合(he)格(ge)直(zhi)接大(da)大(da)縮短(duan)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜的(de)工作(zuo)用壽命，而且在施工或在長(chang)時(shi)間通(tong)電(dian)(dian)(dian)且溫度較高(gao)的(de)環境中，極(ji)易出現絕(jue)緣(yuan)體(ti)斷裂(lie)，致使帶電(dian)(dian)(dian)導(dao)體(ti)裸露(lu)，發生能觸電(dian)(dian)(dian)式短(duan)路危險。其不合(he)格(ge)的(de)主要(yao)原因(yin)是使用了再生料生產，以降低產品成本，二是不具備生產資格(ge)小型企(qi)業。

4、導(dao)體(ti)電(dian)(dian)阻(zu)不(bu)合(he)格的(de)(de)(de)(de)電(dian)(dian)線(xian)。導(dao)體(ti)電(dian)(dian)阻(zu)主(zhu)要是考核(he)電(dian)(dian)線(xian)電(dian)(dian)纜(lan)(lan)(lan)的(de)(de)(de)(de)導(dao)體(ti)材料以(yi)及(ji)截面(mian)是否符合(he)的(de)(de)(de)(de)重要指標(biao)。當導(dao)體(ti)電(dian)(dian)阻(zu)超標(biao)時(shi)，就增大了電(dian)(dian)流在線(xian)路(lu)上通過(guo)(guo)時(shi)的(de)(de)(de)(de)損(sun)耗(hao)，加劇(ju)了電(dian)(dian)線(xian)電(dian)(dian)纜(lan)(lan)(lan)的(de)(de)(de)(de)發熱。導(dao)體(ti)電(dian)(dian)阻(zu)不(bu)合(he)格的(de)(de)(de)(de)原因，主(zhu)要進企業為了降低(di)成本(ben)，將占原材料成本(ben)80%的(de)(de)(de)(de)銅(tong)材縮水，要么(me)降低(di)導(dao)體(ti)的(de)(de)(de)(de)截面(mian)積，要么(me)使用(yong)含雜質過(guo)(guo)高的(de)(de)(de)(de)再生銅(tong)，這樣(yang)致使電(dian)(dian)線(xian)電(dian)(dian)纜(lan)(lan)(lan)的(de)(de)(de)(de)導(dao)體(ti)電(dian)(dian)阻(zu)嚴重超標(biao)，在使用(yong)過(guo)(guo)程中除易引發火災，還會加速包覆(fu)在電(dian)(dian)線(xian)外(wai)的(de)(de)(de)(de)絕緣層的(de)(de)(de)(de)老化(hua)。

在購買(mai)電線電纜的(de)過程中，消(xiao)費者(zhe)應(ying)注意以下幾個事(shi)

第(di)一、要觀察電線的(de)外觀。合格產品(pin)的(de)絕(jue)緣(yuan)（護套）層柔軟、有韌性和伸縮性、表面層緊(jin)密、光(guang)滑、無粗糙感(gan)。如(ru)果包裹(guo)電線的(de)塑料很容易被剝(bo)去，則存在塑料強(qiang)度不夠的(de)問(wen)題。

第二、要(yao)看電線(xian)的截面(mian)。合格產品(pin)的銅(tong)芯或鋁(lv)(lv)芯表面(mian)應(ying)該(gai)具有金(jin)屬光(guang)澤，表面(mian)發黑的銅(tong)或表面(mian)發白的鋁(lv)(lv)說明已被氧化。

第三、在(zai)購(gou)買(mai)電(dian)線時應注(zhu)意查(cha)看質(zhi)量(liang)合格證書。如果電(dian)線的質(zhi)量(liang)合格，那么其電(dian)線質(zhi)量(liang)應該也(ye)受過檢驗，不會有太大的問題。
