不(bu)合格(ge)電線電纜(lan)的危害

電(dian)線電(dian)纜是用于傳輸(shu)電(dian)力(li)、傳輸(shu)信息和實現電(dian)磁能量(liang)轉換的(de)一大(da)類電(dian)工產(chan)品。在抽查過程中，發現了大(da)量(liang)的(de)不合格產(chan)品，這些(xie)劣質(zhi)產(chan)品給電(dian)力(li)系統正常運行(xing)埋下諸多(duo)隱患。

1、標(biao)志(zhi)不合格(ge)的(de)(de)電線電纜(lan)(lan)。標(biao)志(zhi)是(shi)電線電纜(lan)(lan)使用識別產(chan)品基本信息的(de)(de)主要途徑(jing)，根(gen)據標(biao)準規定標(biao)志(zhi)的(de)(de)主要內容是(shi)：產(chan)品型號(hao)、規格(ge)、標(biao)準號(hao)、廠名、產(chan)地等在(zai)一定的(de)(de)標(biao)示間距內，當標(biao)志(zhi)不合格(ge)時(shi)，會造成(cheng)施工人(ren)員識別錯(cuo)誤，嚴重時(shi)會引發(fa)電氣事故。

2、結構(gou)(gou)尺寸不(bu)(bu)合格的(de)(de)電(dian)線(xian)(xian)電(dian)纜(lan)(lan)。結構(gou)(gou)尺寸的(de)(de)主要(yao)問題是(shi)護套(tao)厚度(du)(du)，絕緣厚度(du)(du)，當電(dian)纜(lan)(lan)的(de)(de)護套(tao)和絕緣厚度(du)(du)不(bu)(bu)達(da)標時，致(zhi)使電(dian)線(xian)(xian)電(dian)纜(lan)(lan)耐(nai)電(dian)氣(qi)強(qiang)度(du)(du)會嚴(yan)重降低，導(dao)致(zhi)電(dian)線(xian)(xian)電(dian)纜(lan)(lan)的(de)(de)使用(yong)壽命縮短(duan)，嚴(yan)重時可導(dao)致(zhi)電(dian)線(xian)(xian)電(dian)纜(lan)(lan)被擊穿(chuan)，絕緣（護套(tao)）層起不(bu)(bu)到正常保護作用(yong)，從而發生電(dian)氣(qi)短(duan)路和火災等現象。

3、護(hu)套(tao)式絕(jue)緣老化前的(de)抗張(zhang)強度、伸(shen)長(chang)(chang)率合(he)格(ge)(ge)的(de)電(dian)線電(dian)纜(lan)。絕(jue)緣護(hu)套(tao)老化前的(de)抗張(zhang)強度、伸(shen)長(chang)(chang)率不(bu)(bu)合(he)格(ge)(ge)直接大大縮短電(dian)線電(dian)纜(lan)的(de)工作(zuo)用(yong)壽命，而且在施工或在長(chang)(chang)時(shi)間(jian)通(tong)電(dian)且溫度較高(gao)的(de)環境中，極易出現絕(jue)緣體(ti)斷裂(lie)，致(zhi)使(shi)帶電(dian)導體(ti)裸露，發生能觸(chu)電(dian)式短路(lu)危險(xian)。其(qi)不(bu)(bu)合(he)格(ge)(ge)的(de)主要原(yuan)因是使(shi)用(yong)了再生料(liao)生產，以降低(di)產品成本(ben)，二是不(bu)(bu)具備生產資(zi)格(ge)(ge)小(xiao)型(xing)企業。

4、導(dao)(dao)(dao)體(ti)電(dian)(dian)(dian)阻(zu)不(bu)合(he)格的(de)電(dian)(dian)(dian)線(xian)。導(dao)(dao)(dao)體(ti)電(dian)(dian)(dian)阻(zu)主要是考(kao)核電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜的(de)導(dao)(dao)(dao)體(ti)材料以及截面是否符合(he)的(de)重要指(zhi)標。當導(dao)(dao)(dao)體(ti)電(dian)(dian)(dian)阻(zu)超(chao)標時(shi)，就增(zeng)大(da)了(le)(le)電(dian)(dian)(dian)流在(zai)線(xian)路上通過(guo)時(shi)的(de)損耗，加(jia)劇(ju)了(le)(le)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜的(de)發熱。導(dao)(dao)(dao)體(ti)電(dian)(dian)(dian)阻(zu)不(bu)合(he)格的(de)原(yuan)因，主要進企業為了(le)(le)降(jiang)低成本(ben)，將占(zhan)原(yuan)材料成本(ben)80%的(de)銅材縮水(shui)，要么(me)降(jiang)低導(dao)(dao)(dao)體(ti)的(de)截面積，要么(me)使(shi)用含(han)雜質(zhi)過(guo)高的(de)再生銅，這(zhe)樣致使(shi)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜的(de)導(dao)(dao)(dao)體(ti)電(dian)(dian)(dian)阻(zu)嚴重超(chao)標，在(zai)使(shi)用過(guo)程中除易引發火(huo)災，還會(hui)加(jia)速包(bao)覆在(zai)電(dian)(dian)(dian)線(xian)外的(de)絕緣層(ceng)的(de)老化。

在購(gou)買(mai)電線(xian)電纜的過程中，消費者應注意以(yi)下幾個(ge)事

第一、要(yao)觀察電線(xian)的外觀。合格產品的絕緣（護套）層(ceng)柔軟、有韌性和(he)伸縮性、表面層(ceng)緊密(mi)、光滑(hua)、無粗糙(cao)感。如(ru)果包裹電線(xian)的塑(su)料很容易被剝去，則存在塑(su)料強度不(bu)夠的問題。

第(di)二、要看電線的截面(mian)(mian)(mian)。合格產品的銅芯(xin)或鋁芯(xin)表(biao)(biao)面(mian)(mian)(mian)應該(gai)具有金(jin)屬光澤，表(biao)(biao)面(mian)(mian)(mian)發黑的銅或表(biao)(biao)面(mian)(mian)(mian)發白的鋁說明已被氧化。

第三(san)、在購買電線(xian)時(shi)應注意查看質量合格(ge)證書。如果電線(xian)的質量合格(ge)，那么其電線(xian)質量應該也受過(guo)檢驗，不會有太大的問題。
