不合格電線電纜(lan)的(de)危害

電(dian)(dian)線電(dian)(dian)纜是用于傳(chuan)(chuan)輸(shu)電(dian)(dian)力、傳(chuan)(chuan)輸(shu)信息(xi)和實(shi)現電(dian)(dian)磁能(neng)量(liang)轉換的一大類電(dian)(dian)工產品(pin)。在(zai)抽(chou)查過程中，發(fa)現了大量(liang)的不合格產品(pin)，這些(xie)劣質(zhi)產品(pin)給電(dian)(dian)力系(xi)統正常(chang)運(yun)行埋下(xia)諸多隱患。

1、標(biao)志(zhi)(zhi)不合格(ge)的(de)電(dian)線電(dian)纜。標(biao)志(zhi)(zhi)是電(dian)線電(dian)纜使(shi)用識(shi)別產(chan)品基本信息的(de)主(zhu)要(yao)途徑，根據標(biao)準規定標(biao)志(zhi)(zhi)的(de)主(zhu)要(yao)內(nei)容(rong)是：產(chan)品型號、規格(ge)、標(biao)準號、廠名、產(chan)地等在一定的(de)標(biao)示間距內(nei)，當(dang)標(biao)志(zhi)(zhi)不合格(ge)時(shi)，會造(zao)成施工人(ren)員識(shi)別錯誤，嚴重時(shi)會引發電(dian)氣事故(gu)。

2、結構尺寸不合格(ge)的(de)電(dian)線(xian)電(dian)纜。結構尺寸的(de)主要(yao)問(wen)題是護(hu)套厚度，絕緣厚度，當電(dian)纜的(de)護(hu)套和(he)絕緣厚度不達標時，致使(shi)電(dian)線(xian)電(dian)纜耐電(dian)氣(qi)強(qiang)度會嚴重降(jiang)低(di)，導致電(dian)線(xian)電(dian)纜的(de)使(shi)用(yong)(yong)壽命縮短，嚴重時可導致電(dian)線(xian)電(dian)纜被擊穿，絕緣（護(hu)套）層起不到正常保護(hu)作用(yong)(yong)，從而(er)發生電(dian)氣(qi)短路(lu)和(he)火災等(deng)現象。

3、護(hu)套式絕緣老(lao)化前(qian)的(de)抗(kang)張(zhang)(zhang)強度、伸(shen)長率(lv)合(he)格的(de)電(dian)線電(dian)纜。絕緣護(hu)套老(lao)化前(qian)的(de)抗(kang)張(zhang)(zhang)強度、伸(shen)長率(lv)不合(he)格直(zhi)接(jie)大(da)大(da)縮(suo)短(duan)電(dian)線電(dian)纜的(de)工作(zuo)用壽命，而且在(zai)施工或在(zai)長時(shi)間通電(dian)且溫度較高的(de)環境中，極易出(chu)現(xian)絕緣體(ti)斷裂，致使帶電(dian)導體(ti)裸(luo)露(lu)，發生(sheng)(sheng)能(neng)觸電(dian)式短(duan)路危險。其不合(he)格的(de)主要原因是使用了再(zai)生(sheng)(sheng)料生(sheng)(sheng)產，以降低產品成(cheng)本，二是不具備生(sheng)(sheng)產資格小型企業。

4、導體(ti)(ti)電(dian)(dian)阻不合(he)格的(de)(de)(de)(de)(de)(de)電(dian)(dian)線(xian)(xian)。導體(ti)(ti)電(dian)(dian)阻主要(yao)是考核電(dian)(dian)線(xian)(xian)電(dian)(dian)纜的(de)(de)(de)(de)(de)(de)導體(ti)(ti)材(cai)料(liao)以及截(jie)(jie)面是否(fou)符合(he)的(de)(de)(de)(de)(de)(de)重要(yao)指標(biao)。當導體(ti)(ti)電(dian)(dian)阻超標(biao)時，就增大了(le)電(dian)(dian)流在線(xian)(xian)路上通過(guo)(guo)時的(de)(de)(de)(de)(de)(de)損耗，加(jia)劇(ju)了(le)電(dian)(dian)線(xian)(xian)電(dian)(dian)纜的(de)(de)(de)(de)(de)(de)發熱(re)。導體(ti)(ti)電(dian)(dian)阻不合(he)格的(de)(de)(de)(de)(de)(de)原因，主要(yao)進(jin)企業為了(le)降(jiang)低(di)成本(ben)，將占原材(cai)料(liao)成本(ben)80%的(de)(de)(de)(de)(de)(de)銅材(cai)縮水(shui)，要(yao)么(me)降(jiang)低(di)導體(ti)(ti)的(de)(de)(de)(de)(de)(de)截(jie)(jie)面積，要(yao)么(me)使用(yong)(yong)含雜(za)質過(guo)(guo)高的(de)(de)(de)(de)(de)(de)再生銅，這樣致使電(dian)(dian)線(xian)(xian)電(dian)(dian)纜的(de)(de)(de)(de)(de)(de)導體(ti)(ti)電(dian)(dian)阻嚴重超標(biao)，在使用(yong)(yong)過(guo)(guo)程中除易(yi)引發火災，還會加(jia)速包覆(fu)在電(dian)(dian)線(xian)(xian)外的(de)(de)(de)(de)(de)(de)絕緣(yuan)層(ceng)的(de)(de)(de)(de)(de)(de)老化。

在購買(mai)電(dian)(dian)線電(dian)(dian)纜的過程中(zhong)，消費者應注(zhu)意(yi)以下幾個(ge)事

第一、要觀察電線的(de)(de)外觀。合格產品的(de)(de)絕緣（護套）層(ceng)柔軟、有韌性和伸(shen)縮性、表面層(ceng)緊密、光滑、無粗糙(cao)感。如果(guo)包裹(guo)電線的(de)(de)塑料很容易被剝(bo)去(qu)，則存在塑料強度不(bu)夠的(de)(de)問題。

第二、要看電線的截面。合格產品的銅芯(xin)或(huo)鋁芯(xin)表(biao)面應該具有金(jin)屬光澤，表(biao)面發黑的銅或(huo)表(biao)面發白的鋁說(shuo)明(ming)已被氧化。

第三(san)、在購買(mai)電線時(shi)應注意(yi)查看質(zhi)量合(he)格(ge)證書。如(ru)果電線的質(zhi)量合(he)格(ge)，那么(me)其(qi)電線質(zhi)量應該也(ye)受過(guo)檢驗，不會有太大的問(wen)題。
