不合(he)格電線電纜的危害

電線電纜是用于傳輸(shu)電力、傳輸(shu)信息和(he)實(shi)現(xian)電磁能量(liang)轉換的一大類電工產品。在抽(chou)查過程(cheng)中，發(fa)現(xian)了大量(liang)的不合格產品，這些劣(lie)質產品給電力系統正(zheng)常運行(xing)埋下(xia)諸多隱(yin)患。

1、標(biao)志不合格(ge)的(de)電(dian)線電(dian)纜。標(biao)志是電(dian)線電(dian)纜使(shi)用(yong)識(shi)別(bie)產(chan)(chan)品(pin)基本(ben)信息的(de)主要(yao)途(tu)徑，根據標(biao)準規(gui)定標(biao)志的(de)主要(yao)內容(rong)是：產(chan)(chan)品(pin)型號、規(gui)格(ge)、標(biao)準號、廠名、產(chan)(chan)地等在一(yi)定的(de)標(biao)示間距(ju)內，當(dang)標(biao)志不合格(ge)時，會造成施工人員識(shi)別(bie)錯誤，嚴重(zhong)時會引發電(dian)氣事故。

2、結構尺(chi)寸(cun)不(bu)(bu)合格(ge)的(de)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)。結構尺(chi)寸(cun)的(de)主要問題是護套厚(hou)度，絕緣(yuan)(yuan)厚(hou)度，當電(dian)(dian)(dian)纜(lan)的(de)護套和絕緣(yuan)(yuan)厚(hou)度不(bu)(bu)達(da)標時(shi)，致(zhi)(zhi)使電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)耐電(dian)(dian)(dian)氣強度會(hui)嚴(yan)重降(jiang)低，導致(zhi)(zhi)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)的(de)使用(yong)(yong)壽命縮短，嚴(yan)重時(shi)可(ke)導致(zhi)(zhi)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)被擊穿，絕緣(yuan)(yuan)（護套）層起不(bu)(bu)到正(zheng)常保護作用(yong)(yong)，從而發(fa)生電(dian)(dian)(dian)氣短路和火災等(deng)現象(xiang)。

3、護(hu)套(tao)式絕緣老化(hua)前的抗(kang)張(zhang)(zhang)強(qiang)(qiang)度(du)、伸長(chang)率(lv)合(he)(he)格(ge)的電(dian)(dian)線(xian)電(dian)(dian)纜。絕緣護(hu)套(tao)老化(hua)前的抗(kang)張(zhang)(zhang)強(qiang)(qiang)度(du)、伸長(chang)率(lv)不(bu)(bu)合(he)(he)格(ge)直接(jie)大(da)大(da)縮短電(dian)(dian)線(xian)電(dian)(dian)纜的工作用(yong)壽命，而且在(zai)施工或在(zai)長(chang)時間(jian)通電(dian)(dian)且溫度(du)較高(gao)的環境中，極易出現絕緣體斷裂，致(zhi)使帶電(dian)(dian)導體裸露，發生(sheng)能觸電(dian)(dian)式短路(lu)危(wei)險(xian)。其不(bu)(bu)合(he)(he)格(ge)的主(zhu)要原(yuan)因是使用(yong)了再(zai)生(sheng)料生(sheng)產，以降低產品(pin)成本(ben)，二(er)是不(bu)(bu)具(ju)備(bei)生(sheng)產資(zi)格(ge)小型企業。

4、導體(ti)(ti)(ti)(ti)電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)不合格的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)。導體(ti)(ti)(ti)(ti)電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)主要(yao)(yao)(yao)是考核電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)(dian)(dian)纜(lan)的(de)(de)(de)(de)導體(ti)(ti)(ti)(ti)材(cai)料以及截面(mian)是否符合的(de)(de)(de)(de)重要(yao)(yao)(yao)指標。當導體(ti)(ti)(ti)(ti)電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)超標時，就增大(da)了電(dian)(dian)(dian)(dian)(dian)流在線(xian)(xian)(xian)路上通過時的(de)(de)(de)(de)損耗，加(jia)劇(ju)了電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)(dian)(dian)纜(lan)的(de)(de)(de)(de)發熱。導體(ti)(ti)(ti)(ti)電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)不合格的(de)(de)(de)(de)原(yuan)因，主要(yao)(yao)(yao)進企業為了降(jiang)低(di)成(cheng)本，將占原(yuan)材(cai)料成(cheng)本80%的(de)(de)(de)(de)銅材(cai)縮(suo)水，要(yao)(yao)(yao)么降(jiang)低(di)導體(ti)(ti)(ti)(ti)的(de)(de)(de)(de)截面(mian)積，要(yao)(yao)(yao)么使用含雜質過高(gao)的(de)(de)(de)(de)再生銅，這樣致使電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)(dian)(dian)纜(lan)的(de)(de)(de)(de)導體(ti)(ti)(ti)(ti)電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)嚴重超標，在使用過程(cheng)中除易引發火災(zai)，還會加(jia)速(su)包(bao)覆(fu)在電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)外的(de)(de)(de)(de)絕緣層的(de)(de)(de)(de)老化。

在購買電線電纜的過程中，消費者應注意以(yi)下幾個事(shi)

第(di)一、要觀(guan)察電線的外觀(guan)。合(he)格產品的絕緣（護(hu)套）層柔軟、有韌(ren)性(xing)和伸縮(suo)性(xing)、表面(mian)層緊密、光滑、無粗糙感。如(ru)果(guo)包裹(guo)電線的塑料很容易被剝去(qu)，則存(cun)在塑料強度不夠(gou)的問題。

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

第三、在購買電(dian)(dian)線(xian)時應注(zhu)意查看質量(liang)(liang)合格證(zheng)書。如果(guo)電(dian)(dian)線(xian)的(de)質量(liang)(liang)合格，那么其電(dian)(dian)線(xian)質量(liang)(liang)應該也受過檢驗，不會有太大的(de)問題。
