不合(he)格電線電纜(lan)的危害

電(dian)線電(dian)纜是用于傳輸電(dian)力、傳輸信息和實現電(dian)磁(ci)能量轉換的(de)一大類電(dian)工產(chan)品。在(zai)抽查(cha)過程中，發現了(le)大量的(de)不合(he)格產(chan)品，這些劣質產(chan)品給(gei)電(dian)力系統正常(chang)運行埋下諸(zhu)多(duo)隱患(huan)。

1、標(biao)志(zhi)不合(he)格(ge)的電(dian)(dian)線電(dian)(dian)纜。標(biao)志(zhi)是(shi)電(dian)(dian)線電(dian)(dian)纜使用識別產(chan)品(pin)基本信息(xi)的主要(yao)途徑，根(gen)據標(biao)準規定標(biao)志(zhi)的主要(yao)內容(rong)是(shi)：產(chan)品(pin)型(xing)號、規格(ge)、標(biao)準號、廠名、產(chan)地等在一定的標(biao)示間距內，當標(biao)志(zhi)不合(he)格(ge)時，會(hui)造成(cheng)施工人(ren)員識別錯(cuo)誤(wu)，嚴重時會(hui)引發電(dian)(dian)氣事故。

2、結(jie)構(gou)尺寸不(bu)合格的(de)(de)電線(xian)(xian)(xian)電纜。結(jie)構(gou)尺寸的(de)(de)主要(yao)問題是護套厚(hou)度，絕(jue)(jue)緣厚(hou)度，當電纜的(de)(de)護套和(he)(he)絕(jue)(jue)緣厚(hou)度不(bu)達(da)標時(shi)，致(zhi)使電線(xian)(xian)(xian)電纜耐電氣(qi)強度會嚴(yan)重(zhong)降低，導致(zhi)電線(xian)(xian)(xian)電纜的(de)(de)使用(yong)壽命縮短(duan)，嚴(yan)重(zhong)時(shi)可導致(zhi)電線(xian)(xian)(xian)電纜被擊(ji)穿，絕(jue)(jue)緣（護套）層起不(bu)到(dao)正常保護作(zuo)用(yong)，從而發生電氣(qi)短(duan)路和(he)(he)火災等現象。

3、護套式絕(jue)緣(yuan)老化前的(de)(de)(de)抗(kang)張強度(du)、伸(shen)長率(lv)合(he)格(ge)的(de)(de)(de)電線電纜。絕(jue)緣(yuan)護套老化前的(de)(de)(de)抗(kang)張強度(du)、伸(shen)長率(lv)不合(he)格(ge)直(zhi)接(jie)大大縮(suo)短電線電纜的(de)(de)(de)工(gong)作用壽(shou)命(ming)，而且(qie)在施工(gong)或(huo)在長時間(jian)通電且(qie)溫度(du)較高(gao)的(de)(de)(de)環境中，極易出(chu)現絕(jue)緣(yuan)體斷裂(lie)，致使帶電導體裸露，發生能(neng)觸電式短路危(wei)險。其不合(he)格(ge)的(de)(de)(de)主要(yao)原因是(shi)使用了再生料生產，以降低產品成本，二(er)是(shi)不具(ju)備生產資格(ge)小型(xing)企業。

4、導(dao)體(ti)(ti)電(dian)(dian)(dian)阻(zu)(zu)不(bu)合(he)格(ge)的(de)(de)(de)電(dian)(dian)(dian)線(xian)。導(dao)體(ti)(ti)電(dian)(dian)(dian)阻(zu)(zu)主(zhu)要是(shi)考核電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)的(de)(de)(de)導(dao)體(ti)(ti)材料以及截面(mian)(mian)是(shi)否符合(he)的(de)(de)(de)重要指標(biao)。當導(dao)體(ti)(ti)電(dian)(dian)(dian)阻(zu)(zu)超標(biao)時，就增大了電(dian)(dian)(dian)流在(zai)線(xian)路上通過(guo)時的(de)(de)(de)損(sun)耗，加劇了電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)的(de)(de)(de)發熱。導(dao)體(ti)(ti)電(dian)(dian)(dian)阻(zu)(zu)不(bu)合(he)格(ge)的(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)銅(tong)材縮(suo)水，要么(me)(me)降低導(dao)體(ti)(ti)的(de)(de)(de)截面(mian)(mian)積，要么(me)(me)使用含雜質過(guo)高(gao)的(de)(de)(de)再生銅(tong)，這樣(yang)致(zhi)使電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)的(de)(de)(de)導(dao)體(ti)(ti)電(dian)(dian)(dian)阻(zu)(zu)嚴重超標(biao)，在(zai)使用過(guo)程(cheng)中除易引(yin)發火災(zai)，還會(hui)加速包覆(fu)在(zai)電(dian)(dian)(dian)線(xian)外的(de)(de)(de)絕緣層的(de)(de)(de)老化。

在購買電(dian)線電(dian)纜(lan)的過程(cheng)中，消費者應(ying)注意(yi)以下幾個(ge)事

第一、要(yao)觀(guan)察電(dian)線的(de)(de)外觀(guan)。合格產品的(de)(de)絕(jue)緣（護套）層柔軟、有韌性和(he)伸縮性、表面層緊密、光滑、無粗糙感。如果包裹電(dian)線的(de)(de)塑料很容易(yi)被剝去，則存在塑料強(qiang)度不(bu)夠的(de)(de)問(wen)題(ti)。

第二、要看電線的截(jie)面。合格產(chan)品的銅(tong)芯(xin)或鋁(lv)芯(xin)表(biao)面應該(gai)具有金屬光澤，表(biao)面發黑的銅(tong)或表(biao)面發白(bai)的鋁(lv)說明已(yi)被氧化。

第三、在購買電(dian)線時應注意查看質量合格證書。如果電(dian)線的質量合格，那(nei)么其電(dian)線質量應該也受過檢驗，不(bu)會有(you)太大的問題。
