不合格電線電纜(lan)的危(wei)害(hai)

電(dian)線電(dian)纜是用于傳輸電(dian)力(li)、傳輸信息和實現電(dian)磁能量轉換的(de)一大類電(dian)工產品。在抽查(cha)過(guo)程(cheng)中，發現了大量的(de)不(bu)合格(ge)產品，這些(xie)劣質(zhi)產品給電(dian)力(li)系統(tong)正(zheng)常運行埋(mai)下諸多隱患(huan)。

1、標(biao)(biao)志(zhi)不合格的(de)(de)電(dian)線電(dian)纜(lan)。標(biao)(biao)志(zhi)是電(dian)線電(dian)纜(lan)使用(yong)識(shi)別產(chan)品(pin)(pin)基本信息的(de)(de)主要途(tu)徑，根(gen)據標(biao)(biao)準(zhun)規定標(biao)(biao)志(zhi)的(de)(de)主要內容是：產(chan)品(pin)(pin)型號、規格、標(biao)(biao)準(zhun)號、廠名、產(chan)地等在一定的(de)(de)標(biao)(biao)示間距內，當(dang)標(biao)(biao)志(zhi)不合格時，會(hui)造成(cheng)施工人員識(shi)別錯(cuo)誤，嚴(yan)重時會(hui)引發電(dian)氣(qi)事(shi)故。

2、結構尺寸不(bu)合格的電(dian)(dian)線電(dian)(dian)纜(lan)(lan)(lan)。結構尺寸的主要問題是護套厚度(du)，絕緣(yuan)厚度(du)，當電(dian)(dian)纜(lan)(lan)(lan)的護套和(he)絕緣(yuan)厚度(du)不(bu)達標時(shi)，致(zhi)使電(dian)(dian)線電(dian)(dian)纜(lan)(lan)(lan)耐(nai)電(dian)(dian)氣強度(du)會嚴重(zhong)降低，導(dao)致(zhi)電(dian)(dian)線電(dian)(dian)纜(lan)(lan)(lan)的使用壽命縮(suo)短，嚴重(zhong)時(shi)可(ke)導(dao)致(zhi)電(dian)(dian)線電(dian)(dian)纜(lan)(lan)(lan)被擊穿(chuan)，絕緣(yuan)（護套）層起不(bu)到正常(chang)保護作用，從而發(fa)生(sheng)電(dian)(dian)氣短路(lu)和(he)火災等現象。

3、護套式絕緣老(lao)(lao)化前的抗張強度、伸長(chang)率(lv)合(he)格(ge)的電(dian)線(xian)電(dian)纜(lan)。絕緣護套老(lao)(lao)化前的抗張強度、伸長(chang)率(lv)不合(he)格(ge)直接大大縮(suo)短(duan)電(dian)線(xian)電(dian)纜(lan)的工作(zuo)用壽命，而(er)且在(zai)施(shi)工或在(zai)長(chang)時間通(tong)電(dian)且溫度較高(gao)的環(huan)境中，極易(yi)出現絕緣體斷裂，致(zhi)使帶電(dian)導(dao)體裸露(lu)，發生(sheng)能(neng)觸電(dian)式短(duan)路危險。其(qi)不合(he)格(ge)的主(zhu)要原(yuan)因(yin)是使用了再生(sheng)料(liao)生(sheng)產(chan)，以降低產(chan)品成本，二是不具備生(sheng)產(chan)資格(ge)小型企業。

4、導(dao)(dao)體(ti)(ti)(ti)電(dian)(dian)(dian)阻(zu)(zu)不(bu)合格的(de)電(dian)(dian)(dian)線(xian)。導(dao)(dao)體(ti)(ti)(ti)電(dian)(dian)(dian)阻(zu)(zu)主要是考核電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)的(de)導(dao)(dao)體(ti)(ti)(ti)材料(liao)以及截(jie)面是否(fou)符合的(de)重要指標(biao)。當(dang)導(dao)(dao)體(ti)(ti)(ti)電(dian)(dian)(dian)阻(zu)(zu)超標(biao)時，就(jiu)增大了(le)電(dian)(dian)(dian)流在線(xian)路上(shang)通過時的(de)損耗(hao)，加劇(ju)了(le)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)的(de)發(fa)熱。導(dao)(dao)體(ti)(ti)(ti)電(dian)(dian)(dian)阻(zu)(zu)不(bu)合格的(de)原因(yin)，主要進企業為了(le)降低(di)成(cheng)本，將占(zhan)原材料(liao)成(cheng)本80%的(de)銅材縮水(shui)，要么(me)降低(di)導(dao)(dao)體(ti)(ti)(ti)的(de)截(jie)面積(ji)，要么(me)使用(yong)含雜質(zhi)過高(gao)的(de)再生(sheng)銅，這樣致使電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)的(de)導(dao)(dao)體(ti)(ti)(ti)電(dian)(dian)(dian)阻(zu)(zu)嚴重超標(biao)，在使用(yong)過程(cheng)中除(chu)易引發(fa)火(huo)災，還(huan)會加速(su)包覆在電(dian)(dian)(dian)線(xian)外的(de)絕緣層的(de)老(lao)化。

在購買電(dian)線電(dian)纜(lan)的過程中，消費者(zhe)應(ying)注意以下(xia)幾(ji)個事(shi)

第一、要觀察電線的(de)(de)外觀。合格產品的(de)(de)絕緣(yuan)（護套）層(ceng)柔軟、有(you)韌性(xing)和伸(shen)縮性(xing)、表面層(ceng)緊密、光(guang)滑、無粗糙感(gan)。如果包裹電線的(de)(de)塑料很(hen)容易被剝(bo)去，則(ze)存在塑料強度不(bu)夠的(de)(de)問題。

第(di)二(er)、要看電線的(de)(de)截面。合格產品的(de)(de)銅芯(xin)(xin)或(huo)鋁(lv)芯(xin)(xin)表面應該具有金屬光澤，表面發黑的(de)(de)銅或(huo)表面發白的(de)(de)鋁(lv)說明已被氧化。

第三、在購買電線(xian)(xian)時應(ying)注(zhu)意(yi)查看質(zhi)(zhi)量合格證書。如果電線(xian)(xian)的質(zhi)(zhi)量合格，那么其電線(xian)(xian)質(zhi)(zhi)量應(ying)該也受(shou)過檢驗，不會有(you)太(tai)大的問題(ti)。
