不合格電線電纜的危害

電(dian)線電(dian)纜是用于傳(chuan)輸電(dian)力(li)(li)、傳(chuan)輸信息和實現電(dian)磁能量轉換的(de)一大類電(dian)工產品(pin)。在抽查(cha)過程中，發現了大量的(de)不合(he)格(ge)產品(pin)，這些(xie)劣質產品(pin)給電(dian)力(li)(li)系統正常(chang)運行(xing)埋下諸(zhu)多隱(yin)患(huan)。

1、標(biao)(biao)志不合格(ge)的(de)(de)電(dian)線電(dian)纜。標(biao)(biao)志是(shi)電(dian)線電(dian)纜使用識(shi)別產品基本信息的(de)(de)主要途徑，根(gen)據標(biao)(biao)準規定(ding)標(biao)(biao)志的(de)(de)主要內(nei)容是(shi)：產品型號、規格(ge)、標(biao)(biao)準號、廠名、產地等在一(yi)定(ding)的(de)(de)標(biao)(biao)示間距內(nei)，當標(biao)(biao)志不合格(ge)時(shi)，會造成施(shi)工人員識(shi)別錯誤，嚴重時(shi)會引發電(dian)氣(qi)事故。

2、結構尺寸不合格(ge)的電(dian)(dian)線(xian)電(dian)(dian)纜。結構尺寸的主要(yao)問題是護(hu)(hu)套厚(hou)度(du)(du)，絕緣(yuan)厚(hou)度(du)(du)，當電(dian)(dian)纜的護(hu)(hu)套和(he)絕緣(yuan)厚(hou)度(du)(du)不達標(biao)時，致使電(dian)(dian)線(xian)電(dian)(dian)纜耐(nai)電(dian)(dian)氣強度(du)(du)會嚴重降低，導(dao)(dao)致電(dian)(dian)線(xian)電(dian)(dian)纜的使用壽命縮(suo)短，嚴重時可導(dao)(dao)致電(dian)(dian)線(xian)電(dian)(dian)纜被擊穿(chuan)，絕緣(yuan)（護(hu)(hu)套）層起不到(dao)正常(chang)保護(hu)(hu)作用，從而(er)發(fa)生電(dian)(dian)氣短路和(he)火災等現象。

3、護套式絕緣(yuan)老化前(qian)的(de)抗(kang)張(zhang)(zhang)強度、伸長(chang)率(lv)(lv)合格(ge)的(de)電(dian)(dian)線(xian)電(dian)(dian)纜(lan)。絕緣(yuan)護套老化前(qian)的(de)抗(kang)張(zhang)(zhang)強度、伸長(chang)率(lv)(lv)不合格(ge)直接大大縮(suo)短電(dian)(dian)線(xian)電(dian)(dian)纜(lan)的(de)工(gong)作用壽(shou)命(ming)，而且在(zai)施工(gong)或(huo)在(zai)長(chang)時間通電(dian)(dian)且溫度較高的(de)環境(jing)中，極(ji)易出現絕緣(yuan)體(ti)斷裂，致使帶電(dian)(dian)導體(ti)裸露，發生能觸(chu)電(dian)(dian)式短路危險。其不合格(ge)的(de)主要(yao)原因是使用了再生料(liao)生產，以降低產品(pin)成本，二是不具備生產資格(ge)小型企業(ye)。

4、導(dao)(dao)(dao)體(ti)電(dian)(dian)(dian)阻不合(he)格(ge)的(de)(de)電(dian)(dian)(dian)線(xian)(xian)(xian)(xian)。導(dao)(dao)(dao)體(ti)電(dian)(dian)(dian)阻主(zhu)要是考核(he)電(dian)(dian)(dian)線(xian)(xian)(xian)(xian)電(dian)(dian)(dian)纜的(de)(de)導(dao)(dao)(dao)體(ti)材料以及截面(mian)是否符合(he)的(de)(de)重要指標(biao)。當導(dao)(dao)(dao)體(ti)電(dian)(dian)(dian)阻超標(biao)時(shi)，就增大了(le)電(dian)(dian)(dian)流在(zai)線(xian)(xian)(xian)(xian)路上通(tong)過時(shi)的(de)(de)損耗(hao)，加(jia)劇(ju)了(le)電(dian)(dian)(dian)線(xian)(xian)(xian)(xian)電(dian)(dian)(dian)纜的(de)(de)發(fa)熱。導(dao)(dao)(dao)體(ti)電(dian)(dian)(dian)阻不合(he)格(ge)的(de)(de)原(yuan)因，主(zhu)要進企業為了(le)降(jiang)低(di)成(cheng)本，將占(zhan)原(yuan)材料成(cheng)本80%的(de)(de)銅材縮水，要么降(jiang)低(di)導(dao)(dao)(dao)體(ti)的(de)(de)截面(mian)積，要么使(shi)用含雜質過高的(de)(de)再生銅，這樣致(zhi)使(shi)電(dian)(dian)(dian)線(xian)(xian)(xian)(xian)電(dian)(dian)(dian)纜的(de)(de)導(dao)(dao)(dao)體(ti)電(dian)(dian)(dian)阻嚴(yan)重超標(biao)，在(zai)使(shi)用過程中除易(yi)引發(fa)火災，還會加(jia)速包覆在(zai)電(dian)(dian)(dian)線(xian)(xian)(xian)(xian)外的(de)(de)絕緣層(ceng)的(de)(de)老化。

在購買電線電纜(lan)的過程(cheng)中(zhong)，消費(fei)者(zhe)應注意以下幾個事

第一、要觀(guan)察電(dian)線(xian)(xian)的外觀(guan)。合(he)格(ge)產品(pin)的絕緣（護套）層(ceng)柔軟、有韌性(xing)和伸(shen)縮性(xing)、表面層(ceng)緊密、光滑、無(wu)粗糙感(gan)。如果(guo)包裹電(dian)線(xian)(xian)的塑料(liao)很(hen)容易被剝去，則存在塑料(liao)強度(du)不夠的問題。

第二、要(yao)看電線(xian)的(de)(de)(de)截面。合格產(chan)品的(de)(de)(de)銅芯(xin)(xin)或鋁芯(xin)(xin)表(biao)面應(ying)該(gai)具有(you)金屬光澤，表(biao)面發黑的(de)(de)(de)銅或表(biao)面發白的(de)(de)(de)鋁說明(ming)已被氧化。

第三、在購買電線時應注意查看(kan)質(zhi)量(liang)合(he)格(ge)證書。如果電線的質(zhi)量(liang)合(he)格(ge)，那(nei)么其電線質(zhi)量(liang)應該也受過檢驗，不會有太大(da)的問題。
