不合格電線電纜的危害

電(dian)(dian)(dian)線電(dian)(dian)(dian)纜是(shi)用于傳輸電(dian)(dian)(dian)力(li)(li)、傳輸信息和實(shi)現(xian)(xian)電(dian)(dian)(dian)磁能量轉換的一(yi)大類電(dian)(dian)(dian)工產(chan)品(pin)。在抽查(cha)過程中，發現(xian)(xian)了(le)大量的不合(he)格產(chan)品(pin)，這些劣質產(chan)品(pin)給電(dian)(dian)(dian)力(li)(li)系統正常運行埋下(xia)諸多隱患。

1、標(biao)志(zhi)(zhi)(zhi)不(bu)合格(ge)的(de)(de)電(dian)(dian)線電(dian)(dian)纜(lan)。標(biao)志(zhi)(zhi)(zhi)是電(dian)(dian)線電(dian)(dian)纜(lan)使用識別產品(pin)基本信(xin)息的(de)(de)主要途徑，根據標(biao)準規定(ding)標(biao)志(zhi)(zhi)(zhi)的(de)(de)主要內(nei)(nei)容是：產品(pin)型號、規格(ge)、標(biao)準號、廠名、產地(di)等(deng)在一定(ding)的(de)(de)標(biao)示間距內(nei)(nei)，當標(biao)志(zhi)(zhi)(zhi)不(bu)合格(ge)時，會(hui)造成施工人員識別錯誤，嚴重時會(hui)引發電(dian)(dian)氣事故(gu)。

2、結構尺寸不(bu)合(he)格的(de)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)。結構尺寸的(de)主(zhu)要問題是(shi)護套(tao)厚(hou)度，絕緣(yuan)厚(hou)度，當電(dian)(dian)(dian)纜(lan)的(de)護套(tao)和(he)絕緣(yuan)厚(hou)度不(bu)達標時(shi)(shi)，致(zhi)(zhi)(zhi)使電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)耐電(dian)(dian)(dian)氣(qi)強度會(hui)嚴重降低，導(dao)致(zhi)(zhi)(zhi)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)的(de)使用壽命縮短，嚴重時(shi)(shi)可導(dao)致(zhi)(zhi)(zhi)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)被擊穿(chuan)，絕緣(yuan)（護套(tao)）層起不(bu)到正常保(bao)護作用，從而(er)發(fa)生(sheng)電(dian)(dian)(dian)氣(qi)短路和(he)火災(zai)等現象。

3、護套式絕(jue)(jue)緣(yuan)老化前(qian)的抗(kang)張強度(du)、伸長率(lv)合(he)格(ge)(ge)的電(dian)(dian)線(xian)電(dian)(dian)纜。絕(jue)(jue)緣(yuan)護套老化前(qian)的抗(kang)張強度(du)、伸長率(lv)不合(he)格(ge)(ge)直接大大縮短(duan)電(dian)(dian)線(xian)電(dian)(dian)纜的工作用壽命，而且在施工或在長時(shi)間通電(dian)(dian)且溫度(du)較(jiao)高(gao)的環境(jing)中(zhong)，極易出現絕(jue)(jue)緣(yuan)體斷裂，致使帶電(dian)(dian)導體裸露，發生(sheng)能觸電(dian)(dian)式短(duan)路危險。其不合(he)格(ge)(ge)的主要原因(yin)是使用了再生(sheng)料生(sheng)產，以降低(di)產品(pin)成(cheng)本(ben)，二是不具備生(sheng)產資(zi)格(ge)(ge)小型企(qi)業。

4、導(dao)體(ti)電(dian)(dian)(dian)阻不(bu)合(he)(he)格(ge)的(de)(de)電(dian)(dian)(dian)線(xian)。導(dao)體(ti)電(dian)(dian)(dian)阻主(zhu)要是(shi)考核電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)的(de)(de)導(dao)體(ti)材料以及(ji)截(jie)面是(shi)否符(fu)合(he)(he)的(de)(de)重(zhong)要指標。當導(dao)體(ti)電(dian)(dian)(dian)阻超(chao)標時，就(jiu)增(zeng)大了電(dian)(dian)(dian)流在(zai)線(xian)路上(shang)通過(guo)時的(de)(de)損耗(hao)，加劇了電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)的(de)(de)發(fa)熱。導(dao)體(ti)電(dian)(dian)(dian)阻不(bu)合(he)(he)格(ge)的(de)(de)原因(yin)，主(zhu)要進企業為了降(jiang)低成本，將占(zhan)原材料成本80%的(de)(de)銅材縮水，要么降(jiang)低導(dao)體(ti)的(de)(de)截(jie)面積，要么使(shi)用(yong)含雜質過(guo)高的(de)(de)再(zai)生銅，這(zhe)樣致使(shi)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)的(de)(de)導(dao)體(ti)電(dian)(dian)(dian)阻嚴重(zhong)超(chao)標，在(zai)使(shi)用(yong)過(guo)程中除易引發(fa)火(huo)災，還會加速包覆在(zai)電(dian)(dian)(dian)線(xian)外的(de)(de)絕緣層的(de)(de)老(lao)化。

在(zai)購買電(dian)線電(dian)纜的過程中，消(xiao)費者應注意以下幾(ji)個事

第一(yi)、要(yao)觀(guan)察電(dian)線的(de)外觀(guan)。合格產品的(de)絕緣（護套）層柔軟(ruan)、有(you)韌性和伸縮(suo)性、表(biao)面層緊密、光滑(hua)、無粗糙感。如果(guo)包裹電(dian)線的(de)塑料(liao)很容(rong)易(yi)被剝(bo)去，則存(cun)在塑料(liao)強度不夠(gou)的(de)問題。

第(di)二、要看電線(xian)的(de)截面。合格產品的(de)銅芯(xin)或(huo)鋁芯(xin)表(biao)面應(ying)該具(ju)有金屬光澤，表(biao)面發(fa)黑的(de)銅或(huo)表(biao)面發(fa)白(bai)的(de)鋁說明已被氧化。

第(di)三、在(zai)購(gou)買電線時(shi)應(ying)注意(yi)查看質量(liang)(liang)合(he)格(ge)證書。如果電線的質量(liang)(liang)合(he)格(ge)，那么(me)其電線質量(liang)(liang)應(ying)該也受過檢驗(yan)，不會有太大的問題。
