不合(he)格電線電纜的危害

電(dian)線(xian)電(dian)纜是(shi)用于傳輸電(dian)力(li)、傳輸信(xin)息(xi)和實現電(dian)磁能量轉換的(de)一大類電(dian)工產(chan)品(pin)(pin)。在(zai)抽(chou)查過程中，發現了大量的(de)不合格產(chan)品(pin)(pin)，這些劣(lie)質產(chan)品(pin)(pin)給電(dian)力(li)系統正(zheng)常(chang)運行(xing)埋下諸多隱患。

1、標(biao)志(zhi)不合格(ge)的(de)(de)電(dian)線(xian)電(dian)纜(lan)。標(biao)志(zhi)是電(dian)線(xian)電(dian)纜(lan)使(shi)用識(shi)別產品(pin)基本信息的(de)(de)主(zhu)要途徑，根據(ju)標(biao)準規(gui)定(ding)標(biao)志(zhi)的(de)(de)主(zhu)要內容(rong)是：產品(pin)型號、規(gui)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，當(dang)標(biao)志(zhi)不合格(ge)時(shi)，會造成施工(gong)人員識(shi)別錯誤，嚴重時(shi)會引發電(dian)氣事故。

2、結(jie)(jie)構尺寸不合格的(de)電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜。結(jie)(jie)構尺寸的(de)主要問題是護(hu)套厚(hou)度，絕(jue)緣厚(hou)度，當(dang)電(dian)(dian)(dian)(dian)纜的(de)護(hu)套和絕(jue)緣厚(hou)度不達(da)標時，致使(shi)電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜耐電(dian)(dian)(dian)(dian)氣強度會嚴重降(jiang)低，導(dao)致電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜的(de)使(shi)用(yong)壽(shou)命(ming)縮短，嚴重時可導(dao)致電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜被(bei)擊穿(chuan)，絕(jue)緣（護(hu)套）層起不到(dao)正(zheng)常(chang)保護(hu)作用(yong)，從而發生(sheng)電(dian)(dian)(dian)(dian)氣短路和火(huo)災等現象。

3、護(hu)套(tao)式絕緣(yuan)老化前的(de)抗張(zhang)強度(du)(du)(du)、伸長率合(he)格(ge)(ge)的(de)電(dian)線(xian)電(dian)纜(lan)。絕緣(yuan)護(hu)套(tao)老化前的(de)抗張(zhang)強度(du)(du)(du)、伸長率不(bu)合(he)格(ge)(ge)直接大大縮短電(dian)線(xian)電(dian)纜(lan)的(de)工作用壽命，而且(qie)在施工或在長時間(jian)通電(dian)且(qie)溫度(du)(du)(du)較(jiao)高的(de)環(huan)境中，極易出現絕緣(yuan)體(ti)斷裂，致使帶電(dian)導體(ti)裸露，發生能觸(chu)電(dian)式短路危險。其不(bu)合(he)格(ge)(ge)的(de)主要原因(yin)是使用了(le)再生料生產，以降(jiang)低產品成本，二(er)是不(bu)具備生產資格(ge)(ge)小型企業(ye)。

4、導(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)(zu)不合(he)(he)格(ge)的(de)電(dian)(dian)(dian)(dian)線。導(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)(zu)主(zhu)要(yao)(yao)是考核電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)的(de)導(dao)體(ti)(ti)材(cai)料以及截面是否符合(he)(he)的(de)重要(yao)(yao)指標。當導(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)(zu)超標時，就(jiu)增大了電(dian)(dian)(dian)(dian)流在(zai)線路上通過時的(de)損耗，加劇(ju)了電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)的(de)發熱。導(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)(zu)不合(he)(he)格(ge)的(de)原因，主(zhu)要(yao)(yao)進企業為(wei)了降(jiang)(jiang)低(di)(di)成(cheng)(cheng)本，將占原材(cai)料成(cheng)(cheng)本80%的(de)銅材(cai)縮水，要(yao)(yao)么降(jiang)(jiang)低(di)(di)導(dao)體(ti)(ti)的(de)截面積，要(yao)(yao)么使用含(han)雜質(zhi)過高的(de)再(zai)生銅，這樣致使電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)的(de)導(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)(zu)嚴重超標，在(zai)使用過程中除易引發火(huo)災，還(huan)會加速包覆在(zai)電(dian)(dian)(dian)(dian)線外的(de)絕(jue)緣層的(de)老化。

在(zai)購買電線電纜(lan)的過程(cheng)中，消費(fei)者應(ying)注意以下幾個(ge)事

第一、要觀(guan)察電線(xian)的(de)外觀(guan)。合(he)格產品(pin)的(de)絕緣(yuan)（護(hu)套(tao)）層柔軟、有(you)韌性和伸(shen)縮(suo)性、表面層緊密、光(guang)滑、無粗糙感。如果包裹電線(xian)的(de)塑(su)料(liao)很容易被(bei)剝去(qu)，則存在塑(su)料(liao)強(qiang)度不夠的(de)問題。

第二、要看電(dian)線的截(jie)面(mian)。合格產品的銅芯或鋁(lv)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(lv)說明(ming)已被氧化。

第三、在購買電線時應(ying)注意(yi)查(cha)看(kan)質(zhi)量(liang)(liang)合格證書。如果電線的質(zhi)量(liang)(liang)合格，那(nei)么(me)其電線質(zhi)量(liang)(liang)應(ying)該也受過檢驗，不會有太大的問題。
