不(bu)合格電(dian)線(xian)電(dian)纜的危(wei)害

電線電纜是用于(yu)傳輸電力(li)、傳輸信息(xi)和實(shi)現電磁能量轉換的一大類電工(gong)產(chan)(chan)品。在抽查過程中，發現了大量的不合格產(chan)(chan)品，這些(xie)劣(lie)質產(chan)(chan)品給(gei)電力(li)系統正常運行埋(mai)下(xia)諸多隱患。

1、標(biao)志不合格(ge)的(de)電(dian)線電(dian)纜(lan)。標(biao)志是電(dian)線電(dian)纜(lan)使用識別產(chan)品基本(ben)信(xin)息的(de)主要途徑，根據(ju)標(biao)準規(gui)定(ding)標(biao)志的(de)主要內容是：產(chan)品型號、規(gui)格(ge)、標(biao)準號、廠名、產(chan)地等在一(yi)定(ding)的(de)標(biao)示間距內，當標(biao)志不合格(ge)時，會造(zao)成施(shi)工人員識別錯誤，嚴(yan)重時會引發電(dian)氣(qi)事(shi)故。

2、結(jie)構尺寸(cun)不(bu)合格的電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)。結(jie)構尺寸(cun)的主要問題是(shi)護(hu)套厚(hou)度，絕緣厚(hou)度，當電(dian)(dian)(dian)纜(lan)的護(hu)套和絕緣厚(hou)度不(bu)達標時，致(zhi)使電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)耐(nai)電(dian)(dian)(dian)氣(qi)強度會嚴(yan)(yan)重降低，導(dao)(dao)致(zhi)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)的使用壽命縮短，嚴(yan)(yan)重時可導(dao)(dao)致(zhi)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)被擊穿(chuan)，絕緣（護(hu)套）層起不(bu)到正(zheng)常保(bao)護(hu)作(zuo)用，從而發生電(dian)(dian)(dian)氣(qi)短路(lu)和火災等現象。

3、護套(tao)式絕(jue)緣(yuan)老化前的(de)抗張強(qiang)度、伸長(chang)率合格的(de)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜。絕(jue)緣(yuan)護套(tao)老化前的(de)抗張強(qiang)度、伸長(chang)率不(bu)(bu)合格直接(jie)大大縮短(duan)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜的(de)工作用壽命，而且(qie)在(zai)施工或在(zai)長(chang)時間通電(dian)(dian)(dian)且(qie)溫(wen)度較高的(de)環境中，極(ji)易出現絕(jue)緣(yuan)體斷裂(lie)，致使(shi)帶電(dian)(dian)(dian)導體裸露，發生能觸(chu)電(dian)(dian)(dian)式短(duan)路危險。其不(bu)(bu)合格的(de)主(zhu)要原因是(shi)使(shi)用了再(zai)生料生產(chan)，以降(jiang)低產(chan)品成(cheng)本，二是(shi)不(bu)(bu)具備生產(chan)資格小型企業(ye)。

4、導(dao)(dao)(dao)體(ti)(ti)電(dian)(dian)阻(zu)(zu)不合(he)格的(de)(de)電(dian)(dian)線。導(dao)(dao)(dao)體(ti)(ti)電(dian)(dian)阻(zu)(zu)主(zhu)要是考核(he)電(dian)(dian)線電(dian)(dian)纜(lan)的(de)(de)導(dao)(dao)(dao)體(ti)(ti)材(cai)料(liao)以及截(jie)面是否符合(he)的(de)(de)重要指標。當(dang)導(dao)(dao)(dao)體(ti)(ti)電(dian)(dian)阻(zu)(zu)超標時，就增大了(le)電(dian)(dian)流在(zai)線路上(shang)通過(guo)時的(de)(de)損耗(hao)，加劇了(le)電(dian)(dian)線電(dian)(dian)纜(lan)的(de)(de)發熱。導(dao)(dao)(dao)體(ti)(ti)電(dian)(dian)阻(zu)(zu)不合(he)格的(de)(de)原(yuan)因，主(zhu)要進企業為了(le)降(jiang)低成本(ben)，將占原(yuan)材(cai)料(liao)成本(ben)80%的(de)(de)銅(tong)材(cai)縮(suo)水，要么降(jiang)低導(dao)(dao)(dao)體(ti)(ti)的(de)(de)截(jie)面積，要么使用含(han)雜質過(guo)高(gao)的(de)(de)再生銅(tong)，這樣致使電(dian)(dian)線電(dian)(dian)纜(lan)的(de)(de)導(dao)(dao)(dao)體(ti)(ti)電(dian)(dian)阻(zu)(zu)嚴重超標，在(zai)使用過(guo)程中除易引發火災，還會加速包(bao)覆在(zai)電(dian)(dian)線外的(de)(de)絕緣層(ceng)的(de)(de)老化(hua)。

在購(gou)買電(dian)線電(dian)纜的(de)過(guo)程(cheng)中，消費者應注意以下幾個(ge)事

第一、要觀察電線的外觀。合格產(chan)品的絕緣（護套）層柔軟(ruan)、有(you)韌性和伸縮性、表面層緊密(mi)、光滑、無粗糙感。如果(guo)包裹(guo)電線的塑料很容(rong)易被剝(bo)去，則存在塑料強(qiang)度不(bu)夠的問題。

第二(er)、要看電線的截(jie)面(mian)。合格產(chan)品(pin)的銅芯或鋁芯表(biao)(biao)面(mian)應該具有金屬光澤，表(biao)(biao)面(mian)發黑的銅或表(biao)(biao)面(mian)發白的鋁說明(ming)已被(bei)氧化。

第三、在購買(mai)電線時應注意查(cha)看質(zhi)量(liang)合格(ge)證書。如果電線的質(zhi)量(liang)合格(ge)，那么其電線質(zhi)量(liang)應該也受過檢驗，不會有太大(da)的問題。
