不合(he)格電(dian)線電(dian)纜的(de)危害(hai)

電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜是用于傳輸電(dian)(dian)(dian)(dian)力(li)、傳輸信息和實現電(dian)(dian)(dian)(dian)磁能(neng)量(liang)(liang)轉換的一大類電(dian)(dian)(dian)(dian)工(gong)產(chan)品(pin)。在抽(chou)查過程中，發現了大量(liang)(liang)的不合格(ge)產(chan)品(pin)，這些(xie)劣質產(chan)品(pin)給電(dian)(dian)(dian)(dian)力(li)系統(tong)正常運(yun)行埋(mai)下諸多隱(yin)患。

1、標(biao)志(zhi)(zhi)不合格(ge)的電線電纜(lan)。標(biao)志(zhi)(zhi)是電線電纜(lan)使用識別產(chan)品(pin)基本信息的主要途徑，根據標(biao)準(zhun)規定(ding)(ding)標(biao)志(zhi)(zhi)的主要內(nei)容是：產(chan)品(pin)型(xing)號、規格(ge)、標(biao)準(zhun)號、廠名、產(chan)地(di)等在(zai)一定(ding)(ding)的標(biao)示(shi)間距內(nei)，當標(biao)志(zhi)(zhi)不合格(ge)時，會造(zao)成施工人員識別錯誤，嚴重時會引發電氣事故。

2、結構尺寸(cun)不(bu)合(he)格的電線(xian)電纜。結構尺寸(cun)的主要(yao)問題是護(hu)套(tao)厚度(du)，絕(jue)緣(yuan)(yuan)厚度(du)，當電纜的護(hu)套(tao)和絕(jue)緣(yuan)(yuan)厚度(du)不(bu)達標時(shi)，致(zhi)使(shi)電線(xian)電纜耐電氣(qi)強度(du)會嚴(yan)重降低，導致(zhi)電線(xian)電纜的使(shi)用壽命縮短，嚴(yan)重時(shi)可導致(zhi)電線(xian)電纜被擊穿(chuan)，絕(jue)緣(yuan)(yuan)（護(hu)套(tao)）層起不(bu)到正(zheng)常(chang)保護(hu)作用，從(cong)而發生(sheng)電氣(qi)短路和火災等現象。

3、護(hu)套(tao)式絕(jue)緣(yuan)老(lao)化前(qian)的抗張(zhang)強度(du)(du)、伸長(chang)率合(he)(he)格的電(dian)線電(dian)纜。絕(jue)緣(yuan)護(hu)套(tao)老(lao)化前(qian)的抗張(zhang)強度(du)(du)、伸長(chang)率不(bu)(bu)(bu)合(he)(he)格直接大(da)大(da)縮短(duan)電(dian)線電(dian)纜的工(gong)作(zuo)用壽(shou)命，而且在施工(gong)或在長(chang)時間通電(dian)且溫(wen)度(du)(du)較高(gao)的環境(jing)中，極(ji)易出(chu)現絕(jue)緣(yuan)體斷(duan)裂(lie)，致使(shi)帶電(dian)導體裸露(lu)，發生能觸電(dian)式短(duan)路危險。其不(bu)(bu)(bu)合(he)(he)格的主(zhu)要原因(yin)是(shi)(shi)使(shi)用了(le)再(zai)生料生產，以降低產品成本，二(er)是(shi)(shi)不(bu)(bu)(bu)具備生產資格小型企業(ye)。

4、導(dao)(dao)(dao)體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻不(bu)合格的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)線。導(dao)(dao)(dao)體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻主要(yao)是(shi)考核電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜的(de)(de)導(dao)(dao)(dao)體(ti)材料(liao)以及(ji)截面(mian)是(shi)否符(fu)合的(de)(de)重(zhong)要(yao)指標。當導(dao)(dao)(dao)體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻超標時(shi)，就增大了電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流在(zai)線路上通(tong)過時(shi)的(de)(de)損耗，加劇了電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜的(de)(de)發熱。導(dao)(dao)(dao)體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻不(bu)合格的(de)(de)原因，主要(yao)進企業為了降低成本(ben)，將占原材料(liao)成本(ben)80%的(de)(de)銅材縮水，要(yao)么降低導(dao)(dao)(dao)體(ti)的(de)(de)截面(mian)積(ji)，要(yao)么使(shi)用(yong)含(han)雜質過高的(de)(de)再(zai)生銅，這樣致(zhi)使(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜的(de)(de)導(dao)(dao)(dao)體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻嚴重(zhong)超標，在(zai)使(shi)用(yong)過程中除易引(yin)發火災，還會加速(su)包覆在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)線外的(de)(de)絕緣層的(de)(de)老化。

在購買(mai)電線(xian)電纜的(de)過程中(zhong)，消費者應(ying)注(zhu)意以下幾(ji)個事

第一、要(yao)觀察電(dian)線(xian)的外觀。合格(ge)產品(pin)的絕緣（護(hu)套）層柔軟、有韌(ren)性和伸縮性、表面層緊密、光滑、無粗糙(cao)感。如(ru)果包裹電(dian)線(xian)的塑(su)料很容易被剝去(qu)，則存在(zai)塑(su)料強(qiang)度(du)不夠的問題。

第二(er)、要看(kan)電線的(de)截面。合格產品的(de)銅芯或鋁芯表(biao)(biao)面應該具有金屬光(guang)澤(ze)，表(biao)(biao)面發黑(hei)的(de)銅或表(biao)(biao)面發白的(de)鋁說明已被(bei)氧化。

第(di)三、在購買電線時應(ying)注意查看質量(liang)合格證書(shu)。如果電線的質量(liang)合格，那(nei)么其電線質量(liang)應(ying)該也受(shou)過檢驗(yan)，不(bu)會有(you)太大的問題。
