不合格電線(xian)電纜的危(wei)害(hai)

電(dian)線電(dian)纜是用于傳輸電(dian)力、傳輸信息(xi)和實現電(dian)磁能量轉換的(de)一大(da)類電(dian)工產(chan)品。在抽(chou)查過(guo)程中，發(fa)現了大(da)量的(de)不合(he)格產(chan)品，這些劣質產(chan)品給電(dian)力系(xi)統正常運行(xing)埋下(xia)諸多隱(yin)患。

1、標(biao)(biao)志(zhi)不(bu)合格的電線電纜(lan)(lan)。標(biao)(biao)志(zhi)是電線電纜(lan)(lan)使用識(shi)別產品(pin)基本信息的主要途(tu)徑，根(gen)據標(biao)(biao)準規(gui)定標(biao)(biao)志(zhi)的主要內(nei)容是：產品(pin)型號、規(gui)格、標(biao)(biao)準號、廠名(ming)、產地等(deng)在(zai)一定的標(biao)(biao)示間距內(nei)，當標(biao)(biao)志(zhi)不(bu)合格時，會造成施工(gong)人員識(shi)別錯誤，嚴重時會引發電氣事故。

2、結構(gou)尺寸(cun)不(bu)合格(ge)的電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)。結構(gou)尺寸(cun)的主要問題是護套(tao)厚(hou)度(du)，絕緣(yuan)厚(hou)度(du)，當電(dian)(dian)(dian)纜(lan)的護套(tao)和絕緣(yuan)厚(hou)度(du)不(bu)達標(biao)時(shi)，致(zhi)使電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)耐電(dian)(dian)(dian)氣強(qiang)度(du)會嚴重降低，導致(zhi)電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)的使用壽命縮短，嚴重時(shi)可導致(zhi)電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)被(bei)擊(ji)穿，絕緣(yuan)（護套(tao)）層起不(bu)到正(zheng)常保護作(zuo)用，從而發生電(dian)(dian)(dian)氣短路和火災等現象。

3、護套式絕(jue)(jue)緣(yuan)(yuan)老(lao)化(hua)前的(de)抗(kang)張強(qiang)度(du)、伸長(chang)率合格(ge)的(de)電(dian)(dian)線電(dian)(dian)纜。絕(jue)(jue)緣(yuan)(yuan)護套老(lao)化(hua)前的(de)抗(kang)張強(qiang)度(du)、伸長(chang)率不(bu)合格(ge)直接大(da)大(da)縮短電(dian)(dian)線電(dian)(dian)纜的(de)工作(zuo)用(yong)壽(shou)命，而(er)且在施(shi)工或在長(chang)時間通電(dian)(dian)且溫度(du)較高的(de)環境中，極(ji)易出現絕(jue)(jue)緣(yuan)(yuan)體斷裂，致使帶電(dian)(dian)導體裸露，發(fa)生能觸電(dian)(dian)式短路危(wei)險。其不(bu)合格(ge)的(de)主(zhu)要原因是使用(yong)了(le)再(zai)生料生產，以降低產品(pin)成本，二是不(bu)具備生產資格(ge)小(xiao)型企業(ye)。

4、導(dao)體(ti)電(dian)(dian)阻不合格(ge)的(de)(de)(de)電(dian)(dian)線。導(dao)體(ti)電(dian)(dian)阻主(zhu)要(yao)(yao)是考核電(dian)(dian)線電(dian)(dian)纜(lan)的(de)(de)(de)導(dao)體(ti)材料以及截面是否符(fu)合的(de)(de)(de)重要(yao)(yao)指標(biao)。當導(dao)體(ti)電(dian)(dian)阻超(chao)標(biao)時(shi)，就增(zeng)大(da)了(le)電(dian)(dian)流在(zai)線路上(shang)通過時(shi)的(de)(de)(de)損耗，加劇了(le)電(dian)(dian)線電(dian)(dian)纜(lan)的(de)(de)(de)發熱。導(dao)體(ti)電(dian)(dian)阻不合格(ge)的(de)(de)(de)原因(yin)，主(zhu)要(yao)(yao)進企業(ye)為了(le)降低成(cheng)本(ben)，將占原材料成(cheng)本(ben)80%的(de)(de)(de)銅材縮水(shui)，要(yao)(yao)么(me)降低導(dao)體(ti)的(de)(de)(de)截面積，要(yao)(yao)么(me)使(shi)(shi)用(yong)含雜質(zhi)過高的(de)(de)(de)再生銅，這樣致使(shi)(shi)電(dian)(dian)線電(dian)(dian)纜(lan)的(de)(de)(de)導(dao)體(ti)電(dian)(dian)阻嚴(yan)重超(chao)標(biao)，在(zai)使(shi)(shi)用(yong)過程中除易(yi)引發火災(zai)，還會加速包(bao)覆在(zai)電(dian)(dian)線外的(de)(de)(de)絕緣(yuan)層的(de)(de)(de)老化。

在購買電(dian)線電(dian)纜的過程中，消費者應注意以下幾(ji)個事

第一、要(yao)觀察電(dian)(dian)線(xian)的(de)(de)外觀。合格產品的(de)(de)絕緣（護套(tao)）層柔軟、有(you)韌(ren)性和伸縮性、表面層緊密、光滑、無粗糙感。如果包裹電(dian)(dian)線(xian)的(de)(de)塑(su)料很容易被剝去(qu)，則存在(zai)塑(su)料強度不夠的(de)(de)問題。

第二、要看電線的(de)截(jie)面。合(he)格產品的(de)銅芯(xin)(xin)或(huo)鋁芯(xin)(xin)表(biao)面應該具有(you)金屬光澤(ze)，表(biao)面發黑的(de)銅或(huo)表(biao)面發白的(de)鋁說明已被氧化。

第(di)三、在購買電線(xian)時應注意查看質量(liang)(liang)(liang)合格證(zheng)書。如果電線(xian)的質量(liang)(liang)(liang)合格，那么其電線(xian)質量(liang)(liang)(liang)應該也受過(guo)檢驗，不會有太(tai)大的問題。
