不合(he)格(ge)電(dian)線電(dian)纜的危害

電(dian)(dian)線電(dian)(dian)纜(lan)是用于(yu)傳輸電(dian)(dian)力、傳輸信(xin)息和實現電(dian)(dian)磁能量轉換的一大類電(dian)(dian)工產(chan)品(pin)。在抽查過程(cheng)中，發現了(le)大量的不合格產(chan)品(pin)，這(zhe)些劣質產(chan)品(pin)給電(dian)(dian)力系(xi)統(tong)正常運行埋下諸多(duo)隱患。

1、標(biao)(biao)(biao)志(zhi)不(bu)合格(ge)的(de)電線(xian)電纜。標(biao)(biao)(biao)志(zhi)是電線(xian)電纜使(shi)用識別產(chan)品基本信(xin)息的(de)主(zhu)要(yao)途徑，根據標(biao)(biao)(biao)準規定(ding)標(biao)(biao)(biao)志(zhi)的(de)主(zhu)要(yao)內(nei)容是：產(chan)品型號、規格(ge)、標(biao)(biao)(biao)準號、廠名、產(chan)地等在一(yi)定(ding)的(de)標(biao)(biao)(biao)示間距內(nei)，當(dang)標(biao)(biao)(biao)志(zhi)不(bu)合格(ge)時，會(hui)造成施工(gong)人員識別錯(cuo)誤，嚴(yan)重時會(hui)引發電氣(qi)事故(gu)。

2、結構尺寸(cun)不合格(ge)的(de)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)。結構尺寸(cun)的(de)主要(yao)問題是護套(tao)(tao)(tao)厚度(du)，絕緣(yuan)厚度(du)，當電(dian)(dian)(dian)纜(lan)的(de)護套(tao)(tao)(tao)和絕緣(yuan)厚度(du)不達標時(shi)，致(zhi)使(shi)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)耐電(dian)(dian)(dian)氣(qi)強度(du)會嚴重降低，導(dao)致(zhi)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)的(de)使(shi)用壽命縮(suo)短，嚴重時(shi)可(ke)導(dao)致(zhi)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)被擊穿，絕緣(yuan)（護套(tao)(tao)(tao)）層起(qi)不到正(zheng)常保(bao)護作用，從而(er)發生電(dian)(dian)(dian)氣(qi)短路和火(huo)災(zai)等現(xian)象。

3、護套(tao)式(shi)絕緣老(lao)化(hua)前的(de)(de)抗張(zhang)強(qiang)度(du)、伸(shen)(shen)長(chang)率合(he)格(ge)的(de)(de)電(dian)線電(dian)纜。絕緣護套(tao)老(lao)化(hua)前的(de)(de)抗張(zhang)強(qiang)度(du)、伸(shen)(shen)長(chang)率不合(he)格(ge)直接大大縮(suo)短電(dian)線電(dian)纜的(de)(de)工(gong)作用壽命，而且在施工(gong)或在長(chang)時間通電(dian)且溫度(du)較高的(de)(de)環境(jing)中(zhong)，極(ji)易出(chu)現絕緣體斷裂，致使帶(dai)電(dian)導體裸露，發生(sheng)(sheng)(sheng)能(neng)觸電(dian)式(shi)短路危險。其不合(he)格(ge)的(de)(de)主要原因是使用了再生(sheng)(sheng)(sheng)料(liao)生(sheng)(sheng)(sheng)產，以降低產品成本，二(er)是不具備生(sheng)(sheng)(sheng)產資格(ge)小型企業。

4、導(dao)體電阻(zu)不(bu)(bu)合(he)格的(de)(de)(de)(de)(de)電線(xian)(xian)。導(dao)體電阻(zu)主要(yao)(yao)是考核(he)電線(xian)(xian)電纜的(de)(de)(de)(de)(de)導(dao)體材料(liao)以及截面是否符合(he)的(de)(de)(de)(de)(de)重要(yao)(yao)指標(biao)。當(dang)導(dao)體電阻(zu)超標(biao)時，就(jiu)增大了(le)電流(liu)在線(xian)(xian)路上通過時的(de)(de)(de)(de)(de)損(sun)耗，加劇了(le)電線(xian)(xian)電纜的(de)(de)(de)(de)(de)發(fa)熱。導(dao)體電阻(zu)不(bu)(bu)合(he)格的(de)(de)(de)(de)(de)原因，主要(yao)(yao)進企業為了(le)降(jiang)(jiang)低(di)成(cheng)本(ben)，將占(zhan)原材料(liao)成(cheng)本(ben)80%的(de)(de)(de)(de)(de)銅材縮(suo)水，要(yao)(yao)么降(jiang)(jiang)低(di)導(dao)體的(de)(de)(de)(de)(de)截面積，要(yao)(yao)么使用含雜質過高的(de)(de)(de)(de)(de)再生銅，這樣致使電線(xian)(xian)電纜的(de)(de)(de)(de)(de)導(dao)體電阻(zu)嚴重超標(biao)，在使用過程中除易引發(fa)火災，還會加速包(bao)覆在電線(xian)(xian)外的(de)(de)(de)(de)(de)絕緣層的(de)(de)(de)(de)(de)老化。

在(zai)購買電線電纜的過程(cheng)中，消費者應注意以下幾個事

第一、要觀察電線的(de)外(wai)觀。合格產(chan)品的(de)絕緣（護(hu)套）層(ceng)柔軟、有(you)韌性和伸縮性、表面層(ceng)緊密、光滑、無(wu)粗糙(cao)感。如果(guo)包(bao)裹電線的(de)塑(su)料(liao)(liao)很容易(yi)被剝去，則(ze)存(cun)在塑(su)料(liao)(liao)強(qiang)度不夠的(de)問題。

第二、要(yao)看電線的(de)截面(mian)。合格產品(pin)的(de)銅芯或鋁芯表面(mian)應該(gai)具(ju)有金屬光澤，表面(mian)發(fa)黑(hei)的(de)銅或表面(mian)發(fa)白的(de)鋁說(shuo)明已被氧化。

第(di)三、在(zai)購買電(dian)線(xian)時(shi)應(ying)注意查看質(zhi)量(liang)合格證書。如果電(dian)線(xian)的質(zhi)量(liang)合格，那么其電(dian)線(xian)質(zhi)量(liang)應(ying)該也(ye)受(shou)過(guo)檢驗，不會有太大的問題。
