不合格電線電纜的危害(hai)

電(dian)線電(dian)纜(lan)是用于(yu)傳輸電(dian)力、傳輸信息(xi)和實現電(dian)磁能量(liang)轉換(huan)的(de)一大類電(dian)工產品。在抽(chou)查過程中，發現了大量(liang)的(de)不(bu)合(he)格(ge)產品，這些劣質產品給電(dian)力系(xi)統正常(chang)運行埋(mai)下諸多隱患。

1、標(biao)志不(bu)合格的(de)(de)電(dian)線電(dian)纜。標(biao)志是電(dian)線電(dian)纜使用識別產品基本(ben)信(xin)息的(de)(de)主要途(tu)徑(jing)，根(gen)據標(biao)準規定標(biao)志的(de)(de)主要內容是：產品型號、規格、標(biao)準號、廠名、產地等(deng)在一定的(de)(de)標(biao)示間距內，當標(biao)志不(bu)合格時，會造成施工人員識別錯誤，嚴重(zhong)時會引發電(dian)氣事故。

2、結(jie)構尺寸(cun)不(bu)合格(ge)的(de)電(dian)線電(dian)纜(lan)。結(jie)構尺寸(cun)的(de)主要問題是護(hu)套厚度，絕緣(yuan)厚度，當電(dian)纜(lan)的(de)護(hu)套和絕緣(yuan)厚度不(bu)達標時，致使電(dian)線電(dian)纜(lan)耐電(dian)氣強度會嚴重降低，導(dao)致電(dian)線電(dian)纜(lan)的(de)使用(yong)(yong)壽(shou)命縮(suo)短，嚴重時可導(dao)致電(dian)線電(dian)纜(lan)被擊(ji)穿，絕緣(yuan)（護(hu)套）層起不(bu)到(dao)正(zheng)常保(bao)護(hu)作用(yong)(yong)，從而發生電(dian)氣短路(lu)和火災(zai)等現(xian)象。

3、護套(tao)式絕緣(yuan)(yuan)老(lao)化前(qian)(qian)的(de)(de)抗張強(qiang)度、伸長(chang)率合(he)格(ge)(ge)的(de)(de)電(dian)(dian)線(xian)電(dian)(dian)纜。絕緣(yuan)(yuan)護套(tao)老(lao)化前(qian)(qian)的(de)(de)抗張強(qiang)度、伸長(chang)率不(bu)合(he)格(ge)(ge)直接大大縮短電(dian)(dian)線(xian)電(dian)(dian)纜的(de)(de)工(gong)作(zuo)用壽命，而且在(zai)施工(gong)或在(zai)長(chang)時(shi)間通電(dian)(dian)且溫度較高的(de)(de)環境中(zhong)，極易(yi)出現絕緣(yuan)(yuan)體(ti)(ti)斷(duan)裂，致使(shi)(shi)帶電(dian)(dian)導體(ti)(ti)裸露，發生(sheng)(sheng)(sheng)能觸電(dian)(dian)式短路危險。其不(bu)合(he)格(ge)(ge)的(de)(de)主要原因是使(shi)(shi)用了再生(sheng)(sheng)(sheng)料(liao)生(sheng)(sheng)(sheng)產(chan)，以降低產(chan)品成本，二是不(bu)具備(bei)生(sheng)(sheng)(sheng)產(chan)資格(ge)(ge)小型企業(ye)。

4、導(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)阻(zu)不合格的(de)(de)(de)(de)(de)電(dian)(dian)(dian)線(xian)(xian)。導(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)阻(zu)主要(yao)是(shi)考(kao)核(he)電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜的(de)(de)(de)(de)(de)導(dao)(dao)體(ti)(ti)材(cai)料以及(ji)截(jie)面是(shi)否符合的(de)(de)(de)(de)(de)重要(yao)指標(biao)。當導(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)阻(zu)超(chao)標(biao)時(shi)，就增(zeng)大了(le)電(dian)(dian)(dian)流(liu)在線(xian)(xian)路上通過(guo)(guo)(guo)時(shi)的(de)(de)(de)(de)(de)損耗，加劇了(le)電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜的(de)(de)(de)(de)(de)發熱。導(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)阻(zu)不合格的(de)(de)(de)(de)(de)原因(yin)，主要(yao)進企業為(wei)了(le)降(jiang)低成本，將占原材(cai)料成本80%的(de)(de)(de)(de)(de)銅(tong)材(cai)縮(suo)水，要(yao)么(me)降(jiang)低導(dao)(dao)體(ti)(ti)的(de)(de)(de)(de)(de)截(jie)面積，要(yao)么(me)使(shi)(shi)用(yong)含雜質過(guo)(guo)(guo)高的(de)(de)(de)(de)(de)再(zai)生銅(tong)，這樣致使(shi)(shi)電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜的(de)(de)(de)(de)(de)導(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)阻(zu)嚴重超(chao)標(biao)，在使(shi)(shi)用(yong)過(guo)(guo)(guo)程中(zhong)除(chu)易引(yin)發火災，還會加速(su)包覆在電(dian)(dian)(dian)線(xian)(xian)外的(de)(de)(de)(de)(de)絕緣層(ceng)的(de)(de)(de)(de)(de)老化。

在(zai)購買電(dian)(dian)線(xian)電(dian)(dian)纜的過程中，消費者(zhe)應注意以(yi)下幾個事

第一、要觀察電線的(de)外(wai)觀。合格產品的(de)絕緣(yuan)（護(hu)套）層(ceng)(ceng)柔軟(ruan)、有韌性和伸(shen)縮(suo)性、表面層(ceng)(ceng)緊密、光(guang)滑、無粗(cu)糙感。如果包(bao)裹電線的(de)塑料很容易被剝去，則存在塑料強度不夠(gou)的(de)問題。

第二、要看電(dian)線的(de)截(jie)面(mian)。合格產(chan)品的(de)銅(tong)芯或鋁芯表(biao)面(mian)應(ying)該具有(you)金屬光澤(ze)，表(biao)面(mian)發黑的(de)銅(tong)或表(biao)面(mian)發白的(de)鋁說明(ming)已被氧化(hua)。

第三、在(zai)購買電(dian)線時應注意(yi)查看質(zhi)(zhi)(zhi)量合(he)格(ge)證書(shu)。如果電(dian)線的(de)質(zhi)(zhi)(zhi)量合(he)格(ge)，那么其電(dian)線質(zhi)(zhi)(zhi)量應該也(ye)受過檢驗，不會有太大的(de)問(wen)題。
