不合格電線(xian)電纜的危(wei)害

電(dian)(dian)線電(dian)(dian)纜是(shi)用于(yu)傳輸電(dian)(dian)力、傳輸信(xin)息(xi)和實現電(dian)(dian)磁能量(liang)轉換的(de)一大類電(dian)(dian)工產品。在(zai)抽查(cha)過程(cheng)中，發(fa)現了(le)大量(liang)的(de)不合格產品，這些劣質(zhi)產品給電(dian)(dian)力系統正常運行埋下諸多隱(yin)患。

1、標(biao)志不合(he)格(ge)的電(dian)線(xian)電(dian)纜。標(biao)志是(shi)(shi)電(dian)線(xian)電(dian)纜使用識別(bie)產(chan)品基本(ben)信(xin)息(xi)的主要(yao)途(tu)徑，根據標(biao)準(zhun)規定(ding)標(biao)志的主要(yao)內(nei)容(rong)是(shi)(shi)：產(chan)品型號、規格(ge)、標(biao)準(zhun)號、廠名、產(chan)地等在一定(ding)的標(biao)示間距內(nei)，當(dang)標(biao)志不合(he)格(ge)時，會(hui)造成施工人員識別(bie)錯誤，嚴(yan)重(zhong)時會(hui)引發電(dian)氣事故。

2、結(jie)構(gou)尺寸不合格的(de)(de)電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)。結(jie)構(gou)尺寸的(de)(de)主要問題(ti)是護(hu)套厚度，絕緣厚度，當電(dian)(dian)(dian)(dian)纜(lan)的(de)(de)護(hu)套和(he)(he)絕緣厚度不達標時，致使(shi)(shi)電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)耐電(dian)(dian)(dian)(dian)氣(qi)強度會嚴重降低(di)，導致電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)的(de)(de)使(shi)(shi)用壽(shou)命(ming)縮短(duan)，嚴重時可(ke)導致電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)被擊穿，絕緣（護(hu)套）層起不到正常保護(hu)作用，從而(er)發(fa)生電(dian)(dian)(dian)(dian)氣(qi)短(duan)路和(he)(he)火災等現象。

3、護(hu)(hu)套式絕(jue)緣(yuan)老(lao)化(hua)前的(de)抗張(zhang)強度、伸長(chang)率合格(ge)(ge)的(de)電(dian)(dian)線電(dian)(dian)纜。絕(jue)緣(yuan)護(hu)(hu)套老(lao)化(hua)前的(de)抗張(zhang)強度、伸長(chang)率不合格(ge)(ge)直(zhi)接(jie)大(da)大(da)縮短電(dian)(dian)線電(dian)(dian)纜的(de)工(gong)作用(yong)壽命(ming)，而且(qie)在施工(gong)或在長(chang)時間通電(dian)(dian)且(qie)溫度較(jiao)高(gao)的(de)環(huan)境中，極易出現絕(jue)緣(yuan)體斷裂，致使(shi)帶電(dian)(dian)導體裸露，發生能觸電(dian)(dian)式短路危(wei)險。其不合格(ge)(ge)的(de)主要(yao)原因是(shi)(shi)使(shi)用(yong)了再生料生產，以降低(di)產品成本，二是(shi)(shi)不具備生產資格(ge)(ge)小型企(qi)業。

4、導(dao)體(ti)(ti)(ti)電(dian)阻(zu)(zu)不合格的(de)電(dian)線(xian)(xian)。導(dao)體(ti)(ti)(ti)電(dian)阻(zu)(zu)主要(yao)是(shi)考核電(dian)線(xian)(xian)電(dian)纜的(de)導(dao)體(ti)(ti)(ti)材料以及(ji)截面(mian)是(shi)否(fou)符合的(de)重(zhong)要(yao)指標(biao)。當(dang)導(dao)體(ti)(ti)(ti)電(dian)阻(zu)(zu)超標(biao)時，就增大了(le)電(dian)流在(zai)線(xian)(xian)路上通過時的(de)損耗，加劇了(le)電(dian)線(xian)(xian)電(dian)纜的(de)發熱(re)。導(dao)體(ti)(ti)(ti)電(dian)阻(zu)(zu)不合格的(de)原因，主要(yao)進企業為了(le)降低成本，將占原材料成本80%的(de)銅材縮水，要(yao)么(me)(me)降低導(dao)體(ti)(ti)(ti)的(de)截面(mian)積，要(yao)么(me)(me)使用含雜質過高的(de)再生銅，這(zhe)樣致使電(dian)線(xian)(xian)電(dian)纜的(de)導(dao)體(ti)(ti)(ti)電(dian)阻(zu)(zu)嚴重(zhong)超標(biao)，在(zai)使用過程中除易(yi)引發火災(zai)，還會加速包覆在(zai)電(dian)線(xian)(xian)外(wai)的(de)絕(jue)緣層(ceng)的(de)老化。

在(zai)購買(mai)電線電纜的過程中，消費(fei)者(zhe)應注意以(yi)下幾個事

第(di)一、要觀察電線(xian)的外觀。合(he)格產品的絕(jue)緣（護套）層(ceng)柔軟、有韌(ren)性(xing)和伸縮(suo)性(xing)、表面層(ceng)緊密、光滑、無粗糙感。如果包裹電線(xian)的塑料(liao)很容(rong)易被(bei)剝去(qu)，則存在塑料(liao)強度不夠(gou)的問題。

第(di)二、要看電線(xian)的(de)(de)截面。合(he)格(ge)產品的(de)(de)銅(tong)芯或(huo)鋁芯表(biao)面應(ying)該具有金屬光澤(ze)，表(biao)面發黑(hei)的(de)(de)銅(tong)或(huo)表(biao)面發白的(de)(de)鋁說明已被(bei)氧(yang)化。

第三、在購買電(dian)(dian)線時應注意(yi)查看質(zhi)量合格證書(shu)。如果電(dian)(dian)線的質(zhi)量合格，那(nei)么其(qi)電(dian)(dian)線質(zhi)量應該也受(shou)過檢(jian)驗，不會(hui)有太大(da)的問題(ti)。
