不合(he)格(ge)電線電纜的危(wei)害

電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜是用于傳輸電(dian)(dian)(dian)力(li)(li)、傳輸信息和實現電(dian)(dian)(dian)磁(ci)能量轉換(huan)的一大(da)類(lei)電(dian)(dian)(dian)工產(chan)(chan)品。在抽查(cha)過(guo)程中(zhong)，發現了大(da)量的不合格產(chan)(chan)品，這(zhe)些劣質產(chan)(chan)品給電(dian)(dian)(dian)力(li)(li)系(xi)統(tong)正常(chang)運行埋下諸多隱患。

1、標(biao)(biao)志不(bu)合(he)格的電(dian)線電(dian)纜。標(biao)(biao)志是電(dian)線電(dian)纜使(shi)用識別產品(pin)基本信息的主要(yao)(yao)途徑，根(gen)據標(biao)(biao)準(zhun)規定標(biao)(biao)志的主要(yao)(yao)內容是：產品(pin)型號、規格、標(biao)(biao)準(zhun)號、廠名、產地等在(zai)一定的標(biao)(biao)示間(jian)距內，當標(biao)(biao)志不(bu)合(he)格時(shi)，會造成施工人員識別錯(cuo)誤，嚴重時(shi)會引發電(dian)氣事故(gu)。

2、結(jie)構(gou)尺寸(cun)不(bu)合格的(de)電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜。結(jie)構(gou)尺寸(cun)的(de)主要問題是護(hu)(hu)套厚(hou)度，絕緣(yuan)厚(hou)度，當電(dian)(dian)(dian)(dian)纜的(de)護(hu)(hu)套和絕緣(yuan)厚(hou)度不(bu)達標時，致使電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜耐(nai)電(dian)(dian)(dian)(dian)氣強度會嚴(yan)重降(jiang)低，導致電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜的(de)使用壽命(ming)縮短(duan)，嚴(yan)重時可(ke)導致電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜被擊穿(chuan)，絕緣(yuan)（護(hu)(hu)套）層起(qi)不(bu)到正(zheng)常(chang)保護(hu)(hu)作用，從(cong)而發生電(dian)(dian)(dian)(dian)氣短(duan)路和火(huo)災等現(xian)象。

3、護(hu)套式(shi)絕緣(yuan)(yuan)老(lao)化前的(de)(de)(de)抗(kang)張(zhang)強(qiang)度(du)、伸長率(lv)合格的(de)(de)(de)電線電纜。絕緣(yuan)(yuan)護(hu)套老(lao)化前的(de)(de)(de)抗(kang)張(zhang)強(qiang)度(du)、伸長率(lv)不合格直接大大縮短(duan)電線電纜的(de)(de)(de)工作用(yong)壽命，而且在施工或(huo)在長時間通(tong)電且溫度(du)較高的(de)(de)(de)環境中，極(ji)易出現絕緣(yuan)(yuan)體斷(duan)裂，致使帶電導體裸露，發生能觸電式(shi)短(duan)路危險(xian)。其不合格的(de)(de)(de)主要(yao)原因是使用(yong)了再(zai)生料生產，以降低產品成本，二是不具備生產資格小型企業。

4、導(dao)(dao)(dao)體(ti)電(dian)(dian)阻(zu)(zu)不合格(ge)的(de)(de)(de)(de)(de)電(dian)(dian)線(xian)。導(dao)(dao)(dao)體(ti)電(dian)(dian)阻(zu)(zu)主要(yao)(yao)是(shi)(shi)考核電(dian)(dian)線(xian)電(dian)(dian)纜的(de)(de)(de)(de)(de)導(dao)(dao)(dao)體(ti)材(cai)料(liao)以及截面是(shi)(shi)否符(fu)合的(de)(de)(de)(de)(de)重要(yao)(yao)指標。當(dang)導(dao)(dao)(dao)體(ti)電(dian)(dian)阻(zu)(zu)超標時，就增(zeng)大了電(dian)(dian)流(liu)在(zai)線(xian)路上通過(guo)時的(de)(de)(de)(de)(de)損耗，加(jia)(jia)劇了電(dian)(dian)線(xian)電(dian)(dian)纜的(de)(de)(de)(de)(de)發熱。導(dao)(dao)(dao)體(ti)電(dian)(dian)阻(zu)(zu)不合格(ge)的(de)(de)(de)(de)(de)原因，主要(yao)(yao)進企業為了降(jiang)低(di)成(cheng)本，將占原材(cai)料(liao)成(cheng)本80%的(de)(de)(de)(de)(de)銅材(cai)縮(suo)水，要(yao)(yao)么降(jiang)低(di)導(dao)(dao)(dao)體(ti)的(de)(de)(de)(de)(de)截面積，要(yao)(yao)么使用含雜質(zhi)過(guo)高的(de)(de)(de)(de)(de)再(zai)生銅，這樣致(zhi)使電(dian)(dian)線(xian)電(dian)(dian)纜的(de)(de)(de)(de)(de)導(dao)(dao)(dao)體(ti)電(dian)(dian)阻(zu)(zu)嚴重超標，在(zai)使用過(guo)程中(zhong)除易引發火(huo)災，還(huan)會加(jia)(jia)速包覆在(zai)電(dian)(dian)線(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(de)過程中，消(xiao)費者(zhe)應注意以下幾個事

第(di)一、要觀察(cha)電線(xian)的外(wai)觀。合格產(chan)品的絕緣（護套(tao)）層柔(rou)軟、有韌(ren)性和伸(shen)縮性、表(biao)面層緊密、光滑、無(wu)粗糙感。如果包裹(guo)電線(xian)的塑(su)料(liao)很(hen)容易被剝去，則存(cun)在塑(su)料(liao)強度不夠的問題。

第二(er)、要看電(dian)線的(de)截(jie)面(mian)。合格產品的(de)銅(tong)芯(xin)或鋁芯(xin)表(biao)面(mian)應該具有(you)金屬光澤，表(biao)面(mian)發(fa)黑(hei)的(de)銅(tong)或表(biao)面(mian)發(fa)白的(de)鋁說(shuo)明已被氧化。

第三、在(zai)購買電線時應注(zhu)意查看質(zhi)量合(he)(he)格證書。如果電線的質(zhi)量合(he)(he)格，那么(me)其電線質(zhi)量應該也(ye)受過(guo)檢驗(yan)，不(bu)會有太大的問(wen)題。
