不合(he)格電線電纜的危(wei)害

電(dian)(dian)線電(dian)(dian)纜是用(yong)于傳輸電(dian)(dian)力(li)(li)、傳輸信息和實(shi)現電(dian)(dian)磁能(neng)量(liang)轉換的一大類電(dian)(dian)工產品(pin)(pin)。在抽查過程中，發現了大量(liang)的不合格產品(pin)(pin)，這些劣質產品(pin)(pin)給電(dian)(dian)力(li)(li)系(xi)統正常運行埋下(xia)諸多隱患。

1、標志不合格的(de)電(dian)線(xian)電(dian)纜(lan)。標志是電(dian)線(xian)電(dian)纜(lan)使用識別(bie)產(chan)品(pin)基(ji)本信息的(de)主要途(tu)徑，根據(ju)標準規定標志的(de)主要內容是：產(chan)品(pin)型號、規格、標準號、廠名、產(chan)地等在一定的(de)標示間距內，當(dang)標志不合格時，會造成施工人員(yuan)識別(bie)錯誤，嚴重時會引(yin)發電(dian)氣(qi)事故。

2、結構(gou)尺寸不合格的(de)(de)電(dian)線電(dian)纜。結構(gou)尺寸的(de)(de)主要問(wen)題(ti)是護(hu)套(tao)(tao)(tao)厚(hou)(hou)度(du)，絕緣厚(hou)(hou)度(du)，當電(dian)纜的(de)(de)護(hu)套(tao)(tao)(tao)和(he)(he)絕緣厚(hou)(hou)度(du)不達標(biao)時，致(zhi)使電(dian)線電(dian)纜耐(nai)電(dian)氣(qi)強度(du)會(hui)嚴(yan)重(zhong)降低，導致(zhi)電(dian)線電(dian)纜的(de)(de)使用(yong)壽(shou)命縮(suo)短(duan)，嚴(yan)重(zhong)時可導致(zhi)電(dian)線電(dian)纜被(bei)擊穿，絕緣（護(hu)套(tao)(tao)(tao)）層起不到正常(chang)保護(hu)作(zuo)用(yong)，從而發生電(dian)氣(qi)短(duan)路和(he)(he)火災等(deng)現象。

3、護套(tao)式絕(jue)緣(yuan)老化前的(de)(de)(de)(de)抗(kang)張(zhang)強(qiang)度、伸長率(lv)合格(ge)的(de)(de)(de)(de)電線電纜。絕(jue)緣(yuan)護套(tao)老化前的(de)(de)(de)(de)抗(kang)張(zhang)強(qiang)度、伸長率(lv)不(bu)(bu)合格(ge)直(zhi)接大大縮短電線電纜的(de)(de)(de)(de)工作用壽命，而且(qie)在(zai)施(shi)工或在(zai)長時間通(tong)電且(qie)溫度較(jiao)高(gao)的(de)(de)(de)(de)環境中，極易(yi)出現絕(jue)緣(yuan)體斷裂，致使帶電導(dao)體裸露，發生能觸電式短路(lu)危險。其不(bu)(bu)合格(ge)的(de)(de)(de)(de)主要原因是使用了再生料生產，以(yi)降低產品成本，二是不(bu)(bu)具備生產資格(ge)小型企(qi)業。

4、導(dao)體(ti)(ti)電(dian)(dian)(dian)阻不合(he)格(ge)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)線(xian)(xian)。導(dao)體(ti)(ti)電(dian)(dian)(dian)阻主(zhu)要(yao)是考核(he)電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)的(de)(de)(de)(de)(de)導(dao)體(ti)(ti)材料以及截(jie)面(mian)是否符合(he)的(de)(de)(de)(de)(de)重要(yao)指標。當導(dao)體(ti)(ti)電(dian)(dian)(dian)阻超標時(shi)，就(jiu)增大(da)了電(dian)(dian)(dian)流在線(xian)(xian)路上通過時(shi)的(de)(de)(de)(de)(de)損耗，加劇了電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)的(de)(de)(de)(de)(de)發熱。導(dao)體(ti)(ti)電(dian)(dian)(dian)阻不合(he)格(ge)的(de)(de)(de)(de)(de)原因，主(zhu)要(yao)進企(qi)業為了降低成本，將占原材料成本80%的(de)(de)(de)(de)(de)銅(tong)材縮水，要(yao)么降低導(dao)體(ti)(ti)的(de)(de)(de)(de)(de)截(jie)面(mian)積，要(yao)么使用(yong)含(han)雜質過高(gao)的(de)(de)(de)(de)(de)再生銅(tong)，這樣致使電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)的(de)(de)(de)(de)(de)導(dao)體(ti)(ti)電(dian)(dian)(dian)阻嚴重超標，在使用(yong)過程中(zhong)除易引(yin)發火災，還會加速包(bao)覆在電(dian)(dian)(dian)線(xian)(xian)外的(de)(de)(de)(de)(de)絕緣(yuan)層的(de)(de)(de)(de)(de)老化。

在購買電線(xian)電纜的過程中，消費者應注(zhu)意(yi)以(yi)下幾(ji)個事(shi)

第一、要觀察電線(xian)(xian)的(de)外觀。合(he)格產品的(de)絕緣（護套）層(ceng)柔軟、有(you)韌性(xing)和伸縮(suo)性(xing)、表面層(ceng)緊密(mi)、光滑(hua)、無粗糙感。如果(guo)包裹(guo)電線(xian)(xian)的(de)塑料很容易被(bei)剝去，則存在塑料強度不夠的(de)問(wen)題(ti)。

第二、要看電線的(de)截面。合格產品的(de)銅芯(xin)或(huo)鋁芯(xin)表(biao)面應該具(ju)有(you)金(jin)屬光(guang)澤，表(biao)面發(fa)黑的(de)銅或(huo)表(biao)面發(fa)白的(de)鋁說明(ming)已被氧(yang)化(hua)。

第三、在(zai)購(gou)買電(dian)線時應(ying)注意(yi)查看質(zhi)量(liang)合(he)格證書(shu)。如(ru)果電(dian)線的質(zhi)量(liang)合(he)格，那么其電(dian)線質(zhi)量(liang)應(ying)該(gai)也受過檢驗，不會有太大的問題。
