不合格電線電纜(lan)的危害

電線電纜是用于傳輸電力、傳輸信息和實現電磁能量轉換的(de)一(yi)大類(lei)電工產品。在(zai)抽查過程中，發現了大量的(de)不合(he)格產品，這些劣質產品給電力系統正常運行埋下諸多隱患。

1、標志(zhi)(zhi)不(bu)合格(ge)的(de)(de)(de)電線電纜。標志(zhi)(zhi)是電線電纜使(shi)用識(shi)別(bie)產品基(ji)本(ben)信息(xi)的(de)(de)(de)主要(yao)途徑，根據標準(zhun)規定標志(zhi)(zhi)的(de)(de)(de)主要(yao)內容是：產品型號、規格(ge)、標準(zhun)號、廠名、產地等在一(yi)定的(de)(de)(de)標示間距內，當標志(zhi)(zhi)不(bu)合格(ge)時，會造成施工人員(yuan)識(shi)別(bie)錯誤，嚴重時會引發電氣事(shi)故。

2、結(jie)構尺(chi)寸不合(he)格的電(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)纜。結(jie)構尺(chi)寸的主要(yao)問題是護套厚度，絕(jue)緣(yuan)厚度，當電(dian)(dian)(dian)纜的護套和絕(jue)緣(yuan)厚度不達標時，致使電(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)纜耐電(dian)(dian)(dian)氣強度會(hui)嚴重(zhong)降低，導致電(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)纜的使用(yong)壽命縮短，嚴重(zhong)時可導致電(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)纜被擊穿，絕(jue)緣(yuan)（護套）層起不到正常保護作(zuo)用(yong)，從(cong)而發(fa)生(sheng)電(dian)(dian)(dian)氣短路和火災(zai)等現象。

3、護套(tao)式絕緣(yuan)老化前的(de)(de)(de)抗張強度、伸長率合(he)格(ge)的(de)(de)(de)電(dian)線電(dian)纜。絕緣(yuan)護套(tao)老化前的(de)(de)(de)抗張強度、伸長率不合(he)格(ge)直接(jie)大大縮短電(dian)線電(dian)纜的(de)(de)(de)工作用壽命，而且(qie)在(zai)施工或在(zai)長時間通(tong)電(dian)且(qie)溫度較高的(de)(de)(de)環境中，極易出現絕緣(yuan)體斷裂，致使(shi)帶電(dian)導(dao)體裸(luo)露(lu)，發生(sheng)(sheng)能觸電(dian)式短路危(wei)險。其不合(he)格(ge)的(de)(de)(de)主(zhu)要(yao)原因是(shi)(shi)使(shi)用了再生(sheng)(sheng)料生(sheng)(sheng)產，以降(jiang)低產品成(cheng)本，二(er)是(shi)(shi)不具備生(sheng)(sheng)產資格(ge)小型企業。

4、導(dao)(dao)(dao)(dao)體(ti)電(dian)(dian)(dian)(dian)阻(zu)不合(he)格的電(dian)(dian)(dian)(dian)線(xian)。導(dao)(dao)(dao)(dao)體(ti)電(dian)(dian)(dian)(dian)阻(zu)主要(yao)(yao)是考核電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)的導(dao)(dao)(dao)(dao)體(ti)材(cai)(cai)料(liao)以及截(jie)(jie)面是否符合(he)的重(zhong)要(yao)(yao)指標(biao)。當導(dao)(dao)(dao)(dao)體(ti)電(dian)(dian)(dian)(dian)阻(zu)超標(biao)時，就增(zeng)大了電(dian)(dian)(dian)(dian)流在線(xian)路(lu)上(shang)通過(guo)時的損耗，加劇(ju)了電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)的發(fa)熱。導(dao)(dao)(dao)(dao)體(ti)電(dian)(dian)(dian)(dian)阻(zu)不合(he)格的原因，主要(yao)(yao)進企業(ye)為(wei)了降低成本(ben)(ben)，將占原材(cai)(cai)料(liao)成本(ben)(ben)80%的銅材(cai)(cai)縮水，要(yao)(yao)么(me)降低導(dao)(dao)(dao)(dao)體(ti)的截(jie)(jie)面積，要(yao)(yao)么(me)使用(yong)含雜質過(guo)高(gao)的再生銅，這(zhe)樣致使電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)的導(dao)(dao)(dao)(dao)體(ti)電(dian)(dian)(dian)(dian)阻(zu)嚴重(zhong)超標(biao)，在使用(yong)過(guo)程中除易引發(fa)火災，還會加速包覆在電(dian)(dian)(dian)(dian)線(xian)外的絕緣(yuan)層的老化。

在購買電(dian)線電(dian)纜的過程中，消費者應注意以(yi)下幾個(ge)事

第一、要觀察電線的(de)外(wai)觀。合格產品的(de)絕緣（護套）層(ceng)柔軟、有韌性和(he)伸(shen)縮性、表面層(ceng)緊(jin)密、光滑、無粗糙感。如果包裹電線的(de)塑料很容易(yi)被剝去(qu)，則存在塑料強(qiang)度不夠(gou)的(de)問題。

第二、要看電線的(de)(de)截(jie)面(mian)。合格產(chan)品的(de)(de)銅芯或(huo)鋁(lv)芯表面(mian)應該(gai)具(ju)有(you)金屬光澤(ze)，表面(mian)發黑的(de)(de)銅或(huo)表面(mian)發白的(de)(de)鋁(lv)說明已被氧化(hua)。

第三、在購買電(dian)線時(shi)應(ying)注意(yi)查(cha)看質量合(he)格(ge)證書。如果電(dian)線的質量合(he)格(ge)，那么其電(dian)線質量應(ying)該也受過(guo)檢(jian)驗，不會有太大的問題。
