不合格電線電纜的危害

電(dian)線電(dian)纜是(shi)用(yong)于傳輸(shu)電(dian)力(li)、傳輸(shu)信息和(he)實現(xian)電(dian)磁能(neng)量(liang)轉換的一(yi)大類電(dian)工產(chan)品。在抽查過(guo)程中，發現(xian)了大量(liang)的不合格產(chan)品，這些劣(lie)質產(chan)品給電(dian)力(li)系(xi)統正常(chang)運行(xing)埋下諸多隱(yin)患。

1、標(biao)志(zhi)(zhi)(zhi)不合格的(de)電(dian)線(xian)電(dian)纜(lan)。標(biao)志(zhi)(zhi)(zhi)是電(dian)線(xian)電(dian)纜(lan)使用識別(bie)產品基(ji)本信息的(de)主(zhu)要途徑，根(gen)據(ju)標(biao)準(zhun)規定標(biao)志(zhi)(zhi)(zhi)的(de)主(zhu)要內容是：產品型號(hao)、規格、標(biao)準(zhun)號(hao)、廠名、產地等在(zai)一定的(de)標(biao)示間(jian)距內，當標(biao)志(zhi)(zhi)(zhi)不合格時，會(hui)造成施工人員識別(bie)錯誤，嚴重時會(hui)引發(fa)電(dian)氣事故(gu)。

2、結構(gou)尺寸(cun)不合格的(de)(de)電(dian)線(xian)(xian)電(dian)纜。結構(gou)尺寸(cun)的(de)(de)主要問題是護套厚度，絕緣厚度，當電(dian)纜的(de)(de)護套和(he)絕緣厚度不達(da)標(biao)時，致使(shi)(shi)電(dian)線(xian)(xian)電(dian)纜耐(nai)電(dian)氣(qi)強(qiang)度會嚴重降低，導致電(dian)線(xian)(xian)電(dian)纜的(de)(de)使(shi)(shi)用(yong)壽命縮短，嚴重時可導致電(dian)線(xian)(xian)電(dian)纜被擊穿，絕緣（護套）層起不到正常保護作(zuo)用(yong)，從而(er)發生電(dian)氣(qi)短路和(he)火災等現象。

3、護(hu)套式(shi)絕(jue)緣老化前的抗張(zhang)強(qiang)度、伸長(chang)(chang)率(lv)合(he)(he)格的電線電纜(lan)。絕(jue)緣護(hu)套老化前的抗張(zhang)強(qiang)度、伸長(chang)(chang)率(lv)不合(he)(he)格直接(jie)大大縮短電線電纜(lan)的工作用(yong)壽命，而且在(zai)施(shi)工或(huo)在(zai)長(chang)(chang)時間通電且溫(wen)度較高的環境中，極(ji)易出現(xian)絕(jue)緣體斷裂，致使帶電導體裸露(lu)，發生(sheng)能(neng)觸電式(shi)短路危險。其不合(he)(he)格的主要原因是使用(yong)了(le)再生(sheng)料生(sheng)產，以降低產品(pin)成本，二(er)是不具備生(sheng)產資(zi)格小型企業。

4、導(dao)體(ti)電(dian)(dian)阻(zu)(zu)(zu)不合格的(de)電(dian)(dian)線(xian)(xian)(xian)(xian)。導(dao)體(ti)電(dian)(dian)阻(zu)(zu)(zu)主要(yao)是(shi)考核電(dian)(dian)線(xian)(xian)(xian)(xian)電(dian)(dian)纜(lan)的(de)導(dao)體(ti)材料(liao)以及截(jie)面是(shi)否符合的(de)重(zhong)要(yao)指標(biao)。當導(dao)體(ti)電(dian)(dian)阻(zu)(zu)(zu)超標(biao)時，就增大了電(dian)(dian)流在線(xian)(xian)(xian)(xian)路上(shang)通過時的(de)損耗，加(jia)(jia)劇(ju)了電(dian)(dian)線(xian)(xian)(xian)(xian)電(dian)(dian)纜(lan)的(de)發熱。導(dao)體(ti)電(dian)(dian)阻(zu)(zu)(zu)不合格的(de)原因，主要(yao)進企業為(wei)了降(jiang)低成(cheng)本，將占(zhan)原材料(liao)成(cheng)本80%的(de)銅材縮水，要(yao)么降(jiang)低導(dao)體(ti)的(de)截(jie)面積，要(yao)么使(shi)用(yong)(yong)含雜(za)質過高的(de)再生銅，這樣致使(shi)電(dian)(dian)線(xian)(xian)(xian)(xian)電(dian)(dian)纜(lan)的(de)導(dao)體(ti)電(dian)(dian)阻(zu)(zu)(zu)嚴重(zhong)超標(biao)，在使(shi)用(yong)(yong)過程中除易(yi)引發火災，還會加(jia)(jia)速包覆在電(dian)(dian)線(xian)(xian)(xian)(xian)外(wai)的(de)絕緣層的(de)老(lao)化(hua)。

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

第一、要(yao)觀察電線(xian)的(de)(de)外(wai)觀。合格產品的(de)(de)絕緣（護套）層(ceng)柔軟、有韌性和伸(shen)縮性、表面層(ceng)緊密、光(guang)滑、無粗糙感。如果包(bao)裹電線(xian)的(de)(de)塑(su)料很容(rong)易被剝去，則存在塑(su)料強度不夠的(de)(de)問題(ti)。

第二、要看(kan)電線的(de)(de)截面。合格產(chan)品(pin)的(de)(de)銅芯(xin)或(huo)鋁芯(xin)表(biao)面應該具有金屬光澤，表(biao)面發黑的(de)(de)銅或(huo)表(biao)面發白的(de)(de)鋁說(shuo)明(ming)已被氧(yang)化。

第三、在(zai)購買電線時(shi)應注意查(cha)看質(zhi)量合格(ge)證(zheng)書。如果電線的(de)質(zhi)量合格(ge)，那么其電線質(zhi)量應該也(ye)受過檢驗，不會有太大的(de)問(wen)題。
