不合格電線電纜的危(wei)害

電(dian)(dian)線電(dian)(dian)纜是用于傳(chuan)輸(shu)電(dian)(dian)力、傳(chuan)輸(shu)信息和實現(xian)電(dian)(dian)磁能量(liang)(liang)轉換的一大(da)類(lei)電(dian)(dian)工產(chan)品。在抽查過(guo)程中，發現(xian)了大(da)量(liang)(liang)的不合(he)格(ge)產(chan)品，這些劣質產(chan)品給電(dian)(dian)力系統正(zheng)常(chang)運行埋下諸(zhu)多隱患。

1、標志不(bu)合格的電(dian)線(xian)電(dian)纜(lan)(lan)。標志是(shi)電(dian)線(xian)電(dian)纜(lan)(lan)使用識別(bie)產(chan)品基(ji)本(ben)信息的主(zhu)要途徑，根(gen)據(ju)標準(zhun)(zhun)規定標志的主(zhu)要內容是(shi)：產(chan)品型號(hao)、規格、標準(zhun)(zhun)號(hao)、廠名、產(chan)地(di)等在一(yi)定的標示間距內，當標志不(bu)合格時(shi)，會造成施工人員(yuan)識別(bie)錯誤，嚴重時(shi)會引(yin)發電(dian)氣事故(gu)。

2、結(jie)構尺(chi)寸(cun)不合格的(de)(de)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)。結(jie)構尺(chi)寸(cun)的(de)(de)主要問題是護(hu)(hu)套(tao)厚度，絕緣厚度，當電(dian)(dian)(dian)纜(lan)的(de)(de)護(hu)(hu)套(tao)和(he)絕緣厚度不達(da)標(biao)時(shi)，致(zhi)使(shi)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)耐電(dian)(dian)(dian)氣(qi)強度會嚴重降低，導(dao)致(zhi)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)的(de)(de)使(shi)用壽命(ming)縮短(duan)，嚴重時(shi)可導(dao)致(zhi)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)被擊(ji)穿，絕緣（護(hu)(hu)套(tao)）層起不到正常保護(hu)(hu)作用，從而發生電(dian)(dian)(dian)氣(qi)短(duan)路(lu)和(he)火災等(deng)現象。

3、護套式絕(jue)(jue)緣(yuan)老(lao)化前(qian)的(de)抗張強度(du)、伸長率合(he)格(ge)的(de)電線(xian)電纜。絕(jue)(jue)緣(yuan)護套老(lao)化前(qian)的(de)抗張強度(du)、伸長率不合(he)格(ge)直接大大縮短電線(xian)電纜的(de)工作用(yong)壽(shou)命，而且(qie)在(zai)施工或在(zai)長時間(jian)通電且(qie)溫度(du)較高的(de)環境(jing)中(zhong)，極易出(chu)現絕(jue)(jue)緣(yuan)體(ti)斷裂，致使(shi)帶電導體(ti)裸露，發生(sheng)(sheng)能觸電式短路危險(xian)。其(qi)不合(he)格(ge)的(de)主要原因是(shi)使(shi)用(yong)了(le)再(zai)生(sheng)(sheng)料(liao)生(sheng)(sheng)產，以降低產品成本(ben)，二是(shi)不具(ju)備(bei)生(sheng)(sheng)產資格(ge)小型企業(ye)。

4、導(dao)體(ti)電(dian)(dian)(dian)阻(zu)(zu)(zu)不合(he)格(ge)的(de)(de)(de)(de)電(dian)(dian)(dian)線。導(dao)體(ti)電(dian)(dian)(dian)阻(zu)(zu)(zu)主(zhu)要是考核電(dian)(dian)(dian)線電(dian)(dian)(dian)纜的(de)(de)(de)(de)導(dao)體(ti)材(cai)(cai)料以及截(jie)面是否符合(he)的(de)(de)(de)(de)重(zhong)(zhong)要指標(biao)(biao)。當導(dao)體(ti)電(dian)(dian)(dian)阻(zu)(zu)(zu)超(chao)標(biao)(biao)時(shi)，就增大了電(dian)(dian)(dian)流在(zai)(zai)線路上(shang)通過時(shi)的(de)(de)(de)(de)損耗(hao)，加劇了電(dian)(dian)(dian)線電(dian)(dian)(dian)纜的(de)(de)(de)(de)發熱。導(dao)體(ti)電(dian)(dian)(dian)阻(zu)(zu)(zu)不合(he)格(ge)的(de)(de)(de)(de)原因(yin)，主(zhu)要進企業為了降(jiang)低成本，將占原材(cai)(cai)料成本80%的(de)(de)(de)(de)銅材(cai)(cai)縮水，要么(me)降(jiang)低導(dao)體(ti)的(de)(de)(de)(de)截(jie)面積，要么(me)使用含雜(za)質(zhi)過高(gao)的(de)(de)(de)(de)再生銅，這樣致使電(dian)(dian)(dian)線電(dian)(dian)(dian)纜的(de)(de)(de)(de)導(dao)體(ti)電(dian)(dian)(dian)阻(zu)(zu)(zu)嚴(yan)重(zhong)(zhong)超(chao)標(biao)(biao)，在(zai)(zai)使用過程(cheng)中除易引(yin)發火災，還(huan)會(hui)加速包覆在(zai)(zai)電(dian)(dian)(dian)線外的(de)(de)(de)(de)絕(jue)緣層的(de)(de)(de)(de)老化。

在購買電線(xian)電纜(lan)的(de)過(guo)程(cheng)中，消費(fei)者應注意以下幾個事

第一(yi)、要觀察(cha)電(dian)線(xian)的(de)外觀。合(he)格(ge)產品的(de)絕(jue)緣(yuan)（護套(tao)）層(ceng)柔軟、有(you)韌性和伸縮性、表面層(ceng)緊密、光滑、無粗糙感。如果包裹電(dian)線(xian)的(de)塑料(liao)很(hen)容(rong)易被剝(bo)去，則存在塑料(liao)強度不夠的(de)問題。

第二、要(yao)看電線的(de)截面。合格產品的(de)銅芯或(huo)鋁芯表(biao)面應該具有金(jin)屬光澤，表(biao)面發黑的(de)銅或(huo)表(biao)面發白的(de)鋁說明已被氧化(hua)。

第三、在購買電線(xian)時(shi)應(ying)注意查看(kan)質(zhi)量(liang)合(he)格證書。如果(guo)電線(xian)的質(zhi)量(liang)合(he)格，那么其電線(xian)質(zhi)量(liang)應(ying)該也受過(guo)檢驗(yan)，不會有太大的問(wen)題。
