不(bu)合(he)格(ge)電(dian)線電(dian)纜的危害

電(dian)(dian)線電(dian)(dian)纜(lan)是用于傳(chuan)輸電(dian)(dian)力、傳(chuan)輸信(xin)息和(he)實(shi)現電(dian)(dian)磁(ci)能量(liang)轉換的一大類電(dian)(dian)工產(chan)品。在抽查過程中，發現了大量(liang)的不合格(ge)產(chan)品，這些劣質(zhi)產(chan)品給電(dian)(dian)力系統正常運行埋(mai)下(xia)諸多隱患。

1、標志不合(he)格(ge)的(de)電線電纜。標志是(shi)電線電纜使(shi)用識別(bie)產品基本信息(xi)的(de)主要途徑，根(gen)據標準(zhun)規定標志的(de)主要內容是(shi)：產品型號、規格(ge)、標準(zhun)號、廠名、產地等在一定的(de)標示間距(ju)內，當標志不合(he)格(ge)時，會造(zao)成(cheng)施(shi)工人員識別(bie)錯誤(wu)，嚴重時會引發電氣事故(gu)。

2、結構(gou)尺寸(cun)不(bu)合格的電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)(lan)。結構(gou)尺寸(cun)的主要問題(ti)是(shi)護套厚(hou)度，絕緣(yuan)厚(hou)度，當電(dian)(dian)(dian)纜(lan)(lan)的護套和絕緣(yuan)厚(hou)度不(bu)達標時(shi)，致使(shi)電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)(lan)耐電(dian)(dian)(dian)氣(qi)強度會嚴重降低，導(dao)(dao)致電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)(lan)的使(shi)用壽命縮短，嚴重時(shi)可導(dao)(dao)致電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)(lan)被(bei)擊穿，絕緣(yuan)（護套）層起不(bu)到(dao)正常保(bao)護作用，從而發生電(dian)(dian)(dian)氣(qi)短路和火災等現象。

3、護(hu)套式絕(jue)(jue)緣(yuan)老(lao)化(hua)前的抗張強(qiang)度、伸(shen)(shen)長率合格(ge)的電(dian)線電(dian)纜。絕(jue)(jue)緣(yuan)護(hu)套老(lao)化(hua)前的抗張強(qiang)度、伸(shen)(shen)長率不合格(ge)直接大(da)大(da)縮(suo)短(duan)(duan)電(dian)線電(dian)纜的工作用壽命，而且(qie)(qie)在施(shi)工或在長時間通電(dian)且(qie)(qie)溫(wen)度較高(gao)的環(huan)境(jing)中，極(ji)易(yi)出(chu)現絕(jue)(jue)緣(yuan)體(ti)斷(duan)裂，致(zhi)使(shi)帶(dai)電(dian)導(dao)體(ti)裸露，發生(sheng)(sheng)能觸電(dian)式短(duan)(duan)路危險。其不合格(ge)的主(zhu)要原(yuan)因(yin)是使(shi)用了(le)再生(sheng)(sheng)料生(sheng)(sheng)產(chan)，以(yi)降(jiang)低(di)產(chan)品成(cheng)本，二是不具備生(sheng)(sheng)產(chan)資格(ge)小型企業。

4、導(dao)體(ti)(ti)電(dian)(dian)阻不合(he)格(ge)的(de)(de)(de)(de)電(dian)(dian)線。導(dao)體(ti)(ti)電(dian)(dian)阻主要是考核(he)電(dian)(dian)線電(dian)(dian)纜的(de)(de)(de)(de)導(dao)體(ti)(ti)材料以及截(jie)面是否符合(he)的(de)(de)(de)(de)重要指標。當導(dao)體(ti)(ti)電(dian)(dian)阻超(chao)標時(shi)，就增大了電(dian)(dian)流(liu)在線路上通(tong)過(guo)(guo)時(shi)的(de)(de)(de)(de)損(sun)耗，加劇了電(dian)(dian)線電(dian)(dian)纜的(de)(de)(de)(de)發熱。導(dao)體(ti)(ti)電(dian)(dian)阻不合(he)格(ge)的(de)(de)(de)(de)原因，主要進企(qi)業為了降低成本，將(jiang)占(zhan)原材料成本80%的(de)(de)(de)(de)銅(tong)(tong)材縮水，要么降低導(dao)體(ti)(ti)的(de)(de)(de)(de)截(jie)面積，要么使用含雜質過(guo)(guo)高的(de)(de)(de)(de)再生銅(tong)(tong)，這樣致(zhi)使電(dian)(dian)線電(dian)(dian)纜的(de)(de)(de)(de)導(dao)體(ti)(ti)電(dian)(dian)阻嚴重超(chao)標，在使用過(guo)(guo)程中除易引發火災(zai)，還會加速包(bao)覆(fu)在電(dian)(dian)線外的(de)(de)(de)(de)絕緣層的(de)(de)(de)(de)老化。

在購買電線電纜的(de)過程(cheng)中，消費者應注(zhu)意以下幾個事

第一、要觀察電(dian)(dian)線(xian)的(de)外觀。合格產品(pin)的(de)絕緣（護套）層柔軟、有韌(ren)性和伸縮(suo)性、表面(mian)層緊密(mi)、光滑、無粗(cu)糙感。如果包裹電(dian)(dian)線(xian)的(de)塑料很容易被剝去(qu)，則存(cun)在塑料強度不夠的(de)問題。

第二、要看電線(xian)的(de)截面(mian)。合格產品的(de)銅(tong)芯或鋁芯表(biao)(biao)(biao)面(mian)應該具有(you)金屬光澤，表(biao)(biao)(biao)面(mian)發黑的(de)銅(tong)或表(biao)(biao)(biao)面(mian)發白的(de)鋁說(shuo)明已被氧化。

第三、在(zai)購買電(dian)線時(shi)應注意查(cha)看質量(liang)合(he)格(ge)(ge)證書。如果(guo)電(dian)線的(de)質量(liang)合(he)格(ge)(ge)，那么其電(dian)線質量(liang)應該也受過(guo)檢驗，不會有太大的(de)問(wen)題。
