不合格電(dian)(dian)線電(dian)(dian)纜的(de)危害

電(dian)線電(dian)纜是用于傳輸電(dian)力(li)、傳輸信息(xi)和實(shi)現電(dian)磁能量轉換的(de)一大類電(dian)工產(chan)品(pin)。在(zai)抽(chou)查過程中(zhong)，發現了大量的(de)不合(he)格產(chan)品(pin)，這些(xie)劣質產(chan)品(pin)給電(dian)力(li)系統(tong)正常(chang)運行埋下諸多隱(yin)患。

1、標(biao)(biao)志不合格的電線電纜(lan)。標(biao)(biao)志是電線電纜(lan)使用識別(bie)產(chan)品基本信息的主要途(tu)徑，根據標(biao)(biao)準(zhun)規(gui)(gui)定(ding)標(biao)(biao)志的主要內容是：產(chan)品型(xing)號、規(gui)(gui)格、標(biao)(biao)準(zhun)號、廠名、產(chan)地(di)等在一定(ding)的標(biao)(biao)示間距內，當標(biao)(biao)志不合格時(shi)，會(hui)(hui)造成施工人員識別(bie)錯誤，嚴重時(shi)會(hui)(hui)引發(fa)電氣事故(gu)。

2、結(jie)構(gou)尺(chi)寸不(bu)合(he)格的(de)電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)(dian)纜(lan)(lan)。結(jie)構(gou)尺(chi)寸的(de)主要(yao)問題是護套(tao)厚度(du)(du)，絕緣厚度(du)(du)，當電(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)護套(tao)和(he)絕緣厚度(du)(du)不(bu)達標時，致(zhi)(zhi)使電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)(dian)纜(lan)(lan)耐(nai)電(dian)(dian)(dian)(dian)氣強度(du)(du)會嚴重降(jiang)低，導致(zhi)(zhi)電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)使用壽命縮(suo)短，嚴重時可(ke)導致(zhi)(zhi)電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)(dian)纜(lan)(lan)被擊穿，絕緣（護套(tao)）層起不(bu)到正(zheng)常保(bao)護作(zuo)用，從而(er)發生電(dian)(dian)(dian)(dian)氣短路和(he)火災(zai)等現象(xiang)。

3、護套(tao)式(shi)絕(jue)緣(yuan)(yuan)老化(hua)前的抗張強度、伸(shen)長率合格的電(dian)(dian)線電(dian)(dian)纜(lan)。絕(jue)緣(yuan)(yuan)護套(tao)老化(hua)前的抗張強度、伸(shen)長率不(bu)合格直接大(da)大(da)縮短(duan)電(dian)(dian)線電(dian)(dian)纜(lan)的工(gong)作(zuo)用壽(shou)命，而且在(zai)施工(gong)或在(zai)長時間通電(dian)(dian)且溫度較(jiao)高的環境中(zhong)，極(ji)易出現絕(jue)緣(yuan)(yuan)體(ti)斷裂(lie)，致使(shi)帶電(dian)(dian)導(dao)體(ti)裸露，發(fa)生(sheng)能觸電(dian)(dian)式(shi)短(duan)路危險(xian)。其不(bu)合格的主要原因(yin)是使(shi)用了再生(sheng)料(liao)生(sheng)產，以(yi)降低產品成(cheng)本，二是不(bu)具備生(sheng)產資格小型企(qi)業。

4、導(dao)體(ti)(ti)電(dian)(dian)阻不合(he)格的(de)(de)電(dian)(dian)線(xian)。導(dao)體(ti)(ti)電(dian)(dian)阻主要是考核電(dian)(dian)線(xian)電(dian)(dian)纜(lan)的(de)(de)導(dao)體(ti)(ti)材(cai)料(liao)以及(ji)截面是否符合(he)的(de)(de)重(zhong)要指標。當導(dao)體(ti)(ti)電(dian)(dian)阻超標時(shi)(shi)，就增大了電(dian)(dian)流在(zai)線(xian)路(lu)上(shang)通過(guo)時(shi)(shi)的(de)(de)損耗(hao)，加(jia)劇了電(dian)(dian)線(xian)電(dian)(dian)纜(lan)的(de)(de)發熱。導(dao)體(ti)(ti)電(dian)(dian)阻不合(he)格的(de)(de)原因，主要進(jin)企(qi)業(ye)為了降低(di)成本(ben)，將占原材(cai)料(liao)成本(ben)80%的(de)(de)銅(tong)材(cai)縮水，要么降低(di)導(dao)體(ti)(ti)的(de)(de)截面積，要么使用(yong)含雜質過(guo)高的(de)(de)再生銅(tong)，這樣致使電(dian)(dian)線(xian)電(dian)(dian)纜(lan)的(de)(de)導(dao)體(ti)(ti)電(dian)(dian)阻嚴重(zhong)超標，在(zai)使用(yong)過(guo)程中除(chu)易引發火災(zai)，還會加(jia)速(su)包覆在(zai)電(dian)(dian)線(xian)外(wai)的(de)(de)絕緣層的(de)(de)老化(hua)。

在購買電線電纜的過(guo)程中(zhong)，消費(fei)者應注(zhu)意以下幾個事(shi)

第一、要觀察(cha)電線(xian)的(de)外觀。合格產品的(de)絕緣（護套）層柔軟(ruan)、有(you)韌性和伸(shen)縮性、表面層緊(jin)密、光滑、無(wu)粗糙感。如果包裹電線(xian)的(de)塑(su)(su)料很容易被(bei)剝去，則存在塑(su)(su)料強度(du)不夠(gou)的(de)問題(ti)。

第二、要看電線的截(jie)面(mian)。合格(ge)產品(pin)的銅芯(xin)或鋁芯(xin)表面(mian)應該(gai)具有金屬光澤，表面(mian)發黑的銅或表面(mian)發白的鋁說明已被氧(yang)化(hua)。

第三、在購(gou)買電線時(shi)應注意查看(kan)質量(liang)合格證書。如果電線的(de)質量(liang)合格，那(nei)么其電線質量(liang)應該也(ye)受過檢(jian)驗，不會有太大的(de)問題。
