不合格電(dian)線(xian)電(dian)纜(lan)的危(wei)害

電(dian)(dian)線電(dian)(dian)纜是用于(yu)傳輸電(dian)(dian)力(li)、傳輸信息和實現電(dian)(dian)磁能量轉(zhuan)換的一大(da)類電(dian)(dian)工產(chan)品。在抽查過程中，發現了(le)大(da)量的不合格產(chan)品，這些劣(lie)質(zhi)產(chan)品給(gei)電(dian)(dian)力(li)系統(tong)正常(chang)運行埋下諸多(duo)隱(yin)患。

1、標(biao)志(zhi)不(bu)合(he)格的電(dian)(dian)線(xian)電(dian)(dian)纜。標(biao)志(zhi)是電(dian)(dian)線(xian)電(dian)(dian)纜使用識(shi)別產(chan)品基本(ben)信息的主要途徑(jing)，根據標(biao)準規定(ding)標(biao)志(zhi)的主要內容是：產(chan)品型號、規格、標(biao)準號、廠名、產(chan)地等(deng)在一定(ding)的標(biao)示間距內，當標(biao)志(zhi)不(bu)合(he)格時，會造成施工(gong)人員識(shi)別錯誤，嚴重(zhong)時會引發(fa)電(dian)(dian)氣事故。

2、結(jie)構(gou)尺寸不(bu)合格的(de)電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)。結(jie)構(gou)尺寸的(de)主要問題是護套厚度，絕(jue)緣(yuan)厚度，當電(dian)(dian)(dian)(dian)纜(lan)的(de)護套和絕(jue)緣(yuan)厚度不(bu)達標時，致使電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)耐電(dian)(dian)(dian)(dian)氣(qi)強度會嚴重降(jiang)低，導(dao)致電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)的(de)使用壽命縮短，嚴重時可導(dao)致電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)被(bei)擊穿，絕(jue)緣(yuan)（護套）層(ceng)起不(bu)到正常保護作(zuo)用，從而發生(sheng)電(dian)(dian)(dian)(dian)氣(qi)短路和火災等現象。

3、護套(tao)式(shi)絕緣(yuan)老(lao)化前的(de)(de)抗張強度、伸長率(lv)合(he)格(ge)(ge)的(de)(de)電線電纜(lan)。絕緣(yuan)護套(tao)老(lao)化前的(de)(de)抗張強度、伸長率(lv)不合(he)格(ge)(ge)直(zhi)接大(da)大(da)縮短(duan)電線電纜(lan)的(de)(de)工(gong)作用壽命(ming)，而且在(zai)施工(gong)或在(zai)長時間通電且溫度較高的(de)(de)環(huan)境(jing)中，極易出現絕緣(yuan)體(ti)(ti)斷裂，致(zhi)使帶電導(dao)體(ti)(ti)裸露，發(fa)生能觸電式(shi)短(duan)路危(wei)險。其不合(he)格(ge)(ge)的(de)(de)主要(yao)原因是使用了再生料生產，以(yi)降低產品成(cheng)本，二是不具備(bei)生產資格(ge)(ge)小型企業(ye)。

4、導(dao)(dao)(dao)體(ti)電(dian)阻(zu)(zu)(zu)不(bu)合格(ge)的(de)(de)電(dian)線。導(dao)(dao)(dao)體(ti)電(dian)阻(zu)(zu)(zu)主(zhu)要(yao)是考核電(dian)線電(dian)纜的(de)(de)導(dao)(dao)(dao)體(ti)材料(liao)以及截面是否符合的(de)(de)重(zhong)要(yao)指標(biao)。當(dang)導(dao)(dao)(dao)體(ti)電(dian)阻(zu)(zu)(zu)超(chao)標(biao)時，就增大了(le)(le)電(dian)流在(zai)線路上通過時的(de)(de)損耗(hao)，加(jia)劇了(le)(le)電(dian)線電(dian)纜的(de)(de)發熱。導(dao)(dao)(dao)體(ti)電(dian)阻(zu)(zu)(zu)不(bu)合格(ge)的(de)(de)原(yuan)因(yin)，主(zhu)要(yao)進企業為了(le)(le)降(jiang)低成(cheng)本(ben)，將占(zhan)原(yuan)材料(liao)成(cheng)本(ben)80%的(de)(de)銅材縮水，要(yao)么(me)降(jiang)低導(dao)(dao)(dao)體(ti)的(de)(de)截面積，要(yao)么(me)使用(yong)(yong)含雜質過高的(de)(de)再生銅，這(zhe)樣(yang)致使電(dian)線電(dian)纜的(de)(de)導(dao)(dao)(dao)體(ti)電(dian)阻(zu)(zu)(zu)嚴重(zhong)超(chao)標(biao)，在(zai)使用(yong)(yong)過程中除易(yi)引發火災，還會加(jia)速包覆在(zai)電(dian)線外的(de)(de)絕緣層的(de)(de)老化(hua)。

在購買電線電纜的過程中，消費者(zhe)應注意以(yi)下(xia)幾個事

第一、要觀察電線的外觀。合格產(chan)品的絕緣（護套）層(ceng)柔軟、有(you)韌性和伸縮性、表面(mian)層(ceng)緊(jin)密、光滑、無粗糙感。如(ru)果包裹(guo)電線的塑(su)料(liao)很容(rong)易被剝去，則存在塑(su)料(liao)強度不夠的問題。

第二、要看(kan)電(dian)線(xian)的(de)截面(mian)。合格產(chan)品的(de)銅芯(xin)或(huo)鋁芯(xin)表(biao)面(mian)應(ying)該具有金屬光澤，表(biao)面(mian)發(fa)黑的(de)銅或(huo)表(biao)面(mian)發(fa)白的(de)鋁說明已被(bei)氧化(hua)。

第三、在(zai)購買(mai)電線(xian)時(shi)應注意查(cha)看質(zhi)量(liang)合(he)格證書。如果電線(xian)的(de)質(zhi)量(liang)合(he)格，那么其電線(xian)質(zhi)量(liang)應該也受(shou)過檢驗(yan)，不會(hui)有(you)太大的(de)問題(ti)。
