不合格電線電纜的(de)危害(hai)

電(dian)(dian)(dian)線電(dian)(dian)(dian)纜是(shi)用于傳輸電(dian)(dian)(dian)力(li)(li)、傳輸信息和實現電(dian)(dian)(dian)磁能量(liang)轉換(huan)的(de)一大類電(dian)(dian)(dian)工產品。在(zai)抽查(cha)過程中(zhong)，發(fa)現了大量(liang)的(de)不合(he)格產品，這些劣質產品給電(dian)(dian)(dian)力(li)(li)系統正常運行埋下諸多隱(yin)患。

1、標(biao)(biao)(biao)志(zhi)不(bu)合格(ge)的(de)電(dian)(dian)線(xian)電(dian)(dian)纜。標(biao)(biao)(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(de)主(zhu)要(yao)途徑，根據標(biao)(biao)(biao)準(zhun)規定標(biao)(biao)(biao)志(zhi)的(de)主(zhu)要(yao)內容是：產(chan)品型號(hao)、規格(ge)、標(biao)(biao)(biao)準(zhun)號(hao)、廠(chang)名、產(chan)地等在(zai)一定的(de)標(biao)(biao)(biao)示間距(ju)內，當標(biao)(biao)(biao)志(zhi)不(bu)合格(ge)時，會造成施工人員識(shi)別錯誤，嚴重(zhong)時會引發電(dian)(dian)氣(qi)事故。

2、結構(gou)尺(chi)寸(cun)不(bu)合格的(de)電(dian)線電(dian)纜(lan)。結構(gou)尺(chi)寸(cun)的(de)主要(yao)問題是護(hu)套(tao)厚度，絕(jue)緣(yuan)厚度，當(dang)電(dian)纜(lan)的(de)護(hu)套(tao)和(he)(he)絕(jue)緣(yuan)厚度不(bu)達(da)標時(shi)(shi)，致使電(dian)線電(dian)纜(lan)耐電(dian)氣(qi)強度會嚴重(zhong)降低(di)，導(dao)致電(dian)線電(dian)纜(lan)的(de)使用壽命縮(suo)短(duan)，嚴重(zhong)時(shi)(shi)可導(dao)致電(dian)線電(dian)纜(lan)被擊穿，絕(jue)緣(yuan)（護(hu)套(tao)）層(ceng)起不(bu)到(dao)正常保護(hu)作用，從而發生電(dian)氣(qi)短(duan)路(lu)和(he)(he)火災(zai)等現象。

3、護套式絕緣老化前(qian)的(de)抗(kang)張強(qiang)度(du)、伸長(chang)(chang)率(lv)合格的(de)電線電纜。絕緣護套老化前(qian)的(de)抗(kang)張強(qiang)度(du)、伸長(chang)(chang)率(lv)不合格直(zhi)接大大縮(suo)短(duan)電線電纜的(de)工(gong)作(zuo)用壽命，而且在施(shi)工(gong)或(huo)在長(chang)(chang)時(shi)間通電且溫度(du)較高的(de)環境中，極易出現絕緣體斷裂，致使帶電導體裸(luo)露，發生能觸電式短(duan)路危險。其不合格的(de)主要原因是使用了再(zai)生料生產，以降低(di)產品(pin)成本，二是不具(ju)備生產資格小(xiao)型企(qi)業(ye)。

4、導(dao)(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)阻不(bu)合格(ge)的(de)電(dian)(dian)(dian)線。導(dao)(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)阻主要(yao)是(shi)考核(he)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)的(de)導(dao)(dao)(dao)體(ti)(ti)材料以及(ji)截(jie)面是(shi)否(fou)符合的(de)重(zhong)要(yao)指標。當導(dao)(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)阻超標時，就增大了(le)(le)電(dian)(dian)(dian)流在線路(lu)上(shang)通過時的(de)損耗，加劇了(le)(le)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)的(de)發熱。導(dao)(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)阻不(bu)合格(ge)的(de)原因(yin)，主要(yao)進企(qi)業為(wei)了(le)(le)降低成(cheng)本，將占(zhan)原材料成(cheng)本80%的(de)銅材縮水，要(yao)么降低導(dao)(dao)(dao)體(ti)(ti)的(de)截(jie)面積，要(yao)么使用含雜質(zhi)過高的(de)再生銅，這樣致使電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)的(de)導(dao)(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)阻嚴重(zhong)超標，在使用過程中(zhong)除易引發火災，還會(hui)加速包覆(fu)在電(dian)(dian)(dian)線外的(de)絕(jue)緣層的(de)老(lao)化。

在購買電線電纜的過程中，消(xiao)費者應注意以(yi)下幾個事

第(di)一(yi)、要觀察(cha)電線的(de)外觀。合格產品的(de)絕緣（護套）層柔軟、有韌性(xing)和伸(shen)縮性(xing)、表面(mian)層緊密、光(guang)滑、無粗糙感。如果包裹電線的(de)塑(su)料(liao)很容易(yi)被剝去，則存在塑(su)料(liao)強度不夠的(de)問題。

第二、要看電線(xian)的截面。合(he)格產品的銅(tong)芯或鋁(lv)芯表面應(ying)該具(ju)有金屬光澤，表面發黑的銅(tong)或表面發白的鋁(lv)說明已被氧化。

第(di)三、在購買電線(xian)時應注意查看(kan)質(zhi)量合(he)格證書。如(ru)果電線(xian)的(de)質(zhi)量合(he)格，那么其電線(xian)質(zhi)量應該也受過檢驗(yan)，不會有太大的(de)問題。
