不合格電線電纜的危害

電(dian)(dian)線電(dian)(dian)纜是用于傳輸(shu)電(dian)(dian)力、傳輸(shu)信(xin)息(xi)和(he)實現電(dian)(dian)磁(ci)能量轉換的一大(da)類(lei)電(dian)(dian)工產(chan)品(pin)(pin)。在抽查過程中，發(fa)現了大(da)量的不合格(ge)產(chan)品(pin)(pin)，這些劣質(zhi)產(chan)品(pin)(pin)給電(dian)(dian)力系統正常運(yun)行(xing)埋(mai)下諸(zhu)多隱(yin)患。

1、標(biao)志(zhi)不(bu)合(he)(he)格的電(dian)線(xian)電(dian)纜。標(biao)志(zhi)是電(dian)線(xian)電(dian)纜使用識別產(chan)品基本信息(xi)的主(zhu)要途徑，根據標(biao)準規定(ding)標(biao)志(zhi)的主(zhu)要內容(rong)是：產(chan)品型(xing)號(hao)、規格、標(biao)準號(hao)、廠名、產(chan)地等(deng)在一(yi)定(ding)的標(biao)示間距內，當標(biao)志(zhi)不(bu)合(he)(he)格時(shi)，會造成施工人員識別錯誤(wu)，嚴重時(shi)會引發(fa)電(dian)氣事故。

2、結構尺寸不(bu)合(he)格(ge)的(de)(de)電(dian)(dian)線電(dian)(dian)纜(lan)。結構尺寸的(de)(de)主(zhu)要(yao)問題是護套厚(hou)度，絕(jue)緣(yuan)厚(hou)度，當(dang)電(dian)(dian)纜(lan)的(de)(de)護套和絕(jue)緣(yuan)厚(hou)度不(bu)達標(biao)時，致使電(dian)(dian)線電(dian)(dian)纜(lan)耐電(dian)(dian)氣強(qiang)度會嚴重降低，導致電(dian)(dian)線電(dian)(dian)纜(lan)的(de)(de)使用壽命(ming)縮(suo)短，嚴重時可導致電(dian)(dian)線電(dian)(dian)纜(lan)被擊穿，絕(jue)緣(yuan)（護套）層起(qi)不(bu)到(dao)正常保護作用，從(cong)而發生電(dian)(dian)氣短路和火災(zai)等現象(xiang)。

3、護套(tao)式(shi)絕(jue)緣(yuan)老(lao)(lao)化(hua)前的(de)(de)抗張強度、伸長率(lv)合格的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)(dian)(dian)纜。絕(jue)緣(yuan)護套(tao)老(lao)(lao)化(hua)前的(de)(de)抗張強度、伸長率(lv)不(bu)合格直接大大縮短(duan)電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)(dian)(dian)纜的(de)(de)工(gong)(gong)作用壽(shou)命(ming)，而且在施(shi)工(gong)(gong)或在長時間通電(dian)(dian)(dian)(dian)(dian)(dian)且溫度較高(gao)的(de)(de)環境中，極(ji)易出現絕(jue)緣(yuan)體斷裂(lie)，致使帶電(dian)(dian)(dian)(dian)(dian)(dian)導體裸露，發(fa)生(sheng)能(neng)觸(chu)電(dian)(dian)(dian)(dian)(dian)(dian)式(shi)短(duan)路危險。其(qi)不(bu)合格的(de)(de)主要原因是(shi)使用了再生(sheng)料生(sheng)產，以降低產品成本，二是(shi)不(bu)具備生(sheng)產資格小型企業(ye)。

4、導(dao)(dao)體電(dian)(dian)(dian)(dian)阻不(bu)合格的(de)(de)(de)電(dian)(dian)(dian)(dian)線(xian)(xian)。導(dao)(dao)體電(dian)(dian)(dian)(dian)阻主(zhu)要(yao)是考(kao)核(he)電(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)纜(lan)的(de)(de)(de)導(dao)(dao)體材料以及截(jie)面是否符合的(de)(de)(de)重要(yao)指標。當導(dao)(dao)體電(dian)(dian)(dian)(dian)阻超標時，就增大了電(dian)(dian)(dian)(dian)流在(zai)線(xian)(xian)路上通過(guo)(guo)時的(de)(de)(de)損(sun)耗，加(jia)劇了電(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)纜(lan)的(de)(de)(de)發(fa)熱。導(dao)(dao)體電(dian)(dian)(dian)(dian)阻不(bu)合格的(de)(de)(de)原(yuan)因(yin)，主(zhu)要(yao)進企(qi)業為(wei)了降低成(cheng)本，將(jiang)占原(yuan)材料成(cheng)本80%的(de)(de)(de)銅材縮水，要(yao)么(me)降低導(dao)(dao)體的(de)(de)(de)截(jie)面積，要(yao)么(me)使(shi)用含雜質過(guo)(guo)高的(de)(de)(de)再生銅，這樣致使(shi)電(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)纜(lan)的(de)(de)(de)導(dao)(dao)體電(dian)(dian)(dian)(dian)阻嚴重超標，在(zai)使(shi)用過(guo)(guo)程中除易引發(fa)火災，還(huan)會加(jia)速包覆在(zai)電(dian)(dian)(dian)(dian)線(xian)(xian)外(wai)的(de)(de)(de)絕緣層的(de)(de)(de)老化。

在購買電(dian)線電(dian)纜的過程中，消(xiao)費者(zhe)應注意以下幾個事

第(di)一、要觀察電線的(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(mi)、光滑、無粗糙感。如果包裹(guo)電線的(de)塑(su)料很容易被剝去，則存在塑(su)料強度(du)不夠的(de)問題。

第二、要看電線的截面(mian)。合(he)格產品的銅芯(xin)或鋁芯(xin)表(biao)(biao)面(mian)應該具有(you)金屬光澤，表(biao)(biao)面(mian)發黑的銅或表(biao)(biao)面(mian)發白的鋁說(shuo)明已被(bei)氧化。

第三、在購(gou)買電線(xian)時(shi)應(ying)注意(yi)查看質量(liang)合格證書(shu)。如果(guo)電線(xian)的質量(liang)合格，那么其電線(xian)質量(liang)應(ying)該(gai)也受(shou)過檢驗，不(bu)會有太大的問題。
