不合格電線電纜的危害

電(dian)線電(dian)纜是用于傳(chuan)輸電(dian)力、傳(chuan)輸信息和(he)實現電(dian)磁能量轉換的(de)一大(da)類電(dian)工產品(pin)。在抽(chou)查過程中，發(fa)現了大(da)量的(de)不(bu)合(he)格產品(pin)，這些劣質(zhi)產品(pin)給電(dian)力系統(tong)正常運行(xing)埋(mai)下諸(zhu)多隱患。

1、標(biao)(biao)志(zhi)(zhi)不合格的(de)電(dian)線(xian)電(dian)纜(lan)(lan)。標(biao)(biao)志(zhi)(zhi)是電(dian)線(xian)電(dian)纜(lan)(lan)使用識(shi)別(bie)產品(pin)基本信息的(de)主(zhu)要(yao)途徑(jing)，根(gen)據標(biao)(biao)準規定(ding)標(biao)(biao)志(zhi)(zhi)的(de)主(zhu)要(yao)內(nei)容是：產品(pin)型號、規格、標(biao)(biao)準號、廠(chang)名、產地等(deng)在一(yi)定(ding)的(de)標(biao)(biao)示間距內(nei)，當標(biao)(biao)志(zhi)(zhi)不合格時，會造成施工(gong)人員識(shi)別(bie)錯誤，嚴重時會引發電(dian)氣事故。

2、結構尺寸不(bu)(bu)合格的(de)(de)電(dian)線(xian)電(dian)纜(lan)。結構尺寸的(de)(de)主要問題是護套(tao)厚(hou)度(du)，絕(jue)緣(yuan)厚(hou)度(du)，當電(dian)纜(lan)的(de)(de)護套(tao)和絕(jue)緣(yuan)厚(hou)度(du)不(bu)(bu)達(da)標時，致(zhi)使(shi)電(dian)線(xian)電(dian)纜(lan)耐電(dian)氣強度(du)會(hui)嚴重(zhong)降(jiang)低，導(dao)(dao)致(zhi)電(dian)線(xian)電(dian)纜(lan)的(de)(de)使(shi)用壽命縮短，嚴重(zhong)時可(ke)導(dao)(dao)致(zhi)電(dian)線(xian)電(dian)纜(lan)被擊穿，絕(jue)緣(yuan)（護套(tao)）層起不(bu)(bu)到(dao)正常保護作用，從而發生(sheng)電(dian)氣短路和火(huo)災等現(xian)象。

3、護(hu)套式絕(jue)(jue)緣(yuan)老(lao)化前(qian)的抗張強度(du)(du)、伸(shen)長(chang)率合(he)格(ge)的電(dian)線電(dian)纜(lan)。絕(jue)(jue)緣(yuan)護(hu)套老(lao)化前(qian)的抗張強度(du)(du)、伸(shen)長(chang)率不合(he)格(ge)直接大大縮短電(dian)線電(dian)纜(lan)的工作用(yong)壽(shou)命(ming)，而且在(zai)施工或在(zai)長(chang)時間通電(dian)且溫(wen)度(du)(du)較高的環境中，極易出現絕(jue)(jue)緣(yuan)體斷(duan)裂，致使帶電(dian)導體裸(luo)露(lu)，發生(sheng)(sheng)能觸電(dian)式短路危險。其不合(he)格(ge)的主(zhu)要原因是(shi)使用(yong)了再生(sheng)(sheng)料生(sheng)(sheng)產(chan)，以降低產(chan)品成本，二是(shi)不具備(bei)生(sheng)(sheng)產(chan)資格(ge)小型企業。

4、導體(ti)(ti)電(dian)(dian)(dian)阻不合(he)格的(de)(de)(de)(de)電(dian)(dian)(dian)線(xian)。導體(ti)(ti)電(dian)(dian)(dian)阻主(zhu)要(yao)是(shi)考核電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜的(de)(de)(de)(de)導體(ti)(ti)材料以及(ji)截面是(shi)否符合(he)的(de)(de)(de)(de)重要(yao)指標。當導體(ti)(ti)電(dian)(dian)(dian)阻超(chao)標時，就增大了電(dian)(dian)(dian)流在線(xian)路(lu)上通過(guo)(guo)時的(de)(de)(de)(de)損耗(hao)，加(jia)劇了電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜的(de)(de)(de)(de)發熱(re)。導體(ti)(ti)電(dian)(dian)(dian)阻不合(he)格的(de)(de)(de)(de)原因(yin)，主(zhu)要(yao)進企業為了降(jiang)低(di)成本(ben)，將(jiang)占(zhan)原材料成本(ben)80%的(de)(de)(de)(de)銅(tong)材縮水，要(yao)么降(jiang)低(di)導體(ti)(ti)的(de)(de)(de)(de)截面積，要(yao)么使(shi)用(yong)含雜質過(guo)(guo)高(gao)的(de)(de)(de)(de)再生銅(tong)，這樣致使(shi)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜的(de)(de)(de)(de)導體(ti)(ti)電(dian)(dian)(dian)阻嚴重超(chao)標，在使(shi)用(yong)過(guo)(guo)程中除(chu)易(yi)引(yin)發火災，還會加(jia)速包覆在電(dian)(dian)(dian)線(xian)外(wai)的(de)(de)(de)(de)絕緣層的(de)(de)(de)(de)老(lao)化。

在購(gou)買(mai)電(dian)線(xian)電(dian)纜的過程中，消(xiao)費(fei)者(zhe)應(ying)注意以下幾個事

第一(yi)、要(yao)觀察(cha)電線的(de)(de)外觀。合格產品的(de)(de)絕緣(yuan)（護套）層柔軟、有韌性和(he)伸(shen)縮(suo)性、表面(mian)層緊(jin)密、光滑、無粗糙感(gan)。如果包(bao)裹電線的(de)(de)塑料(liao)很(hen)容易(yi)被剝去，則存在塑料(liao)強(qiang)度不夠的(de)(de)問題。

第二、要(yao)看電線的截面(mian)。合(he)格產品的銅芯或鋁芯表(biao)面(mian)應該具有金屬光澤，表(biao)面(mian)發黑(hei)的銅或表(biao)面(mian)發白的鋁說明已被(bei)氧化(hua)。

第三(san)、在購買電線時應(ying)注意查看(kan)質量(liang)合格證書(shu)。如果電線的(de)質量(liang)合格，那么其(qi)電線質量(liang)應(ying)該也受過檢(jian)驗，不(bu)會有太(tai)大的(de)問題(ti)。
