不合格電線電纜(lan)的危害

電(dian)(dian)線(xian)電(dian)(dian)纜是(shi)用于傳(chuan)輸電(dian)(dian)力(li)、傳(chuan)輸信息(xi)和實現(xian)電(dian)(dian)磁能量轉換的一大(da)類電(dian)(dian)工產品。在抽(chou)查過程中(zhong)，發現(xian)了大(da)量的不(bu)合格(ge)產品，這些劣質產品給電(dian)(dian)力(li)系統正常運(yun)行(xing)埋下(xia)諸(zhu)多隱患。

1、標(biao)志(zhi)(zhi)不合(he)(he)格(ge)(ge)的電(dian)線(xian)電(dian)纜。標(biao)志(zhi)(zhi)是電(dian)線(xian)電(dian)纜使用識(shi)別產品(pin)基本信息的主(zhu)要途徑，根據標(biao)準(zhun)規定標(biao)志(zhi)(zhi)的主(zhu)要內容(rong)是：產品(pin)型號(hao)、規格(ge)(ge)、標(biao)準(zhun)號(hao)、廠名、產地等在一定的標(biao)示間距內，當標(biao)志(zhi)(zhi)不合(he)(he)格(ge)(ge)時，會(hui)造(zao)成(cheng)施工人員識(shi)別錯(cuo)誤，嚴(yan)重(zhong)時會(hui)引發(fa)電(dian)氣事故。

2、結構尺寸不(bu)合(he)格的(de)(de)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)(lan)。結構尺寸的(de)(de)主要(yao)問題是護(hu)套(tao)厚度(du)，絕(jue)緣(yuan)厚度(du)，當電(dian)(dian)(dian)纜(lan)(lan)的(de)(de)護(hu)套(tao)和絕(jue)緣(yuan)厚度(du)不(bu)達標時，致(zhi)使電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)(lan)耐電(dian)(dian)(dian)氣(qi)強度(du)會嚴重降(jiang)低，導致(zhi)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)(lan)的(de)(de)使用壽命縮(suo)短，嚴重時可導致(zhi)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)(lan)被擊穿(chuan)，絕(jue)緣(yuan)（護(hu)套(tao)）層起不(bu)到正常保護(hu)作用，從(cong)而發生(sheng)電(dian)(dian)(dian)氣(qi)短路和火災等現象(xiang)。

3、護套式絕(jue)(jue)緣(yuan)(yuan)老(lao)化前的抗(kang)張(zhang)強(qiang)度(du)、伸(shen)長率(lv)(lv)合格(ge)的電(dian)線(xian)電(dian)纜。絕(jue)(jue)緣(yuan)(yuan)護套老(lao)化前的抗(kang)張(zhang)強(qiang)度(du)、伸(shen)長率(lv)(lv)不合格(ge)直(zhi)接大大縮(suo)短(duan)電(dian)線(xian)電(dian)纜的工(gong)(gong)作用壽命，而(er)且(qie)在施工(gong)(gong)或在長時(shi)間通電(dian)且(qie)溫度(du)較高的環境中，極易出(chu)現絕(jue)(jue)緣(yuan)(yuan)體斷裂(lie)，致使帶電(dian)導(dao)體裸露，發生(sheng)能觸電(dian)式短(duan)路(lu)危險。其不合格(ge)的主要原(yuan)因是使用了再生(sheng)料生(sheng)產，以降(jiang)低(di)產品(pin)成本(ben)，二(er)是不具備(bei)生(sheng)產資格(ge)小型企業。

4、導體(ti)電(dian)阻(zu)不合格(ge)的(de)(de)(de)(de)電(dian)線。導體(ti)電(dian)阻(zu)主要(yao)(yao)是考核電(dian)線電(dian)纜的(de)(de)(de)(de)導體(ti)材(cai)(cai)料(liao)以及截(jie)面是否符合的(de)(de)(de)(de)重要(yao)(yao)指標(biao)。當導體(ti)電(dian)阻(zu)超(chao)標(biao)時，就(jiu)增大了(le)(le)電(dian)流在線路上(shang)通過(guo)時的(de)(de)(de)(de)損耗(hao)，加(jia)(jia)劇了(le)(le)電(dian)線電(dian)纜的(de)(de)(de)(de)發熱。導體(ti)電(dian)阻(zu)不合格(ge)的(de)(de)(de)(de)原(yuan)因，主要(yao)(yao)進企業為了(le)(le)降(jiang)低(di)(di)成(cheng)本(ben)，將占原(yuan)材(cai)(cai)料(liao)成(cheng)本(ben)80%的(de)(de)(de)(de)銅材(cai)(cai)縮水，要(yao)(yao)么(me)降(jiang)低(di)(di)導體(ti)的(de)(de)(de)(de)截(jie)面積，要(yao)(yao)么(me)使(shi)用含雜質過(guo)高的(de)(de)(de)(de)再(zai)生銅，這(zhe)樣致使(shi)電(dian)線電(dian)纜的(de)(de)(de)(de)導體(ti)電(dian)阻(zu)嚴重超(chao)標(biao)，在使(shi)用過(guo)程(cheng)中(zhong)除(chu)易引發火災，還會(hui)加(jia)(jia)速包覆在電(dian)線外的(de)(de)(de)(de)絕(jue)緣層的(de)(de)(de)(de)老(lao)化。

在購買電線電纜的過程中(zhong)，消費者應(ying)注(zhu)意以下幾個事

第一、要(yao)觀(guan)察電線的(de)外觀(guan)。合格產品的(de)絕緣(yuan)（護套）層柔軟、有韌性(xing)和伸縮性(xing)、表面層緊密、光滑、無粗糙感。如果(guo)包裹電線的(de)塑料很(hen)容易被剝去，則存在塑料強(qiang)度不夠(gou)的(de)問題。

第二、要(yao)看電線的(de)(de)截面(mian)。合(he)格產(chan)品的(de)(de)銅(tong)芯或鋁芯表面(mian)應該具有(you)金(jin)屬(shu)光澤，表面(mian)發黑的(de)(de)銅(tong)或表面(mian)發白的(de)(de)鋁說明已(yi)被氧(yang)化。

第三(san)、在購買電線時(shi)應注意查看(kan)質量合格證書。如(ru)果(guo)電線的(de)質量合格，那么其電線質量應該也受(shou)過檢驗，不會有太大(da)的(de)問題。
