不合(he)格電線電纜的危害

電(dian)線電(dian)纜(lan)是用于傳輸電(dian)力、傳輸信息和實現電(dian)磁(ci)能(neng)量轉換的一大類(lei)電(dian)工產(chan)品。在抽(chou)查過程中，發(fa)現了大量的不(bu)合格產(chan)品，這(zhe)些劣質產(chan)品給電(dian)力系統正常運(yun)行埋(mai)下諸多(duo)隱患。

1、標(biao)志不合(he)格(ge)的電(dian)(dian)線電(dian)(dian)纜。標(biao)志是(shi)電(dian)(dian)線電(dian)(dian)纜使(shi)用識別產品(pin)基(ji)本信息的主(zhu)要(yao)途徑，根(gen)據標(biao)準(zhun)規(gui)定標(biao)志的主(zhu)要(yao)內容是(shi)：產品(pin)型號、規(gui)格(ge)、標(biao)準(zhun)號、廠名、產地等(deng)在一定的標(biao)示間距內，當(dang)標(biao)志不合(he)格(ge)時，會造成施(shi)工(gong)人員(yuan)識別錯(cuo)誤，嚴重時會引發電(dian)(dian)氣事故。

2、結(jie)構(gou)尺(chi)寸不合格的電(dian)線(xian)電(dian)纜(lan)。結(jie)構(gou)尺(chi)寸的主(zhu)要問題(ti)是護(hu)套(tao)厚(hou)度(du)(du)(du)(du)，絕緣厚(hou)度(du)(du)(du)(du)，當電(dian)纜(lan)的護(hu)套(tao)和絕緣厚(hou)度(du)(du)(du)(du)不達標時，致使電(dian)線(xian)電(dian)纜(lan)耐電(dian)氣(qi)(qi)強度(du)(du)(du)(du)會(hui)嚴重(zhong)降低，導致電(dian)線(xian)電(dian)纜(lan)的使用壽(shou)命(ming)縮(suo)短，嚴重(zhong)時可導致電(dian)線(xian)電(dian)纜(lan)被擊穿(chuan)，絕緣（護(hu)套(tao)）層起不到正常(chang)保(bao)護(hu)作用，從而發生電(dian)氣(qi)(qi)短路和火災(zai)等現象。

3、護套式絕(jue)(jue)緣老化前(qian)的(de)(de)抗張強度(du)(du)、伸(shen)(shen)長率合格的(de)(de)電線電纜。絕(jue)(jue)緣護套老化前(qian)的(de)(de)抗張強度(du)(du)、伸(shen)(shen)長率不(bu)合格直接大(da)大(da)縮短(duan)電線電纜的(de)(de)工(gong)作用壽命，而且在(zai)施工(gong)或在(zai)長時間通電且溫度(du)(du)較高的(de)(de)環境中(zhong)，極(ji)易出現絕(jue)(jue)緣體斷裂，致使帶電導(dao)體裸露，發生能觸(chu)電式短(duan)路危險。其不(bu)合格的(de)(de)主要(yao)原因是(shi)使用了(le)再生料生產(chan)，以降(jiang)低(di)產(chan)品(pin)成本，二是(shi)不(bu)具備生產(chan)資(zi)格小型企業(ye)。

4、導(dao)(dao)體(ti)電(dian)(dian)阻不合格的(de)電(dian)(dian)線。導(dao)(dao)體(ti)電(dian)(dian)阻主要是考核(he)電(dian)(dian)線電(dian)(dian)纜(lan)的(de)導(dao)(dao)體(ti)材(cai)(cai)料以及截面是否符合的(de)重(zhong)要指標(biao)。當導(dao)(dao)體(ti)電(dian)(dian)阻超標(biao)時，就增大了(le)電(dian)(dian)流在線路上通過時的(de)損(sun)耗(hao)，加(jia)(jia)劇了(le)電(dian)(dian)線電(dian)(dian)纜(lan)的(de)發(fa)熱。導(dao)(dao)體(ti)電(dian)(dian)阻不合格的(de)原因，主要進企業為了(le)降(jiang)低成本(ben)，將(jiang)占原材(cai)(cai)料成本(ben)80%的(de)銅材(cai)(cai)縮(suo)水，要么降(jiang)低導(dao)(dao)體(ti)的(de)截面積(ji)，要么使(shi)用含雜質過高的(de)再生銅，這樣致使(shi)電(dian)(dian)線電(dian)(dian)纜(lan)的(de)導(dao)(dao)體(ti)電(dian)(dian)阻嚴(yan)重(zhong)超標(biao)，在使(shi)用過程中除易引發(fa)火災，還(huan)會(hui)加(jia)(jia)速包覆在電(dian)(dian)線外的(de)絕緣層的(de)老化。

在購買電線電纜的過(guo)程(cheng)中，消費者應注意(yi)以下幾個事

第一、要(yao)觀察電(dian)線(xian)的(de)(de)外觀。合格產品的(de)(de)絕緣(yuan)（護套(tao)）層柔(rou)軟、有(you)韌性和伸縮性、表面層緊密、光滑、無(wu)粗糙感。如果(guo)包裹電(dian)線(xian)的(de)(de)塑料很容易被剝去，則存在塑料強度(du)不夠(gou)的(de)(de)問題。

第二、要看電線的截面(mian)(mian)。合格(ge)產品的銅芯(xin)或(huo)鋁(lv)芯(xin)表面(mian)(mian)應該具(ju)有金(jin)屬光澤(ze)，表面(mian)(mian)發黑的銅或(huo)表面(mian)(mian)發白的鋁(lv)說明(ming)已被氧化。

第三(san)、在購(gou)買電(dian)線(xian)時應(ying)注意查看質(zhi)量合格證書。如(ru)果電(dian)線(xian)的質(zhi)量合格，那么其電(dian)線(xian)質(zhi)量應(ying)該也受(shou)過(guo)檢驗，不會有太大的問題。
