不合(he)格電線電纜的危害

電(dian)(dian)(dian)線電(dian)(dian)(dian)纜是用于傳輸電(dian)(dian)(dian)力、傳輸信(xin)息和實現(xian)(xian)電(dian)(dian)(dian)磁能量轉(zhuan)換的一大(da)類電(dian)(dian)(dian)工產品。在抽查過程(cheng)中，發現(xian)(xian)了大(da)量的不合格產品，這些劣質(zhi)產品給電(dian)(dian)(dian)力系統正常運(yun)行埋(mai)下(xia)諸多隱患。

1、標(biao)(biao)(biao)志不合格(ge)的(de)電(dian)線電(dian)纜(lan)。標(biao)(biao)(biao)志是(shi)(shi)電(dian)線電(dian)纜(lan)使(shi)用識(shi)(shi)別產品(pin)基本信息(xi)的(de)主(zhu)要途(tu)徑(jing)，根據(ju)標(biao)(biao)(biao)準(zhun)(zhun)規定標(biao)(biao)(biao)志的(de)主(zhu)要內(nei)容是(shi)(shi)：產品(pin)型(xing)號、規格(ge)、標(biao)(biao)(biao)準(zhun)(zhun)號、廠(chang)名(ming)、產地(di)等在一(yi)定的(de)標(biao)(biao)(biao)示間(jian)距內(nei)，當標(biao)(biao)(biao)志不合格(ge)時(shi)，會造成施工人(ren)員識(shi)(shi)別錯誤，嚴重(zhong)時(shi)會引發電(dian)氣事(shi)故。

2、結構尺(chi)寸不合格的電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)。結構尺(chi)寸的主(zhu)要問(wen)題是護(hu)套(tao)厚(hou)度(du)(du)，絕(jue)緣(yuan)厚(hou)度(du)(du)，當電(dian)(dian)(dian)(dian)纜(lan)的護(hu)套(tao)和(he)絕(jue)緣(yuan)厚(hou)度(du)(du)不達標(biao)時(shi)(shi)，致(zhi)使電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)耐電(dian)(dian)(dian)(dian)氣(qi)(qi)強度(du)(du)會嚴重降(jiang)低，導致(zhi)電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)的使用壽命縮短，嚴重時(shi)(shi)可導致(zhi)電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)被擊穿，絕(jue)緣(yuan)（護(hu)套(tao)）層起不到正常保護(hu)作用，從而發(fa)生電(dian)(dian)(dian)(dian)氣(qi)(qi)短路和(he)火災等現象。

3、護(hu)套式(shi)(shi)絕緣(yuan)老化前的(de)(de)抗張(zhang)強(qiang)度、伸(shen)(shen)長(chang)率(lv)合(he)格(ge)(ge)的(de)(de)電(dian)線電(dian)纜。絕緣(yuan)護(hu)套老化前的(de)(de)抗張(zhang)強(qiang)度、伸(shen)(shen)長(chang)率(lv)不(bu)合(he)格(ge)(ge)直接大(da)大(da)縮短電(dian)線電(dian)纜的(de)(de)工作(zuo)用壽命，而且(qie)在(zai)施(shi)工或在(zai)長(chang)時間(jian)通電(dian)且(qie)溫度較高的(de)(de)環(huan)境中，極易(yi)出現(xian)絕緣(yuan)體斷裂，致使帶(dai)電(dian)導(dao)體裸露，發(fa)生能觸電(dian)式(shi)(shi)短路(lu)危險。其不(bu)合(he)格(ge)(ge)的(de)(de)主要原(yuan)因是使用了再生料生產，以降低產品成(cheng)本，二是不(bu)具備生產資格(ge)(ge)小(xiao)型(xing)企(qi)業(ye)。

4、導(dao)(dao)(dao)(dao)體電(dian)(dian)(dian)阻不合(he)格的(de)(de)電(dian)(dian)(dian)線(xian)(xian)(xian)。導(dao)(dao)(dao)(dao)體電(dian)(dian)(dian)阻主要(yao)(yao)是考核電(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)纜的(de)(de)導(dao)(dao)(dao)(dao)體材(cai)(cai)料以及(ji)截面(mian)是否符合(he)的(de)(de)重(zhong)要(yao)(yao)指標。當導(dao)(dao)(dao)(dao)體電(dian)(dian)(dian)阻超(chao)標時，就(jiu)增大了(le)電(dian)(dian)(dian)流在線(xian)(xian)(xian)路上(shang)通過(guo)(guo)時的(de)(de)損耗，加劇了(le)電(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)纜的(de)(de)發(fa)熱。導(dao)(dao)(dao)(dao)體電(dian)(dian)(dian)阻不合(he)格的(de)(de)原(yuan)因，主要(yao)(yao)進企業為了(le)降低成(cheng)本(ben)，將(jiang)占(zhan)原(yuan)材(cai)(cai)料成(cheng)本(ben)80%的(de)(de)銅材(cai)(cai)縮水，要(yao)(yao)么降低導(dao)(dao)(dao)(dao)體的(de)(de)截面(mian)積，要(yao)(yao)么使用含雜質過(guo)(guo)高的(de)(de)再(zai)生銅，這樣致使電(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)纜的(de)(de)導(dao)(dao)(dao)(dao)體電(dian)(dian)(dian)阻嚴重(zhong)超(chao)標，在使用過(guo)(guo)程(cheng)中除易引發(fa)火(huo)災，還會加速包(bao)覆在電(dian)(dian)(dian)線(xian)(xian)(xian)外(wai)的(de)(de)絕緣層(ceng)的(de)(de)老化。

在購(gou)買電(dian)線電(dian)纜的過程中，消費(fei)者應注意(yi)以下(xia)幾個事

第一、要觀(guan)察(cha)電線(xian)的(de)外觀(guan)。合格(ge)產品(pin)的(de)絕(jue)緣(yuan)（護套）層(ceng)柔軟、有韌(ren)性(xing)和伸(shen)縮性(xing)、表面層(ceng)緊密、光滑、無粗糙感。如果包裹電線(xian)的(de)塑料很(hen)容易被剝去，則存在塑料強度不夠的(de)問題(ti)。

第(di)二、要看電線的截面。合格產品(pin)的銅芯或(huo)鋁(lv)芯表面應該具有金屬光澤，表面發(fa)黑的銅或(huo)表面發(fa)白的鋁(lv)說(shuo)明已被氧化。

第三、在購買(mai)電線時應注意(yi)查看質(zhi)量(liang)合格(ge)證書。如果電線的質(zhi)量(liang)合格(ge)，那么(me)其電線質(zhi)量(liang)應該(gai)也受過(guo)檢驗，不(bu)會有太大的問題。
