不合(he)格電(dian)(dian)線電(dian)(dian)纜的(de)危害(hai)

電線電纜(lan)是用于傳輸(shu)(shu)電力、傳輸(shu)(shu)信息和實(shi)現電磁(ci)能量(liang)轉換的一(yi)大類電工產品(pin)(pin)。在抽查過程中，發現了大量(liang)的不合格產品(pin)(pin)，這(zhe)些(xie)劣質產品(pin)(pin)給(gei)電力系統正(zheng)常運(yun)行埋下諸多(duo)隱患(huan)。

1、標(biao)志不合格的(de)電(dian)(dian)線(xian)電(dian)(dian)纜。標(biao)志是(shi)電(dian)(dian)線(xian)電(dian)(dian)纜使用識(shi)別產(chan)品基本(ben)信息的(de)主要途徑，根據標(biao)準規定標(biao)志的(de)主要內容是(shi)：產(chan)品型(xing)號(hao)、規格、標(biao)準號(hao)、廠名、產(chan)地等在一定的(de)標(biao)示間距內，當標(biao)志不合格時，會造成施工人員識(shi)別錯誤，嚴重時會引發電(dian)(dian)氣事故。

2、結(jie)構尺寸不(bu)(bu)合格(ge)的電(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)纜(lan)。結(jie)構尺寸的主(zhu)要問(wen)題是(shi)護(hu)套(tao)(tao)厚(hou)(hou)(hou)度(du)，絕(jue)緣(yuan)(yuan)厚(hou)(hou)(hou)度(du)，當電(dian)(dian)(dian)(dian)(dian)纜(lan)的護(hu)套(tao)(tao)和絕(jue)緣(yuan)(yuan)厚(hou)(hou)(hou)度(du)不(bu)(bu)達標時，致使電(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)纜(lan)耐電(dian)(dian)(dian)(dian)(dian)氣強(qiang)度(du)會嚴重降(jiang)低，導(dao)致電(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)纜(lan)的使用壽命縮短，嚴重時可導(dao)致電(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)纜(lan)被擊穿，絕(jue)緣(yuan)(yuan)（護(hu)套(tao)(tao)）層(ceng)起不(bu)(bu)到正常保護(hu)作用，從而發生電(dian)(dian)(dian)(dian)(dian)氣短路(lu)和火(huo)災等(deng)現象。

3、護套式絕(jue)緣老(lao)化前(qian)的(de)抗張強度(du)、伸長率合(he)格的(de)電線電纜。絕(jue)緣護套老(lao)化前(qian)的(de)抗張強度(du)、伸長率不(bu)合(he)格直接(jie)大大縮短電線電纜的(de)工作用壽(shou)命，而且在(zai)施工或在(zai)長時間通電且溫(wen)度(du)較(jiao)高的(de)環境(jing)中(zhong)，極易(yi)出現絕(jue)緣體斷裂，致使(shi)帶電導體裸(luo)露，發生(sheng)能(neng)觸電式短路危險。其不(bu)合(he)格的(de)主要(yao)原因是使(shi)用了(le)再生(sheng)料生(sheng)產，以(yi)降(jiang)低(di)產品成本，二是不(bu)具備生(sheng)產資格小型企業。

4、導(dao)體(ti)(ti)(ti)(ti)電(dian)(dian)阻(zu)(zu)不合(he)格的(de)(de)(de)電(dian)(dian)線(xian)。導(dao)體(ti)(ti)(ti)(ti)電(dian)(dian)阻(zu)(zu)主(zhu)要是考核電(dian)(dian)線(xian)電(dian)(dian)纜(lan)的(de)(de)(de)導(dao)體(ti)(ti)(ti)(ti)材(cai)料以及截面是否(fou)符(fu)合(he)的(de)(de)(de)重(zhong)要指標(biao)。當(dang)導(dao)體(ti)(ti)(ti)(ti)電(dian)(dian)阻(zu)(zu)超標(biao)時，就增大(da)了電(dian)(dian)流在線(xian)路(lu)上通過(guo)(guo)時的(de)(de)(de)損耗(hao)，加(jia)劇了電(dian)(dian)線(xian)電(dian)(dian)纜(lan)的(de)(de)(de)發(fa)熱。導(dao)體(ti)(ti)(ti)(ti)電(dian)(dian)阻(zu)(zu)不合(he)格的(de)(de)(de)原因，主(zhu)要進(jin)企業為(wei)了降低成(cheng)本，將占(zhan)原材(cai)料成(cheng)本80%的(de)(de)(de)銅材(cai)縮(suo)水，要么降低導(dao)體(ti)(ti)(ti)(ti)的(de)(de)(de)截面積，要么使用(yong)含雜質(zhi)過(guo)(guo)高的(de)(de)(de)再生銅，這(zhe)樣致(zhi)使電(dian)(dian)線(xian)電(dian)(dian)纜(lan)的(de)(de)(de)導(dao)體(ti)(ti)(ti)(ti)電(dian)(dian)阻(zu)(zu)嚴重(zhong)超標(biao)，在使用(yong)過(guo)(guo)程中除(chu)易引發(fa)火(huo)災，還(huan)會加(jia)速包(bao)覆在電(dian)(dian)線(xian)外的(de)(de)(de)絕緣層的(de)(de)(de)老化。

在購買電線電纜(lan)的過程中，消費者應注(zhu)意以下幾個事

第一(yi)、要觀(guan)察電(dian)線的(de)(de)外觀(guan)。合(he)格產品的(de)(de)絕(jue)緣（護套）層(ceng)柔軟(ruan)、有(you)韌性(xing)(xing)和伸(shen)縮性(xing)(xing)、表面層(ceng)緊密(mi)、光滑、無粗糙感。如果包裹電(dian)線的(de)(de)塑料很容易被剝去(qu)，則存在塑料強度不夠的(de)(de)問題。

第二(er)、要看電線(xian)的(de)截面(mian)。合格產品的(de)銅(tong)芯(xin)或鋁芯(xin)表(biao)面(mian)應該具有金屬(shu)光澤，表(biao)面(mian)發(fa)黑的(de)銅(tong)或表(biao)面(mian)發(fa)白(bai)的(de)鋁說明已(yi)被氧(yang)化。

第(di)三(san)、在購買電線時應注意(yi)查看(kan)質(zhi)(zhi)量合(he)格(ge)證書。如果電線的質(zhi)(zhi)量合(he)格(ge)，那么(me)其電線質(zhi)(zhi)量應該也受過檢(jian)驗，不會有太(tai)大的問題。
