不(bu)合格(ge)電(dian)線(xian)電(dian)纜的危害(hai)

電線電纜是用于傳輸(shu)電力、傳輸(shu)信息和實現電磁能量轉(zhuan)換的一大(da)類電工(gong)產(chan)(chan)品(pin)(pin)。在抽查過程中(zhong)，發現了大(da)量的不合格產(chan)(chan)品(pin)(pin)，這些劣(lie)質產(chan)(chan)品(pin)(pin)給(gei)電力系統正常(chang)運(yun)行埋(mai)下諸多隱患。

1、標志(zhi)不(bu)合格的電(dian)(dian)線電(dian)(dian)纜(lan)(lan)。標志(zhi)是(shi)電(dian)(dian)線電(dian)(dian)纜(lan)(lan)使用識別產(chan)品基本(ben)信(xin)息的主要途徑，根據標準(zhun)規定標志(zhi)的主要內容是(shi)：產(chan)品型號(hao)、規格、標準(zhun)號(hao)、廠名、產(chan)地等在(zai)一定的標示間距內，當標志(zhi)不(bu)合格時，會造成施工(gong)人員識別錯誤，嚴重時會引發電(dian)(dian)氣(qi)事(shi)故。

2、結(jie)構尺(chi)寸不合格的電線(xian)電纜(lan)。結(jie)構尺(chi)寸的主要問題是護(hu)(hu)套(tao)厚度(du)(du)(du)，絕(jue)(jue)緣厚度(du)(du)(du)，當電纜(lan)的護(hu)(hu)套(tao)和絕(jue)(jue)緣厚度(du)(du)(du)不達(da)標時(shi)，致(zhi)使電線(xian)電纜(lan)耐電氣(qi)強(qiang)度(du)(du)(du)會嚴(yan)重降低，導致(zhi)電線(xian)電纜(lan)的使用(yong)壽(shou)命縮短，嚴(yan)重時(shi)可導致(zhi)電線(xian)電纜(lan)被(bei)擊穿，絕(jue)(jue)緣（護(hu)(hu)套(tao)）層(ceng)起不到正常保護(hu)(hu)作用(yong)，從而發(fa)生電氣(qi)短路和火災等現象。

3、護套(tao)式絕(jue)緣老(lao)化前的(de)(de)(de)抗張強度、伸長率合(he)格(ge)的(de)(de)(de)電(dian)線電(dian)纜。絕(jue)緣護套(tao)老(lao)化前的(de)(de)(de)抗張強度、伸長率不(bu)合(he)格(ge)直接大(da)大(da)縮短電(dian)線電(dian)纜的(de)(de)(de)工(gong)作(zuo)用壽命(ming)，而且(qie)在施(shi)工(gong)或(huo)在長時間(jian)通電(dian)且(qie)溫度較高的(de)(de)(de)環境(jing)中，極易出現(xian)絕(jue)緣體斷裂，致使帶(dai)電(dian)導體裸露，發生(sheng)能觸電(dian)式短路(lu)危險。其不(bu)合(he)格(ge)的(de)(de)(de)主要原因是使用了再生(sheng)料生(sheng)產(chan)(chan)，以(yi)降低(di)產(chan)(chan)品成本，二是不(bu)具(ju)備生(sheng)產(chan)(chan)資(zi)格(ge)小型企業。

4、導(dao)(dao)(dao)體(ti)電(dian)(dian)(dian)阻(zu)不合格(ge)的(de)(de)電(dian)(dian)(dian)線。導(dao)(dao)(dao)體(ti)電(dian)(dian)(dian)阻(zu)主(zhu)要(yao)(yao)是(shi)考核電(dian)(dian)(dian)線電(dian)(dian)(dian)纜的(de)(de)導(dao)(dao)(dao)體(ti)材料(liao)以及(ji)截面(mian)是(shi)否符合的(de)(de)重要(yao)(yao)指標(biao)。當導(dao)(dao)(dao)體(ti)電(dian)(dian)(dian)阻(zu)超(chao)標(biao)時(shi)，就增大了(le)電(dian)(dian)(dian)流(liu)在線路上(shang)通過(guo)時(shi)的(de)(de)損耗，加(jia)(jia)劇了(le)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜的(de)(de)發熱(re)。導(dao)(dao)(dao)體(ti)電(dian)(dian)(dian)阻(zu)不合格(ge)的(de)(de)原因，主(zhu)要(yao)(yao)進企業為了(le)降低成本，將占原材料(liao)成本80%的(de)(de)銅(tong)材縮水，要(yao)(yao)么降低導(dao)(dao)(dao)體(ti)的(de)(de)截面(mian)積，要(yao)(yao)么使用含雜質過(guo)高(gao)的(de)(de)再生銅(tong)，這樣致使電(dian)(dian)(dian)線電(dian)(dian)(dian)纜的(de)(de)導(dao)(dao)(dao)體(ti)電(dian)(dian)(dian)阻(zu)嚴重超(chao)標(biao)，在使用過(guo)程中除(chu)易引發火災(zai)，還會(hui)加(jia)(jia)速(su)包覆(fu)在電(dian)(dian)(dian)線外的(de)(de)絕緣(yuan)層的(de)(de)老(lao)化。

在購買電線電纜(lan)的過程(cheng)中，消費者應(ying)注意以下幾個(ge)事

第一、要觀察電(dian)線的(de)(de)外觀。合格(ge)產品(pin)的(de)(de)絕(jue)緣（護套）層柔軟(ruan)、有韌(ren)性和伸縮性、表面層緊密、光滑(hua)、無粗糙感。如果包(bao)裹電(dian)線的(de)(de)塑料(liao)(liao)很容(rong)易被剝去，則(ze)存(cun)在塑料(liao)(liao)強度(du)不夠的(de)(de)問題。

第二、要看電線的截(jie)面(mian)(mian)。合格產品的銅(tong)芯或(huo)鋁芯表面(mian)(mian)應(ying)該具有(you)金屬(shu)光澤，表面(mian)(mian)發(fa)黑的銅(tong)或(huo)表面(mian)(mian)發(fa)白的鋁說明已(yi)被(bei)氧化。

第三(san)、在(zai)購買(mai)電線時應注意(yi)查看質(zhi)量合(he)格證書。如果電線的質(zhi)量合(he)格，那(nei)么其電線質(zhi)量應該也(ye)受過檢驗(yan)，不會有太大(da)的問題(ti)。
