不合(he)格(ge)電(dian)線電(dian)纜的危(wei)害(hai)

電(dian)線電(dian)纜是用(yong)于傳輸電(dian)力、傳輸信息和實(shi)現電(dian)磁(ci)能量(liang)轉換的(de)一大(da)類電(dian)工產(chan)(chan)品。在抽查過(guo)程(cheng)中，發現了大(da)量(liang)的(de)不合格產(chan)(chan)品，這(zhe)些(xie)劣質產(chan)(chan)品給(gei)電(dian)力系統正(zheng)常運行埋下諸多(duo)隱患。

1、標(biao)(biao)志(zhi)不(bu)合格(ge)的(de)電線電纜。標(biao)(biao)志(zhi)是電線電纜使用識(shi)別(bie)產品基本(ben)信息的(de)主(zhu)要(yao)途徑(jing)，根據標(biao)(biao)準規定標(biao)(biao)志(zhi)的(de)主(zhu)要(yao)內容(rong)是：產品型號、規格(ge)、標(biao)(biao)準號、廠名、產地等在一定的(de)標(biao)(biao)示間距內，當(dang)標(biao)(biao)志(zhi)不(bu)合格(ge)時(shi)，會造成施(shi)工(gong)人員識(shi)別(bie)錯誤，嚴重時(shi)會引(yin)發電氣事故。

2、結構(gou)尺寸(cun)不(bu)合格(ge)的(de)電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)纜。結構(gou)尺寸(cun)的(de)主要問題是護套厚度，絕緣(yuan)厚度，當電(dian)(dian)(dian)(dian)(dian)纜的(de)護套和(he)絕緣(yuan)厚度不(bu)達標時(shi)(shi)，致使電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)纜耐電(dian)(dian)(dian)(dian)(dian)氣強(qiang)度會嚴重降低(di)，導致電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)纜的(de)使用壽命縮短，嚴重時(shi)(shi)可導致電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)纜被(bei)擊穿，絕緣(yuan)（護套）層起不(bu)到正(zheng)常保(bao)護作用，從而發生電(dian)(dian)(dian)(dian)(dian)氣短路和(he)火災等(deng)現象。

3、護套式(shi)絕緣老(lao)化(hua)前(qian)的(de)抗張強度(du)、伸長(chang)(chang)率(lv)合(he)格的(de)電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜。絕緣護套老(lao)化(hua)前(qian)的(de)抗張強度(du)、伸長(chang)(chang)率(lv)不合(he)格直接大(da)大(da)縮短(duan)電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜的(de)工(gong)作用壽(shou)命，而且在施工(gong)或在長(chang)(chang)時(shi)間通(tong)電(dian)(dian)(dian)(dian)且溫度(du)較高的(de)環境中(zhong)，極易出(chu)現(xian)絕緣體斷(duan)裂，致使帶電(dian)(dian)(dian)(dian)導(dao)體裸(luo)露，發生能觸(chu)電(dian)(dian)(dian)(dian)式(shi)短(duan)路危險。其不合(he)格的(de)主要原因是使用了再生料生產(chan)，以降低產(chan)品(pin)成本，二是不具備生產(chan)資(zi)格小型企業。

4、導體(ti)電(dian)(dian)(dian)阻不(bu)合格(ge)的(de)(de)(de)(de)電(dian)(dian)(dian)線(xian)。導體(ti)電(dian)(dian)(dian)阻主(zhu)要(yao)(yao)是(shi)考(kao)核電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)的(de)(de)(de)(de)導體(ti)材料(liao)以及(ji)截面(mian)是(shi)否(fou)符(fu)合的(de)(de)(de)(de)重(zhong)要(yao)(yao)指標。當導體(ti)電(dian)(dian)(dian)阻超(chao)標時，就(jiu)增大(da)了電(dian)(dian)(dian)流在線(xian)路上通過(guo)時的(de)(de)(de)(de)損(sun)耗，加劇了電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)的(de)(de)(de)(de)發熱。導體(ti)電(dian)(dian)(dian)阻不(bu)合格(ge)的(de)(de)(de)(de)原因(yin)，主(zhu)要(yao)(yao)進企業為了降低成(cheng)本，將占(zhan)原材料(liao)成(cheng)本80%的(de)(de)(de)(de)銅材縮(suo)水(shui)，要(yao)(yao)么(me)降低導體(ti)的(de)(de)(de)(de)截面(mian)積，要(yao)(yao)么(me)使(shi)用含雜(za)質過(guo)高(gao)的(de)(de)(de)(de)再生(sheng)銅，這樣致使(shi)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)的(de)(de)(de)(de)導體(ti)電(dian)(dian)(dian)阻嚴重(zhong)超(chao)標，在使(shi)用過(guo)程中除易引發火(huo)災，還會(hui)加速包(bao)覆(fu)在電(dian)(dian)(dian)線(xian)外的(de)(de)(de)(de)絕緣層的(de)(de)(de)(de)老(lao)化。

在購買電(dian)線電(dian)纜(lan)的過程(cheng)中，消費者應注意以下幾個事

第一、要(yao)觀察(cha)電(dian)線的外觀。合格產(chan)品的絕(jue)緣（護(hu)套）層(ceng)柔(rou)軟、有韌性和伸(shen)縮性、表面層(ceng)緊密、光滑、無粗糙感(gan)。如果包裹(guo)電(dian)線的塑料(liao)很容易被(bei)剝去，則存在塑料(liao)強(qiang)度不(bu)夠的問題(ti)。

第二、要看電線的(de)截(jie)面。合格產品的(de)銅芯或鋁芯表(biao)面應該(gai)具(ju)有金屬(shu)光澤(ze)，表(biao)面發(fa)黑的(de)銅或表(biao)面發(fa)白(bai)的(de)鋁說明已被氧化。

第三、在購買電(dian)線時應(ying)注意查看(kan)質量(liang)合格證書。如果電(dian)線的質量(liang)合格，那么其電(dian)線質量(liang)應(ying)該(gai)也(ye)受過檢驗，不會有(you)太大(da)的問(wen)題。
