不合格電線電纜的危害

電(dian)線電(dian)纜是用(yong)于傳輸電(dian)力(li)(li)、傳輸信息和實現電(dian)磁能量轉換的一大(da)(da)類電(dian)工產品(pin)。在抽查過程中，發現了大(da)(da)量的不合格產品(pin)，這(zhe)些(xie)劣質(zhi)產品(pin)給電(dian)力(li)(li)系統正常運(yun)行(xing)埋下(xia)諸多隱患。

1、標(biao)志不合格(ge)的電線電纜。標(biao)志是電線電纜使(shi)用識別產(chan)品基本(ben)信息的主要(yao)途徑，根據標(biao)準規定標(biao)志的主要(yao)內(nei)容(rong)是：產(chan)品型號(hao)、規格(ge)、標(biao)準號(hao)、廠(chang)名、產(chan)地(di)等(deng)在一定的標(biao)示間距內(nei)，當(dang)標(biao)志不合格(ge)時，會造成施工人員識別錯(cuo)誤(wu)，嚴重時會引(yin)發電氣事故。

2、結(jie)構尺(chi)寸不合格的電(dian)(dian)線(xian)電(dian)(dian)纜(lan)(lan)。結(jie)構尺(chi)寸的主要問(wen)題(ti)是護(hu)套(tao)厚(hou)度，絕緣厚(hou)度，當電(dian)(dian)纜(lan)(lan)的護(hu)套(tao)和絕緣厚(hou)度不達(da)標時(shi)，致(zhi)(zhi)使電(dian)(dian)線(xian)電(dian)(dian)纜(lan)(lan)耐電(dian)(dian)氣強度會嚴(yan)重降低(di)，導(dao)致(zhi)(zhi)電(dian)(dian)線(xian)電(dian)(dian)纜(lan)(lan)的使用壽命(ming)縮短(duan)，嚴(yan)重時(shi)可導(dao)致(zhi)(zhi)電(dian)(dian)線(xian)電(dian)(dian)纜(lan)(lan)被擊穿，絕緣（護(hu)套(tao)）層起不到正常保護(hu)作用，從而發生電(dian)(dian)氣短(duan)路和火災等現象。

3、護(hu)套式(shi)絕(jue)緣(yuan)老化前(qian)的(de)(de)(de)抗張強(qiang)度(du)、伸(shen)長(chang)率合(he)格的(de)(de)(de)電(dian)(dian)線電(dian)(dian)纜(lan)。絕(jue)緣(yuan)護(hu)套老化前(qian)的(de)(de)(de)抗張強(qiang)度(du)、伸(shen)長(chang)率不合(he)格直(zhi)接大(da)(da)大(da)(da)縮(suo)短電(dian)(dian)線電(dian)(dian)纜(lan)的(de)(de)(de)工(gong)作用(yong)壽(shou)命(ming)，而且在施工(gong)或在長(chang)時間通電(dian)(dian)且溫度(du)較高的(de)(de)(de)環境中，極易出現絕(jue)緣(yuan)體斷裂(lie)，致(zhi)使(shi)(shi)帶(dai)電(dian)(dian)導體裸露，發生(sheng)能觸(chu)電(dian)(dian)式(shi)短路危險。其不合(he)格的(de)(de)(de)主要原因是(shi)使(shi)(shi)用(yong)了再生(sheng)料生(sheng)產，以降(jiang)低產品成本，二是(shi)不具備生(sheng)產資格小型企業。

4、導(dao)(dao)(dao)體(ti)電(dian)(dian)(dian)阻(zu)(zu)不合格的(de)(de)(de)電(dian)(dian)(dian)線。導(dao)(dao)(dao)體(ti)電(dian)(dian)(dian)阻(zu)(zu)主要是考(kao)核電(dian)(dian)(dian)線電(dian)(dian)(dian)纜的(de)(de)(de)導(dao)(dao)(dao)體(ti)材(cai)料(liao)以及截面是否符合的(de)(de)(de)重(zhong)要指(zhi)標。當(dang)導(dao)(dao)(dao)體(ti)電(dian)(dian)(dian)阻(zu)(zu)超標時，就(jiu)增大了電(dian)(dian)(dian)流(liu)在線路上通(tong)過(guo)(guo)時的(de)(de)(de)損耗，加(jia)劇了電(dian)(dian)(dian)線電(dian)(dian)(dian)纜的(de)(de)(de)發熱。導(dao)(dao)(dao)體(ti)電(dian)(dian)(dian)阻(zu)(zu)不合格的(de)(de)(de)原因，主要進企業為(wei)了降低(di)成本，將占(zhan)原材(cai)料(liao)成本80%的(de)(de)(de)銅材(cai)縮水(shui)，要么降低(di)導(dao)(dao)(dao)體(ti)的(de)(de)(de)截面積，要么使用(yong)含雜質過(guo)(guo)高(gao)的(de)(de)(de)再生(sheng)銅，這樣(yang)致使電(dian)(dian)(dian)線電(dian)(dian)(dian)纜的(de)(de)(de)導(dao)(dao)(dao)體(ti)電(dian)(dian)(dian)阻(zu)(zu)嚴重(zhong)超標，在使用(yong)過(guo)(guo)程中除易引(yin)發火(huo)災(zai)，還(huan)會(hui)加(jia)速包(bao)覆在電(dian)(dian)(dian)線外(wai)的(de)(de)(de)絕緣層的(de)(de)(de)老化。

在購買電線電纜的過程中，消費(fei)者應(ying)注意以(yi)下幾個事(shi)

第一、要觀察電(dian)線的外觀。合格(ge)產品的絕緣（護套）層柔(rou)軟、有韌性(xing)和(he)伸縮性(xing)、表面層緊密(mi)、光滑、無粗糙感。如果(guo)包裹電(dian)線的塑(su)料很容易被剝(bo)去，則存(cun)在(zai)塑(su)料強度不(bu)夠的問題。

第二、要看電線的截面(mian)。合格產品(pin)的銅(tong)芯或(huo)鋁芯表(biao)面(mian)應該具有金屬光澤，表(biao)面(mian)發黑(hei)的銅(tong)或(huo)表(biao)面(mian)發白(bai)的鋁說明已被氧化。

第三(san)、在(zai)購買電(dian)線(xian)時(shi)應(ying)注意查看質量(liang)合(he)格(ge)證書。如果電(dian)線(xian)的質量(liang)合(he)格(ge)，那么(me)其電(dian)線(xian)質量(liang)應(ying)該也受過檢驗，不會有太大的問題。
