不合(he)格(ge)電(dian)線電(dian)纜(lan)的危害

電(dian)線電(dian)纜是用于(yu)傳輸(shu)電(dian)力、傳輸(shu)信息和實現電(dian)磁能量轉(zhuan)換的一大(da)類電(dian)工產品(pin)。在抽查過程中(zhong)，發現了大(da)量的不合(he)格產品(pin)，這些劣質產品(pin)給電(dian)力系統正常運行埋下諸(zhu)多隱(yin)患。

1、標(biao)(biao)志不合(he)格的(de)電(dian)(dian)線(xian)電(dian)(dian)纜。標(biao)(biao)志是電(dian)(dian)線(xian)電(dian)(dian)纜使用識別產(chan)(chan)品基本信息的(de)主要途徑(jing)，根(gen)據標(biao)(biao)準規定標(biao)(biao)志的(de)主要內容是：產(chan)(chan)品型號、規格、標(biao)(biao)準號、廠(chang)名、產(chan)(chan)地等在(zai)一定的(de)標(biao)(biao)示間(jian)距內，當標(biao)(biao)志不合(he)格時(shi)(shi)，會造成(cheng)施工人員識別錯誤(wu)，嚴(yan)重時(shi)(shi)會引發電(dian)(dian)氣(qi)事故。

2、結(jie)構尺(chi)(chi)寸(cun)不(bu)合(he)格的(de)電(dian)線(xian)電(dian)纜(lan)(lan)。結(jie)構尺(chi)(chi)寸(cun)的(de)主要問題是(shi)護套厚度(du)，絕(jue)緣厚度(du)，當電(dian)纜(lan)(lan)的(de)護套和絕(jue)緣厚度(du)不(bu)達標時(shi)，致使電(dian)線(xian)電(dian)纜(lan)(lan)耐電(dian)氣強度(du)會嚴重(zhong)降低，導致電(dian)線(xian)電(dian)纜(lan)(lan)的(de)使用壽命縮短，嚴重(zhong)時(shi)可導致電(dian)線(xian)電(dian)纜(lan)(lan)被擊穿，絕(jue)緣（護套）層起(qi)不(bu)到(dao)正常(chang)保護作用，從而(er)發生電(dian)氣短路和火災等(deng)現象。

3、護(hu)套式絕緣老化前的(de)(de)抗張(zhang)強(qiang)度(du)、伸長率合(he)格(ge)(ge)(ge)的(de)(de)電(dian)線電(dian)纜(lan)。絕緣護(hu)套老化前的(de)(de)抗張(zhang)強(qiang)度(du)、伸長率不合(he)格(ge)(ge)(ge)直接大(da)大(da)縮短電(dian)線電(dian)纜(lan)的(de)(de)工(gong)作用(yong)壽命(ming)，而且在施工(gong)或(huo)在長時間(jian)通電(dian)且溫度(du)較高的(de)(de)環境中，極易(yi)出現絕緣體斷裂(lie)，致使帶電(dian)導(dao)體裸露，發生(sheng)(sheng)(sheng)能觸電(dian)式短路危險。其不合(he)格(ge)(ge)(ge)的(de)(de)主要原因(yin)是使用(yong)了再生(sheng)(sheng)(sheng)料生(sheng)(sheng)(sheng)產，以降低產品成本，二是不具備生(sheng)(sheng)(sheng)產資格(ge)(ge)(ge)小(xiao)型企業。

4、導(dao)體(ti)(ti)(ti)電(dian)(dian)(dian)阻(zu)不(bu)合(he)格(ge)的(de)(de)電(dian)(dian)(dian)線(xian)(xian)(xian)。導(dao)體(ti)(ti)(ti)電(dian)(dian)(dian)阻(zu)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)體(ti)(ti)(ti)材(cai)料(liao)(liao)以及截面是否符合(he)的(de)(de)重(zhong)要(yao)(yao)指標(biao)(biao)。當導(dao)體(ti)(ti)(ti)電(dian)(dian)(dian)阻(zu)超標(biao)(biao)時(shi)，就增(zeng)大(da)了(le)(le)電(dian)(dian)(dian)流在線(xian)(xian)(xian)路上通過(guo)時(shi)的(de)(de)損耗，加劇了(le)(le)電(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)纜的(de)(de)發熱。導(dao)體(ti)(ti)(ti)電(dian)(dian)(dian)阻(zu)不(bu)合(he)格(ge)的(de)(de)原因，主要(yao)(yao)進企業為了(le)(le)降(jiang)低(di)(di)成本(ben)，將占原材(cai)料(liao)(liao)成本(ben)80%的(de)(de)銅材(cai)縮水，要(yao)(yao)么(me)降(jiang)低(di)(di)導(dao)體(ti)(ti)(ti)的(de)(de)截面積，要(yao)(yao)么(me)使用含雜質過(guo)高的(de)(de)再(zai)生(sheng)銅，這樣致使電(dian)(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)(dian)纜的(de)(de)導(dao)體(ti)(ti)(ti)電(dian)(dian)(dian)阻(zu)嚴重(zhong)超標(biao)(biao)，在使用過(guo)程中除易(yi)引(yin)發火災，還(huan)會加速包覆在電(dian)(dian)(dian)線(xian)(xian)(xian)外的(de)(de)絕(jue)緣層(ceng)的(de)(de)老化。

在購(gou)買電線(xian)電纜的過程中，消(xiao)費者應注意(yi)以下幾個事

第一(yi)、要觀(guan)察電(dian)線(xian)的(de)外(wai)觀(guan)。合格產品的(de)絕緣（護(hu)套）層柔(rou)軟(ruan)、有韌性和伸縮性、表面層緊密、光(guang)滑、無(wu)粗糙感。如(ru)果包裹電(dian)線(xian)的(de)塑料很容(rong)易被剝去，則存在塑料強(qiang)度不夠的(de)問(wen)題。

第二、要看(kan)電線的(de)(de)(de)截面(mian)(mian)。合格(ge)產品(pin)的(de)(de)(de)銅芯(xin)或鋁芯(xin)表(biao)面(mian)(mian)應該(gai)具有(you)金(jin)屬光澤，表(biao)面(mian)(mian)發(fa)黑(hei)的(de)(de)(de)銅或表(biao)面(mian)(mian)發(fa)白的(de)(de)(de)鋁說明已被(bei)氧化。

第三、在(zai)購買電線時應(ying)(ying)注意(yi)查看質(zhi)量(liang)(liang)合(he)格證(zheng)書。如果電線的質(zhi)量(liang)(liang)合(he)格，那么(me)其電線質(zhi)量(liang)(liang)應(ying)(ying)該也(ye)受過檢驗，不會(hui)有太大的問題。
