不合(he)格(ge)電線電纜的危害(hai)

電線(xian)電纜是用于傳輸電力、傳輸信(xin)息和(he)實(shi)現電磁能量轉換的一大類電工產品。在抽查過(guo)程中，發(fa)現了大量的不合(he)格產品，這些劣質產品給電力系(xi)統正常運行埋下諸多(duo)隱患。

1、標(biao)(biao)志(zhi)不合(he)格的電(dian)線電(dian)纜。標(biao)(biao)志(zhi)是(shi)電(dian)線電(dian)纜使用識(shi)別產品(pin)(pin)基本信(xin)息的主要途徑，根(gen)據標(biao)(biao)準規定標(biao)(biao)志(zhi)的主要內容是(shi)：產品(pin)(pin)型號、規格、標(biao)(biao)準號、廠(chang)名、產地等在一定的標(biao)(biao)示間距內，當標(biao)(biao)志(zhi)不合(he)格時(shi)，會造(zao)成施工人員(yuan)識(shi)別錯誤，嚴重時(shi)會引發電(dian)氣事故。

2、結(jie)(jie)構(gou)尺(chi)寸不(bu)合格的電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)。結(jie)(jie)構(gou)尺(chi)寸的主要問題是護套厚度(du)，絕緣厚度(du)，當電(dian)(dian)(dian)纜(lan)的護套和絕緣厚度(du)不(bu)達標時，致(zhi)使電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)耐電(dian)(dian)(dian)氣強度(du)會嚴重降低，導致(zhi)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)的使用(yong)壽(shou)命(ming)縮(suo)短，嚴重時可導致(zhi)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)被擊穿，絕緣（護套）層起不(bu)到正常保護作(zuo)用(yong)，從而發生電(dian)(dian)(dian)氣短路和火災等(deng)現象。

3、護套(tao)式(shi)絕(jue)緣老(lao)化前的(de)抗張(zhang)強(qiang)度(du)(du)、伸長(chang)(chang)率合(he)格(ge)的(de)電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)。絕(jue)緣護套(tao)老(lao)化前的(de)抗張(zhang)強(qiang)度(du)(du)、伸長(chang)(chang)率不合(he)格(ge)直接大(da)大(da)縮短(duan)電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)的(de)工(gong)作用(yong)壽命，而且(qie)在施工(gong)或在長(chang)(chang)時間(jian)通電(dian)(dian)(dian)(dian)且(qie)溫度(du)(du)較高的(de)環境(jing)中，極易出現(xian)絕(jue)緣體(ti)斷(duan)裂(lie)，致使帶電(dian)(dian)(dian)(dian)導體(ti)裸露，發(fa)生(sheng)能觸電(dian)(dian)(dian)(dian)式(shi)短(duan)路危(wei)險。其不合(he)格(ge)的(de)主要原因是(shi)使用(yong)了再生(sheng)料(liao)生(sheng)產(chan)，以降(jiang)低產(chan)品成本，二是(shi)不具備生(sheng)產(chan)資格(ge)小(xiao)型企(qi)業。

4、導(dao)體(ti)電(dian)(dian)(dian)(dian)阻(zu)(zu)不(bu)合(he)格的(de)(de)電(dian)(dian)(dian)(dian)線。導(dao)體(ti)電(dian)(dian)(dian)(dian)阻(zu)(zu)主要(yao)是考(kao)核電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)的(de)(de)導(dao)體(ti)材(cai)料以及截(jie)面是否符合(he)的(de)(de)重要(yao)指標。當導(dao)體(ti)電(dian)(dian)(dian)(dian)阻(zu)(zu)超(chao)標時，就增大了電(dian)(dian)(dian)(dian)流(liu)在線路上(shang)通過(guo)時的(de)(de)損耗(hao)，加(jia)(jia)劇了電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)的(de)(de)發熱。導(dao)體(ti)電(dian)(dian)(dian)(dian)阻(zu)(zu)不(bu)合(he)格的(de)(de)原因，主要(yao)進企業為(wei)了降低成本(ben)，將占原材(cai)料成本(ben)80%的(de)(de)銅(tong)(tong)材(cai)縮水(shui)，要(yao)么(me)降低導(dao)體(ti)的(de)(de)截(jie)面積(ji)，要(yao)么(me)使(shi)用(yong)含雜(za)質過(guo)高的(de)(de)再生銅(tong)(tong)，這樣致使(shi)電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)的(de)(de)導(dao)體(ti)電(dian)(dian)(dian)(dian)阻(zu)(zu)嚴重超(chao)標，在使(shi)用(yong)過(guo)程中(zhong)除易引發火災，還(huan)會加(jia)(jia)速(su)包覆(fu)在電(dian)(dian)(dian)(dian)線外(wai)的(de)(de)絕緣(yuan)層的(de)(de)老(lao)化。

在購買電(dian)線電(dian)纜的過程中，消費者應注(zhu)意以下幾個(ge)事

第一、要觀察電線的(de)外(wai)觀。合格產(chan)品的(de)絕緣（護(hu)套(tao)）層柔軟、有韌性和伸縮性、表面層緊(jin)密、光滑、無粗糙(cao)感。如果包(bao)裹電線的(de)塑料很容易被(bei)剝去，則存在塑料強(qiang)度不(bu)夠(gou)的(de)問(wen)題。

第(di)二、要看電線的(de)(de)截面。合格產品的(de)(de)銅(tong)芯(xin)或鋁芯(xin)表(biao)面應該具有金屬光澤(ze)，表(biao)面發黑的(de)(de)銅(tong)或表(biao)面發白的(de)(de)鋁說明已被氧化。

第(di)三、在購(gou)買電(dian)線時應注意查(cha)看(kan)質(zhi)量合格證(zheng)書。如果電(dian)線的質(zhi)量合格，那(nei)么其(qi)電(dian)線質(zhi)量應該也受過(guo)檢驗，不會有太大的問題。
