不合(he)格電(dian)線電(dian)纜的危害(hai)

電(dian)(dian)線電(dian)(dian)纜是用于(yu)傳(chuan)輸(shu)電(dian)(dian)力(li)、傳(chuan)輸(shu)信息和(he)實現(xian)電(dian)(dian)磁能量轉換(huan)的一大(da)類電(dian)(dian)工產(chan)品(pin)。在抽查過程中，發(fa)現(xian)了(le)大(da)量的不合格產(chan)品(pin)，這些劣(lie)質產(chan)品(pin)給電(dian)(dian)力(li)系(xi)統正(zheng)常運行埋下諸多隱患(huan)。

1、標(biao)(biao)志不(bu)合(he)格的(de)(de)電(dian)線電(dian)纜。標(biao)(biao)志是(shi)電(dian)線電(dian)纜使(shi)用識別產品基本信息的(de)(de)主(zhu)要途徑，根據標(biao)(biao)準規(gui)定標(biao)(biao)志的(de)(de)主(zhu)要內容是(shi)：產品型號、規(gui)格、標(biao)(biao)準號、廠名(ming)、產地等在一定的(de)(de)標(biao)(biao)示間距內，當標(biao)(biao)志不(bu)合(he)格時，會(hui)造成施工人(ren)員識別錯誤(wu)，嚴(yan)重時會(hui)引(yin)發電(dian)氣事故。

2、結構(gou)尺(chi)寸(cun)不(bu)合格的(de)電線(xian)電纜(lan)(lan)。結構(gou)尺(chi)寸(cun)的(de)主(zhu)要問題(ti)是護(hu)套(tao)厚度(du)，絕緣厚度(du)，當(dang)電纜(lan)(lan)的(de)護(hu)套(tao)和絕緣厚度(du)不(bu)達標時，致(zhi)使電線(xian)電纜(lan)(lan)耐電氣(qi)強度(du)會嚴重(zhong)降低，導致(zhi)電線(xian)電纜(lan)(lan)的(de)使用壽命縮短(duan)，嚴重(zhong)時可導致(zhi)電線(xian)電纜(lan)(lan)被擊穿，絕緣（護(hu)套(tao)）層起不(bu)到正常保護(hu)作用，從而發(fa)生電氣(qi)短(duan)路和火災(zai)等現(xian)象(xiang)。

3、護套式絕緣老化(hua)前的抗(kang)張(zhang)強度、伸長率合(he)格的電(dian)線電(dian)纜。絕緣護套老化(hua)前的抗(kang)張(zhang)強度、伸長率不(bu)合(he)格直接(jie)大(da)大(da)縮短電(dian)線電(dian)纜的工(gong)作用(yong)壽命，而且在施工(gong)或在長時間(jian)通電(dian)且溫度較高(gao)的環境中，極易出現絕緣體斷裂(lie)，致(zhi)使(shi)帶電(dian)導體裸(luo)露(lu)，發(fa)生(sheng)能觸(chu)電(dian)式短路危險。其不(bu)合(he)格的主要原因是(shi)使(shi)用(yong)了(le)再生(sheng)料生(sheng)產，以降低產品成本，二是(shi)不(bu)具備(bei)生(sheng)產資格小(xiao)型企業(ye)。

4、導(dao)(dao)體(ti)電(dian)阻(zu)(zu)(zu)不合(he)格(ge)的(de)電(dian)線(xian)(xian)(xian)。導(dao)(dao)體(ti)電(dian)阻(zu)(zu)(zu)主(zhu)(zhu)要(yao)是(shi)考核(he)電(dian)線(xian)(xian)(xian)電(dian)纜的(de)導(dao)(dao)體(ti)材料以及截面是(shi)否符(fu)合(he)的(de)重(zhong)要(yao)指(zhi)標(biao)(biao)。當導(dao)(dao)體(ti)電(dian)阻(zu)(zu)(zu)超標(biao)(biao)時，就增大了電(dian)流(liu)在(zai)線(xian)(xian)(xian)路(lu)上通過時的(de)損耗，加(jia)劇(ju)了電(dian)線(xian)(xian)(xian)電(dian)纜的(de)發熱(re)。導(dao)(dao)體(ti)電(dian)阻(zu)(zu)(zu)不合(he)格(ge)的(de)原因，主(zhu)(zhu)要(yao)進企(qi)業為了降(jiang)低成(cheng)(cheng)本，將(jiang)占原材料成(cheng)(cheng)本80%的(de)銅材縮水(shui)，要(yao)么(me)降(jiang)低導(dao)(dao)體(ti)的(de)截面積，要(yao)么(me)使用含雜質(zhi)過高的(de)再(zai)生(sheng)銅，這樣(yang)致(zhi)使電(dian)線(xian)(xian)(xian)電(dian)纜的(de)導(dao)(dao)體(ti)電(dian)阻(zu)(zu)(zu)嚴重(zhong)超標(biao)(biao)，在(zai)使用過程中除易引發火災，還會加(jia)速(su)包覆在(zai)電(dian)線(xian)(xian)(xian)外的(de)絕緣(yuan)層(ceng)的(de)老化。

在(zai)購買電線電纜(lan)的過程中(zhong)，消(xiao)費者應注意以下幾(ji)個事

第(di)一、要觀(guan)察電線(xian)(xian)的外觀(guan)。合(he)格產(chan)品(pin)的絕緣(yuan)（護(hu)套(tao)）層柔軟、有(you)韌性(xing)和伸縮性(xing)、表(biao)面層緊密、光(guang)滑、無粗糙感。如果包裹(guo)電線(xian)(xian)的塑料很容(rong)易被剝去，則存在塑料強度(du)不(bu)夠的問題。

第二、要看電線的截面(mian)。合格(ge)產品的銅(tong)芯(xin)或鋁芯(xin)表(biao)面(mian)應該具有(you)金屬光澤，表(biao)面(mian)發黑(hei)的銅(tong)或表(biao)面(mian)發白的鋁說明已被(bei)氧(yang)化。

第三、在(zai)購買電(dian)(dian)(dian)線時應注意查看(kan)質(zhi)(zhi)量合(he)格(ge)證書。如果電(dian)(dian)(dian)線的質(zhi)(zhi)量合(he)格(ge)，那么其電(dian)(dian)(dian)線質(zhi)(zhi)量應該(gai)也受過(guo)檢驗(yan)，不會有(you)太大的問(wen)題。
