不合(he)格電(dian)(dian)線電(dian)(dian)纜的(de)危害

電(dian)(dian)線(xian)電(dian)(dian)纜(lan)是用于(yu)傳輸電(dian)(dian)力、傳輸信息和(he)實現電(dian)(dian)磁(ci)能(neng)量(liang)轉(zhuan)換的(de)一(yi)大類電(dian)(dian)工產品(pin)。在(zai)抽查(cha)過程中(zhong)，發現了大量(liang)的(de)不合格產品(pin)，這些劣質(zhi)產品(pin)給電(dian)(dian)力系統(tong)正常運行埋下諸多隱患。

1、標(biao)(biao)志不(bu)(bu)合(he)格的電線電纜。標(biao)(biao)志是電線電纜使用識(shi)別產品基本(ben)信息的主(zhu)要(yao)途徑，根據標(biao)(biao)準(zhun)規(gui)定(ding)標(biao)(biao)志的主(zhu)要(yao)內(nei)容是：產品型號(hao)、規(gui)格、標(biao)(biao)準(zhun)號(hao)、廠名、產地等在(zai)一定(ding)的標(biao)(biao)示間(jian)距內(nei)，當標(biao)(biao)志不(bu)(bu)合(he)格時(shi)，會造成施工人員識(shi)別錯誤(wu)，嚴重時(shi)會引發電氣事故。

2、結(jie)構(gou)尺寸(cun)不合格(ge)的電(dian)(dian)線電(dian)(dian)纜(lan)(lan)。結(jie)構(gou)尺寸(cun)的主要問題是(shi)護套(tao)厚(hou)度(du)(du)，絕緣厚(hou)度(du)(du)，當電(dian)(dian)纜(lan)(lan)的護套(tao)和絕緣厚(hou)度(du)(du)不達標時，致使(shi)電(dian)(dian)線電(dian)(dian)纜(lan)(lan)耐(nai)電(dian)(dian)氣(qi)強(qiang)度(du)(du)會(hui)嚴重(zhong)降低，導致電(dian)(dian)線電(dian)(dian)纜(lan)(lan)的使(shi)用(yong)(yong)壽命縮短(duan)，嚴重(zhong)時可導致電(dian)(dian)線電(dian)(dian)纜(lan)(lan)被擊穿，絕緣（護套(tao)）層起不到正常保護作用(yong)(yong)，從而發生(sheng)電(dian)(dian)氣(qi)短(duan)路(lu)和火災等現象(xiang)。

3、護套(tao)式絕緣(yuan)老(lao)化前的(de)抗張(zhang)強度(du)、伸長(chang)率合格的(de)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜。絕緣(yuan)護套(tao)老(lao)化前的(de)抗張(zhang)強度(du)、伸長(chang)率不合格直接大大縮短(duan)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜的(de)工作用壽命，而(er)且在(zai)施(shi)工或在(zai)長(chang)時間(jian)通電(dian)(dian)(dian)且溫度(du)較高的(de)環境(jing)中，極(ji)易出(chu)現絕緣(yuan)體(ti)斷裂，致使(shi)帶電(dian)(dian)(dian)導(dao)體(ti)裸(luo)露，發生(sheng)能觸電(dian)(dian)(dian)式短(duan)路危險。其不合格的(de)主要原因(yin)是(shi)使(shi)用了再生(sheng)料生(sheng)產，以(yi)降低產品成(cheng)本(ben)，二(er)是(shi)不具備(bei)生(sheng)產資(zi)格小型(xing)企業(ye)。

4、導體(ti)(ti)(ti)電(dian)阻(zu)(zu)不合(he)格(ge)的電(dian)線(xian)(xian)。導體(ti)(ti)(ti)電(dian)阻(zu)(zu)主(zhu)要是考(kao)核(he)電(dian)線(xian)(xian)電(dian)纜的導體(ti)(ti)(ti)材料以及截面是否符合(he)的重(zhong)要指標。當導體(ti)(ti)(ti)電(dian)阻(zu)(zu)超(chao)標時，就增大了(le)電(dian)流在線(xian)(xian)路上通(tong)過時的損耗，加(jia)劇了(le)電(dian)線(xian)(xian)電(dian)纜的發熱。導體(ti)(ti)(ti)電(dian)阻(zu)(zu)不合(he)格(ge)的原因，主(zhu)要進企業為了(le)降低成本，將占原材料成本80%的銅(tong)材縮水(shui)，要么降低導體(ti)(ti)(ti)的截面積，要么使用(yong)含雜質過高的再(zai)生(sheng)銅(tong)，這樣(yang)致使電(dian)線(xian)(xian)電(dian)纜的導體(ti)(ti)(ti)電(dian)阻(zu)(zu)嚴重(zhong)超(chao)標，在使用(yong)過程中(zhong)除易引發火災，還(huan)會(hui)加(jia)速包覆在電(dian)線(xian)(xian)外的絕緣層的老(lao)化(hua)。

在購買電線電纜(lan)的過程中，消費者(zhe)應注意(yi)以下(xia)幾個事

第(di)一(yi)、要觀(guan)察(cha)電(dian)線(xian)的(de)外觀(guan)。合格產品(pin)的(de)絕(jue)緣（護套）層柔軟、有(you)韌性(xing)和伸縮性(xing)、表面(mian)層緊密、光滑、無(wu)粗糙感。如果包裹電(dian)線(xian)的(de)塑(su)料很(hen)容易被剝去，則存在塑(su)料強度不夠的(de)問題(ti)。

第二、要(yao)看電線(xian)的截面(mian)。合(he)格產品的銅(tong)芯或(huo)鋁芯表面(mian)應該(gai)具有金屬光澤(ze)，表面(mian)發(fa)(fa)黑的銅(tong)或(huo)表面(mian)發(fa)(fa)白的鋁說(shuo)明已被氧(yang)化(hua)。

第三、在購買電線時應(ying)注意查看質量(liang)合格(ge)證書。如(ru)果電線的(de)質量(liang)合格(ge)，那(nei)么其(qi)電線質量(liang)應(ying)該也受過檢驗(yan)，不會(hui)有太大的(de)問題。
