不合(he)格(ge)電線電纜的(de)危(wei)害(hai)

電(dian)(dian)線電(dian)(dian)纜是用于(yu)傳(chuan)輸電(dian)(dian)力(li)、傳(chuan)輸信息和實現電(dian)(dian)磁能量轉換的(de)一大(da)(da)類電(dian)(dian)工產品(pin)(pin)。在抽查過程中，發現了大(da)(da)量的(de)不(bu)合格產品(pin)(pin)，這(zhe)些劣質產品(pin)(pin)給電(dian)(dian)力(li)系統正常運行埋(mai)下諸多隱患。

1、標(biao)(biao)(biao)志不合格的(de)電(dian)線電(dian)纜。標(biao)(biao)(biao)志是電(dian)線電(dian)纜使用識別(bie)產(chan)品基本(ben)信息的(de)主(zhu)要途徑，根據(ju)標(biao)(biao)(biao)準(zhun)規(gui)定標(biao)(biao)(biao)志的(de)主(zhu)要內(nei)容是：產(chan)品型號、規(gui)格、標(biao)(biao)(biao)準(zhun)號、廠名、產(chan)地等在(zai)一(yi)定的(de)標(biao)(biao)(biao)示間(jian)距內(nei)，當標(biao)(biao)(biao)志不合格時，會(hui)造成施(shi)工人員(yuan)識別(bie)錯(cuo)誤，嚴重時會(hui)引發電(dian)氣事(shi)故。

2、結(jie)構(gou)尺(chi)寸不(bu)合(he)格的(de)電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)。結(jie)構(gou)尺(chi)寸的(de)主(zhu)要(yao)問題是護(hu)(hu)套厚(hou)度(du)，絕(jue)緣厚(hou)度(du)，當電(dian)(dian)(dian)(dian)纜(lan)的(de)護(hu)(hu)套和絕(jue)緣厚(hou)度(du)不(bu)達(da)標(biao)時(shi)，致使電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)耐(nai)電(dian)(dian)(dian)(dian)氣強度(du)會嚴(yan)(yan)重降低，導(dao)致電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)的(de)使用壽命(ming)縮短，嚴(yan)(yan)重時(shi)可(ke)導(dao)致電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)被擊穿(chuan)，絕(jue)緣（護(hu)(hu)套）層起(qi)不(bu)到正常保護(hu)(hu)作用，從(cong)而發生電(dian)(dian)(dian)(dian)氣短路和火災等現象。

3、護套式絕(jue)緣(yuan)老化前的(de)抗張強度、伸長率合格的(de)電(dian)(dian)線(xian)電(dian)(dian)纜。絕(jue)緣(yuan)護套老化前的(de)抗張強度、伸長率不(bu)(bu)合格直接大大縮短(duan)電(dian)(dian)線(xian)電(dian)(dian)纜的(de)工作用(yong)壽命，而且在施工或在長時間(jian)通電(dian)(dian)且溫度較高的(de)環境中，極易出現絕(jue)緣(yuan)體(ti)斷(duan)裂，致使帶電(dian)(dian)導體(ti)裸露，發生(sheng)能(neng)觸(chu)電(dian)(dian)式短(duan)路危險。其不(bu)(bu)合格的(de)主要原因是使用(yong)了再生(sheng)料生(sheng)產，以降低產品(pin)成本，二是不(bu)(bu)具備生(sheng)產資格小型企業。

4、導(dao)(dao)(dao)體(ti)電(dian)(dian)阻(zu)(zu)不(bu)合(he)格(ge)的(de)(de)電(dian)(dian)線(xian)。導(dao)(dao)(dao)體(ti)電(dian)(dian)阻(zu)(zu)主要(yao)是(shi)考核電(dian)(dian)線(xian)電(dian)(dian)纜的(de)(de)導(dao)(dao)(dao)體(ti)材料以及截面(mian)(mian)是(shi)否符合(he)的(de)(de)重要(yao)指標。當導(dao)(dao)(dao)體(ti)電(dian)(dian)阻(zu)(zu)超標時，就增大了(le)電(dian)(dian)流在(zai)線(xian)路上通過(guo)時的(de)(de)損耗(hao)，加劇了(le)電(dian)(dian)線(xian)電(dian)(dian)纜的(de)(de)發熱。導(dao)(dao)(dao)體(ti)電(dian)(dian)阻(zu)(zu)不(bu)合(he)格(ge)的(de)(de)原因，主要(yao)進企業為了(le)降低成本，將占原材料成本80%的(de)(de)銅材縮水，要(yao)么降低導(dao)(dao)(dao)體(ti)的(de)(de)截面(mian)(mian)積(ji)，要(yao)么使用(yong)含雜(za)質過(guo)高的(de)(de)再(zai)生銅，這樣致使電(dian)(dian)線(xian)電(dian)(dian)纜的(de)(de)導(dao)(dao)(dao)體(ti)電(dian)(dian)阻(zu)(zu)嚴重超標，在(zai)使用(yong)過(guo)程中除易引(yin)發火災，還會加速包覆在(zai)電(dian)(dian)線(xian)外的(de)(de)絕(jue)緣層的(de)(de)老化。

在(zai)購買電(dian)(dian)線電(dian)(dian)纜的過程中，消費者應注意以下幾(ji)個事

第一(yi)、要觀察電(dian)線(xian)的(de)外觀。合格產品的(de)絕(jue)緣（護套(tao)）層(ceng)柔(rou)軟、有韌性和伸(shen)縮性、表面層(ceng)緊密、光滑、無粗糙感。如果包裹電(dian)線(xian)的(de)塑(su)料很容易被剝去，則存在塑(su)料強度不夠(gou)的(de)問題。

第二(er)、要看電(dian)線的截面(mian)。合格(ge)產品的銅(tong)芯或鋁(lv)芯表面(mian)應該(gai)具(ju)有金屬(shu)光(guang)澤，表面(mian)發黑(hei)的銅(tong)或表面(mian)發白的鋁(lv)說明已被氧化。

第(di)三、在購(gou)買電線(xian)時應(ying)注意查看質量(liang)(liang)合格證(zheng)書(shu)。如果電線(xian)的質量(liang)(liang)合格，那么其電線(xian)質量(liang)(liang)應(ying)該也受過檢驗，不會(hui)有太大的問題。
