不合格電線(xian)電纜的(de)危害(hai)

電(dian)(dian)線電(dian)(dian)纜是用于傳輸電(dian)(dian)力、傳輸信息和(he)實現電(dian)(dian)磁能量(liang)轉換的一(yi)大類電(dian)(dian)工(gong)產品(pin)。在抽(chou)查過(guo)程中，發現了大量(liang)的不合格(ge)產品(pin)，這些劣質產品(pin)給電(dian)(dian)力系統正常運(yun)行(xing)埋下(xia)諸多隱(yin)患。

1、標志不(bu)(bu)合格的(de)(de)電(dian)(dian)線電(dian)(dian)纜(lan)。標志是電(dian)(dian)線電(dian)(dian)纜(lan)使用識別產品基本信息的(de)(de)主要途(tu)徑，根據標準規定(ding)標志的(de)(de)主要內(nei)容是：產品型號、規格、標準號、廠名、產地等在(zai)一定(ding)的(de)(de)標示間距內(nei)，當標志不(bu)(bu)合格時(shi)，會造成施工人員(yuan)識別錯(cuo)誤，嚴重時(shi)會引(yin)發電(dian)(dian)氣事(shi)故。

2、結構尺(chi)寸不(bu)合格的(de)電(dian)線電(dian)纜。結構尺(chi)寸的(de)主要問題(ti)是護(hu)套厚(hou)(hou)(hou)度，絕緣厚(hou)(hou)(hou)度，當電(dian)纜的(de)護(hu)套和絕緣厚(hou)(hou)(hou)度不(bu)達標時(shi)，致使電(dian)線電(dian)纜耐電(dian)氣強度會嚴重降低，導致電(dian)線電(dian)纜的(de)使用壽命縮(suo)短(duan)，嚴重時(shi)可導致電(dian)線電(dian)纜被擊穿，絕緣（護(hu)套）層起不(bu)到正常保(bao)護(hu)作用，從而發生電(dian)氣短(duan)路和火災等現象。

3、護(hu)套式(shi)絕(jue)緣老化(hua)前的(de)(de)(de)(de)(de)抗張(zhang)強度(du)、伸長率(lv)合(he)格(ge)的(de)(de)(de)(de)(de)電(dian)線電(dian)纜(lan)。絕(jue)緣護(hu)套老化(hua)前的(de)(de)(de)(de)(de)抗張(zhang)強度(du)、伸長率(lv)不(bu)合(he)格(ge)直接(jie)大大縮(suo)短(duan)電(dian)線電(dian)纜(lan)的(de)(de)(de)(de)(de)工作用壽(shou)命，而且在施工或在長時間通電(dian)且溫(wen)度(du)較高的(de)(de)(de)(de)(de)環境中，極易出現絕(jue)緣體斷裂，致使(shi)帶電(dian)導體裸露，發生能觸電(dian)式(shi)短(duan)路危(wei)險。其不(bu)合(he)格(ge)的(de)(de)(de)(de)(de)主要原(yuan)因是(shi)使(shi)用了再生料生產(chan)，以(yi)降低(di)產(chan)品成本，二是(shi)不(bu)具備生產(chan)資格(ge)小型企業。

4、導(dao)(dao)體電(dian)(dian)阻(zu)不(bu)合格(ge)的(de)(de)電(dian)(dian)線(xian)。導(dao)(dao)體電(dian)(dian)阻(zu)主(zhu)要是考核(he)電(dian)(dian)線(xian)電(dian)(dian)纜的(de)(de)導(dao)(dao)體材料以及截面是否符合的(de)(de)重要指標(biao)。當導(dao)(dao)體電(dian)(dian)阻(zu)超(chao)標(biao)時，就增大了電(dian)(dian)流(liu)在線(xian)路上通過時的(de)(de)損耗，加劇了電(dian)(dian)線(xian)電(dian)(dian)纜的(de)(de)發(fa)熱。導(dao)(dao)體電(dian)(dian)阻(zu)不(bu)合格(ge)的(de)(de)原因(yin)，主(zhu)要進企業為(wei)了降低成本(ben)，將占原材料成本(ben)80%的(de)(de)銅(tong)(tong)材縮水，要么(me)降低導(dao)(dao)體的(de)(de)截面積，要么(me)使(shi)(shi)用(yong)含雜質過高的(de)(de)再(zai)生銅(tong)(tong)，這(zhe)樣(yang)致使(shi)(shi)電(dian)(dian)線(xian)電(dian)(dian)纜的(de)(de)導(dao)(dao)體電(dian)(dian)阻(zu)嚴重超(chao)標(biao)，在使(shi)(shi)用(yong)過程中除易引(yin)發(fa)火災，還會(hui)加速包(bao)覆在電(dian)(dian)線(xian)外的(de)(de)絕緣(yuan)層(ceng)的(de)(de)老化。

在購買電線電纜的過程(cheng)中，消費者應注意以(yi)下幾個(ge)事(shi)

第一、要觀察電線的(de)外(wai)觀。合格(ge)產品(pin)的(de)絕緣（護(hu)套(tao)）層柔軟、有韌(ren)性和伸縮性、表面層緊密(mi)、光滑、無(wu)粗糙感。如果包裹電線的(de)塑料很容易被剝去，則(ze)存在塑料強度不(bu)夠的(de)問(wen)題。

第二、要看電線(xian)的(de)截面。合格(ge)產品的(de)銅芯(xin)(xin)或鋁(lv)(lv)芯(xin)(xin)表(biao)面應該具有(you)金屬(shu)光澤，表(biao)面發黑的(de)銅或表(biao)面發白的(de)鋁(lv)(lv)說明已被(bei)氧(yang)化。

第三、在購買電線時應(ying)注意(yi)查看質量(liang)合格證書。如果電線的質量(liang)合格，那么其電線質量(liang)應(ying)該也受過檢驗，不會有太大的問題(ti)。
