不(bu)合(he)格電線電纜的危害

電(dian)線電(dian)纜是用于傳(chuan)輸電(dian)力(li)、傳(chuan)輸信息和實現電(dian)磁能量轉換的一大類電(dian)工產(chan)品(pin)。在抽(chou)查過程中，發(fa)現了大量的不合(he)格產(chan)品(pin)，這(zhe)些劣質產(chan)品(pin)給電(dian)力(li)系(xi)統正常運行(xing)埋下(xia)諸多隱患。

1、標(biao)志不合(he)格(ge)(ge)的電(dian)線電(dian)纜(lan)。標(biao)志是電(dian)線電(dian)纜(lan)使用識別產品基本信息的主要(yao)途徑，根據標(biao)準規定標(biao)志的主要(yao)內容是：產品型號、規格(ge)(ge)、標(biao)準號、廠名(ming)、產地(di)等(deng)在一定的標(biao)示間(jian)距內，當標(biao)志不合(he)格(ge)(ge)時(shi)，會造成施(shi)工人員識別錯(cuo)誤(wu)，嚴重時(shi)會引發電(dian)氣事故。

2、結(jie)(jie)構尺寸不合格的(de)(de)(de)電(dian)線(xian)(xian)電(dian)纜。結(jie)(jie)構尺寸的(de)(de)(de)主要問題是護(hu)(hu)套(tao)厚(hou)(hou)度(du)，絕(jue)緣厚(hou)(hou)度(du)，當電(dian)纜的(de)(de)(de)護(hu)(hu)套(tao)和絕(jue)緣厚(hou)(hou)度(du)不達標時(shi)，致使電(dian)線(xian)(xian)電(dian)纜耐(nai)電(dian)氣(qi)強度(du)會嚴重(zhong)降低(di)，導(dao)致電(dian)線(xian)(xian)電(dian)纜的(de)(de)(de)使用壽命(ming)縮短(duan)，嚴重(zhong)時(shi)可導(dao)致電(dian)線(xian)(xian)電(dian)纜被擊穿，絕(jue)緣（護(hu)(hu)套(tao)）層(ceng)起(qi)不到正(zheng)常保護(hu)(hu)作用，從(cong)而發(fa)生(sheng)電(dian)氣(qi)短(duan)路(lu)和火災等現象。

3、護套式絕緣(yuan)(yuan)老(lao)化前的(de)抗張(zhang)強度、伸長(chang)(chang)率合格(ge)的(de)電(dian)線(xian)電(dian)纜(lan)。絕緣(yuan)(yuan)護套老(lao)化前的(de)抗張(zhang)強度、伸長(chang)(chang)率不合格(ge)直接大大縮短電(dian)線(xian)電(dian)纜(lan)的(de)工作用壽(shou)命，而且在施工或在長(chang)(chang)時間通電(dian)且溫度較高的(de)環境中，極易出(chu)現絕緣(yuan)(yuan)體斷裂，致使(shi)帶電(dian)導體裸露，發生(sheng)能觸電(dian)式短路(lu)危險(xian)。其不合格(ge)的(de)主要原因是(shi)使(shi)用了(le)再(zai)生(sheng)料(liao)生(sheng)產，以降(jiang)低產品成(cheng)本(ben)，二是(shi)不具備生(sheng)產資格(ge)小型企業。

4、導(dao)(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)阻不(bu)合(he)格(ge)的(de)(de)(de)電(dian)(dian)(dian)線(xian)(xian)。導(dao)(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)阻主(zhu)要(yao)是(shi)考核電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜的(de)(de)(de)導(dao)(dao)(dao)體(ti)(ti)材料以及截面是(shi)否符合(he)的(de)(de)(de)重要(yao)指(zhi)標。當導(dao)(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)阻超標時，就增(zeng)大了(le)電(dian)(dian)(dian)流(liu)在線(xian)(xian)路上通過時的(de)(de)(de)損耗，加劇了(le)電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜的(de)(de)(de)發(fa)熱。導(dao)(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)阻不(bu)合(he)格(ge)的(de)(de)(de)原因(yin)，主(zhu)要(yao)進企業(ye)為了(le)降(jiang)(jiang)低成(cheng)本(ben)，將占(zhan)原材料成(cheng)本(ben)80%的(de)(de)(de)銅(tong)材縮水，要(yao)么降(jiang)(jiang)低導(dao)(dao)(dao)體(ti)(ti)的(de)(de)(de)截面積，要(yao)么使(shi)用(yong)含雜(za)質過高的(de)(de)(de)再生銅(tong)，這樣致使(shi)電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜的(de)(de)(de)導(dao)(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)阻嚴(yan)重超標，在使(shi)用(yong)過程中除(chu)易引發(fa)火災，還會加速包(bao)覆在電(dian)(dian)(dian)線(xian)(xian)外(wai)的(de)(de)(de)絕(jue)緣層(ceng)的(de)(de)(de)老化。

在購買電線電纜的過程中，消費者(zhe)應注意(yi)以下幾個事

第一、要觀(guan)察電線的(de)外觀(guan)。合格產品的(de)絕緣（護套）層(ceng)(ceng)柔軟、有韌性和(he)伸縮性、表面層(ceng)(ceng)緊(jin)密、光(guang)滑(hua)、無(wu)粗糙感。如果包(bao)裹電線的(de)塑(su)料很容易被剝去，則(ze)存(cun)在(zai)塑(su)料強度不夠的(de)問題。

第二、要看電線的(de)截面(mian)(mian)。合格產品的(de)銅芯或(huo)鋁(lv)芯表(biao)(biao)面(mian)(mian)應該(gai)具有金屬光澤，表(biao)(biao)面(mian)(mian)發(fa)黑的(de)銅或(huo)表(biao)(biao)面(mian)(mian)發(fa)白的(de)鋁(lv)說(shuo)明已被氧化。

第(di)三、在購(gou)買(mai)電線(xian)(xian)時應注意(yi)查(cha)看質量合格證(zheng)書。如(ru)果電線(xian)(xian)的質量合格，那(nei)么其(qi)電線(xian)(xian)質量應該也(ye)受過檢(jian)驗，不會有太大的問題(ti)。
