不(bu)合格電線電纜的(de)危害

電(dian)(dian)線電(dian)(dian)纜是用(yong)于傳輸電(dian)(dian)力、傳輸信息(xi)和實現(xian)電(dian)(dian)磁(ci)能量轉換的一大(da)類電(dian)(dian)工產品。在抽查過程中，發現(xian)了大(da)量的不合格產品，這些劣質產品給電(dian)(dian)力系(xi)統正常運(yun)行埋(mai)下諸多隱(yin)患。

1、標(biao)(biao)志(zhi)不合(he)格(ge)的(de)電線(xian)電纜(lan)。標(biao)(biao)志(zhi)是(shi)電線(xian)電纜(lan)使用識別產品基本信息的(de)主要途(tu)徑，根據標(biao)(biao)準(zhun)規(gui)定標(biao)(biao)志(zhi)的(de)主要內(nei)容是(shi)：產品型號、規(gui)格(ge)、標(biao)(biao)準(zhun)號、廠名、產地等在一定的(de)標(biao)(biao)示間距內(nei)，當標(biao)(biao)志(zhi)不合(he)格(ge)時(shi)，會造成施(shi)工人員識別錯(cuo)誤，嚴(yan)重時(shi)會引發電氣事故。

2、結(jie)構(gou)(gou)尺(chi)寸不合格的(de)(de)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜。結(jie)構(gou)(gou)尺(chi)寸的(de)(de)主要問題是護套厚(hou)度(du)(du)，絕緣厚(hou)度(du)(du)，當(dang)電(dian)(dian)(dian)纜的(de)(de)護套和(he)絕緣厚(hou)度(du)(du)不達標時，致使電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜耐電(dian)(dian)(dian)氣強度(du)(du)會嚴重(zhong)降低，導(dao)致電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜的(de)(de)使用(yong)壽命縮短，嚴重(zhong)時可導(dao)致電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜被(bei)擊(ji)穿，絕緣（護套）層起不到正(zheng)常保護作用(yong)，從而發生電(dian)(dian)(dian)氣短路和(he)火災等(deng)現象。

3、護套式(shi)絕(jue)(jue)(jue)緣老化前的(de)(de)抗張(zhang)(zhang)強度(du)、伸長率(lv)合(he)格(ge)的(de)(de)電(dian)(dian)線電(dian)(dian)纜(lan)。絕(jue)(jue)(jue)緣護套老化前的(de)(de)抗張(zhang)(zhang)強度(du)、伸長率(lv)不合(he)格(ge)直接大大縮短(duan)電(dian)(dian)線電(dian)(dian)纜(lan)的(de)(de)工(gong)作(zuo)用壽命(ming)，而且在施工(gong)或在長時間(jian)通電(dian)(dian)且溫度(du)較高的(de)(de)環境中，極易出(chu)現絕(jue)(jue)(jue)緣體(ti)斷裂，致使帶(dai)電(dian)(dian)導體(ti)裸露，發(fa)生(sheng)能觸(chu)電(dian)(dian)式(shi)短(duan)路危險。其不合(he)格(ge)的(de)(de)主(zhu)要原因是使用了再生(sheng)料生(sheng)產，以降低產品成本，二是不具(ju)備生(sheng)產資格(ge)小型企業。

4、導(dao)(dao)體(ti)電(dian)(dian)(dian)阻(zu)不合格的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)線(xian)。導(dao)(dao)體(ti)電(dian)(dian)(dian)阻(zu)主要是考核電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)的(de)(de)(de)(de)(de)(de)導(dao)(dao)體(ti)材料以及截(jie)面是否(fou)符合的(de)(de)(de)(de)(de)(de)重(zhong)要指標(biao)。當導(dao)(dao)體(ti)電(dian)(dian)(dian)阻(zu)超標(biao)時，就增大了(le)電(dian)(dian)(dian)流在線(xian)路上(shang)通過(guo)時的(de)(de)(de)(de)(de)(de)損耗，加劇了(le)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)的(de)(de)(de)(de)(de)(de)發熱。導(dao)(dao)體(ti)電(dian)(dian)(dian)阻(zu)不合格的(de)(de)(de)(de)(de)(de)原(yuan)因，主要進企業為了(le)降低成本(ben)，將占(zhan)原(yuan)材料成本(ben)80%的(de)(de)(de)(de)(de)(de)銅材縮水(shui)，要么降低導(dao)(dao)體(ti)的(de)(de)(de)(de)(de)(de)截(jie)面積，要么使用(yong)含雜(za)質過(guo)高的(de)(de)(de)(de)(de)(de)再(zai)生銅，這樣(yang)致使電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)的(de)(de)(de)(de)(de)(de)導(dao)(dao)體(ti)電(dian)(dian)(dian)阻(zu)嚴重(zhong)超標(biao)，在使用(yong)過(guo)程中除易引發火(huo)災，還(huan)會加速(su)包(bao)覆在電(dian)(dian)(dian)線(xian)外的(de)(de)(de)(de)(de)(de)絕緣層(ceng)的(de)(de)(de)(de)(de)(de)老化。

在購(gou)買電線電纜的過程中，消(xiao)費(fei)者應注意以下(xia)幾個事

第(di)一(yi)、要(yao)觀(guan)察電線(xian)的(de)外觀(guan)。合格產品的(de)絕緣（護套）層柔軟、有(you)韌性和伸縮性、表面層緊密、光滑、無粗糙感(gan)。如(ru)果包裹電線(xian)的(de)塑料很(hen)容易被剝去，則(ze)存在塑料強(qiang)度不夠的(de)問題。

第二、要看電線(xian)的(de)截面。合格產品(pin)的(de)銅芯或(huo)鋁(lv)芯表(biao)面應該具有(you)金(jin)屬光澤，表(biao)面發(fa)黑的(de)銅或(huo)表(biao)面發(fa)白的(de)鋁(lv)說明已被氧化。

第三、在購買電線時應(ying)注意查看質(zhi)量合格證書。如果電線的質(zhi)量合格，那么其電線質(zhi)量應(ying)該也受過檢(jian)驗，不會有(you)太大的問題。
