不合格(ge)電(dian)線(xian)電(dian)纜(lan)的(de)危害(hai)

電(dian)(dian)線電(dian)(dian)纜是用于傳(chuan)輸(shu)電(dian)(dian)力、傳(chuan)輸(shu)信息和實現(xian)電(dian)(dian)磁能量轉(zhuan)換的一大類電(dian)(dian)工產品(pin)。在抽查(cha)過程中(zhong)，發現(xian)了大量的不合格產品(pin)，這些劣質(zhi)產品(pin)給電(dian)(dian)力系統正常運行埋下諸多隱(yin)患。

1、標(biao)(biao)志(zhi)不(bu)合(he)(he)格的(de)電(dian)線(xian)電(dian)纜(lan)。標(biao)(biao)志(zhi)是電(dian)線(xian)電(dian)纜(lan)使(shi)用(yong)識別產品(pin)基本信息的(de)主要途徑，根據標(biao)(biao)準(zhun)規定(ding)(ding)標(biao)(biao)志(zhi)的(de)主要內容是：產品(pin)型號、規格、標(biao)(biao)準(zhun)號、廠(chang)名、產地(di)等在一定(ding)(ding)的(de)標(biao)(biao)示間(jian)距內，當(dang)標(biao)(biao)志(zhi)不(bu)合(he)(he)格時(shi)，會(hui)造(zao)成施工人員識別錯誤，嚴重時(shi)會(hui)引發電(dian)氣事(shi)故。

2、結(jie)構(gou)(gou)尺寸(cun)不(bu)合格(ge)的電(dian)線(xian)(xian)電(dian)纜(lan)(lan)。結(jie)構(gou)(gou)尺寸(cun)的主要問題(ti)是護(hu)套厚(hou)度(du)(du)，絕緣厚(hou)度(du)(du)，當(dang)電(dian)纜(lan)(lan)的護(hu)套和(he)絕緣厚(hou)度(du)(du)不(bu)達(da)標(biao)時(shi)，致使(shi)電(dian)線(xian)(xian)電(dian)纜(lan)(lan)耐電(dian)氣強度(du)(du)會嚴重降低(di)，導(dao)致電(dian)線(xian)(xian)電(dian)纜(lan)(lan)的使(shi)用壽命縮(suo)短，嚴重時(shi)可導(dao)致電(dian)線(xian)(xian)電(dian)纜(lan)(lan)被擊穿，絕緣（護(hu)套）層(ceng)起不(bu)到正常(chang)保護(hu)作(zuo)用，從而發生電(dian)氣短路和(he)火災等現象(xiang)。

3、護套式絕(jue)緣老化前(qian)的(de)抗張(zhang)強度(du)(du)、伸(shen)(shen)長(chang)(chang)率(lv)合(he)(he)格(ge)的(de)電(dian)線電(dian)纜(lan)。絕(jue)緣護套老化前(qian)的(de)抗張(zhang)強度(du)(du)、伸(shen)(shen)長(chang)(chang)率(lv)不(bu)合(he)(he)格(ge)直(zhi)接大大縮短(duan)電(dian)線電(dian)纜(lan)的(de)工(gong)作用壽命，而(er)且(qie)在施工(gong)或在長(chang)(chang)時(shi)間(jian)通(tong)電(dian)且(qie)溫度(du)(du)較高的(de)環境中(zhong)，極易(yi)出現絕(jue)緣體斷裂，致使帶電(dian)導體裸露(lu)，發生(sheng)能觸電(dian)式短(duan)路危險。其不(bu)合(he)(he)格(ge)的(de)主要原因(yin)是使用了再生(sheng)料生(sheng)產(chan)，以降低產(chan)品成本，二是不(bu)具(ju)備生(sheng)產(chan)資格(ge)小型企業。

4、導(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)不(bu)合格(ge)的(de)電(dian)(dian)(dian)(dian)線(xian)。導(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)主(zhu)要(yao)是考核電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)導(dao)體(ti)(ti)材(cai)料(liao)以(yi)及截(jie)(jie)面(mian)(mian)是否符合的(de)重(zhong)要(yao)指標。當導(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)超(chao)標時，就(jiu)增大了電(dian)(dian)(dian)(dian)流在(zai)線(xian)路上通(tong)過(guo)時的(de)損耗，加劇了電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)發熱。導(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)不(bu)合格(ge)的(de)原因，主(zhu)要(yao)進企業為了降低成本(ben)，將占原材(cai)料(liao)成本(ben)80%的(de)銅(tong)材(cai)縮(suo)水，要(yao)么降低導(dao)體(ti)(ti)的(de)截(jie)(jie)面(mian)(mian)積，要(yao)么使(shi)用含雜(za)質過(guo)高的(de)再生銅(tong)，這樣致(zhi)使(shi)電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)導(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)嚴(yan)重(zhong)超(chao)標，在(zai)使(shi)用過(guo)程中除易引(yin)發火(huo)災，還(huan)會加速包覆在(zai)電(dian)(dian)(dian)(dian)線(xian)外的(de)絕緣(yuan)層(ceng)的(de)老化。

在(zai)購買電(dian)線電(dian)纜(lan)的過程中，消費者應注意以下(xia)幾個事

第一(yi)、要觀察電線(xian)的外(wai)觀。合格產品的絕(jue)緣(yuan)（護套(tao)）層柔軟、有韌性和伸縮性、表面層緊密、光(guang)滑、無粗糙感。如果包裹電線(xian)的塑料(liao)很容易被剝去，則存(cun)在(zai)塑料(liao)強度不夠的問(wen)題。

第(di)二、要(yao)看電(dian)線的(de)(de)截面。合格產品(pin)的(de)(de)銅芯(xin)或鋁(lv)芯(xin)表面應該具(ju)有(you)金屬光(guang)澤，表面發黑的(de)(de)銅或表面發白的(de)(de)鋁(lv)說明(ming)已被氧化(hua)。

第三、在購買(mai)電線(xian)時(shi)應注意(yi)查看(kan)質量(liang)合格證(zheng)書(shu)。如果電線(xian)的(de)質量(liang)合格，那(nei)么(me)其電線(xian)質量(liang)應該也受(shou)過(guo)檢(jian)驗，不會有(you)太大的(de)問題(ti)。
