不(bu)合格電(dian)線電(dian)纜(lan)的(de)危害

電(dian)線電(dian)纜是用于傳(chuan)輸(shu)電(dian)力、傳(chuan)輸(shu)信(xin)息和實現電(dian)磁能量轉(zhuan)換的一大類電(dian)工產(chan)品(pin)。在抽查過程中，發現了大量的不合格產(chan)品(pin)，這些劣質產(chan)品(pin)給電(dian)力系(xi)統正(zheng)常運行(xing)埋(mai)下諸多隱(yin)患(huan)。

1、標(biao)志(zhi)不(bu)合格(ge)的電(dian)線電(dian)纜。標(biao)志(zhi)是電(dian)線電(dian)纜使用識別產品基本信息的主要(yao)途徑，根據標(biao)準(zhun)規定標(biao)志(zhi)的主要(yao)內容是：產品型號、規格(ge)、標(biao)準(zhun)號、廠(chang)名、產地等在一定的標(biao)示間距內，當標(biao)志(zhi)不(bu)合格(ge)時(shi)，會造成施工人員識別錯誤(wu)，嚴重時(shi)會引發電(dian)氣事故(gu)。

2、結構(gou)尺寸不合格(ge)的電(dian)(dian)(dian)線電(dian)(dian)(dian)纜。結構(gou)尺寸的主(zhu)要問題(ti)是護套厚度(du)(du)，絕(jue)(jue)緣(yuan)厚度(du)(du)，當電(dian)(dian)(dian)纜的護套和絕(jue)(jue)緣(yuan)厚度(du)(du)不達標時，致使電(dian)(dian)(dian)線電(dian)(dian)(dian)纜耐(nai)電(dian)(dian)(dian)氣(qi)強度(du)(du)會嚴(yan)(yan)重降低，導(dao)(dao)致電(dian)(dian)(dian)線電(dian)(dian)(dian)纜的使用壽命(ming)縮(suo)短(duan)，嚴(yan)(yan)重時可導(dao)(dao)致電(dian)(dian)(dian)線電(dian)(dian)(dian)纜被(bei)擊穿，絕(jue)(jue)緣(yuan)（護套）層(ceng)起不到正常(chang)保(bao)護作用，從而發生電(dian)(dian)(dian)氣(qi)短(duan)路和火災等現(xian)象(xiang)。

3、護套式(shi)絕緣(yuan)(yuan)老化前的(de)(de)(de)(de)抗張(zhang)(zhang)強度(du)、伸長(chang)率合(he)(he)格(ge)(ge)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)(dian)纜。絕緣(yuan)(yuan)護套老化前的(de)(de)(de)(de)抗張(zhang)(zhang)強度(du)、伸長(chang)率不合(he)(he)格(ge)(ge)直接大大縮短(duan)電(dian)(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)(dian)纜的(de)(de)(de)(de)工(gong)作(zuo)用壽命，而且在施工(gong)或在長(chang)時間通(tong)電(dian)(dian)(dian)(dian)(dian)且溫度(du)較高的(de)(de)(de)(de)環境中，極易出現絕緣(yuan)(yuan)體斷(duan)裂，致使(shi)(shi)帶電(dian)(dian)(dian)(dian)(dian)導體裸露，發(fa)生(sheng)能觸電(dian)(dian)(dian)(dian)(dian)式(shi)短(duan)路危(wei)險。其不合(he)(he)格(ge)(ge)的(de)(de)(de)(de)主要原因是使(shi)(shi)用了再生(sheng)料生(sheng)產，以(yi)降低產品(pin)成(cheng)本(ben)，二(er)是不具(ju)備生(sheng)產資格(ge)(ge)小型企業(ye)。

4、導(dao)(dao)體(ti)(ti)電(dian)(dian)阻(zu)不合(he)格(ge)(ge)的(de)(de)電(dian)(dian)線(xian)。導(dao)(dao)體(ti)(ti)電(dian)(dian)阻(zu)主(zhu)要(yao)(yao)(yao)是(shi)考核電(dian)(dian)線(xian)電(dian)(dian)纜(lan)的(de)(de)導(dao)(dao)體(ti)(ti)材料(liao)以(yi)及截面(mian)是(shi)否符合(he)的(de)(de)重要(yao)(yao)(yao)指(zhi)標。當導(dao)(dao)體(ti)(ti)電(dian)(dian)阻(zu)超標時，就增大了(le)電(dian)(dian)流在(zai)線(xian)路(lu)上通(tong)過(guo)時的(de)(de)損(sun)耗，加(jia)(jia)劇了(le)電(dian)(dian)線(xian)電(dian)(dian)纜(lan)的(de)(de)發熱。導(dao)(dao)體(ti)(ti)電(dian)(dian)阻(zu)不合(he)格(ge)(ge)的(de)(de)原因(yin)，主(zhu)要(yao)(yao)(yao)進(jin)企業為了(le)降(jiang)低成本，將占原材料(liao)成本80%的(de)(de)銅(tong)材縮水，要(yao)(yao)(yao)么(me)降(jiang)低導(dao)(dao)體(ti)(ti)的(de)(de)截面(mian)積，要(yao)(yao)(yao)么(me)使用含雜質過(guo)高的(de)(de)再生銅(tong)，這樣(yang)致使電(dian)(dian)線(xian)電(dian)(dian)纜(lan)的(de)(de)導(dao)(dao)體(ti)(ti)電(dian)(dian)阻(zu)嚴重超標，在(zai)使用過(guo)程中除(chu)易引發火(huo)災，還會加(jia)(jia)速包覆在(zai)電(dian)(dian)線(xian)外的(de)(de)絕緣層的(de)(de)老化。

在購(gou)買電(dian)線電(dian)纜的過程中，消費者應注意(yi)以(yi)下幾個事

第一、要觀察電(dian)線的(de)外觀。合格產品的(de)絕緣（護(hu)套）層(ceng)柔軟(ruan)、有韌性(xing)和伸(shen)縮性(xing)、表面層(ceng)緊密、光滑、無粗糙感。如(ru)果包裹電(dian)線的(de)塑料很容易被(bei)剝去，則存在塑料強(qiang)度(du)不夠(gou)的(de)問題。

第二(er)、要看電線的截面(mian)。合格產品(pin)的銅(tong)芯或鋁芯表面(mian)應該具有金屬光澤，表面(mian)發黑的銅(tong)或表面(mian)發白的鋁說明已(yi)被(bei)氧(yang)化。

第三(san)、在購(gou)買電線(xian)時應(ying)注意查看(kan)質(zhi)量(liang)(liang)合(he)格證書。如果電線(xian)的質(zhi)量(liang)(liang)合(he)格，那么其(qi)電線(xian)質(zhi)量(liang)(liang)應(ying)該也受過檢驗，不會有(you)太大(da)的問(wen)題。
