不合(he)格電線(xian)電纜的危害

電(dian)(dian)(dian)線電(dian)(dian)(dian)纜是用(yong)于傳(chuan)輸電(dian)(dian)(dian)力(li)、傳(chuan)輸信息和(he)實現電(dian)(dian)(dian)磁能量轉換的(de)一大(da)類電(dian)(dian)(dian)工產品(pin)。在抽查(cha)過程中，發(fa)現了大(da)量的(de)不合格(ge)產品(pin)，這些劣質產品(pin)給(gei)電(dian)(dian)(dian)力(li)系(xi)統正常運(yun)行埋下諸多隱(yin)患。

1、標(biao)志不合(he)(he)格(ge)(ge)的(de)電線電纜(lan)。標(biao)志是電線電纜(lan)使用識(shi)別產(chan)品(pin)基本(ben)信息的(de)主要途徑，根(gen)據標(biao)準(zhun)規(gui)定標(biao)志的(de)主要內容(rong)是：產(chan)品(pin)型號、規(gui)格(ge)(ge)、標(biao)準(zhun)號、廠名、產(chan)地等在一定的(de)標(biao)示間(jian)距內，當標(biao)志不合(he)(he)格(ge)(ge)時(shi)，會(hui)造成施(shi)工人員(yuan)識(shi)別錯誤，嚴重時(shi)會(hui)引發電氣事故。

2、結(jie)構尺寸不合格的(de)(de)(de)電(dian)線(xian)電(dian)纜(lan)(lan)。結(jie)構尺寸的(de)(de)(de)主要問題是護(hu)套(tao)厚(hou)(hou)度(du)，絕(jue)緣(yuan)厚(hou)(hou)度(du)，當(dang)電(dian)纜(lan)(lan)的(de)(de)(de)護(hu)套(tao)和絕(jue)緣(yuan)厚(hou)(hou)度(du)不達標時(shi)，致使電(dian)線(xian)電(dian)纜(lan)(lan)耐(nai)電(dian)氣(qi)強度(du)會嚴(yan)重(zhong)降低，導致電(dian)線(xian)電(dian)纜(lan)(lan)的(de)(de)(de)使用(yong)(yong)壽命縮短，嚴(yan)重(zhong)時(shi)可導致電(dian)線(xian)電(dian)纜(lan)(lan)被擊穿，絕(jue)緣(yuan)（護(hu)套(tao)）層起不到正常(chang)保護(hu)作用(yong)(yong)，從(cong)而發生電(dian)氣(qi)短路(lu)和火災等現象。

3、護套(tao)式(shi)(shi)絕(jue)(jue)緣(yuan)老(lao)(lao)化前的抗張強(qiang)度(du)、伸(shen)長(chang)(chang)率合(he)格(ge)的電(dian)線電(dian)纜(lan)。絕(jue)(jue)緣(yuan)護套(tao)老(lao)(lao)化前的抗張強(qiang)度(du)、伸(shen)長(chang)(chang)率不合(he)格(ge)直接(jie)大大縮短電(dian)線電(dian)纜(lan)的工(gong)作用壽命，而且在(zai)施工(gong)或在(zai)長(chang)(chang)時間通電(dian)且溫度(du)較高的環境中(zhong)，極易出現(xian)絕(jue)(jue)緣(yuan)體斷裂，致使帶電(dian)導(dao)體裸露，發(fa)生(sheng)能觸(chu)電(dian)式(shi)(shi)短路(lu)危險。其不合(he)格(ge)的主要(yao)原因是使用了再生(sheng)料(liao)生(sheng)產(chan)，以(yi)降低產(chan)品成(cheng)本，二是不具備生(sheng)產(chan)資格(ge)小型企(qi)業(ye)。

4、導(dao)(dao)(dao)體(ti)電阻(zu)(zu)(zu)不(bu)合(he)格的(de)(de)(de)電線(xian)(xian)。導(dao)(dao)(dao)體(ti)電阻(zu)(zu)(zu)主(zhu)要(yao)(yao)是(shi)考(kao)核電線(xian)(xian)電纜(lan)的(de)(de)(de)導(dao)(dao)(dao)體(ti)材(cai)料(liao)以及截面(mian)是(shi)否符合(he)的(de)(de)(de)重要(yao)(yao)指(zhi)標。當導(dao)(dao)(dao)體(ti)電阻(zu)(zu)(zu)超標時，就(jiu)增(zeng)大了(le)電流(liu)在線(xian)(xian)路上通(tong)過(guo)時的(de)(de)(de)損(sun)耗，加(jia)劇(ju)了(le)電線(xian)(xian)電纜(lan)的(de)(de)(de)發熱(re)。導(dao)(dao)(dao)體(ti)電阻(zu)(zu)(zu)不(bu)合(he)格的(de)(de)(de)原因，主(zhu)要(yao)(yao)進(jin)企業為了(le)降低(di)成本，將(jiang)占原材(cai)料(liao)成本80%的(de)(de)(de)銅(tong)材(cai)縮水，要(yao)(yao)么降低(di)導(dao)(dao)(dao)體(ti)的(de)(de)(de)截面(mian)積，要(yao)(yao)么使用(yong)含雜質(zhi)過(guo)高的(de)(de)(de)再生銅(tong)，這樣(yang)致使電線(xian)(xian)電纜(lan)的(de)(de)(de)導(dao)(dao)(dao)體(ti)電阻(zu)(zu)(zu)嚴重超標，在使用(yong)過(guo)程中除(chu)易引發火災，還會加(jia)速(su)包覆在電線(xian)(xian)外的(de)(de)(de)絕緣層的(de)(de)(de)老化。

在購買電線電纜的(de)過程中(zhong)，消(xiao)費者(zhe)應(ying)注意以下幾(ji)個(ge)事

第(di)一、要觀察電線(xian)的(de)外(wai)觀。合格產品的(de)絕(jue)緣（護(hu)套）層(ceng)柔軟、有韌性和(he)伸(shen)縮(suo)性、表面層(ceng)緊密、光滑、無粗糙感。如果包裹電線(xian)的(de)塑料(liao)很(hen)容易被剝(bo)去，則存在塑料(liao)強度(du)不夠的(de)問題。

第二、要看電線的截面(mian)(mian)。合格產品的銅(tong)芯或(huo)鋁芯表(biao)面(mian)(mian)應(ying)該具有(you)金屬(shu)光澤，表(biao)面(mian)(mian)發黑(hei)的銅(tong)或(huo)表(biao)面(mian)(mian)發白的鋁說明已被氧化。

第三、在購買電(dian)線時(shi)應注意查看質量(liang)合格證書。如果電(dian)線的質量(liang)合格，那么(me)其電(dian)線質量(liang)應該也受過檢驗，不會有太大的問題(ti)。
