不合格電(dian)線電(dian)纜(lan)的危害(hai)

電(dian)(dian)線電(dian)(dian)纜是(shi)用于傳輸(shu)電(dian)(dian)力(li)、傳輸(shu)信(xin)息和實(shi)現電(dian)(dian)磁能量轉換的一大(da)類電(dian)(dian)工(gong)產(chan)品。在抽(chou)查過程(cheng)中，發現了(le)大(da)量的不合格產(chan)品，這些劣(lie)質(zhi)產(chan)品給電(dian)(dian)力(li)系(xi)統(tong)正(zheng)常運行(xing)埋下諸多隱患(huan)。

1、標(biao)志不(bu)(bu)合(he)格(ge)的電線電纜。標(biao)志是(shi)電線電纜使用識(shi)別產品基本信息的主要途徑，根(gen)據(ju)標(biao)準(zhun)規(gui)定標(biao)志的主要內容是(shi)：產品型號、規(gui)格(ge)、標(biao)準(zhun)號、廠名、產地等(deng)在一定的標(biao)示間距內，當(dang)標(biao)志不(bu)(bu)合(he)格(ge)時，會(hui)造成施工人員識(shi)別錯誤，嚴重(zhong)時會(hui)引(yin)發電氣(qi)事故。

2、結構尺寸不(bu)合格的(de)(de)電(dian)線(xian)電(dian)纜。結構尺寸的(de)(de)主要問(wen)題(ti)是護套厚度(du)(du)，絕(jue)緣(yuan)厚度(du)(du)，當電(dian)纜的(de)(de)護套和絕(jue)緣(yuan)厚度(du)(du)不(bu)達標(biao)時，致(zhi)使(shi)電(dian)線(xian)電(dian)纜耐電(dian)氣強度(du)(du)會嚴(yan)重降低，導致(zhi)電(dian)線(xian)電(dian)纜的(de)(de)使(shi)用壽命縮短(duan)，嚴(yan)重時可(ke)導致(zhi)電(dian)線(xian)電(dian)纜被擊穿，絕(jue)緣(yuan)（護套）層起不(bu)到正(zheng)常保護作用，從(cong)而發生電(dian)氣短(duan)路和火災等現象。

3、護套(tao)(tao)式絕(jue)(jue)緣(yuan)老(lao)化(hua)前(qian)的(de)抗張強度(du)(du)、伸長(chang)率(lv)合(he)格(ge)的(de)電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜。絕(jue)(jue)緣(yuan)護套(tao)(tao)老(lao)化(hua)前(qian)的(de)抗張強度(du)(du)、伸長(chang)率(lv)不合(he)格(ge)直接大大縮短電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜的(de)工作用(yong)壽(shou)命，而且(qie)在施工或在長(chang)時(shi)間通(tong)電(dian)(dian)(dian)(dian)且(qie)溫度(du)(du)較高的(de)環境中(zhong)，極易出現絕(jue)(jue)緣(yuan)體(ti)(ti)斷裂，致使帶電(dian)(dian)(dian)(dian)導體(ti)(ti)裸露(lu)，發生能觸電(dian)(dian)(dian)(dian)式短路(lu)危險。其不合(he)格(ge)的(de)主要原因是使用(yong)了再生料(liao)生產(chan)(chan)，以降低產(chan)(chan)品成(cheng)本(ben)，二是不具備(bei)生產(chan)(chan)資格(ge)小型企(qi)業。

4、導(dao)(dao)體電(dian)(dian)(dian)阻(zu)(zu)不合(he)格的電(dian)(dian)(dian)線(xian)(xian)。導(dao)(dao)體電(dian)(dian)(dian)阻(zu)(zu)主(zhu)(zhu)要(yao)是考核電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜的導(dao)(dao)體材料(liao)以及截(jie)面是否符合(he)的重要(yao)指標(biao)。當導(dao)(dao)體電(dian)(dian)(dian)阻(zu)(zu)超(chao)(chao)標(biao)時，就增(zeng)大了(le)(le)電(dian)(dian)(dian)流在(zai)(zai)線(xian)(xian)路(lu)上(shang)通(tong)過時的損(sun)耗，加(jia)劇了(le)(le)電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜的發(fa)熱(re)。導(dao)(dao)體電(dian)(dian)(dian)阻(zu)(zu)不合(he)格的原(yuan)因，主(zhu)(zhu)要(yao)進企(qi)業為了(le)(le)降(jiang)低(di)成本，將占原(yuan)材料(liao)成本80%的銅材縮(suo)水(shui)，要(yao)么(me)降(jiang)低(di)導(dao)(dao)體的截(jie)面積(ji)，要(yao)么(me)使(shi)用含雜(za)質過高的再生銅，這樣致使(shi)電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜的導(dao)(dao)體電(dian)(dian)(dian)阻(zu)(zu)嚴重超(chao)(chao)標(biao)，在(zai)(zai)使(shi)用過程中除易引發(fa)火(huo)災，還(huan)會加(jia)速包覆在(zai)(zai)電(dian)(dian)(dian)線(xian)(xian)外(wai)的絕(jue)緣層(ceng)的老化。

在購買電線電纜的過程中，消(xiao)費(fei)者應注意以(yi)下幾個事

第一、要觀察電(dian)線的外觀。合(he)格產品的絕緣（護套）層(ceng)柔軟(ruan)、有韌性和(he)伸縮性、表面(mian)層(ceng)緊(jin)密、光滑、無粗(cu)糙感。如果包裹電(dian)線的塑料很容易(yi)被(bei)剝(bo)去(qu)，則存在塑料強度不夠的問題。

第二、要(yao)看電(dian)線的(de)截面。合(he)格產品的(de)銅(tong)芯(xin)或鋁芯(xin)表面應該具(ju)有金屬光(guang)澤，表面發(fa)(fa)黑的(de)銅(tong)或表面發(fa)(fa)白的(de)鋁說明已被(bei)氧化(hua)。

第三、在購買電(dian)線時應注意查看質(zhi)(zhi)量合格(ge)證(zheng)書。如果電(dian)線的質(zhi)(zhi)量合格(ge)，那么其電(dian)線質(zhi)(zhi)量應該也受過檢(jian)驗(yan)，不會有太(tai)大(da)的問(wen)題。
