不合格電線(xian)電纜的危害

電線電纜是用于傳(chuan)輸(shu)電力、傳(chuan)輸(shu)信息和實(shi)現(xian)電磁(ci)能量轉換的(de)一(yi)大類電工產(chan)品。在抽查過(guo)程(cheng)中(zhong)，發現(xian)了(le)大量的(de)不合格產(chan)品，這(zhe)些劣質產(chan)品給電力系統正常運行埋(mai)下諸多隱患。

1、標(biao)(biao)志(zhi)不(bu)合格(ge)的(de)電(dian)(dian)線電(dian)(dian)纜。標(biao)(biao)志(zhi)是電(dian)(dian)線電(dian)(dian)纜使(shi)用識(shi)別(bie)產(chan)品(pin)基(ji)本(ben)信(xin)息的(de)主(zhu)要(yao)途徑(jing)，根據(ju)標(biao)(biao)準規(gui)(gui)定(ding)標(biao)(biao)志(zhi)的(de)主(zhu)要(yao)內容是：產(chan)品(pin)型號(hao)、規(gui)(gui)格(ge)、標(biao)(biao)準號(hao)、廠名、產(chan)地(di)等在一定(ding)的(de)標(biao)(biao)示間(jian)距內，當標(biao)(biao)志(zhi)不(bu)合格(ge)時，會(hui)造成(cheng)施工(gong)人員識(shi)別(bie)錯誤，嚴重時會(hui)引發電(dian)(dian)氣事故。

2、結構尺(chi)寸(cun)(cun)不合格(ge)的電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)。結構尺(chi)寸(cun)(cun)的主要問題是護(hu)套厚度，絕(jue)緣厚度，當電(dian)(dian)(dian)纜(lan)的護(hu)套和(he)絕(jue)緣厚度不達(da)標時(shi)，致使(shi)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)耐(nai)電(dian)(dian)(dian)氣(qi)(qi)強度會嚴重降(jiang)低，導(dao)致電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)的使(shi)用壽(shou)命(ming)縮短(duan)，嚴重時(shi)可導(dao)致電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)被擊穿(chuan)，絕(jue)緣（護(hu)套）層起不到正常保護(hu)作用，從而發生電(dian)(dian)(dian)氣(qi)(qi)短(duan)路和(he)火災等現象。

3、護(hu)套式絕緣老化前的(de)(de)抗張強(qiang)度、伸(shen)長(chang)率合(he)格(ge)(ge)的(de)(de)電線電纜。絕緣護(hu)套老化前的(de)(de)抗張強(qiang)度、伸(shen)長(chang)率不合(he)格(ge)(ge)直接大大縮短(duan)電線電纜的(de)(de)工作用壽(shou)命，而且(qie)在施工或(huo)在長(chang)時間通電且(qie)溫度較高的(de)(de)環境中，極(ji)易出現絕緣體斷裂，致使(shi)帶電導體裸(luo)露，發生(sheng)能觸(chu)電式短(duan)路危險。其不合(he)格(ge)(ge)的(de)(de)主要原因(yin)是使(shi)用了再(zai)生(sheng)料(liao)生(sheng)產(chan)，以(yi)降低產(chan)品(pin)成本，二是不具備生(sheng)產(chan)資(zi)格(ge)(ge)小型(xing)企業。

4、導(dao)體(ti)電(dian)(dian)(dian)阻(zu)不(bu)(bu)合(he)(he)格的(de)電(dian)(dian)(dian)線(xian)(xian)。導(dao)體(ti)電(dian)(dian)(dian)阻(zu)主要是考(kao)核電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)的(de)導(dao)體(ti)材(cai)(cai)料(liao)以及截(jie)面是否符合(he)(he)的(de)重要指標。當導(dao)體(ti)電(dian)(dian)(dian)阻(zu)超(chao)標時，就增(zeng)大了電(dian)(dian)(dian)流在(zai)線(xian)(xian)路上通過時的(de)損耗(hao)，加劇了電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)的(de)發熱。導(dao)體(ti)電(dian)(dian)(dian)阻(zu)不(bu)(bu)合(he)(he)格的(de)原(yuan)因，主要進企業(ye)為了降低(di)成本，將占(zhan)原(yuan)材(cai)(cai)料(liao)成本80%的(de)銅材(cai)(cai)縮(suo)水，要么降低(di)導(dao)體(ti)的(de)截(jie)面積，要么使用含雜(za)質過高的(de)再生銅，這(zhe)樣致使電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)的(de)導(dao)體(ti)電(dian)(dian)(dian)阻(zu)嚴重超(chao)標，在(zai)使用過程中(zhong)除易引發火災，還會(hui)加速包覆(fu)在(zai)電(dian)(dian)(dian)線(xian)(xian)外的(de)絕緣層的(de)老化(hua)。

在購買電(dian)線電(dian)纜的過(guo)程中，消費者(zhe)應(ying)注意以下(xia)幾個事

第(di)一、要觀(guan)察電(dian)線的(de)外觀(guan)。合格(ge)產品的(de)絕緣（護套）層(ceng)柔軟、有韌性和伸(shen)縮性、表(biao)面層(ceng)緊密、光滑、無粗糙感。如果包裹電(dian)線的(de)塑料很容易被剝去(qu)，則存在塑料強度(du)不夠的(de)問題(ti)。

第(di)二、要看電線的(de)(de)截面。合格(ge)產品的(de)(de)銅芯(xin)或鋁(lv)芯(xin)表(biao)面應該具有金屬光澤(ze)，表(biao)面發(fa)(fa)黑的(de)(de)銅或表(biao)面發(fa)(fa)白(bai)的(de)(de)鋁(lv)說明已被氧化。

第三、在購買電(dian)線(xian)時應(ying)注意(yi)查(cha)看質(zhi)(zhi)量(liang)合格(ge)證書。如(ru)果電(dian)線(xian)的(de)質(zhi)(zhi)量(liang)合格(ge)，那么其電(dian)線(xian)質(zhi)(zhi)量(liang)應(ying)該也受(shou)過檢驗，不會有太大的(de)問題。
