不(bu)合格電線(xian)電纜的(de)危害

電(dian)線電(dian)纜是用于傳輸(shu)電(dian)力(li)、傳輸(shu)信息和實(shi)現電(dian)磁能量轉換的一大(da)類(lei)電(dian)工產品(pin)(pin)。在抽查過程中，發現了大(da)量的不合格(ge)產品(pin)(pin)，這些劣質產品(pin)(pin)給電(dian)力(li)系統正常(chang)運行埋下諸多隱患(huan)。

1、標(biao)志不(bu)合格(ge)的(de)電(dian)(dian)線(xian)電(dian)(dian)纜。標(biao)志是(shi)電(dian)(dian)線(xian)電(dian)(dian)纜使用識別產品(pin)基本信(xin)息(xi)的(de)主要(yao)途徑(jing)，根據標(biao)準規(gui)定標(biao)志的(de)主要(yao)內容是(shi)：產品(pin)型(xing)號(hao)(hao)、規(gui)格(ge)、標(biao)準號(hao)(hao)、廠(chang)名、產地(di)等在(zai)一定的(de)標(biao)示間距內，當標(biao)志不(bu)合格(ge)時，會(hui)造成施工人員識別錯誤，嚴重(zhong)時會(hui)引發電(dian)(dian)氣事故。

2、結構尺(chi)(chi)寸不(bu)合格的電(dian)(dian)線(xian)電(dian)(dian)纜(lan)(lan)。結構尺(chi)(chi)寸的主要問題是護(hu)套厚度(du)，絕(jue)緣(yuan)厚度(du)，當電(dian)(dian)纜(lan)(lan)的護(hu)套和(he)絕(jue)緣(yuan)厚度(du)不(bu)達標時，致(zhi)使電(dian)(dian)線(xian)電(dian)(dian)纜(lan)(lan)耐電(dian)(dian)氣(qi)強度(du)會嚴重降低(di)，導致(zhi)電(dian)(dian)線(xian)電(dian)(dian)纜(lan)(lan)的使用(yong)壽命(ming)縮短，嚴重時可(ke)導致(zhi)電(dian)(dian)線(xian)電(dian)(dian)纜(lan)(lan)被擊穿，絕(jue)緣(yuan)（護(hu)套）層起不(bu)到正常保護(hu)作用(yong)，從(cong)而(er)發生電(dian)(dian)氣(qi)短路和(he)火(huo)災等現(xian)象(xiang)。

3、護(hu)套(tao)式(shi)絕(jue)緣老化前(qian)(qian)的抗(kang)張強度(du)(du)、伸長率合(he)(he)格(ge)(ge)的電(dian)線(xian)(xian)電(dian)纜。絕(jue)緣護(hu)套(tao)老化前(qian)(qian)的抗(kang)張強度(du)(du)、伸長率不合(he)(he)格(ge)(ge)直接大(da)大(da)縮短(duan)電(dian)線(xian)(xian)電(dian)纜的工(gong)作用壽命，而且在施(shi)工(gong)或在長時(shi)間通(tong)電(dian)且溫(wen)度(du)(du)較高(gao)的環境中(zhong)，極易(yi)出現絕(jue)緣體斷裂，致使(shi)帶電(dian)導體裸(luo)露，發生(sheng)能觸電(dian)式(shi)短(duan)路(lu)危險。其不合(he)(he)格(ge)(ge)的主要原因(yin)是使(shi)用了再生(sheng)料生(sheng)產，以降(jiang)低產品成本，二是不具備生(sheng)產資格(ge)(ge)小(xiao)型企業。

4、導體(ti)(ti)電(dian)(dian)阻(zu)不(bu)(bu)合格的(de)(de)(de)電(dian)(dian)線(xian)(xian)。導體(ti)(ti)電(dian)(dian)阻(zu)主要是考(kao)核電(dian)(dian)線(xian)(xian)電(dian)(dian)纜(lan)的(de)(de)(de)導體(ti)(ti)材(cai)料以及截面是否符合的(de)(de)(de)重要指(zhi)標。當導體(ti)(ti)電(dian)(dian)阻(zu)超標時(shi)，就增大了(le)(le)電(dian)(dian)流在(zai)線(xian)(xian)路上通過時(shi)的(de)(de)(de)損耗，加劇(ju)了(le)(le)電(dian)(dian)線(xian)(xian)電(dian)(dian)纜(lan)的(de)(de)(de)發熱。導體(ti)(ti)電(dian)(dian)阻(zu)不(bu)(bu)合格的(de)(de)(de)原(yuan)因，主要進企業為了(le)(le)降低(di)成本(ben)，將占原(yuan)材(cai)料成本(ben)80%的(de)(de)(de)銅(tong)材(cai)縮水，要么降低(di)導體(ti)(ti)的(de)(de)(de)截面積，要么使用含雜(za)質過高(gao)的(de)(de)(de)再(zai)生銅(tong)，這樣致使電(dian)(dian)線(xian)(xian)電(dian)(dian)纜(lan)的(de)(de)(de)導體(ti)(ti)電(dian)(dian)阻(zu)嚴重超標，在(zai)使用過程中除易引發火災，還會加速包(bao)覆在(zai)電(dian)(dian)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(guo)程中，消費者應注意以(yi)下幾個事(shi)

第一、要觀(guan)察電(dian)線(xian)的(de)外觀(guan)。合格產品(pin)的(de)絕(jue)緣（護套(tao)）層柔(rou)軟、有韌(ren)性和伸(shen)縮性、表面層緊密、光(guang)滑、無(wu)粗糙感。如(ru)果包(bao)裹電(dian)線(xian)的(de)塑(su)料很容易被剝去(qu)，則存在塑(su)料強度不夠的(de)問題。

第二(er)、要看電線的(de)截(jie)面(mian)(mian)(mian)(mian)。合格產品的(de)銅芯或(huo)鋁芯表面(mian)(mian)(mian)(mian)應(ying)該具有金屬光澤，表面(mian)(mian)(mian)(mian)發(fa)黑的(de)銅或(huo)表面(mian)(mian)(mian)(mian)發(fa)白的(de)鋁說明已被氧化。

第三、在購買電(dian)(dian)線時應注意查看質(zhi)量(liang)合(he)格證書(shu)。如果(guo)電(dian)(dian)線的質(zhi)量(liang)合(he)格，那么其電(dian)(dian)線質(zhi)量(liang)應該也(ye)受(shou)過(guo)檢驗，不會(hui)有(you)太大的問題(ti)。
