不合(he)格電線電纜(lan)的(de)危害

電(dian)線電(dian)纜是用于傳輸電(dian)力(li)、傳輸信息和實(shi)現(xian)電(dian)磁能量轉換的一大(da)類電(dian)工(gong)產(chan)(chan)品(pin)。在抽查過(guo)程(cheng)中，發現(xian)了大(da)量的不合格產(chan)(chan)品(pin)，這些劣質產(chan)(chan)品(pin)給電(dian)力(li)系統正(zheng)常運行埋下諸多隱患(huan)。

1、標志(zhi)不(bu)合格的(de)(de)電(dian)(dian)線電(dian)(dian)纜。標志(zhi)是電(dian)(dian)線電(dian)(dian)纜使(shi)用識別產品(pin)基(ji)本信息的(de)(de)主(zhu)(zhu)要途徑，根據標準規(gui)定(ding)標志(zhi)的(de)(de)主(zhu)(zhu)要內容是：產品(pin)型(xing)號(hao)、規(gui)格、標準號(hao)、廠名、產地等(deng)在(zai)一定(ding)的(de)(de)標示間距內，當標志(zhi)不(bu)合格時(shi)，會(hui)(hui)造成(cheng)施工(gong)人員識別錯誤(wu)，嚴重時(shi)會(hui)(hui)引發電(dian)(dian)氣事故。

2、結構(gou)尺寸不(bu)合格的電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)。結構(gou)尺寸的主要問題是護(hu)(hu)套(tao)厚(hou)度，絕緣厚(hou)度，當電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)的護(hu)(hu)套(tao)和(he)絕緣厚(hou)度不(bu)達標時(shi)，致使電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)耐(nai)電(dian)(dian)(dian)(dian)氣(qi)強(qiang)度會嚴重降低，導致電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)的使用(yong)壽命縮短，嚴重時(shi)可導致電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)被擊(ji)穿，絕緣（護(hu)(hu)套(tao)）層起不(bu)到(dao)正(zheng)常保護(hu)(hu)作用(yong)，從而發生(sheng)電(dian)(dian)(dian)(dian)氣(qi)短路和(he)火災等(deng)現象。

3、護套(tao)式絕緣老(lao)化前的抗張(zhang)強(qiang)度(du)、伸長率合(he)(he)格的電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)。絕緣護套(tao)老(lao)化前的抗張(zhang)強(qiang)度(du)、伸長率不(bu)合(he)(he)格直(zhi)接(jie)大大縮短電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)的工作用壽命，而且在施工或在長時間通電(dian)(dian)(dian)且溫度(du)較(jiao)高的環境中，極易出現絕緣體(ti)斷(duan)裂，致使帶電(dian)(dian)(dian)導體(ti)裸露，發生(sheng)能觸電(dian)(dian)(dian)式短路危險。其(qi)不(bu)合(he)(he)格的主要原因(yin)是使用了再生(sheng)料生(sheng)產(chan)，以(yi)降低(di)產(chan)品成本，二(er)是不(bu)具(ju)備生(sheng)產(chan)資格小型企業。

4、導(dao)(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)阻不合格(ge)的(de)(de)(de)電(dian)(dian)(dian)(dian)線(xian)。導(dao)(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)阻主要是考(kao)核電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜的(de)(de)(de)導(dao)(dao)(dao)體(ti)(ti)材(cai)料以及截(jie)面(mian)是否符合的(de)(de)(de)重要指標(biao)(biao)。當導(dao)(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)阻超標(biao)(biao)時，就增大了電(dian)(dian)(dian)(dian)流(liu)在(zai)(zai)線(xian)路上通(tong)過時的(de)(de)(de)損(sun)耗，加(jia)劇了電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜的(de)(de)(de)發熱。導(dao)(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)阻不合格(ge)的(de)(de)(de)原因，主要進企業為了降(jiang)低成本，將占原材(cai)料成本80%的(de)(de)(de)銅(tong)材(cai)縮水，要么降(jiang)低導(dao)(dao)(dao)體(ti)(ti)的(de)(de)(de)截(jie)面(mian)積，要么使用含雜質過高的(de)(de)(de)再生(sheng)銅(tong)，這樣(yang)致使電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜的(de)(de)(de)導(dao)(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)(dian)阻嚴重超標(biao)(biao)，在(zai)(zai)使用過程中除易引發火(huo)災，還會(hui)加(jia)速(su)包覆在(zai)(zai)電(dian)(dian)(dian)(dian)線(xian)外的(de)(de)(de)絕緣層(ceng)的(de)(de)(de)老化(hua)。

在購買電線電纜的過(guo)程中，消(xiao)費者(zhe)應(ying)注意(yi)以下幾個事(shi)

第一、要(yao)觀察電線(xian)的(de)外觀。合格產品的(de)絕(jue)緣（護套）層柔軟、有(you)韌性和(he)伸(shen)縮(suo)性、表面層緊密、光滑、無粗糙感(gan)。如果(guo)包裹電線(xian)的(de)塑料很(hen)容易被剝去，則存在(zai)塑料強度不夠的(de)問題。

第二、要看電線的截(jie)面。合格產(chan)品的銅芯(xin)或鋁芯(xin)表面應該(gai)具有金屬光澤，表面發黑的銅或表面發白(bai)的鋁說(shuo)明已被氧化。

第三、在購買(mai)電線(xian)(xian)時應注意查(cha)看(kan)質(zhi)量合格證書。如果電線(xian)(xian)的(de)質(zhi)量合格，那么其電線(xian)(xian)質(zhi)量應該也受過檢驗，不(bu)會(hui)有太(tai)大的(de)問(wen)題。
