不合(he)格電線電纜的危害

電(dian)線電(dian)纜(lan)是用(yong)于傳輸電(dian)力、傳輸信(xin)息和實現電(dian)磁(ci)能(neng)量轉換的一大(da)(da)類電(dian)工(gong)產品。在抽查(cha)過程(cheng)中，發(fa)現了大(da)(da)量的不合格(ge)產品，這些劣質產品給電(dian)力系統正常運行埋下諸多(duo)隱患。

1、標(biao)志(zhi)不合(he)格的(de)電(dian)線(xian)電(dian)纜(lan)。標(biao)志(zhi)是電(dian)線(xian)電(dian)纜(lan)使用識別(bie)產品(pin)基本信息的(de)主(zhu)要(yao)途徑(jing)，根據標(biao)準規(gui)定(ding)標(biao)志(zhi)的(de)主(zhu)要(yao)內(nei)容是：產品(pin)型號(hao)、規(gui)格、標(biao)準號(hao)、廠(chang)名、產地等在(zai)一定(ding)的(de)標(biao)示(shi)間(jian)距內(nei)，當(dang)標(biao)志(zhi)不合(he)格時，會(hui)造(zao)成施(shi)工(gong)人(ren)員識別(bie)錯誤，嚴重時會(hui)引發(fa)電(dian)氣事故。

2、結構(gou)尺寸不合格的(de)電(dian)(dian)線(xian)電(dian)(dian)纜(lan)。結構(gou)尺寸的(de)主要問題是護(hu)套厚度(du)，絕緣厚度(du)，當電(dian)(dian)纜(lan)的(de)護(hu)套和絕緣厚度(du)不達標時，致(zhi)使電(dian)(dian)線(xian)電(dian)(dian)纜(lan)耐電(dian)(dian)氣強(qiang)度(du)會嚴(yan)(yan)重(zhong)降低，導致(zhi)電(dian)(dian)線(xian)電(dian)(dian)纜(lan)的(de)使用壽命縮短(duan)，嚴(yan)(yan)重(zhong)時可導致(zhi)電(dian)(dian)線(xian)電(dian)(dian)纜(lan)被擊穿，絕緣（護(hu)套）層起不到正(zheng)常保護(hu)作(zuo)用，從(cong)而發生電(dian)(dian)氣短(duan)路(lu)和火災(zai)等(deng)現象。

3、護(hu)套式(shi)絕(jue)緣老(lao)(lao)化前(qian)的(de)(de)抗張(zhang)強度(du)(du)、伸長(chang)率合格的(de)(de)電(dian)(dian)線(xian)電(dian)(dian)纜。絕(jue)緣護(hu)套老(lao)(lao)化前(qian)的(de)(de)抗張(zhang)強度(du)(du)、伸長(chang)率不(bu)合格直接大大縮短電(dian)(dian)線(xian)電(dian)(dian)纜的(de)(de)工作用壽命，而(er)且在施工或在長(chang)時間通電(dian)(dian)且溫度(du)(du)較(jiao)高的(de)(de)環境(jing)中，極易出(chu)現絕(jue)緣體斷裂(lie)，致使帶電(dian)(dian)導體裸露，發(fa)生(sheng)能(neng)觸電(dian)(dian)式(shi)短路危險。其不(bu)合格的(de)(de)主要原(yuan)因(yin)是使用了再生(sheng)料生(sheng)產(chan)(chan)，以降低產(chan)(chan)品成本，二是不(bu)具備生(sheng)產(chan)(chan)資格小型(xing)企業。

4、導(dao)(dao)體電(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)不合(he)格(ge)的(de)(de)電(dian)(dian)(dian)(dian)線。導(dao)(dao)體電(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)主要(yao)是考核電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜的(de)(de)導(dao)(dao)體材(cai)料以(yi)及截(jie)面是否符合(he)的(de)(de)重要(yao)指(zhi)標。當導(dao)(dao)體電(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)超標時(shi)，就增大了電(dian)(dian)(dian)(dian)流在(zai)(zai)線路(lu)上通(tong)過(guo)時(shi)的(de)(de)損耗，加劇了電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜的(de)(de)發熱(re)。導(dao)(dao)體電(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)不合(he)格(ge)的(de)(de)原(yuan)因，主要(yao)進企(qi)業為了降低成本(ben)，將占原(yuan)材(cai)料成本(ben)80%的(de)(de)銅(tong)材(cai)縮水，要(yao)么降低導(dao)(dao)體的(de)(de)截(jie)面積，要(yao)么使用含雜(za)質過(guo)高的(de)(de)再生銅(tong)，這樣致使電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜的(de)(de)導(dao)(dao)體電(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)嚴重超標，在(zai)(zai)使用過(guo)程中除易引(yin)發火災，還會加速包覆在(zai)(zai)電(dian)(dian)(dian)(dian)線外的(de)(de)絕緣層(ceng)的(de)(de)老化。

在購買電線電纜的過(guo)程中，消(xiao)費者應注意以下幾個事

第一、要觀(guan)察(cha)電(dian)線(xian)的(de)外觀(guan)。合(he)格產品(pin)的(de)絕緣（護套）層柔軟、有韌(ren)性和(he)伸縮(suo)性、表面層緊密(mi)、光滑、無粗糙感。如果包裹(guo)電(dian)線(xian)的(de)塑料很容易被(bei)剝去，則存在塑料強度不夠的(de)問題。

第二、要看(kan)電線的截面。合格產品的銅芯(xin)(xin)或(huo)鋁芯(xin)(xin)表面應該具有(you)金屬光(guang)澤，表面發黑(hei)的銅或(huo)表面發白(bai)的鋁說明(ming)已被氧(yang)化。

第三、在購買電(dian)線(xian)時(shi)應注意查(cha)看質量合(he)格證(zheng)書(shu)。如果(guo)電(dian)線(xian)的(de)質量合(he)格，那么其電(dian)線(xian)質量應該也受過檢驗，不會(hui)有太大的(de)問題。
