不合格電(dian)線電(dian)纜的危害

電線電纜是用于傳輸(shu)(shu)電力、傳輸(shu)(shu)信息和(he)實現電磁(ci)能(neng)量轉換的一大類電工(gong)產品(pin)。在抽查過(guo)程中，發現了大量的不(bu)合格(ge)產品(pin)，這些劣質產品(pin)給電力系統正常運(yun)行埋下諸多隱(yin)患。

1、標志(zhi)不(bu)合(he)(he)格的(de)(de)電線(xian)電纜。標志(zhi)是電線(xian)電纜使用識別(bie)產品(pin)基本信息的(de)(de)主(zhu)要(yao)途徑，根據標準(zhun)規定(ding)標志(zhi)的(de)(de)主(zhu)要(yao)內(nei)容是：產品(pin)型號(hao)、規格、標準(zhun)號(hao)、廠名、產地等(deng)在一定(ding)的(de)(de)標示間(jian)距內(nei)，當標志(zhi)不(bu)合(he)(he)格時(shi)，會造成施工人員(yuan)識別(bie)錯誤，嚴重時(shi)會引(yin)發電氣事故(gu)。

2、結(jie)構尺寸不合格的(de)電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)。結(jie)構尺寸的(de)主要問題是護(hu)(hu)套(tao)厚度，絕(jue)緣(yuan)厚度，當電(dian)(dian)(dian)纜(lan)的(de)護(hu)(hu)套(tao)和(he)(he)絕(jue)緣(yuan)厚度不達(da)標時，致使電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)耐(nai)電(dian)(dian)(dian)氣(qi)強(qiang)度會嚴(yan)(yan)重(zhong)降低(di)，導致電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)的(de)使用壽命縮短，嚴(yan)(yan)重(zhong)時可(ke)導致電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)被擊穿，絕(jue)緣(yuan)（護(hu)(hu)套(tao)）層起(qi)不到正常保護(hu)(hu)作用，從而發生電(dian)(dian)(dian)氣(qi)短路和(he)(he)火災等(deng)現象(xiang)。

3、護套(tao)式(shi)絕(jue)緣老化前(qian)的(de)(de)抗張強度、伸(shen)長(chang)(chang)率合(he)(he)格的(de)(de)電(dian)(dian)線電(dian)(dian)纜(lan)。絕(jue)緣護套(tao)老化前(qian)的(de)(de)抗張強度、伸(shen)長(chang)(chang)率不合(he)(he)格直(zhi)接(jie)大大縮短電(dian)(dian)線電(dian)(dian)纜(lan)的(de)(de)工作用(yong)壽命，而且在施(shi)工或在長(chang)(chang)時(shi)間通(tong)電(dian)(dian)且溫度較(jiao)高(gao)的(de)(de)環境中(zhong)，極易出現絕(jue)緣體斷裂，致使(shi)帶電(dian)(dian)導(dao)體裸露，發生(sheng)能觸電(dian)(dian)式(shi)短路危險。其(qi)不合(he)(he)格的(de)(de)主要原因(yin)是使(shi)用(yong)了再生(sheng)料生(sheng)產，以降低產品成本，二(er)是不具備生(sheng)產資(zi)格小(xiao)型企業。

4、導(dao)體電(dian)(dian)阻(zu)不合(he)格的(de)(de)(de)電(dian)(dian)線(xian)。導(dao)體電(dian)(dian)阻(zu)主要是考核電(dian)(dian)線(xian)電(dian)(dian)纜(lan)的(de)(de)(de)導(dao)體材料(liao)以及截(jie)面(mian)是否符合(he)的(de)(de)(de)重要指(zhi)標(biao)。當導(dao)體電(dian)(dian)阻(zu)超標(biao)時(shi)，就增大(da)了電(dian)(dian)流在線(xian)路上通過(guo)時(shi)的(de)(de)(de)損(sun)耗，加(jia)劇了電(dian)(dian)線(xian)電(dian)(dian)纜(lan)的(de)(de)(de)發熱。導(dao)體電(dian)(dian)阻(zu)不合(he)格的(de)(de)(de)原(yuan)因，主要進(jin)企業為了降低成(cheng)本，將(jiang)占原(yuan)材料(liao)成(cheng)本80%的(de)(de)(de)銅材縮(suo)水，要么降低導(dao)體的(de)(de)(de)截(jie)面(mian)積，要么使(shi)用含雜質過(guo)高的(de)(de)(de)再生銅，這(zhe)樣致使(shi)電(dian)(dian)線(xian)電(dian)(dian)纜(lan)的(de)(de)(de)導(dao)體電(dian)(dian)阻(zu)嚴(yan)重超標(biao)，在使(shi)用過(guo)程中除易引發火災，還會加(jia)速包覆(fu)在電(dian)(dian)線(xian)外的(de)(de)(de)絕緣層的(de)(de)(de)老化(hua)。

在(zai)購(gou)買電線電纜的過程中，消(xiao)費者應注意以下幾個事

第一、要(yao)觀(guan)察電(dian)線(xian)(xian)的(de)(de)外觀(guan)。合(he)格產品的(de)(de)絕緣（護套）層(ceng)(ceng)柔軟(ruan)、有韌性和伸(shen)縮性、表面層(ceng)(ceng)緊密、光(guang)滑、無(wu)粗(cu)糙感。如果包裹電(dian)線(xian)(xian)的(de)(de)塑料(liao)很容易被剝去，則存在塑料(liao)強度不夠的(de)(de)問題。

第二、要看電線的(de)截面。合格產(chan)品的(de)銅(tong)芯(xin)(xin)或鋁芯(xin)(xin)表面應該具有金屬光澤，表面發黑的(de)銅(tong)或表面發白的(de)鋁說明已被氧化。

第(di)三、在購買(mai)電線時應(ying)注意查看質(zhi)(zhi)量合(he)格證書。如果電線的質(zhi)(zhi)量合(he)格，那么(me)其電線質(zhi)(zhi)量應(ying)該也受過檢(jian)驗，不會有太(tai)大(da)的問題。
