不(bu)合格電線電纜(lan)的危(wei)害(hai)

電(dian)線電(dian)纜是用于傳輸(shu)電(dian)力、傳輸(shu)信息和(he)實現電(dian)磁能量轉換的一大類電(dian)工產(chan)品。在抽查過程(cheng)中，發現了(le)大量的不(bu)合格產(chan)品，這些(xie)劣質產(chan)品給電(dian)力系統正常運行(xing)埋下諸多隱患。

1、標(biao)志不合(he)格(ge)的(de)電(dian)線電(dian)纜(lan)。標(biao)志是電(dian)線電(dian)纜(lan)使(shi)用識別產品基(ji)本信息(xi)的(de)主(zhu)要途徑，根據標(biao)準(zhun)規(gui)定標(biao)志的(de)主(zhu)要內容是：產品型號、規(gui)格(ge)、標(biao)準(zhun)號、廠名、產地等在一定的(de)標(biao)示(shi)間(jian)距內，當標(biao)志不合(he)格(ge)時，會(hui)造成施工(gong)人員識別錯誤，嚴重(zhong)時會(hui)引發電(dian)氣事故。

2、結構尺寸(cun)不合格(ge)的(de)(de)電(dian)(dian)線(xian)(xian)電(dian)(dian)纜(lan)。結構尺寸(cun)的(de)(de)主要問題是護(hu)套厚(hou)度，絕(jue)緣厚(hou)度，當電(dian)(dian)纜(lan)的(de)(de)護(hu)套和絕(jue)緣厚(hou)度不達標(biao)時(shi)，致使電(dian)(dian)線(xian)(xian)電(dian)(dian)纜(lan)耐(nai)電(dian)(dian)氣強度會(hui)嚴重降低，導(dao)致電(dian)(dian)線(xian)(xian)電(dian)(dian)纜(lan)的(de)(de)使用(yong)壽命(ming)縮短(duan)，嚴重時(shi)可導(dao)致電(dian)(dian)線(xian)(xian)電(dian)(dian)纜(lan)被擊(ji)穿，絕(jue)緣（護(hu)套）層起不到(dao)正常保(bao)護(hu)作用(yong)，從而發生電(dian)(dian)氣短(duan)路和火災(zai)等現象。

3、護套式(shi)絕緣(yuan)(yuan)老化前的(de)(de)(de)抗張強度(du)、伸長(chang)率合(he)格(ge)(ge)的(de)(de)(de)電線(xian)電纜(lan)。絕緣(yuan)(yuan)護套老化前的(de)(de)(de)抗張強度(du)、伸長(chang)率不合(he)格(ge)(ge)直(zhi)接大(da)大(da)縮短電線(xian)電纜(lan)的(de)(de)(de)工作用(yong)壽(shou)命(ming)，而且(qie)在施工或在長(chang)時間通電且(qie)溫度(du)較高的(de)(de)(de)環境中，極易出現絕緣(yuan)(yuan)體斷裂，致使(shi)帶電導體裸露(lu)，發生能觸電式(shi)短路危(wei)險。其不合(he)格(ge)(ge)的(de)(de)(de)主要原因(yin)是使(shi)用(yong)了(le)再生料(liao)生產(chan)，以降低產(chan)品(pin)成本，二是不具備生產(chan)資格(ge)(ge)小型企業。

4、導(dao)(dao)體(ti)(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)不合格的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)線。導(dao)(dao)體(ti)(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)主要(yao)是考(kao)核電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)的(de)(de)(de)(de)(de)導(dao)(dao)體(ti)(ti)(ti)材料以及截(jie)面是否符合的(de)(de)(de)(de)(de)重要(yao)指標。當導(dao)(dao)體(ti)(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)超標時，就增大了電(dian)(dian)(dian)(dian)流在(zai)線路上通(tong)過(guo)時的(de)(de)(de)(de)(de)損(sun)耗，加(jia)劇(ju)了電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)的(de)(de)(de)(de)(de)發(fa)熱(re)。導(dao)(dao)體(ti)(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)不合格的(de)(de)(de)(de)(de)原因，主要(yao)進(jin)企(qi)業(ye)為了降(jiang)低成(cheng)(cheng)本，將占原材料成(cheng)(cheng)本80%的(de)(de)(de)(de)(de)銅材縮(suo)水(shui)，要(yao)么降(jiang)低導(dao)(dao)體(ti)(ti)(ti)的(de)(de)(de)(de)(de)截(jie)面積(ji)，要(yao)么使(shi)(shi)用含雜質過(guo)高的(de)(de)(de)(de)(de)再生銅，這樣(yang)致使(shi)(shi)電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜(lan)的(de)(de)(de)(de)(de)導(dao)(dao)體(ti)(ti)(ti)電(dian)(dian)(dian)(dian)阻(zu)嚴重超標，在(zai)使(shi)(shi)用過(guo)程中除易(yi)引發(fa)火災，還會加(jia)速包覆在(zai)電(dian)(dian)(dian)(dian)線外的(de)(de)(de)(de)(de)絕緣層的(de)(de)(de)(de)(de)老化。

在購買(mai)電線電纜的過程中，消費者應注意以下幾個事(shi)

第(di)一、要觀(guan)察電線的外觀(guan)。合格產(chan)品的絕(jue)緣(yuan)（護套）層(ceng)柔軟、有韌性和伸縮(suo)性、表(biao)面層(ceng)緊密(mi)、光滑、無粗糙感。如果包裹電線的塑(su)(su)料很容易(yi)被剝去，則存在塑(su)(su)料強度(du)不夠(gou)的問題。

第二(er)、要看電線的截面(mian)(mian)。合(he)格產品的銅芯或(huo)鋁(lv)芯表面(mian)(mian)應該(gai)具有金屬光澤，表面(mian)(mian)發黑的銅或(huo)表面(mian)(mian)發白的鋁(lv)說(shuo)明已被氧化。

第三、在購買電線時應注意查看質(zhi)量(liang)合(he)格(ge)證書。如果(guo)電線的質(zhi)量(liang)合(he)格(ge)，那么其(qi)電線質(zhi)量(liang)應該(gai)也受過檢驗，不會(hui)有(you)太大(da)的問題。
