不合(he)格電線電纜(lan)的危害

電(dian)線電(dian)纜是用于傳輸電(dian)力(li)、傳輸信息和實現電(dian)磁能量轉換的(de)一大類電(dian)工產品(pin)。在抽查過程中，發現了大量的(de)不合格(ge)產品(pin)，這些(xie)劣質產品(pin)給電(dian)力(li)系統正(zheng)常運行埋下諸多隱患。

1、標(biao)志(zhi)不(bu)合格的(de)電(dian)線(xian)電(dian)纜。標(biao)志(zhi)是電(dian)線(xian)電(dian)纜使用識(shi)(shi)別(bie)產(chan)品基本信息的(de)主要(yao)途徑(jing)，根據(ju)標(biao)準規定標(biao)志(zhi)的(de)主要(yao)內容是：產(chan)品型號、規格、標(biao)準號、廠名、產(chan)地等在一定的(de)標(biao)示間距內，當標(biao)志(zhi)不(bu)合格時，會(hui)(hui)造成施工人員識(shi)(shi)別(bie)錯誤，嚴重時會(hui)(hui)引(yin)發電(dian)氣(qi)事故。

2、結構尺寸不(bu)合格的電(dian)(dian)線(xian)電(dian)(dian)纜。結構尺寸的主要問題是護套(tao)(tao)厚度(du)(du)，絕(jue)緣(yuan)厚度(du)(du)，當電(dian)(dian)纜的護套(tao)(tao)和絕(jue)緣(yuan)厚度(du)(du)不(bu)達標(biao)時(shi)，致使電(dian)(dian)線(xian)電(dian)(dian)纜耐電(dian)(dian)氣強度(du)(du)會嚴(yan)重降(jiang)低，導致電(dian)(dian)線(xian)電(dian)(dian)纜的使用壽(shou)命縮短(duan)，嚴(yan)重時(shi)可導致電(dian)(dian)線(xian)電(dian)(dian)纜被(bei)擊(ji)穿(chuan)，絕(jue)緣(yuan)（護套(tao)(tao)）層起不(bu)到(dao)正常保護作(zuo)用，從而發生電(dian)(dian)氣短(duan)路和火災等現(xian)象。

3、護套式(shi)絕緣(yuan)(yuan)老化(hua)前(qian)的(de)抗張強度(du)(du)、伸長(chang)率合格(ge)(ge)(ge)的(de)電(dian)(dian)線(xian)電(dian)(dian)纜。絕緣(yuan)(yuan)護套老化(hua)前(qian)的(de)抗張強度(du)(du)、伸長(chang)率不合格(ge)(ge)(ge)直接大大縮短電(dian)(dian)線(xian)電(dian)(dian)纜的(de)工作用(yong)壽命，而且(qie)在施(shi)工或在長(chang)時間通電(dian)(dian)且(qie)溫(wen)度(du)(du)較(jiao)高(gao)的(de)環境中(zhong)，極易出現絕緣(yuan)(yuan)體斷裂，致使(shi)帶(dai)電(dian)(dian)導體裸露，發生(sheng)(sheng)(sheng)能觸電(dian)(dian)式(shi)短路(lu)危險。其不合格(ge)(ge)(ge)的(de)主(zhu)要原(yuan)因是使(shi)用(yong)了再生(sheng)(sheng)(sheng)料生(sheng)(sheng)(sheng)產，以降低產品成本，二是不具備生(sheng)(sheng)(sheng)產資(zi)格(ge)(ge)(ge)小(xiao)型企業。

4、導(dao)(dao)(dao)體(ti)(ti)電(dian)阻不合格的(de)(de)(de)(de)(de)(de)電(dian)線。導(dao)(dao)(dao)體(ti)(ti)電(dian)阻主要(yao)是考(kao)核電(dian)線電(dian)纜的(de)(de)(de)(de)(de)(de)導(dao)(dao)(dao)體(ti)(ti)材(cai)料以(yi)及截(jie)面是否符合的(de)(de)(de)(de)(de)(de)重要(yao)指標(biao)。當導(dao)(dao)(dao)體(ti)(ti)電(dian)阻超標(biao)時，就增大了(le)電(dian)流在(zai)(zai)線路上(shang)通過時的(de)(de)(de)(de)(de)(de)損耗，加(jia)劇了(le)電(dian)線電(dian)纜的(de)(de)(de)(de)(de)(de)發熱(re)。導(dao)(dao)(dao)體(ti)(ti)電(dian)阻不合格的(de)(de)(de)(de)(de)(de)原(yuan)(yuan)因(yin)，主要(yao)進(jin)企業為(wei)了(le)降(jiang)低成(cheng)本，將(jiang)占原(yuan)(yuan)材(cai)料成(cheng)本80%的(de)(de)(de)(de)(de)(de)銅材(cai)縮水，要(yao)么(me)降(jiang)低導(dao)(dao)(dao)體(ti)(ti)的(de)(de)(de)(de)(de)(de)截(jie)面積，要(yao)么(me)使用(yong)含雜質(zhi)過高的(de)(de)(de)(de)(de)(de)再生銅，這樣(yang)致使電(dian)線電(dian)纜的(de)(de)(de)(de)(de)(de)導(dao)(dao)(dao)體(ti)(ti)電(dian)阻嚴重超標(biao)，在(zai)(zai)使用(yong)過程(cheng)中除(chu)易引(yin)發火災(zai)，還會加(jia)速包覆(fu)在(zai)(zai)電(dian)線外的(de)(de)(de)(de)(de)(de)絕緣層的(de)(de)(de)(de)(de)(de)老化。

在購買電線電纜(lan)的(de)過程中，消費(fei)者應(ying)注意以下幾(ji)個事

第一、要觀察電(dian)線(xian)的(de)外觀。合格產品的(de)絕(jue)緣(yuan)（護套）層(ceng)柔(rou)軟、有韌性和伸縮性、表(biao)面(mian)層(ceng)緊密(mi)、光(guang)滑(hua)、無粗糙感(gan)。如果包裹電(dian)線(xian)的(de)塑料很容易(yi)被(bei)剝去(qu)，則存(cun)在塑料強度不夠(gou)的(de)問題。

第二、要看電(dian)線(xian)的(de)截面(mian)(mian)。合格產品的(de)銅芯或鋁芯表面(mian)(mian)應該具有金屬光澤，表面(mian)(mian)發(fa)黑的(de)銅或表面(mian)(mian)發(fa)白的(de)鋁說明已被(bei)氧化。

第三(san)、在購(gou)買電(dian)線時(shi)應注(zhu)意查看質量合格(ge)證書。如果電(dian)線的(de)(de)質量合格(ge)，那么其電(dian)線質量應該也受過檢驗，不會有太大的(de)(de)問題。
