不合(he)格電(dian)線電(dian)纜的(de)危害

電(dian)(dian)線電(dian)(dian)纜是(shi)用于(yu)傳輸電(dian)(dian)力、傳輸信息和實現電(dian)(dian)磁能量轉(zhuan)換的一大類電(dian)(dian)工產(chan)品。在抽查(cha)過程中(zhong)，發(fa)現了(le)大量的不合格產(chan)品，這(zhe)些(xie)劣(lie)質產(chan)品給電(dian)(dian)力系統正常運行埋下諸多(duo)隱患。

1、標(biao)志(zhi)(zhi)不(bu)(bu)合格(ge)的電(dian)(dian)線(xian)電(dian)(dian)纜(lan)。標(biao)志(zhi)(zhi)是電(dian)(dian)線(xian)電(dian)(dian)纜(lan)使(shi)用識(shi)別產(chan)品(pin)基本(ben)信(xin)息的主(zhu)(zhu)要途(tu)徑，根據(ju)標(biao)準規(gui)定(ding)標(biao)志(zhi)(zhi)的主(zhu)(zhu)要內(nei)(nei)容(rong)是：產(chan)品(pin)型(xing)號、規(gui)格(ge)、標(biao)準號、廠名、產(chan)地等在一定(ding)的標(biao)示間(jian)距內(nei)(nei)，當標(biao)志(zhi)(zhi)不(bu)(bu)合格(ge)時(shi)，會(hui)造成施工人員識(shi)別錯誤，嚴重時(shi)會(hui)引(yin)發(fa)電(dian)(dian)氣事(shi)故。

2、結(jie)構尺(chi)寸不合格的電(dian)線電(dian)纜。結(jie)構尺(chi)寸的主要問題是(shi)護套厚度(du)，絕(jue)緣厚度(du)，當電(dian)纜的護套和(he)絕(jue)緣厚度(du)不達標時，致使電(dian)線電(dian)纜耐(nai)電(dian)氣強(qiang)度(du)會(hui)嚴(yan)重降(jiang)低(di)，導(dao)致電(dian)線電(dian)纜的使用壽命縮(suo)短，嚴(yan)重時可導(dao)致電(dian)線電(dian)纜被擊穿，絕(jue)緣（護套）層(ceng)起不到正常保護作(zuo)用，從(cong)而發(fa)生電(dian)氣短路和(he)火災等現象。

3、護套式絕緣(yuan)老化前(qian)的(de)抗張強度、伸(shen)長(chang)率合格的(de)電(dian)(dian)線電(dian)(dian)纜。絕緣(yuan)護套老化前(qian)的(de)抗張強度、伸(shen)長(chang)率不合格直接(jie)大(da)大(da)縮短電(dian)(dian)線電(dian)(dian)纜的(de)工作用壽命，而且在施工或在長(chang)時(shi)間通電(dian)(dian)且溫(wen)度較高的(de)環(huan)境中(zhong)，極易出現絕緣(yuan)體斷裂，致使帶(dai)電(dian)(dian)導體裸露(lu)，發生(sheng)能觸電(dian)(dian)式短路危險(xian)。其不合格的(de)主(zhu)要原因是使用了再(zai)生(sheng)料生(sheng)產(chan)，以(yi)降低產(chan)品成本，二是不具備生(sheng)產(chan)資(zi)格小型企業。

4、導(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)阻(zu)不(bu)合格的(de)(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)線(xian)。導(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)阻(zu)主要(yao)是考(kao)核電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)的(de)(de)(de)(de)(de)(de)(de)導(dao)(dao)體(ti)(ti)材(cai)料(liao)以及截(jie)面是否符合的(de)(de)(de)(de)(de)(de)(de)重要(yao)指標(biao)(biao)。當導(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)阻(zu)超標(biao)(biao)時(shi)，就增大(da)了電(dian)(dian)(dian)流在(zai)線(xian)路上通過時(shi)的(de)(de)(de)(de)(de)(de)(de)損耗，加劇了電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)的(de)(de)(de)(de)(de)(de)(de)發(fa)熱。導(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)阻(zu)不(bu)合格的(de)(de)(de)(de)(de)(de)(de)原因，主要(yao)進企業(ye)為了降(jiang)低成(cheng)本，將(jiang)占原材(cai)料(liao)成(cheng)本80%的(de)(de)(de)(de)(de)(de)(de)銅材(cai)縮水(shui)，要(yao)么降(jiang)低導(dao)(dao)體(ti)(ti)的(de)(de)(de)(de)(de)(de)(de)截(jie)面積，要(yao)么使用(yong)含雜質過高的(de)(de)(de)(de)(de)(de)(de)再生銅，這樣致(zhi)使電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)的(de)(de)(de)(de)(de)(de)(de)導(dao)(dao)體(ti)(ti)電(dian)(dian)(dian)阻(zu)嚴重超標(biao)(biao)，在(zai)使用(yong)過程中除易(yi)引發(fa)火災，還會加速包覆(fu)在(zai)電(dian)(dian)(dian)線(xian)外的(de)(de)(de)(de)(de)(de)(de)絕緣(yuan)層的(de)(de)(de)(de)(de)(de)(de)老化。

在購買電線電纜的過程(cheng)中(zhong)，消費者應注意以下幾個事

第(di)一、要觀察(cha)電線(xian)的外(wai)觀。合(he)格產品的絕緣（護套）層(ceng)(ceng)柔(rou)軟(ruan)、有韌性和伸(shen)縮性、表面層(ceng)(ceng)緊密(mi)、光滑(hua)、無粗糙感。如果(guo)包裹(guo)電線(xian)的塑料很容易被剝去(qu)，則存在塑料強度不夠(gou)的問題。

第二、要看電線的截面(mian)。合格產品(pin)的銅(tong)芯(xin)或(huo)鋁芯(xin)表面(mian)應該具有金屬光澤，表面(mian)發黑的銅(tong)或(huo)表面(mian)發白(bai)的鋁說明(ming)已被氧化。

第三、在購買電(dian)(dian)線時(shi)應注(zhu)意查看質量合格(ge)(ge)證書(shu)。如果電(dian)(dian)線的(de)質量合格(ge)(ge)，那(nei)么其(qi)電(dian)(dian)線質量應該也(ye)受過檢驗，不(bu)會有太大的(de)問題(ti)。
