不(bu)合格電線(xian)電纜的(de)危害

電線電纜是用于(yu)傳(chuan)(chuan)輸(shu)(shu)電力(li)、傳(chuan)(chuan)輸(shu)(shu)信(xin)息和實現(xian)(xian)電磁能量(liang)轉換(huan)的一大(da)類電工(gong)產品(pin)。在抽(chou)查過程中，發現(xian)(xian)了大(da)量(liang)的不合格產品(pin)，這些劣質產品(pin)給(gei)電力(li)系統正常運行(xing)埋下諸多隱患。

1、標(biao)(biao)志(zhi)(zhi)(zhi)不(bu)合格(ge)的電(dian)(dian)線(xian)電(dian)(dian)纜(lan)。標(biao)(biao)志(zhi)(zhi)(zhi)是電(dian)(dian)線(xian)電(dian)(dian)纜(lan)使用識(shi)別產(chan)(chan)品(pin)基本信息的主(zhu)要(yao)(yao)途徑，根據標(biao)(biao)準(zhun)規定標(biao)(biao)志(zhi)(zhi)(zhi)的主(zhu)要(yao)(yao)內容是：產(chan)(chan)品(pin)型(xing)號、規格(ge)、標(biao)(biao)準(zhun)號、廠名、產(chan)(chan)地等(deng)在一(yi)定的標(biao)(biao)示(shi)間距內，當(dang)標(biao)(biao)志(zhi)(zhi)(zhi)不(bu)合格(ge)時，會(hui)造成施工人員(yuan)識(shi)別錯(cuo)誤(wu)，嚴重(zhong)時會(hui)引發電(dian)(dian)氣事故。

2、結(jie)構尺(chi)寸(cun)不合格(ge)的(de)(de)(de)電(dian)線電(dian)纜。結(jie)構尺(chi)寸(cun)的(de)(de)(de)主要問(wen)題(ti)是護(hu)套厚(hou)度(du)，絕緣(yuan)厚(hou)度(du)，當電(dian)纜的(de)(de)(de)護(hu)套和(he)絕緣(yuan)厚(hou)度(du)不達標(biao)時(shi)(shi)，致使(shi)電(dian)線電(dian)纜耐電(dian)氣強度(du)會嚴(yan)(yan)重降低，導致電(dian)線電(dian)纜的(de)(de)(de)使(shi)用壽命縮短，嚴(yan)(yan)重時(shi)(shi)可導致電(dian)線電(dian)纜被擊穿，絕緣(yuan)（護(hu)套）層起不到正(zheng)常保護(hu)作用，從(cong)而發生電(dian)氣短路(lu)和(he)火(huo)災等現象。

3、護套式絕(jue)緣(yuan)(yuan)老(lao)化前(qian)的(de)抗張強度(du)、伸(shen)長(chang)率合格(ge)(ge)(ge)的(de)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜。絕(jue)緣(yuan)(yuan)護套老(lao)化前(qian)的(de)抗張強度(du)、伸(shen)長(chang)率不合格(ge)(ge)(ge)直接大大縮短(duan)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜的(de)工作(zuo)用(yong)壽命(ming)，而且在施工或在長(chang)時(shi)間通電(dian)(dian)(dian)且溫(wen)度(du)較(jiao)高的(de)環境中，極易出現絕(jue)緣(yuan)(yuan)體斷裂，致使帶(dai)電(dian)(dian)(dian)導體裸露(lu)，發生(sheng)能觸電(dian)(dian)(dian)式短(duan)路(lu)危險。其不合格(ge)(ge)(ge)的(de)主要(yao)原(yuan)因是(shi)使用(yong)了再生(sheng)料生(sheng)產，以降低(di)產品成本，二(er)是(shi)不具備(bei)生(sheng)產資格(ge)(ge)(ge)小(xiao)型企(qi)業。

4、導(dao)(dao)體(ti)電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)(zu)不合(he)格的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)線。導(dao)(dao)體(ti)電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)(zu)主要(yao)是(shi)考核(he)電(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)纜的(de)(de)(de)(de)(de)(de)導(dao)(dao)體(ti)材(cai)(cai)料(liao)以及截面(mian)是(shi)否符合(he)的(de)(de)(de)(de)(de)(de)重(zhong)要(yao)指標。當(dang)導(dao)(dao)體(ti)電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)(zu)超(chao)標時(shi)，就增大了電(dian)(dian)(dian)(dian)(dian)流在(zai)線路上通過時(shi)的(de)(de)(de)(de)(de)(de)損耗，加(jia)(jia)劇了電(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)纜的(de)(de)(de)(de)(de)(de)發(fa)熱。導(dao)(dao)體(ti)電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)(zu)不合(he)格的(de)(de)(de)(de)(de)(de)原(yuan)因，主要(yao)進(jin)企業(ye)為了降低成本，將占原(yuan)材(cai)(cai)料(liao)成本80%的(de)(de)(de)(de)(de)(de)銅(tong)材(cai)(cai)縮(suo)水，要(yao)么降低導(dao)(dao)體(ti)的(de)(de)(de)(de)(de)(de)截面(mian)積，要(yao)么使(shi)用含雜質過高的(de)(de)(de)(de)(de)(de)再(zai)生銅(tong)，這樣(yang)致使(shi)電(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)纜的(de)(de)(de)(de)(de)(de)導(dao)(dao)體(ti)電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)(zu)嚴重(zhong)超(chao)標，在(zai)使(shi)用過程中除易(yi)引發(fa)火災，還會(hui)加(jia)(jia)速包覆在(zai)電(dian)(dian)(dian)(dian)(dian)線外的(de)(de)(de)(de)(de)(de)絕緣層的(de)(de)(de)(de)(de)(de)老化。

在購(gou)買(mai)電(dian)(dian)線電(dian)(dian)纜的過(guo)程中，消費者應注意(yi)以下幾個事

第(di)一、要(yao)觀察電線的(de)(de)外觀。合格產品的(de)(de)絕(jue)緣(yuan)（護套）層柔(rou)軟(ruan)、有韌性(xing)和伸縮性(xing)、表面層緊密、光滑(hua)、無(wu)粗(cu)糙感。如果(guo)包(bao)裹電線的(de)(de)塑料很容易被剝去，則存在(zai)塑料強(qiang)度不夠的(de)(de)問題。

第二(er)、要(yao)看電線的截(jie)面(mian)。合格(ge)產品的銅芯(xin)或鋁芯(xin)表面(mian)應該具有金(jin)屬光澤，表面(mian)發黑的銅或表面(mian)發白的鋁說(shuo)明(ming)已被氧化。

第三、在購買電(dian)線(xian)時應注意查(cha)看(kan)質量合(he)格(ge)證書。如果電(dian)線(xian)的質量合(he)格(ge)，那(nei)么其電(dian)線(xian)質量應該也受過檢驗，不(bu)會有太(tai)大的問(wen)題。
