不(bu)合(he)格電線電纜的危害

電(dian)(dian)(dian)線電(dian)(dian)(dian)纜是用(yong)于傳(chuan)輸電(dian)(dian)(dian)力、傳(chuan)輸信息和實(shi)現(xian)電(dian)(dian)(dian)磁(ci)能(neng)量轉換的(de)一(yi)大(da)類(lei)電(dian)(dian)(dian)工產(chan)品。在(zai)抽查過程中，發現(xian)了(le)大(da)量的(de)不合格產(chan)品，這(zhe)些劣質產(chan)品給(gei)電(dian)(dian)(dian)力系(xi)統(tong)正(zheng)常運行埋下諸(zhu)多隱患。

1、標(biao)(biao)志(zhi)(zhi)不(bu)合格(ge)(ge)(ge)的電(dian)(dian)線電(dian)(dian)纜。標(biao)(biao)志(zhi)(zhi)是電(dian)(dian)線電(dian)(dian)纜使(shi)用識別(bie)產(chan)品基本信息的主要途徑，根據標(biao)(biao)準(zhun)規定(ding)標(biao)(biao)志(zhi)(zhi)的主要內(nei)容是：產(chan)品型號、規格(ge)(ge)(ge)、標(biao)(biao)準(zhun)號、廠(chang)名、產(chan)地等在一(yi)定(ding)的標(biao)(biao)示(shi)間(jian)距(ju)內(nei)，當標(biao)(biao)志(zhi)(zhi)不(bu)合格(ge)(ge)(ge)時(shi)，會造成施工(gong)人員識別(bie)錯誤(wu)，嚴重時(shi)會引(yin)發(fa)電(dian)(dian)氣事(shi)故。

2、結構尺寸(cun)不合格的電線(xian)(xian)電纜(lan)(lan)。結構尺寸(cun)的主要問(wen)題是(shi)護(hu)套(tao)厚(hou)度(du)，絕(jue)緣(yuan)厚(hou)度(du)，當(dang)電纜(lan)(lan)的護(hu)套(tao)和絕(jue)緣(yuan)厚(hou)度(du)不達標時，致(zhi)(zhi)使(shi)電線(xian)(xian)電纜(lan)(lan)耐電氣強(qiang)度(du)會嚴(yan)重降低，導(dao)(dao)致(zhi)(zhi)電線(xian)(xian)電纜(lan)(lan)的使(shi)用壽命縮短(duan)，嚴(yan)重時可導(dao)(dao)致(zhi)(zhi)電線(xian)(xian)電纜(lan)(lan)被(bei)擊(ji)穿，絕(jue)緣(yuan)（護(hu)套(tao)）層起不到正常保護(hu)作用，從而發(fa)生電氣短(duan)路(lu)和火災等現象。

3、護套式(shi)絕(jue)緣老化前(qian)的抗張(zhang)強(qiang)(qiang)度、伸長(chang)率(lv)合格(ge)的電(dian)線電(dian)纜(lan)。絕(jue)緣護套老化前(qian)的抗張(zhang)強(qiang)(qiang)度、伸長(chang)率(lv)不(bu)合格(ge)直接大大縮(suo)短(duan)電(dian)線電(dian)纜(lan)的工(gong)作用壽命，而且(qie)在施工(gong)或在長(chang)時間通電(dian)且(qie)溫度較(jiao)高的環境(jing)中，極易出現絕(jue)緣體(ti)斷裂，致使(shi)帶電(dian)導(dao)體(ti)裸露，發生能觸電(dian)式(shi)短(duan)路危險。其不(bu)合格(ge)的主要原因是使(shi)用了再(zai)生料生產(chan)，以(yi)降低產(chan)品成本(ben)，二是不(bu)具備生產(chan)資格(ge)小型企業。

4、導體(ti)電(dian)阻(zu)不合格的(de)(de)電(dian)線(xian)。導體(ti)電(dian)阻(zu)主(zhu)要是考(kao)核電(dian)線(xian)電(dian)纜(lan)的(de)(de)導體(ti)材(cai)料(liao)(liao)以(yi)及截(jie)面是否符合的(de)(de)重(zhong)要指標(biao)。當(dang)導體(ti)電(dian)阻(zu)超標(biao)時，就增(zeng)大(da)了(le)電(dian)流(liu)在線(xian)路上通過(guo)時的(de)(de)損耗，加(jia)劇了(le)電(dian)線(xian)電(dian)纜(lan)的(de)(de)發熱(re)。導體(ti)電(dian)阻(zu)不合格的(de)(de)原因，主(zhu)要進企業為了(le)降低(di)成(cheng)本，將占原材(cai)料(liao)(liao)成(cheng)本80%的(de)(de)銅材(cai)縮水，要么降低(di)導體(ti)的(de)(de)截(jie)面積，要么使(shi)用含雜質過(guo)高的(de)(de)再生(sheng)銅，這樣致使(shi)電(dian)線(xian)電(dian)纜(lan)的(de)(de)導體(ti)電(dian)阻(zu)嚴重(zhong)超標(biao)，在使(shi)用過(guo)程中除(chu)易(yi)引發火(huo)災，還會加(jia)速包覆在電(dian)線(xian)外的(de)(de)絕(jue)緣層的(de)(de)老化。

在購買電線電纜(lan)的(de)過(guo)程中，消費(fei)者應注意以(yi)下幾個事

第一、要觀(guan)察電(dian)線(xian)的(de)外(wai)觀(guan)。合格產品(pin)的(de)絕緣（護套）層柔(rou)軟(ruan)、有韌性和伸縮性、表面層緊密、光滑、無粗(cu)糙感(gan)。如果包裹(guo)電(dian)線(xian)的(de)塑料很容易被剝(bo)去，則存在塑料強度不夠的(de)問題(ti)。

第(di)二、要看(kan)電線的(de)(de)截面(mian)。合格產品的(de)(de)銅芯(xin)或鋁芯(xin)表面(mian)應該(gai)具(ju)有金屬光(guang)澤，表面(mian)發黑的(de)(de)銅或表面(mian)發白(bai)的(de)(de)鋁說明已被氧化。

第三、在購(gou)買電線時應(ying)注意查看質量(liang)合格(ge)證(zheng)書。如(ru)果電線的質量(liang)合格(ge)，那么其電線質量(liang)應(ying)該也(ye)受(shou)過檢驗，不會(hui)有太(tai)大的問(wen)題。
