不合格(ge)電(dian)線電(dian)纜的(de)危害

電(dian)(dian)線電(dian)(dian)纜是用于傳輸(shu)電(dian)(dian)力、傳輸(shu)信息(xi)和實現電(dian)(dian)磁(ci)能量轉(zhuan)換的一大類電(dian)(dian)工產品。在抽查過(guo)程中，發(fa)現了大量的不合(he)格產品，這些劣質產品給電(dian)(dian)力系統(tong)正常(chang)運行埋下(xia)諸多隱(yin)患。

1、標(biao)(biao)志(zhi)不合格(ge)(ge)的(de)電(dian)線(xian)電(dian)纜。標(biao)(biao)志(zhi)是電(dian)線(xian)電(dian)纜使(shi)用識(shi)別產品(pin)基本信息的(de)主要(yao)途徑(jing)，根據(ju)標(biao)(biao)準(zhun)規定(ding)(ding)標(biao)(biao)志(zhi)的(de)主要(yao)內容是：產品(pin)型號、規格(ge)(ge)、標(biao)(biao)準(zhun)號、廠(chang)名、產地等(deng)在一定(ding)(ding)的(de)標(biao)(biao)示(shi)間距(ju)內，當(dang)標(biao)(biao)志(zhi)不合格(ge)(ge)時，會造(zao)成施工人員識(shi)別錯誤(wu)，嚴重時會引發電(dian)氣事故。

2、結(jie)構(gou)尺(chi)寸(cun)不(bu)(bu)合格的(de)(de)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜。結(jie)構(gou)尺(chi)寸(cun)的(de)(de)主要問題是護(hu)(hu)套(tao)厚(hou)(hou)度，絕(jue)緣(yuan)厚(hou)(hou)度，當電(dian)(dian)(dian)纜的(de)(de)護(hu)(hu)套(tao)和絕(jue)緣(yuan)厚(hou)(hou)度不(bu)(bu)達標(biao)時(shi)，致使電(dian)(dian)(dian)線電(dian)(dian)(dian)纜耐電(dian)(dian)(dian)氣強度會嚴重(zhong)降低(di)，導(dao)致電(dian)(dian)(dian)線電(dian)(dian)(dian)纜的(de)(de)使用壽命縮短，嚴重(zhong)時(shi)可導(dao)致電(dian)(dian)(dian)線電(dian)(dian)(dian)纜被擊穿，絕(jue)緣(yuan)（護(hu)(hu)套(tao)）層起(qi)不(bu)(bu)到正常保護(hu)(hu)作(zuo)用，從而發生電(dian)(dian)(dian)氣短路(lu)和火災等(deng)現象。

3、護套式絕緣老化前的(de)抗(kang)(kang)張(zhang)強度、伸長率(lv)合(he)格(ge)的(de)電(dian)(dian)線電(dian)(dian)纜(lan)。絕緣護套老化前的(de)抗(kang)(kang)張(zhang)強度、伸長率(lv)不合(he)格(ge)直接大大縮短電(dian)(dian)線電(dian)(dian)纜(lan)的(de)工(gong)作用(yong)壽命，而(er)且在(zai)施(shi)工(gong)或在(zai)長時(shi)間通電(dian)(dian)且溫度較(jiao)高的(de)環境(jing)中，極易出現絕緣體斷(duan)裂，致使(shi)帶電(dian)(dian)導體裸(luo)露，發生(sheng)能觸(chu)電(dian)(dian)式短路(lu)危險。其(qi)不合(he)格(ge)的(de)主要原因是使(shi)用(yong)了再生(sheng)料生(sheng)產，以(yi)降低產品成本，二是不具備(bei)生(sheng)產資格(ge)小型企業(ye)。

4、導(dao)體(ti)電(dian)(dian)阻不(bu)合(he)格(ge)的(de)(de)(de)(de)電(dian)(dian)線(xian)。導(dao)體(ti)電(dian)(dian)阻主(zhu)要(yao)是考(kao)核電(dian)(dian)線(xian)電(dian)(dian)纜(lan)的(de)(de)(de)(de)導(dao)體(ti)材(cai)料(liao)以(yi)及截(jie)面是否(fou)符合(he)的(de)(de)(de)(de)重(zhong)要(yao)指標。當導(dao)體(ti)電(dian)(dian)阻超(chao)標時(shi)，就(jiu)增大了電(dian)(dian)流在(zai)(zai)線(xian)路上通(tong)過時(shi)的(de)(de)(de)(de)損耗，加劇了電(dian)(dian)線(xian)電(dian)(dian)纜(lan)的(de)(de)(de)(de)發熱。導(dao)體(ti)電(dian)(dian)阻不(bu)合(he)格(ge)的(de)(de)(de)(de)原(yuan)因，主(zhu)要(yao)進企業(ye)為了降(jiang)低成本，將占原(yuan)材(cai)料(liao)成本80%的(de)(de)(de)(de)銅(tong)材(cai)縮水，要(yao)么降(jiang)低導(dao)體(ti)的(de)(de)(de)(de)截(jie)面積，要(yao)么使(shi)用含雜質過高的(de)(de)(de)(de)再生(sheng)銅(tong)，這(zhe)樣致使(shi)電(dian)(dian)線(xian)電(dian)(dian)纜(lan)的(de)(de)(de)(de)導(dao)體(ti)電(dian)(dian)阻嚴(yan)重(zhong)超(chao)標，在(zai)(zai)使(shi)用過程中除易引發火災，還會加速(su)包(bao)覆在(zai)(zai)電(dian)(dian)線(xian)外(wai)的(de)(de)(de)(de)絕(jue)緣層(ceng)的(de)(de)(de)(de)老化。

在購買電線電纜的過程中，消費者應注意以(yi)下幾個事

第一、要觀(guan)察電線(xian)的外(wai)觀(guan)。合格產品(pin)的絕緣（護套）層柔軟、有韌性(xing)和(he)伸縮性(xing)、表面層緊密、光滑、無粗糙感。如果(guo)包裹(guo)電線(xian)的塑料很容易被剝去，則存在塑料強(qiang)度不夠的問題。

第(di)二、要(yao)看電線的截面(mian)(mian)。合格產品(pin)的銅芯或(huo)(huo)鋁芯表(biao)面(mian)(mian)應該具有金屬光澤，表(biao)面(mian)(mian)發黑的銅或(huo)(huo)表(biao)面(mian)(mian)發白的鋁說明已被氧化。

第三、在購(gou)買電線(xian)(xian)時應(ying)注意(yi)查看質(zhi)量合格證書。如果電線(xian)(xian)的(de)質(zhi)量合格，那么其電線(xian)(xian)質(zhi)量應(ying)該也受過檢驗，不會有太大的(de)問題。
