不合格(ge)電(dian)線電(dian)纜的危害(hai)

電(dian)(dian)線(xian)電(dian)(dian)纜是用于傳(chuan)輸電(dian)(dian)力、傳(chuan)輸信息和(he)實現電(dian)(dian)磁能量轉換的(de)(de)一(yi)大類電(dian)(dian)工(gong)產品。在抽(chou)查過程中(zhong)，發現了大量的(de)(de)不合格(ge)產品，這些劣質(zhi)產品給電(dian)(dian)力系(xi)統(tong)正常運行埋下(xia)諸多隱患。

1、標(biao)志(zhi)不合(he)格(ge)的(de)電線電纜(lan)。標(biao)志(zhi)是電線電纜(lan)使用識別(bie)產(chan)品(pin)基本(ben)信(xin)息的(de)主(zhu)要途(tu)徑，根據(ju)標(biao)準(zhun)規(gui)定(ding)標(biao)志(zhi)的(de)主(zhu)要內(nei)容(rong)是：產(chan)品(pin)型(xing)號(hao)、規(gui)格(ge)、標(biao)準(zhun)號(hao)、廠(chang)名、產(chan)地等在(zai)一定(ding)的(de)標(biao)示間距內(nei)，當標(biao)志(zhi)不合(he)格(ge)時，會造成施工人員識別(bie)錯誤，嚴重時會引(yin)發電氣(qi)事故。

2、結構尺寸不合格的電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜。結構尺寸的主要問題是(shi)護套厚度，絕(jue)緣(yuan)厚度，當(dang)電(dian)(dian)(dian)纜的護套和(he)絕(jue)緣(yuan)厚度不達(da)標時(shi)，致(zhi)使電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜耐電(dian)(dian)(dian)氣強度會嚴重降低，導(dao)致(zhi)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜的使用壽命縮短(duan)，嚴重時(shi)可(ke)導(dao)致(zhi)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜被擊穿，絕(jue)緣(yuan)（護套）層(ceng)起不到正常(chang)保護作用，從而發生電(dian)(dian)(dian)氣短(duan)路(lu)和(he)火災等現(xian)象。

3、護套式絕(jue)緣(yuan)老化前(qian)的(de)抗張(zhang)(zhang)強度、伸長率合格(ge)的(de)電(dian)線電(dian)纜。絕(jue)緣(yuan)護套老化前(qian)的(de)抗張(zhang)(zhang)強度、伸長率不合格(ge)直接大大縮短電(dian)線電(dian)纜的(de)工作用壽(shou)命(ming)，而且(qie)在(zai)施工或(huo)在(zai)長時間通電(dian)且(qie)溫度較高的(de)環境中(zhong)，極易出現(xian)絕(jue)緣(yuan)體斷裂，致使(shi)帶電(dian)導體裸露，發(fa)生(sheng)能觸電(dian)式短路危險。其不合格(ge)的(de)主要原因是使(shi)用了再生(sheng)料生(sheng)產，以降(jiang)低產品(pin)成本，二是不具備(bei)生(sheng)產資格(ge)小型企業。

4、導體電(dian)(dian)(dian)(dian)阻不合(he)(he)格的(de)(de)電(dian)(dian)(dian)(dian)線(xian)。導體電(dian)(dian)(dian)(dian)阻主要是考核電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)的(de)(de)導體材(cai)料以(yi)及截面是否符合(he)(he)的(de)(de)重要指(zhi)標(biao)(biao)。當(dang)導體電(dian)(dian)(dian)(dian)阻超(chao)標(biao)(biao)時(shi)，就增大(da)了電(dian)(dian)(dian)(dian)流在線(xian)路上通過(guo)時(shi)的(de)(de)損(sun)耗，加劇了電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)的(de)(de)發(fa)(fa)熱。導體電(dian)(dian)(dian)(dian)阻不合(he)(he)格的(de)(de)原(yuan)因(yin)，主要進企業為了降低成本，將占原(yuan)材(cai)料成本80%的(de)(de)銅材(cai)縮水，要么(me)降低導體的(de)(de)截面積，要么(me)使(shi)(shi)用含雜質過(guo)高的(de)(de)再生銅，這樣(yang)致使(shi)(shi)電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)的(de)(de)導體電(dian)(dian)(dian)(dian)阻嚴(yan)重超(chao)標(biao)(biao)，在使(shi)(shi)用過(guo)程中除(chu)易引(yin)發(fa)(fa)火災，還會加速包覆在電(dian)(dian)(dian)(dian)線(xian)外的(de)(de)絕緣層的(de)(de)老化。

在購買(mai)電線電纜的(de)過(guo)程中，消費者應注(zhu)意(yi)以(yi)下幾個(ge)事

第(di)一(yi)、要觀察(cha)電線的外觀。合格(ge)產品的絕緣(yuan)（護套(tao)）層(ceng)柔軟、有韌性(xing)和伸縮性(xing)、表(biao)面層(ceng)緊密、光(guang)滑、無粗糙感(gan)。如果包裹電線的塑料很容易(yi)被(bei)剝去，則存(cun)在塑料強度不夠(gou)的問題(ti)。

第二、要(yao)看電線的(de)截面。合格產(chan)品的(de)銅芯或鋁芯表(biao)面應該具有(you)金屬(shu)光澤，表(biao)面發(fa)黑(hei)的(de)銅或表(biao)面發(fa)白的(de)鋁說明已被(bei)氧(yang)化。

第三、在購(gou)買(mai)電(dian)線(xian)時應(ying)注(zhu)意查看質(zhi)量合格證書(shu)。如果電(dian)線(xian)的質(zhi)量合格，那么其電(dian)線(xian)質(zhi)量應(ying)該也受過檢驗，不(bu)會有太(tai)大的問(wen)題。
