不合格(ge)電(dian)線電(dian)纜的危害

電(dian)(dian)(dian)線電(dian)(dian)(dian)纜是用于傳輸電(dian)(dian)(dian)力(li)、傳輸信息和實現電(dian)(dian)(dian)磁能(neng)量(liang)轉換的一(yi)大類電(dian)(dian)(dian)工(gong)產(chan)(chan)品(pin)。在抽查過(guo)程中，發現了大量(liang)的不合格產(chan)(chan)品(pin)，這些(xie)劣質產(chan)(chan)品(pin)給(gei)電(dian)(dian)(dian)力(li)系(xi)統正常運行埋下(xia)諸多隱患(huan)。

1、標(biao)志(zhi)不合(he)格的(de)(de)電線電纜。標(biao)志(zhi)是(shi)電線電纜使用識(shi)別產品(pin)基本信(xin)息的(de)(de)主要途徑，根據標(biao)準(zhun)規定標(biao)志(zhi)的(de)(de)主要內(nei)容是(shi)：產品(pin)型號(hao)、規格、標(biao)準(zhun)號(hao)、廠名、產地(di)等(deng)在一定的(de)(de)標(biao)示間距內(nei)，當標(biao)志(zhi)不合(he)格時，會造成(cheng)施(shi)工人員(yuan)識(shi)別錯誤(wu)，嚴重時會引發電氣事故。

2、結構尺(chi)寸(cun)不合格的(de)電(dian)線電(dian)纜(lan)(lan)。結構尺(chi)寸(cun)的(de)主要問(wen)題是(shi)護套厚(hou)度(du)，絕緣(yuan)厚(hou)度(du)，當電(dian)纜(lan)(lan)的(de)護套和(he)絕緣(yuan)厚(hou)度(du)不達標時(shi)，致使(shi)電(dian)線電(dian)纜(lan)(lan)耐電(dian)氣(qi)強(qiang)度(du)會(hui)嚴重(zhong)降(jiang)低(di)，導(dao)(dao)致電(dian)線電(dian)纜(lan)(lan)的(de)使(shi)用壽(shou)命縮短，嚴重(zhong)時(shi)可導(dao)(dao)致電(dian)線電(dian)纜(lan)(lan)被擊穿，絕緣(yuan)（護套）層起不到正(zheng)常保護作用，從(cong)而發生電(dian)氣(qi)短路和(he)火災(zai)等現象。

3、護套式絕(jue)(jue)(jue)緣(yuan)老化(hua)前(qian)的(de)(de)抗張強度、伸長(chang)率(lv)合格的(de)(de)電(dian)(dian)線(xian)電(dian)(dian)纜(lan)。絕(jue)(jue)(jue)緣(yuan)護套老化(hua)前(qian)的(de)(de)抗張強度、伸長(chang)率(lv)不(bu)合格直接(jie)大(da)大(da)縮(suo)短(duan)電(dian)(dian)線(xian)電(dian)(dian)纜(lan)的(de)(de)工作用壽命，而(er)且(qie)在(zai)施(shi)工或(huo)在(zai)長(chang)時間通電(dian)(dian)且(qie)溫度較(jiao)高(gao)的(de)(de)環境中，極易出現絕(jue)(jue)(jue)緣(yuan)體斷裂，致使帶(dai)電(dian)(dian)導(dao)體裸露，發生能觸電(dian)(dian)式短(duan)路危險。其不(bu)合格的(de)(de)主(zhu)要原因是使用了再生料(liao)生產(chan)，以(yi)降低(di)產(chan)品成(cheng)本，二是不(bu)具備生產(chan)資(zi)格小型企(qi)業。

4、導(dao)(dao)體(ti)電(dian)(dian)(dian)(dian)阻(zu)不合(he)(he)格的(de)(de)(de)電(dian)(dian)(dian)(dian)線(xian)。導(dao)(dao)體(ti)電(dian)(dian)(dian)(dian)阻(zu)主(zhu)要是考核電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)的(de)(de)(de)導(dao)(dao)體(ti)材(cai)料(liao)(liao)以及截面是否(fou)符合(he)(he)的(de)(de)(de)重要指標。當導(dao)(dao)體(ti)電(dian)(dian)(dian)(dian)阻(zu)超(chao)標時(shi)，就增(zeng)大了(le)(le)電(dian)(dian)(dian)(dian)流(liu)在線(xian)路上通過時(shi)的(de)(de)(de)損耗，加劇了(le)(le)電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)的(de)(de)(de)發熱。導(dao)(dao)體(ti)電(dian)(dian)(dian)(dian)阻(zu)不合(he)(he)格的(de)(de)(de)原(yuan)因(yin)，主(zhu)要進企業為了(le)(le)降低(di)成本(ben)，將占原(yuan)材(cai)料(liao)(liao)成本(ben)80%的(de)(de)(de)銅(tong)(tong)材(cai)縮水，要么降低(di)導(dao)(dao)體(ti)的(de)(de)(de)截面積，要么使(shi)用含雜(za)質過高的(de)(de)(de)再(zai)生銅(tong)(tong)，這樣致使(shi)電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)的(de)(de)(de)導(dao)(dao)體(ti)電(dian)(dian)(dian)(dian)阻(zu)嚴(yan)重超(chao)標，在使(shi)用過程中除易引發火災，還會加速包覆在電(dian)(dian)(dian)(dian)線(xian)外的(de)(de)(de)絕緣層(ceng)的(de)(de)(de)老化。

在購買(mai)電線電纜的(de)過程中(zhong)，消費者應注意以下幾個事

第一、要觀察(cha)電線的外觀。合格產(chan)品的絕緣（護套）層(ceng)柔軟、有韌性和伸縮性、表面層(ceng)緊密、光滑、無粗(cu)糙感。如果(guo)包(bao)裹電線的塑料(liao)很容易被剝去，則存在塑料(liao)強度不夠的問題。

第(di)二、要看電線的截面(mian)(mian)。合格產(chan)品的銅芯或鋁芯表面(mian)(mian)應該具有金屬光澤，表面(mian)(mian)發黑(hei)的銅或表面(mian)(mian)發白的鋁說明已被氧化(hua)。

第三、在(zai)購買電(dian)線(xian)時應(ying)注意查(cha)看質量合格證書。如果電(dian)線(xian)的質量合格，那么其電(dian)線(xian)質量應(ying)該也受過檢驗，不(bu)會有太大的問題。
