不合格電(dian)線(xian)電(dian)纜(lan)的(de)危害

電(dian)線電(dian)纜(lan)是用(yong)于傳輸電(dian)力、傳輸信息和實現電(dian)磁(ci)能(neng)量(liang)轉換(huan)的(de)(de)一(yi)大(da)類電(dian)工產(chan)品(pin)。在抽(chou)查過程(cheng)中，發現了大(da)量(liang)的(de)(de)不合格(ge)產(chan)品(pin)，這些劣質產(chan)品(pin)給電(dian)力系統正常運行埋下諸多(duo)隱患。

1、標(biao)(biao)(biao)志不(bu)合格(ge)的電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)。標(biao)(biao)(biao)志是電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)使(shi)用識別產品基本信息的主要途徑，根據標(biao)(biao)(biao)準規定標(biao)(biao)(biao)志的主要內容是：產品型(xing)號(hao)、規格(ge)、標(biao)(biao)(biao)準號(hao)、廠名、產地等在一定的標(biao)(biao)(biao)示間距內，當標(biao)(biao)(biao)志不(bu)合格(ge)時，會造成施工人(ren)員識別錯誤，嚴重時會引(yin)發電(dian)(dian)(dian)氣事故。

2、結構尺(chi)寸(cun)不合格的電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)(lan)。結構尺(chi)寸(cun)的主要問(wen)題(ti)是(shi)護(hu)套(tao)(tao)厚度(du)(du)，絕(jue)緣(yuan)厚度(du)(du)，當電(dian)(dian)(dian)纜(lan)(lan)的護(hu)套(tao)(tao)和(he)絕(jue)緣(yuan)厚度(du)(du)不達標時(shi)(shi)，致使電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)(lan)耐(nai)電(dian)(dian)(dian)氣強度(du)(du)會嚴(yan)重降低，導致電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)(lan)的使用(yong)(yong)壽命縮短，嚴(yan)重時(shi)(shi)可導致電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)(lan)被(bei)擊穿，絕(jue)緣(yuan)（護(hu)套(tao)(tao)）層(ceng)起(qi)不到正常保護(hu)作用(yong)(yong)，從(cong)而(er)發生電(dian)(dian)(dian)氣短路(lu)和(he)火災等現象。

3、護(hu)套式絕(jue)緣(yuan)老(lao)化(hua)前的(de)抗(kang)張強度(du)、伸長(chang)(chang)率合(he)格(ge)的(de)電(dian)線電(dian)纜。絕(jue)緣(yuan)護(hu)套老(lao)化(hua)前的(de)抗(kang)張強度(du)、伸長(chang)(chang)率不合(he)格(ge)直(zhi)接大大縮短電(dian)線電(dian)纜的(de)工作用(yong)(yong)壽命，而且在(zai)(zai)施工或(huo)在(zai)(zai)長(chang)(chang)時間通電(dian)且溫度(du)較高的(de)環境中(zhong)，極易出(chu)現絕(jue)緣(yuan)體斷裂，致使(shi)帶(dai)電(dian)導(dao)體裸(luo)露，發生能觸電(dian)式短路危險(xian)。其不合(he)格(ge)的(de)主要原因是(shi)使(shi)用(yong)(yong)了再生料生產(chan)，以(yi)降(jiang)低產(chan)品成本，二是(shi)不具備生產(chan)資格(ge)小型企業。

4、導體(ti)電(dian)阻不(bu)合(he)(he)(he)格(ge)的(de)(de)電(dian)線(xian)。導體(ti)電(dian)阻主要(yao)(yao)(yao)是考核電(dian)線(xian)電(dian)纜的(de)(de)導體(ti)材料(liao)以及截面(mian)是否(fou)符合(he)(he)(he)的(de)(de)重要(yao)(yao)(yao)指(zhi)標。當導體(ti)電(dian)阻超標時，就增(zeng)大了電(dian)流在線(xian)路上(shang)通(tong)過(guo)時的(de)(de)損(sun)耗，加(jia)劇了電(dian)線(xian)電(dian)纜的(de)(de)發熱。導體(ti)電(dian)阻不(bu)合(he)(he)(he)格(ge)的(de)(de)原(yuan)因，主要(yao)(yao)(yao)進(jin)企(qi)業為了降低成本，將占原(yuan)材料(liao)成本80%的(de)(de)銅材縮水，要(yao)(yao)(yao)么降低導體(ti)的(de)(de)截面(mian)積(ji)，要(yao)(yao)(yao)么使(shi)用(yong)(yong)含雜(za)質過(guo)高的(de)(de)再生(sheng)銅，這樣致(zhi)使(shi)電(dian)線(xian)電(dian)纜的(de)(de)導體(ti)電(dian)阻嚴重超標，在使(shi)用(yong)(yong)過(guo)程中除易引發火災，還會加(jia)速包(bao)覆在電(dian)線(xian)外的(de)(de)絕緣層(ceng)的(de)(de)老化。

在購買電線電纜的過程(cheng)中(zhong)，消費(fei)者應注意以下幾(ji)個事

第一(yi)、要觀(guan)(guan)察(cha)電線的(de)外觀(guan)(guan)。合格(ge)產品(pin)的(de)絕(jue)緣（護套）層(ceng)柔(rou)軟、有韌性和伸縮性、表(biao)面層(ceng)緊密(mi)、光(guang)滑、無粗糙感。如(ru)果(guo)包(bao)裹電線的(de)塑(su)料(liao)很容(rong)易被剝去，則存在塑(su)料(liao)強度不夠的(de)問題。

第二、要看電線的截面(mian)(mian)。合(he)格產品的銅芯或鋁芯表面(mian)(mian)應該具有金(jin)屬光澤，表面(mian)(mian)發黑的銅或表面(mian)(mian)發白的鋁說(shuo)明已被氧化。

第三、在購買電(dian)線時(shi)應注意查看(kan)質(zhi)量(liang)合格證書。如果電(dian)線的質(zhi)量(liang)合格，那么其(qi)電(dian)線質(zhi)量(liang)應該也受過檢驗，不會有太大的問(wen)題。
