不合(he)格電線(xian)電纜(lan)的危害

電(dian)線電(dian)纜(lan)是(shi)用于傳輸(shu)電(dian)力(li)、傳輸(shu)信息和實現電(dian)磁能量轉(zhuan)換的一大類電(dian)工產(chan)(chan)品(pin)。在抽查過程中(zhong)，發現了大量的不合(he)格產(chan)(chan)品(pin)，這(zhe)些劣質(zhi)產(chan)(chan)品(pin)給(gei)電(dian)力(li)系統正常運行(xing)埋下(xia)諸多隱患。

1、標(biao)(biao)志不合格的電(dian)(dian)線電(dian)(dian)纜(lan)。標(biao)(biao)志是電(dian)(dian)線電(dian)(dian)纜(lan)使用(yong)識別產品基本信息的主要途徑，根據標(biao)(biao)準規(gui)定標(biao)(biao)志的主要內容是：產品型號、規(gui)格、標(biao)(biao)準號、廠名、產地等(deng)在一定的標(biao)(biao)示(shi)間距(ju)內，當標(biao)(biao)志不合格時，會造成施工人員(yuan)識別錯(cuo)誤(wu)，嚴重(zhong)時會引發(fa)電(dian)(dian)氣(qi)事故。

2、結構(gou)尺寸不(bu)合格的電(dian)線(xian)電(dian)纜。結構(gou)尺寸的主要問題是護(hu)套(tao)厚度(du)，絕緣(yuan)厚度(du)，當電(dian)纜的護(hu)套(tao)和絕緣(yuan)厚度(du)不(bu)達標時(shi)，致(zhi)(zhi)使電(dian)線(xian)電(dian)纜耐電(dian)氣(qi)強度(du)會嚴重降(jiang)低，導致(zhi)(zhi)電(dian)線(xian)電(dian)纜的使用壽命縮(suo)短(duan)，嚴重時(shi)可導致(zhi)(zhi)電(dian)線(xian)電(dian)纜被擊穿(chuan)，絕緣(yuan)（護(hu)套(tao)）層(ceng)起(qi)不(bu)到正常保護(hu)作用，從而發生(sheng)電(dian)氣(qi)短(duan)路和火(huo)災(zai)等(deng)現(xian)象。

3、護套式絕(jue)緣老化前(qian)的(de)抗(kang)張(zhang)(zhang)強度、伸(shen)長(chang)(chang)率(lv)合(he)格(ge)的(de)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜。絕(jue)緣護套老化前(qian)的(de)抗(kang)張(zhang)(zhang)強度、伸(shen)長(chang)(chang)率(lv)不(bu)(bu)合(he)格(ge)直接大大縮(suo)短電(dian)(dian)(dian)線電(dian)(dian)(dian)纜的(de)工作用(yong)壽命，而且在施工或在長(chang)(chang)時間通(tong)電(dian)(dian)(dian)且溫度較高的(de)環(huan)境中，極易出現絕(jue)緣體斷裂，致使(shi)帶電(dian)(dian)(dian)導體裸露，發生(sheng)(sheng)能(neng)觸電(dian)(dian)(dian)式短路危(wei)險。其不(bu)(bu)合(he)格(ge)的(de)主(zhu)要原因是使(shi)用(yong)了再生(sheng)(sheng)料(liao)生(sheng)(sheng)產，以(yi)降低產品(pin)成本，二(er)是不(bu)(bu)具備生(sheng)(sheng)產資格(ge)小(xiao)型企業。

4、導體(ti)(ti)(ti)(ti)電(dian)阻(zu)不合格的(de)(de)電(dian)線。導體(ti)(ti)(ti)(ti)電(dian)阻(zu)主要(yao)(yao)是(shi)考(kao)核電(dian)線電(dian)纜的(de)(de)導體(ti)(ti)(ti)(ti)材料以及截面是(shi)否(fou)符(fu)合的(de)(de)重要(yao)(yao)指標(biao)。當導體(ti)(ti)(ti)(ti)電(dian)阻(zu)超(chao)標(biao)時，就增大(da)了(le)(le)電(dian)流(liu)在線路上通過(guo)(guo)時的(de)(de)損耗(hao)，加劇(ju)了(le)(le)電(dian)線電(dian)纜的(de)(de)發熱。導體(ti)(ti)(ti)(ti)電(dian)阻(zu)不合格的(de)(de)原(yuan)因，主要(yao)(yao)進企(qi)業(ye)為了(le)(le)降低成(cheng)本，將占原(yuan)材料成(cheng)本80%的(de)(de)銅(tong)材縮水，要(yao)(yao)么(me)降低導體(ti)(ti)(ti)(ti)的(de)(de)截面積，要(yao)(yao)么(me)使用(yong)(yong)含雜質過(guo)(guo)高的(de)(de)再生銅(tong)，這樣致使電(dian)線電(dian)纜的(de)(de)導體(ti)(ti)(ti)(ti)電(dian)阻(zu)嚴重超(chao)標(biao)，在使用(yong)(yong)過(guo)(guo)程中除易引發火災，還會加速包覆在電(dian)線外的(de)(de)絕緣層的(de)(de)老(lao)化。

在購買(mai)電線電纜的過程中，消費者(zhe)應注意以下幾(ji)個(ge)事

第(di)一、要觀(guan)察電(dian)線(xian)的外觀(guan)。合格(ge)產品(pin)的絕緣（護(hu)套）層(ceng)柔軟、有韌性和(he)伸縮性、表面(mian)層(ceng)緊密、光滑、無粗(cu)糙感。如果包裹電(dian)線(xian)的塑料(liao)很(hen)容易被剝去，則存在塑料(liao)強度不夠的問題。

第二、要看電線的截(jie)面(mian)。合格產品(pin)的銅芯或鋁芯表(biao)面(mian)應該(gai)具有金屬光(guang)澤，表(biao)面(mian)發黑(hei)的銅或表(biao)面(mian)發白的鋁說明(ming)已(yi)被氧(yang)化。

第三、在購買電線時(shi)應注(zhu)意查看質量(liang)合格證(zheng)書。如果(guo)電線的質量(liang)合格，那么其電線質量(liang)應該(gai)也受過檢驗，不會有太大的問題。
