不合(he)格電線電纜的(de)危害

電(dian)(dian)線電(dian)(dian)纜(lan)是(shi)用于傳輸電(dian)(dian)力(li)、傳輸信(xin)息和實現電(dian)(dian)磁能(neng)量(liang)轉換的一大(da)類電(dian)(dian)工產品。在抽查過(guo)程中(zhong)，發現了大(da)量(liang)的不合格產品，這些(xie)劣質(zhi)產品給電(dian)(dian)力(li)系統(tong)正常運行(xing)埋下諸多隱患。

1、標(biao)(biao)(biao)志(zhi)(zhi)不合(he)格的電線電纜。標(biao)(biao)(biao)志(zhi)(zhi)是電線電纜使用識別(bie)產品基本信息的主要(yao)途徑，根據標(biao)(biao)(biao)準規定(ding)(ding)標(biao)(biao)(biao)志(zhi)(zhi)的主要(yao)內(nei)容是：產品型(xing)號、規格、標(biao)(biao)(biao)準號、廠名、產地等(deng)在一定(ding)(ding)的標(biao)(biao)(biao)示間距(ju)內(nei)，當標(biao)(biao)(biao)志(zhi)(zhi)不合(he)格時(shi)，會(hui)造成(cheng)施工(gong)人員識別(bie)錯誤，嚴重時(shi)會(hui)引發電氣(qi)事故。

2、結(jie)構(gou)尺寸不(bu)合格的電(dian)線(xian)電(dian)纜。結(jie)構(gou)尺寸的主(zhu)要問題是護套(tao)厚度(du)，絕(jue)緣厚度(du)，當電(dian)纜的護套(tao)和絕(jue)緣厚度(du)不(bu)達標時(shi)，致使(shi)電(dian)線(xian)電(dian)纜耐電(dian)氣強度(du)會嚴重(zhong)降低，導(dao)致電(dian)線(xian)電(dian)纜的使(shi)用(yong)壽命縮短(duan)，嚴重(zhong)時(shi)可導(dao)致電(dian)線(xian)電(dian)纜被擊(ji)穿，絕(jue)緣（護套(tao)）層起不(bu)到正常保護作用(yong)，從而發生電(dian)氣短(duan)路和火災等現象。

3、護(hu)套式絕緣老化前的抗張強度、伸(shen)長(chang)率合格的電(dian)線電(dian)纜。絕緣護(hu)套老化前的抗張強度、伸(shen)長(chang)率不(bu)(bu)合格直(zhi)接大(da)大(da)縮(suo)短電(dian)線電(dian)纜的工作用壽命(ming)，而(er)且在(zai)施工或在(zai)長(chang)時間(jian)通電(dian)且溫(wen)度較高的環境中，極(ji)易出現絕緣體(ti)斷(duan)裂，致使帶電(dian)導體(ti)裸露，發生(sheng)能觸電(dian)式短路危(wei)險。其不(bu)(bu)合格的主要原因(yin)是(shi)使用了再生(sheng)料生(sheng)產，以降低(di)產品成本，二是(shi)不(bu)(bu)具備生(sheng)產資(zi)格小型企業。

4、導(dao)(dao)(dao)體(ti)電(dian)(dian)(dian)阻不合格(ge)的(de)(de)(de)(de)電(dian)(dian)(dian)線(xian)(xian)。導(dao)(dao)(dao)體(ti)電(dian)(dian)(dian)阻主(zhu)要是考(kao)核電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)(lan)的(de)(de)(de)(de)導(dao)(dao)(dao)體(ti)材料(liao)以及截面是否符合的(de)(de)(de)(de)重要指標(biao)。當導(dao)(dao)(dao)體(ti)電(dian)(dian)(dian)阻超(chao)標(biao)時，就增大(da)了(le)(le)(le)電(dian)(dian)(dian)流在線(xian)(xian)路(lu)上(shang)通過時的(de)(de)(de)(de)損耗(hao)，加劇了(le)(le)(le)電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)(lan)的(de)(de)(de)(de)發(fa)熱。導(dao)(dao)(dao)體(ti)電(dian)(dian)(dian)阻不合格(ge)的(de)(de)(de)(de)原因，主(zhu)要進企業為了(le)(le)(le)降(jiang)低(di)成本，將占原材料(liao)成本80%的(de)(de)(de)(de)銅材縮水，要么降(jiang)低(di)導(dao)(dao)(dao)體(ti)的(de)(de)(de)(de)截面積(ji)，要么使用含(han)雜(za)質(zhi)過高的(de)(de)(de)(de)再生銅，這樣致(zhi)使電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜(lan)(lan)的(de)(de)(de)(de)導(dao)(dao)(dao)體(ti)電(dian)(dian)(dian)阻嚴重超(chao)標(biao)，在使用過程中(zhong)除易(yi)引發(fa)火災，還(huan)會加速(su)包(bao)覆(fu)在電(dian)(dian)(dian)線(xian)(xian)外的(de)(de)(de)(de)絕緣層的(de)(de)(de)(de)老化。

在(zai)購買電線(xian)電纜(lan)的過程中，消(xiao)費者應注意以下幾個事

第(di)一、要觀察(cha)電線的外(wai)觀。合格產品的絕(jue)緣（護套(tao)）層(ceng)柔軟、有韌性和伸縮性、表面層(ceng)緊密、光滑、無(wu)粗糙感。如(ru)果包裹(guo)電線的塑(su)料很容易被(bei)剝去，則存在塑(su)料強(qiang)度不夠的問(wen)題。

第二、要看電線的截面(mian)。合格(ge)產品的銅(tong)芯(xin)或鋁(lv)芯(xin)表(biao)面(mian)應該(gai)具(ju)有金屬光澤，表(biao)面(mian)發黑的銅(tong)或表(biao)面(mian)發白的鋁(lv)說明已被氧化。

第三、在購買(mai)電線(xian)時應注意查看質量(liang)合格(ge)證書。如果(guo)電線(xian)的質量(liang)合格(ge)，那么其電線(xian)質量(liang)應該也(ye)受過(guo)檢驗(yan)，不會有太大的問題。
