不合格電線(xian)電纜的危害

電(dian)(dian)線電(dian)(dian)纜(lan)是用于傳(chuan)輸(shu)電(dian)(dian)力、傳(chuan)輸(shu)信息和實現(xian)(xian)電(dian)(dian)磁能量(liang)(liang)轉(zhuan)換(huan)的(de)(de)一大(da)類電(dian)(dian)工產品(pin)。在抽查過程中，發現(xian)(xian)了(le)大(da)量(liang)(liang)的(de)(de)不合格產品(pin)，這些劣質產品(pin)給(gei)電(dian)(dian)力系統正常運行埋下諸(zhu)多隱患。

1、標(biao)志(zhi)不(bu)合格(ge)(ge)的(de)電線電纜(lan)。標(biao)志(zhi)是電線電纜(lan)使用(yong)識別產品(pin)基(ji)本信息的(de)主(zhu)要途徑，根據標(biao)準(zhun)規定標(biao)志(zhi)的(de)主(zhu)要內(nei)容是：產品(pin)型號(hao)、規格(ge)(ge)、標(biao)準(zhun)號(hao)、廠(chang)名、產地(di)等在一定的(de)標(biao)示間距(ju)內(nei)，當標(biao)志(zhi)不(bu)合格(ge)(ge)時，會(hui)造成施工人員識別錯誤，嚴(yan)重時會(hui)引發電氣事故。

2、結構(gou)尺(chi)(chi)寸不合(he)格的(de)電(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)纜(lan)。結構(gou)尺(chi)(chi)寸的(de)主(zhu)要問(wen)題是護(hu)套厚度，絕(jue)緣厚度，當電(dian)(dian)纜(lan)的(de)護(hu)套和絕(jue)緣厚度不達標時，致(zhi)使電(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)纜(lan)耐電(dian)(dian)氣(qi)強(qiang)度會嚴重(zhong)降低，導致(zhi)電(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)纜(lan)的(de)使用壽命縮(suo)短，嚴重(zhong)時可導致(zhi)電(dian)(dian)線(xian)(xian)(xian)電(dian)(dian)纜(lan)被(bei)擊穿，絕(jue)緣（護(hu)套）層起不到(dao)正常保護(hu)作用，從而發生電(dian)(dian)氣(qi)短路(lu)和火災(zai)等現(xian)象。

3、護套式絕緣老化前的抗張強(qiang)度(du)(du)、伸(shen)長(chang)率合(he)格的電(dian)線電(dian)纜。絕緣護套老化前的抗張強(qiang)度(du)(du)、伸(shen)長(chang)率不(bu)合(he)格直接大大縮短電(dian)線電(dian)纜的工作(zuo)用壽(shou)命(ming)，而且在施工或在長(chang)時(shi)間通電(dian)且溫度(du)(du)較高的環境(jing)中，極易出現絕緣體(ti)斷裂，致使(shi)帶電(dian)導體(ti)裸露，發(fa)生能觸(chu)電(dian)式短路危險。其(qi)不(bu)合(he)格的主要原(yuan)因是(shi)使(shi)用了再生料生產(chan)，以降低產(chan)品(pin)成本，二是(shi)不(bu)具備生產(chan)資格小型企(qi)業。

4、導(dao)體(ti)(ti)電(dian)(dian)阻不(bu)合(he)格的(de)電(dian)(dian)線(xian)(xian)。導(dao)體(ti)(ti)電(dian)(dian)阻主(zhu)要(yao)(yao)是(shi)考核電(dian)(dian)線(xian)(xian)電(dian)(dian)纜的(de)導(dao)體(ti)(ti)材料以及截面(mian)是(shi)否(fou)符(fu)合(he)的(de)重要(yao)(yao)指標(biao)。當導(dao)體(ti)(ti)電(dian)(dian)阻超標(biao)時，就增大了(le)電(dian)(dian)流(liu)在(zai)線(xian)(xian)路上通過時的(de)損(sun)耗，加(jia)劇了(le)電(dian)(dian)線(xian)(xian)電(dian)(dian)纜的(de)發熱。導(dao)體(ti)(ti)電(dian)(dian)阻不(bu)合(he)格的(de)原因(yin)，主(zhu)要(yao)(yao)進企業(ye)為(wei)了(le)降(jiang)低(di)成(cheng)本(ben)(ben)，將占(zhan)原材料成(cheng)本(ben)(ben)80%的(de)銅材縮(suo)水(shui)，要(yao)(yao)么降(jiang)低(di)導(dao)體(ti)(ti)的(de)截面(mian)積，要(yao)(yao)么使用(yong)含雜(za)質(zhi)過高的(de)再(zai)生銅，這樣致使電(dian)(dian)線(xian)(xian)電(dian)(dian)纜的(de)導(dao)體(ti)(ti)電(dian)(dian)阻嚴重超標(biao)，在(zai)使用(yong)過程中除(chu)易引發火災，還(huan)會加(jia)速包(bao)覆在(zai)電(dian)(dian)線(xian)(xian)外的(de)絕緣層的(de)老化。

在購買電線電纜的過(guo)程中，消費者應(ying)注意以(yi)下(xia)幾(ji)個(ge)事

第一、要觀察電(dian)線的(de)外觀。合格產品的(de)絕緣（護(hu)套）層(ceng)柔(rou)軟、有韌性(xing)和(he)伸(shen)縮性(xing)、表面層(ceng)緊密(mi)、光滑、無粗糙感。如(ru)果包裹電(dian)線的(de)塑料很容(rong)易被剝去(qu)，則存在塑料強度不(bu)夠的(de)問(wen)題。

第(di)二、要(yao)看電(dian)線的截(jie)面(mian)(mian)。合格產品的銅芯或鋁芯表面(mian)(mian)應(ying)該具有金(jin)屬光(guang)澤，表面(mian)(mian)發黑的銅或表面(mian)(mian)發白(bai)的鋁說明已(yi)被氧化。

第三、在購買電(dian)線時應注意查看質量(liang)合(he)格證(zheng)書。如(ru)果電(dian)線的質量(liang)合(he)格，那么其電(dian)線質量(liang)應該也受(shou)過檢驗(yan)，不會有太(tai)大的問題(ti)。
