不合格電(dian)線電(dian)纜的危害(hai)

電(dian)線電(dian)纜是用于傳輸(shu)(shu)電(dian)力、傳輸(shu)(shu)信息和實現(xian)電(dian)磁能量(liang)轉換的一大(da)類電(dian)工產(chan)品(pin)。在(zai)抽查過程(cheng)中，發現(xian)了大(da)量(liang)的不合格產(chan)品(pin)，這(zhe)些劣質產(chan)品(pin)給電(dian)力系統正常運(yun)行(xing)埋下諸多隱患。

1、標(biao)(biao)志(zhi)(zhi)不合(he)格(ge)(ge)(ge)的(de)(de)電(dian)線(xian)電(dian)纜。標(biao)(biao)志(zhi)(zhi)是(shi)(shi)電(dian)線(xian)電(dian)纜使用(yong)識別產(chan)品(pin)基本信息的(de)(de)主要(yao)途徑，根據(ju)標(biao)(biao)準規定(ding)標(biao)(biao)志(zhi)(zhi)的(de)(de)主要(yao)內(nei)容是(shi)(shi)：產(chan)品(pin)型號(hao)、規格(ge)(ge)(ge)、標(biao)(biao)準號(hao)、廠名、產(chan)地等在一定(ding)的(de)(de)標(biao)(biao)示間距內(nei)，當標(biao)(biao)志(zhi)(zhi)不合(he)格(ge)(ge)(ge)時(shi)，會(hui)造成施工人員識別錯誤，嚴重時(shi)會(hui)引發電(dian)氣事故。

2、結構尺(chi)寸不合格的電(dian)線電(dian)纜(lan)(lan)。結構尺(chi)寸的主(zhu)要問題是護(hu)套厚度(du)(du)，絕(jue)緣(yuan)厚度(du)(du)，當電(dian)纜(lan)(lan)的護(hu)套和(he)絕(jue)緣(yuan)厚度(du)(du)不達標時，致使電(dian)線電(dian)纜(lan)(lan)耐電(dian)氣強度(du)(du)會嚴重(zhong)降低(di)，導致電(dian)線電(dian)纜(lan)(lan)的使用壽(shou)命縮短(duan)，嚴重(zhong)時可導致電(dian)線電(dian)纜(lan)(lan)被擊(ji)穿，絕(jue)緣(yuan)（護(hu)套）層起不到正常(chang)保護(hu)作(zuo)用，從而發生電(dian)氣短(duan)路和(he)火(huo)災等現象。

3、護(hu)套(tao)式(shi)絕(jue)緣(yuan)老化前的(de)抗張(zhang)強度(du)(du)、伸(shen)長(chang)(chang)率合格的(de)電(dian)(dian)線電(dian)(dian)纜(lan)。絕(jue)緣(yuan)護(hu)套(tao)老化前的(de)抗張(zhang)強度(du)(du)、伸(shen)長(chang)(chang)率不(bu)合格直接大大縮短電(dian)(dian)線電(dian)(dian)纜(lan)的(de)工(gong)作(zuo)用壽命，而且在(zai)施工(gong)或在(zai)長(chang)(chang)時間通電(dian)(dian)且溫(wen)度(du)(du)較高的(de)環境中，極(ji)易出(chu)現絕(jue)緣(yuan)體斷裂，致使帶電(dian)(dian)導體裸露，發生能觸電(dian)(dian)式(shi)短路危險(xian)。其(qi)不(bu)合格的(de)主要(yao)原因是使用了(le)再生料生產(chan)，以降(jiang)低產(chan)品成本，二是不(bu)具(ju)備生產(chan)資格小型企業。

4、導(dao)(dao)體電(dian)(dian)阻(zu)(zu)不(bu)合(he)格(ge)(ge)的(de)(de)電(dian)(dian)線。導(dao)(dao)體電(dian)(dian)阻(zu)(zu)主要是考核電(dian)(dian)線電(dian)(dian)纜的(de)(de)導(dao)(dao)體材(cai)料以及截(jie)面(mian)是否符(fu)合(he)的(de)(de)重要指標(biao)。當導(dao)(dao)體電(dian)(dian)阻(zu)(zu)超標(biao)時(shi)，就增大了電(dian)(dian)流在(zai)線路上通過(guo)時(shi)的(de)(de)損耗，加(jia)(jia)劇了電(dian)(dian)線電(dian)(dian)纜的(de)(de)發(fa)熱。導(dao)(dao)體電(dian)(dian)阻(zu)(zu)不(bu)合(he)格(ge)(ge)的(de)(de)原(yuan)因，主要進企(qi)業為(wei)了降低成本，將(jiang)占(zhan)原(yuan)材(cai)料成本80%的(de)(de)銅(tong)材(cai)縮水，要么降低導(dao)(dao)體的(de)(de)截(jie)面(mian)積，要么使(shi)用含雜(za)質過(guo)高的(de)(de)再(zai)生銅(tong)，這樣致(zhi)使(shi)電(dian)(dian)線電(dian)(dian)纜的(de)(de)導(dao)(dao)體電(dian)(dian)阻(zu)(zu)嚴重超標(biao)，在(zai)使(shi)用過(guo)程中除易引發(fa)火(huo)災，還會加(jia)(jia)速包覆在(zai)電(dian)(dian)線外的(de)(de)絕緣層的(de)(de)老化。

在購買電線(xian)電纜的過(guo)程中，消費者(zhe)應注意以下幾(ji)個事

第一、要觀察電(dian)線(xian)的(de)外觀。合格產(chan)品的(de)絕(jue)緣（護套）層(ceng)柔(rou)軟、有韌性和(he)伸縮性、表面層(ceng)緊密、光滑、無粗糙感。如果包裹電(dian)線(xian)的(de)塑料(liao)很容(rong)易被剝去，則存(cun)在塑料(liao)強(qiang)度不夠的(de)問題。

第二、要(yao)看電線的截面。合格產品的銅芯或鋁(lv)芯表(biao)(biao)面應該具(ju)有(you)金屬(shu)光澤(ze)，表(biao)(biao)面發黑的銅或表(biao)(biao)面發白的鋁(lv)說明已被氧化(hua)。

第三(san)、在購買(mai)電(dian)線(xian)時應注意查看質(zhi)量合格證書(shu)。如果電(dian)線(xian)的(de)質(zhi)量合格，那么其電(dian)線(xian)質(zhi)量應該也受過(guo)檢驗，不會有太大的(de)問題。
