不合格電(dian)線電(dian)纜的危(wei)害(hai)

電(dian)線電(dian)纜是用于傳輸電(dian)力、傳輸信息和實現電(dian)磁能量轉換的一大(da)類電(dian)工產品。在抽查過程(cheng)中，發(fa)現了大(da)量的不合格產品，這(zhe)些(xie)劣質產品給(gei)電(dian)力系統正常運(yun)行埋下諸多(duo)隱患。

1、標(biao)志不合格(ge)的(de)電(dian)線(xian)電(dian)纜。標(biao)志是電(dian)線(xian)電(dian)纜使用識(shi)別產品(pin)基本信(xin)息的(de)主要途(tu)徑(jing)，根據標(biao)準規(gui)定標(biao)志的(de)主要內容是：產品(pin)型號、規(gui)格(ge)、標(biao)準號、廠名、產地等在一定的(de)標(biao)示間(jian)距(ju)內，當標(biao)志不合格(ge)時(shi)，會造成施工人(ren)員識(shi)別錯(cuo)誤，嚴重時(shi)會引發(fa)電(dian)氣事故(gu)。

2、結構(gou)尺(chi)寸不(bu)合格的電線電纜(lan)(lan)。結構(gou)尺(chi)寸的主要問題是護套(tao)厚(hou)度(du)(du)，絕緣(yuan)厚(hou)度(du)(du)，當(dang)電纜(lan)(lan)的護套(tao)和絕緣(yuan)厚(hou)度(du)(du)不(bu)達標(biao)時，致(zhi)使電線電纜(lan)(lan)耐電氣強度(du)(du)會(hui)嚴(yan)(yan)重降(jiang)低，導(dao)致(zhi)電線電纜(lan)(lan)的使用壽命縮短，嚴(yan)(yan)重時可導(dao)致(zhi)電線電纜(lan)(lan)被擊穿，絕緣(yuan)（護套(tao)）層(ceng)起不(bu)到正常保護作用，從而發生電氣短路和火災等現象。

3、護(hu)(hu)套式(shi)絕緣老(lao)化(hua)前的(de)(de)抗(kang)張(zhang)(zhang)強度、伸(shen)長(chang)率(lv)合(he)格(ge)(ge)(ge)的(de)(de)電(dian)(dian)線電(dian)(dian)纜(lan)。絕緣護(hu)(hu)套老(lao)化(hua)前的(de)(de)抗(kang)張(zhang)(zhang)強度、伸(shen)長(chang)率(lv)不(bu)合(he)格(ge)(ge)(ge)直接大(da)大(da)縮短(duan)電(dian)(dian)線電(dian)(dian)纜(lan)的(de)(de)工(gong)作(zuo)用壽命，而且在(zai)施工(gong)或在(zai)長(chang)時間通電(dian)(dian)且溫(wen)度較高的(de)(de)環境中(zhong)，極易出(chu)現絕緣體斷(duan)裂(lie)，致使帶電(dian)(dian)導體裸露(lu)，發(fa)生能觸電(dian)(dian)式(shi)短(duan)路危險(xian)。其不(bu)合(he)格(ge)(ge)(ge)的(de)(de)主要原因是使用了(le)再生料生產(chan)，以降低產(chan)品成本，二是不(bu)具備生產(chan)資(zi)格(ge)(ge)(ge)小型企業。

4、導(dao)(dao)(dao)(dao)體電(dian)(dian)(dian)阻(zu)不合格的(de)(de)(de)電(dian)(dian)(dian)線(xian)。導(dao)(dao)(dao)(dao)體電(dian)(dian)(dian)阻(zu)主(zhu)要是考核電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)的(de)(de)(de)導(dao)(dao)(dao)(dao)體材料以及截面是否符合的(de)(de)(de)重要指標(biao)。當導(dao)(dao)(dao)(dao)體電(dian)(dian)(dian)阻(zu)超標(biao)時，就增大(da)了(le)電(dian)(dian)(dian)流在(zai)線(xian)路上通過(guo)時的(de)(de)(de)損(sun)耗，加劇了(le)電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)的(de)(de)(de)發(fa)熱。導(dao)(dao)(dao)(dao)體電(dian)(dian)(dian)阻(zu)不合格的(de)(de)(de)原因，主(zhu)要進企業為了(le)降低成(cheng)本，將占原材料成(cheng)本80%的(de)(de)(de)銅材縮水，要么降低導(dao)(dao)(dao)(dao)體的(de)(de)(de)截面積，要么使用(yong)含(han)雜質(zhi)過(guo)高的(de)(de)(de)再生銅，這樣(yang)致使電(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)纜(lan)的(de)(de)(de)導(dao)(dao)(dao)(dao)體電(dian)(dian)(dian)阻(zu)嚴重超標(biao)，在(zai)使用(yong)過(guo)程中(zhong)除易引發(fa)火災(zai)，還會加速包覆在(zai)電(dian)(dian)(dian)線(xian)外(wai)的(de)(de)(de)絕(jue)緣層的(de)(de)(de)老化。

在購買電線(xian)電纜的(de)過程中，消費者應注意以下幾個事

第(di)一、要觀察電線的(de)外觀。合格(ge)產品(pin)的(de)絕緣（護套）層(ceng)柔軟、有韌性和伸縮(suo)性、表面(mian)層(ceng)緊密、光滑、無粗糙(cao)感。如果包裹(guo)電線的(de)塑(su)料很容易(yi)被剝去，則存(cun)在塑(su)料強度不夠的(de)問題。

第二、要(yao)看電線(xian)的(de)截面(mian)(mian)。合格產品的(de)銅芯(xin)或鋁(lv)(lv)芯(xin)表(biao)面(mian)(mian)應該具有金屬光澤，表(biao)面(mian)(mian)發黑的(de)銅或表(biao)面(mian)(mian)發白的(de)鋁(lv)(lv)說明已被氧化。

第三、在購買電線時(shi)應注意查看質量合格證書。如果電線的質量合格，那么其(qi)電線質量應該(gai)也受過檢驗，不會有(you)太大的問題。
