不合格電線電纜的危害

電線電纜是用(yong)于(yu)傳輸電力、傳輸信息和實現電磁能量轉換的一大(da)類電工產品。在抽查過(guo)程中，發現了大(da)量的不合格產品，這些劣質產品給電力系統正常運(yun)行埋下諸多(duo)隱患。

1、標(biao)志(zhi)(zhi)不(bu)合(he)格的(de)電(dian)線(xian)電(dian)纜(lan)。標(biao)志(zhi)(zhi)是(shi)(shi)電(dian)線(xian)電(dian)纜(lan)使用識別產品基本(ben)信息(xi)的(de)主(zhu)要(yao)途徑，根據標(biao)準(zhun)(zhun)規(gui)定(ding)(ding)標(biao)志(zhi)(zhi)的(de)主(zhu)要(yao)內容是(shi)(shi)：產品型(xing)號、規(gui)格、標(biao)準(zhun)(zhun)號、廠名、產地等(deng)在一定(ding)(ding)的(de)標(biao)示(shi)間距(ju)內，當標(biao)志(zhi)(zhi)不(bu)合(he)格時(shi)，會造成(cheng)施(shi)工人(ren)員識別錯誤，嚴重時(shi)會引發電(dian)氣事(shi)故。

2、結構(gou)尺(chi)寸不(bu)合格的電(dian)(dian)線(xian)電(dian)(dian)纜。結構(gou)尺(chi)寸的主要問題(ti)是護(hu)(hu)套厚度(du)，絕緣(yuan)厚度(du)，當電(dian)(dian)纜的護(hu)(hu)套和(he)絕緣(yuan)厚度(du)不(bu)達標(biao)時，致使電(dian)(dian)線(xian)電(dian)(dian)纜耐電(dian)(dian)氣(qi)強度(du)會(hui)嚴重降低，導(dao)致電(dian)(dian)線(xian)電(dian)(dian)纜的使用壽命縮短(duan)，嚴重時可導(dao)致電(dian)(dian)線(xian)電(dian)(dian)纜被(bei)擊穿，絕緣(yuan)（護(hu)(hu)套）層起不(bu)到正常保護(hu)(hu)作用，從而發(fa)生電(dian)(dian)氣(qi)短(duan)路和(he)火(huo)災等現象。

3、護套式絕(jue)(jue)緣(yuan)(yuan)老(lao)(lao)化(hua)前的抗張(zhang)強(qiang)度(du)、伸長(chang)(chang)率(lv)合(he)格(ge)(ge)的電(dian)(dian)線電(dian)(dian)纜(lan)。絕(jue)(jue)緣(yuan)(yuan)護套老(lao)(lao)化(hua)前的抗張(zhang)強(qiang)度(du)、伸長(chang)(chang)率(lv)不(bu)(bu)(bu)合(he)格(ge)(ge)直接大大縮(suo)短電(dian)(dian)線電(dian)(dian)纜(lan)的工作(zuo)用壽(shou)命，而且(qie)(qie)在施工或在長(chang)(chang)時間通電(dian)(dian)且(qie)(qie)溫(wen)度(du)較(jiao)高的環境中，極易出現(xian)絕(jue)(jue)緣(yuan)(yuan)體斷(duan)裂，致使帶電(dian)(dian)導體裸露，發生(sheng)能觸電(dian)(dian)式短路危險。其不(bu)(bu)(bu)合(he)格(ge)(ge)的主要(yao)原因是使用了(le)再(zai)生(sheng)料生(sheng)產，以(yi)降低產品成(cheng)本，二是不(bu)(bu)(bu)具(ju)備生(sheng)產資格(ge)(ge)小型(xing)企業。

4、導(dao)(dao)(dao)體電(dian)(dian)(dian)(dian)(dian)阻(zu)不合(he)格(ge)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)線。導(dao)(dao)(dao)體電(dian)(dian)(dian)(dian)(dian)阻(zu)主(zhu)要(yao)(yao)是考核電(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)纜(lan)的(de)(de)(de)(de)(de)導(dao)(dao)(dao)體材料以(yi)及截面是否符合(he)的(de)(de)(de)(de)(de)重要(yao)(yao)指標。當導(dao)(dao)(dao)體電(dian)(dian)(dian)(dian)(dian)阻(zu)超(chao)標時，就增大(da)了電(dian)(dian)(dian)(dian)(dian)流在(zai)線路上通過(guo)(guo)時的(de)(de)(de)(de)(de)損耗，加劇了電(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)纜(lan)的(de)(de)(de)(de)(de)發熱。導(dao)(dao)(dao)體電(dian)(dian)(dian)(dian)(dian)阻(zu)不合(he)格(ge)的(de)(de)(de)(de)(de)原(yuan)因，主(zhu)要(yao)(yao)進企業為(wei)了降低成本，將占原(yuan)材料成本80%的(de)(de)(de)(de)(de)銅(tong)材縮水，要(yao)(yao)么降低導(dao)(dao)(dao)體的(de)(de)(de)(de)(de)截面積，要(yao)(yao)么使用含(han)雜質過(guo)(guo)高的(de)(de)(de)(de)(de)再生銅(tong)，這樣致使電(dian)(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)(dian)纜(lan)的(de)(de)(de)(de)(de)導(dao)(dao)(dao)體電(dian)(dian)(dian)(dian)(dian)阻(zu)嚴重超(chao)標，在(zai)使用過(guo)(guo)程中除(chu)易引發火災，還會加速包覆在(zai)電(dian)(dian)(dian)(dian)(dian)線外的(de)(de)(de)(de)(de)絕(jue)緣層的(de)(de)(de)(de)(de)老(lao)化(hua)。

在購買電線電纜(lan)的過程(cheng)中，消費者(zhe)應(ying)注意(yi)以(yi)下幾(ji)個事

第一、要觀(guan)察電(dian)線的外觀(guan)。合格(ge)產品(pin)的絕緣（護套）層柔軟、有韌性(xing)和(he)伸縮性(xing)、表面層緊(jin)密、光滑、無粗糙感(gan)。如果包裹(guo)電(dian)線的塑(su)料(liao)很(hen)容易被剝去，則存在塑(su)料(liao)強度不夠的問題。

第二、要看(kan)電線的截面。合格產品(pin)的銅芯(xin)或鋁芯(xin)表面應該具有(you)金屬光澤，表面發黑的銅或表面發白(bai)的鋁說明已(yi)被氧化。

第三(san)、在(zai)購買電線時應注(zhu)意查(cha)看質量合格證(zheng)書。如果電線的質量合格，那么其電線質量應該也受過檢驗，不(bu)會(hui)有太大的問題。
