不合格電(dian)線電(dian)纜(lan)的(de)危害

電(dian)線電(dian)纜是(shi)用于傳輸電(dian)力(li)、傳輸信息和實現電(dian)磁能(neng)量轉換的一大(da)類(lei)電(dian)工產品(pin)。在(zai)抽查過程中，發現了大(da)量的不(bu)合(he)格(ge)產品(pin)，這些劣(lie)質產品(pin)給電(dian)力(li)系統正(zheng)常運(yun)行埋下諸多隱患(huan)。

1、標(biao)志(zhi)不合格(ge)(ge)的電(dian)線電(dian)纜(lan)。標(biao)志(zhi)是電(dian)線電(dian)纜(lan)使(shi)用識別(bie)(bie)產品基本信(xin)息(xi)的主要(yao)(yao)途徑(jing)，根據標(biao)準(zhun)規(gui)(gui)定標(biao)志(zhi)的主要(yao)(yao)內容是：產品型號(hao)、規(gui)(gui)格(ge)(ge)、標(biao)準(zhun)號(hao)、廠(chang)名、產地(di)等(deng)在一定的標(biao)示間距內，當標(biao)志(zhi)不合格(ge)(ge)時，會(hui)造成施工人員(yuan)識別(bie)(bie)錯誤，嚴重時會(hui)引(yin)發電(dian)氣(qi)事故。

2、結構尺寸不合格的電(dian)線(xian)電(dian)纜(lan)。結構尺寸的主要問(wen)題是護套厚(hou)(hou)度(du)(du)，絕(jue)緣厚(hou)(hou)度(du)(du)，當電(dian)纜(lan)的護套和絕(jue)緣厚(hou)(hou)度(du)(du)不達標時(shi)，致使電(dian)線(xian)電(dian)纜(lan)耐電(dian)氣(qi)強度(du)(du)會嚴重降低，導致電(dian)線(xian)電(dian)纜(lan)的使用壽命縮短，嚴重時(shi)可導致電(dian)線(xian)電(dian)纜(lan)被擊穿，絕(jue)緣（護套）層起(qi)不到(dao)正常保護作(zuo)用，從而發生電(dian)氣(qi)短路和火災(zai)等現象。

3、護(hu)(hu)套式(shi)絕(jue)緣老化前的(de)(de)抗張(zhang)強(qiang)度、伸(shen)長率合格(ge)的(de)(de)電線電纜(lan)。絕(jue)緣護(hu)(hu)套老化前的(de)(de)抗張(zhang)強(qiang)度、伸(shen)長率不(bu)合格(ge)直接大大縮短電線電纜(lan)的(de)(de)工作用壽命，而且在(zai)施工或在(zai)長時間通電且溫度較高的(de)(de)環(huan)境(jing)中，極易出現絕(jue)緣體(ti)斷(duan)裂，致使(shi)(shi)帶(dai)電導體(ti)裸露，發生能觸電式(shi)短路(lu)危(wei)險。其不(bu)合格(ge)的(de)(de)主要原因是(shi)使(shi)(shi)用了再生料生產，以降低產品成本，二是(shi)不(bu)具備生產資格(ge)小型企業。

4、導(dao)(dao)體(ti)(ti)(ti)電(dian)(dian)阻(zu)不合(he)格的電(dian)(dian)線。導(dao)(dao)體(ti)(ti)(ti)電(dian)(dian)阻(zu)主(zhu)(zhu)要是考核(he)電(dian)(dian)線電(dian)(dian)纜(lan)的導(dao)(dao)體(ti)(ti)(ti)材(cai)料(liao)以(yi)及截(jie)面(mian)是否(fou)符(fu)合(he)的重(zhong)要指標(biao)。當(dang)導(dao)(dao)體(ti)(ti)(ti)電(dian)(dian)阻(zu)超(chao)(chao)標(biao)時，就增大了(le)電(dian)(dian)流在(zai)線路上(shang)通過(guo)時的損耗(hao)，加(jia)劇(ju)了(le)電(dian)(dian)線電(dian)(dian)纜(lan)的發(fa)熱。導(dao)(dao)體(ti)(ti)(ti)電(dian)(dian)阻(zu)不合(he)格的原(yuan)因，主(zhu)(zhu)要進企(qi)業為(wei)了(le)降低成本，將占原(yuan)材(cai)料(liao)成本80%的銅材(cai)縮水，要么降低導(dao)(dao)體(ti)(ti)(ti)的截(jie)面(mian)積，要么使用含(han)雜質過(guo)高的再生銅，這樣致(zhi)使電(dian)(dian)線電(dian)(dian)纜(lan)的導(dao)(dao)體(ti)(ti)(ti)電(dian)(dian)阻(zu)嚴(yan)重(zhong)超(chao)(chao)標(biao)，在(zai)使用過(guo)程中(zhong)除易(yi)引發(fa)火災，還會加(jia)速包覆在(zai)電(dian)(dian)線外的絕緣層(ceng)的老化。

在購買電線(xian)電纜(lan)的過程中，消費者應(ying)注意(yi)以下幾(ji)個事

第一、要觀察電(dian)線(xian)(xian)的(de)外(wai)觀。合(he)格產品的(de)絕緣（護(hu)套(tao)）層柔軟、有(you)韌性(xing)(xing)和伸(shen)縮性(xing)(xing)、表面層緊密、光滑、無粗糙感。如果(guo)包(bao)裹電(dian)線(xian)(xian)的(de)塑料(liao)(liao)很容易被(bei)剝去，則(ze)存在塑料(liao)(liao)強度不(bu)夠的(de)問題。

第二、要(yao)看電線(xian)的(de)截(jie)面(mian)。合格產(chan)品(pin)的(de)銅芯或鋁(lv)芯表面(mian)應(ying)該具有(you)金(jin)屬光(guang)澤，表面(mian)發黑的(de)銅或表面(mian)發白的(de)鋁(lv)說明已被氧化。

第三(san)、在(zai)購買(mai)電(dian)(dian)線時(shi)應注意查看質量(liang)合格證(zheng)書。如果(guo)電(dian)(dian)線的(de)質量(liang)合格，那么其電(dian)(dian)線質量(liang)應該(gai)也(ye)受過檢(jian)驗，不(bu)會(hui)有太大的(de)問題(ti)。
