不(bu)合格(ge)電(dian)線電(dian)纜的危害

電(dian)(dian)線電(dian)(dian)纜是用于傳(chuan)輸電(dian)(dian)力、傳(chuan)輸信息和實(shi)現(xian)電(dian)(dian)磁(ci)能量轉(zhuan)換的一大類電(dian)(dian)工(gong)產品(pin)。在(zai)抽查過程中(zhong)，發(fa)現(xian)了大量的不合(he)格產品(pin)，這(zhe)些(xie)劣質產品(pin)給電(dian)(dian)力系統正常(chang)運行埋下諸多隱(yin)患。

1、標志不合格(ge)的(de)(de)電(dian)(dian)線電(dian)(dian)纜。標志是電(dian)(dian)線電(dian)(dian)纜使用識(shi)別產(chan)品(pin)基(ji)本信息的(de)(de)主要(yao)途徑，根據標準規定標志的(de)(de)主要(yao)內容是：產(chan)品(pin)型(xing)號、規格(ge)、標準號、廠(chang)名、產(chan)地等(deng)在一定的(de)(de)標示間距內，當標志不合格(ge)時，會造成施工人員識(shi)別錯誤，嚴重時會引發電(dian)(dian)氣(qi)事故(gu)。

2、結(jie)構尺(chi)(chi)寸(cun)不合(he)格的(de)(de)電線(xian)電纜(lan)(lan)。結(jie)構尺(chi)(chi)寸(cun)的(de)(de)主要問題是護套厚(hou)(hou)度，絕(jue)緣(yuan)厚(hou)(hou)度，當電纜(lan)(lan)的(de)(de)護套和絕(jue)緣(yuan)厚(hou)(hou)度不達標時(shi)，致(zhi)使(shi)電線(xian)電纜(lan)(lan)耐電氣(qi)強度會嚴重(zhong)降低，導致(zhi)電線(xian)電纜(lan)(lan)的(de)(de)使(shi)用壽命(ming)縮短(duan)，嚴重(zhong)時(shi)可導致(zhi)電線(xian)電纜(lan)(lan)被擊穿，絕(jue)緣(yuan)（護套）層起不到(dao)正常保護作用，從而發(fa)生電氣(qi)短(duan)路和火災等現象。

3、護套式絕(jue)緣老化前(qian)的抗(kang)張強度(du)、伸長(chang)率(lv)合格(ge)的電(dian)(dian)(dian)線電(dian)(dian)(dian)纜。絕(jue)緣護套老化前(qian)的抗(kang)張強度(du)、伸長(chang)率(lv)不(bu)(bu)合格(ge)直接大(da)大(da)縮短(duan)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜的工作用壽命，而且(qie)在施工或在長(chang)時間(jian)通電(dian)(dian)(dian)且(qie)溫度(du)較高的環境中，極易出現絕(jue)緣體斷裂，致使(shi)帶(dai)電(dian)(dian)(dian)導體裸露，發生(sheng)(sheng)能觸電(dian)(dian)(dian)式短(duan)路危險。其不(bu)(bu)合格(ge)的主要原因是(shi)使(shi)用了再生(sheng)(sheng)料(liao)生(sheng)(sheng)產，以降低產品成本(ben)，二是(shi)不(bu)(bu)具備生(sheng)(sheng)產資格(ge)小型企業(ye)。

4、導(dao)(dao)體(ti)電(dian)(dian)(dian)阻不合(he)格的(de)(de)(de)(de)電(dian)(dian)(dian)線(xian)(xian)。導(dao)(dao)體(ti)電(dian)(dian)(dian)阻主要是考核(he)電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜的(de)(de)(de)(de)導(dao)(dao)體(ti)材料以(yi)及(ji)截(jie)面是否(fou)符合(he)的(de)(de)(de)(de)重要指(zhi)標。當導(dao)(dao)體(ti)電(dian)(dian)(dian)阻超(chao)標時，就增(zeng)大了電(dian)(dian)(dian)流在線(xian)(xian)路上通過時的(de)(de)(de)(de)損耗，加(jia)劇了電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜的(de)(de)(de)(de)發熱。導(dao)(dao)體(ti)電(dian)(dian)(dian)阻不合(he)格的(de)(de)(de)(de)原因，主要進(jin)企業(ye)為了降低成本，將占原材料成本80%的(de)(de)(de)(de)銅(tong)材縮水，要么(me)降低導(dao)(dao)體(ti)的(de)(de)(de)(de)截(jie)面積，要么(me)使(shi)用含雜(za)質過高的(de)(de)(de)(de)再生銅(tong)，這樣(yang)致使(shi)電(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)纜的(de)(de)(de)(de)導(dao)(dao)體(ti)電(dian)(dian)(dian)阻嚴重超(chao)標，在使(shi)用過程中(zhong)除(chu)易引(yin)發火災，還會加(jia)速包(bao)覆在電(dian)(dian)(dian)線(xian)(xian)外的(de)(de)(de)(de)絕緣(yuan)層的(de)(de)(de)(de)老化。

在購買電線電纜的過程中，消費(fei)者應(ying)注(zhu)意以下幾(ji)個事

第一、要(yao)觀(guan)察電線的外觀(guan)。合格產品的絕緣（護(hu)套）層柔軟、有韌性和(he)伸縮性、表(biao)面層緊密、光滑、無粗糙感。如果包裹(guo)電線的塑(su)料很容易被剝去(qu)，則存在塑(su)料強度(du)不夠(gou)的問題(ti)。

第二(er)、要(yao)看電(dian)線的截面。合(he)格產品的銅(tong)芯(xin)或鋁(lv)芯(xin)表面應該具有(you)金屬光澤，表面發(fa)黑的銅(tong)或表面發(fa)白的鋁(lv)說(shuo)明已被氧化。

第三、在購買電線(xian)時(shi)應注意查看質(zhi)量(liang)(liang)合(he)格(ge)證書。如果電線(xian)的(de)(de)質(zhi)量(liang)(liang)合(he)格(ge)，那么其電線(xian)質(zhi)量(liang)(liang)應該也受(shou)過檢(jian)驗，不會有(you)太大的(de)(de)問(wen)題。
