不合格(ge)電線(xian)電纜的危害

電(dian)線電(dian)纜是(shi)用于傳輸(shu)電(dian)力、傳輸(shu)信息和實現電(dian)磁能(neng)量轉(zhuan)換(huan)的(de)一(yi)大(da)(da)類電(dian)工產(chan)(chan)品(pin)。在(zai)抽查過程(cheng)中(zhong)，發現了大(da)(da)量的(de)不合格(ge)產(chan)(chan)品(pin)，這些(xie)劣質產(chan)(chan)品(pin)給電(dian)力系統正常運行埋下諸多隱(yin)患。

1、標(biao)志不合(he)(he)格的(de)電線電纜。標(biao)志是(shi)電線電纜使用識(shi)別產品基本(ben)信息的(de)主(zhu)(zhu)要途徑，根據標(biao)準(zhun)規(gui)定標(biao)志的(de)主(zhu)(zhu)要內容(rong)是(shi)：產品型號、規(gui)格、標(biao)準(zhun)號、廠名、產地等(deng)在一定的(de)標(biao)示間距內，當(dang)標(biao)志不合(he)(he)格時(shi)，會造成施工人員識(shi)別錯誤(wu)，嚴重時(shi)會引發電氣(qi)事故。

2、結(jie)構尺寸不合格的(de)電(dian)(dian)線(xian)電(dian)(dian)纜。結(jie)構尺寸的(de)主要問題是(shi)護套厚(hou)度(du)(du)，絕(jue)(jue)緣(yuan)厚(hou)度(du)(du)，當電(dian)(dian)纜的(de)護套和(he)絕(jue)(jue)緣(yuan)厚(hou)度(du)(du)不達標時，致使電(dian)(dian)線(xian)電(dian)(dian)纜耐電(dian)(dian)氣強度(du)(du)會嚴重(zhong)降低(di)，導致電(dian)(dian)線(xian)電(dian)(dian)纜的(de)使用(yong)壽命縮短，嚴重(zhong)時可導致電(dian)(dian)線(xian)電(dian)(dian)纜被擊穿，絕(jue)(jue)緣(yuan)（護套）層起不到正常保護作用(yong)，從而發生電(dian)(dian)氣短路和(he)火災(zai)等現象。

3、護套(tao)式(shi)絕緣老(lao)化前(qian)的(de)抗張(zhang)強度(du)、伸長(chang)率(lv)合(he)格(ge)的(de)電線(xian)電纜。絕緣護套(tao)老(lao)化前(qian)的(de)抗張(zhang)強度(du)、伸長(chang)率(lv)不(bu)合(he)格(ge)直接大(da)大(da)縮短電線(xian)電纜的(de)工作(zuo)用(yong)壽(shou)命，而且(qie)在(zai)施工或在(zai)長(chang)時間通電且(qie)溫度(du)較高的(de)環境中，極易出現絕緣體(ti)(ti)斷裂，致使帶電導體(ti)(ti)裸(luo)露，發生(sheng)(sheng)能觸(chu)電式(shi)短路危險(xian)。其不(bu)合(he)格(ge)的(de)主要(yao)原因是使用(yong)了再生(sheng)(sheng)料生(sheng)(sheng)產(chan)(chan)，以(yi)降低產(chan)(chan)品成(cheng)本，二是不(bu)具備生(sheng)(sheng)產(chan)(chan)資格(ge)小型企業。

4、導(dao)體(ti)(ti)(ti)電(dian)(dian)阻不合格(ge)的(de)(de)(de)(de)電(dian)(dian)線。導(dao)體(ti)(ti)(ti)電(dian)(dian)阻主要(yao)是考核電(dian)(dian)線電(dian)(dian)纜(lan)(lan)的(de)(de)(de)(de)導(dao)體(ti)(ti)(ti)材料以及截(jie)(jie)面是否符合的(de)(de)(de)(de)重要(yao)指標(biao)。當(dang)導(dao)體(ti)(ti)(ti)電(dian)(dian)阻超標(biao)時，就增大了電(dian)(dian)流(liu)在(zai)(zai)線路上(shang)通過(guo)(guo)時的(de)(de)(de)(de)損(sun)耗，加劇了電(dian)(dian)線電(dian)(dian)纜(lan)(lan)的(de)(de)(de)(de)發熱。導(dao)體(ti)(ti)(ti)電(dian)(dian)阻不合格(ge)的(de)(de)(de)(de)原因，主要(yao)進企業為了降(jiang)(jiang)低(di)成(cheng)本(ben)，將占(zhan)原材料成(cheng)本(ben)80%的(de)(de)(de)(de)銅材縮水，要(yao)么降(jiang)(jiang)低(di)導(dao)體(ti)(ti)(ti)的(de)(de)(de)(de)截(jie)(jie)面積，要(yao)么使(shi)用含雜質過(guo)(guo)高的(de)(de)(de)(de)再生銅，這(zhe)樣致使(shi)電(dian)(dian)線電(dian)(dian)纜(lan)(lan)的(de)(de)(de)(de)導(dao)體(ti)(ti)(ti)電(dian)(dian)阻嚴重超標(biao)，在(zai)(zai)使(shi)用過(guo)(guo)程中除易引發火(huo)災，還會加速包覆在(zai)(zai)電(dian)(dian)線外的(de)(de)(de)(de)絕緣層的(de)(de)(de)(de)老化。

在(zai)購買電(dian)(dian)線(xian)電(dian)(dian)纜的過程中，消(xiao)費者應注意以下幾個事(shi)

第一(yi)、要觀(guan)察電(dian)(dian)線的(de)外觀(guan)。合格產品(pin)的(de)絕緣（護套）層柔軟(ruan)、有(you)韌性(xing)和(he)伸縮(suo)性(xing)、表面層緊(jin)密、光滑、無粗糙感(gan)。如果包(bao)裹電(dian)(dian)線的(de)塑料很容易被剝去，則存在塑料強度不夠的(de)問(wen)題。

第二、要看電線的(de)(de)截面(mian)。合格(ge)產品的(de)(de)銅芯或(huo)鋁(lv)芯表(biao)(biao)(biao)面(mian)應(ying)該(gai)具有(you)金屬光澤，表(biao)(biao)(biao)面(mian)發黑(hei)的(de)(de)銅或(huo)表(biao)(biao)(biao)面(mian)發白的(de)(de)鋁(lv)說(shuo)明(ming)已(yi)被氧化。

第三(san)、在購買電(dian)線(xian)時應(ying)注意查(cha)看質(zhi)量合格(ge)證書。如果電(dian)線(xian)的(de)質(zhi)量合格(ge)，那么其(qi)電(dian)線(xian)質(zhi)量應(ying)該也(ye)受過檢驗，不會有(you)太大的(de)問題。
