不合(he)格電線電纜的危害

電(dian)(dian)線電(dian)(dian)纜(lan)是用于傳輸(shu)電(dian)(dian)力(li)、傳輸(shu)信息(xi)和(he)實現電(dian)(dian)磁能量(liang)轉換的一(yi)大(da)類電(dian)(dian)工產(chan)品。在抽查過程中，發現了大(da)量(liang)的不合格(ge)產(chan)品，這些(xie)劣質(zhi)產(chan)品給電(dian)(dian)力(li)系統正常運行埋下(xia)諸多隱(yin)患。

1、標(biao)(biao)志不(bu)合(he)格的(de)電(dian)(dian)線(xian)電(dian)(dian)纜。標(biao)(biao)志是電(dian)(dian)線(xian)電(dian)(dian)纜使用識(shi)別產品(pin)(pin)基本信息的(de)主要途徑，根(gen)據(ju)標(biao)(biao)準(zhun)規(gui)定(ding)標(biao)(biao)志的(de)主要內(nei)容是：產品(pin)(pin)型(xing)號(hao)(hao)、規(gui)格、標(biao)(biao)準(zhun)號(hao)(hao)、廠名、產地等在一定(ding)的(de)標(biao)(biao)示(shi)間距內(nei)，當標(biao)(biao)志不(bu)合(he)格時(shi)，會(hui)造成施工人員識(shi)別錯誤，嚴重時(shi)會(hui)引發(fa)電(dian)(dian)氣事故。

2、結構尺(chi)寸不合格的電(dian)線(xian)(xian)(xian)電(dian)纜(lan)(lan)。結構尺(chi)寸的主要問題是護套厚(hou)度(du)(du)，絕(jue)緣厚(hou)度(du)(du)，當電(dian)纜(lan)(lan)的護套和絕(jue)緣厚(hou)度(du)(du)不達(da)標(biao)時(shi)，致(zhi)使(shi)電(dian)線(xian)(xian)(xian)電(dian)纜(lan)(lan)耐電(dian)氣(qi)強度(du)(du)會嚴重降(jiang)低，導致(zhi)電(dian)線(xian)(xian)(xian)電(dian)纜(lan)(lan)的使(shi)用(yong)壽命縮短，嚴重時(shi)可導致(zhi)電(dian)線(xian)(xian)(xian)電(dian)纜(lan)(lan)被(bei)擊穿，絕(jue)緣（護套）層(ceng)起(qi)不到正常保(bao)護作用(yong)，從(cong)而(er)發生電(dian)氣(qi)短路(lu)和火災等現象。

3、護(hu)套(tao)式(shi)絕(jue)緣老化前的抗(kang)(kang)張(zhang)強度、伸(shen)長率合格(ge)(ge)(ge)的電(dian)(dian)線(xian)電(dian)(dian)纜。絕(jue)緣護(hu)套(tao)老化前的抗(kang)(kang)張(zhang)強度、伸(shen)長率不合格(ge)(ge)(ge)直接大大縮短電(dian)(dian)線(xian)電(dian)(dian)纜的工(gong)作用壽命，而且(qie)在施工(gong)或在長時間通電(dian)(dian)且(qie)溫度較(jiao)高(gao)的環境中，極易出現絕(jue)緣體斷(duan)裂，致使帶(dai)電(dian)(dian)導(dao)體裸露，發生(sheng)能觸電(dian)(dian)式(shi)短路危險。其不合格(ge)(ge)(ge)的主(zhu)要原因是(shi)使用了(le)再生(sheng)料(liao)生(sheng)產(chan)，以(yi)降低產(chan)品成本，二(er)是(shi)不具(ju)備生(sheng)產(chan)資格(ge)(ge)(ge)小型企業(ye)。

4、導體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)不(bu)合(he)(he)格的(de)電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)。導體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)主(zhu)要(yao)是(shi)考核電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)導體(ti)材(cai)(cai)料以及(ji)截(jie)(jie)面(mian)是(shi)否符合(he)(he)的(de)重要(yao)指標。當導體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)超標時(shi)，就(jiu)增大了(le)電(dian)(dian)(dian)(dian)(dian)(dian)流在(zai)(zai)線(xian)路上通過時(shi)的(de)損耗(hao)，加劇(ju)了(le)電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)發熱。導體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)不(bu)合(he)(he)格的(de)原(yuan)因(yin)，主(zhu)要(yao)進企(qi)業為了(le)降(jiang)低成(cheng)本，將占(zhan)原(yuan)材(cai)(cai)料成(cheng)本80%的(de)銅(tong)材(cai)(cai)縮水，要(yao)么降(jiang)低導體(ti)的(de)截(jie)(jie)面(mian)積，要(yao)么使(shi)用(yong)含雜質過高的(de)再生(sheng)銅(tong)，這(zhe)樣致(zhi)使(shi)電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)的(de)導體(ti)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)(zu)嚴重超標，在(zai)(zai)使(shi)用(yong)過程中(zhong)除易引(yin)發火災，還會加速(su)包(bao)覆在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)(dian)線(xian)外(wai)的(de)絕緣層(ceng)的(de)老化。

在購買電線(xian)電纜的(de)過程中，消費者應注意以下(xia)幾個事

第一、要觀(guan)察電線(xian)的外觀(guan)。合格產品的絕(jue)緣（護套）層柔軟、有韌性和伸(shen)縮性、表(biao)面層緊密、光滑、無粗糙感。如果包裹電線(xian)的塑料很容易被(bei)剝去，則(ze)存在塑料強(qiang)度不夠(gou)的問題。

第二、要看電(dian)線的截(jie)面(mian)。合格(ge)產品的銅芯(xin)或鋁芯(xin)表(biao)(biao)面(mian)應(ying)該具有(you)金屬光澤，表(biao)(biao)面(mian)發黑的銅或表(biao)(biao)面(mian)發白的鋁說明已被氧化。

第三、在購買電線(xian)(xian)時應(ying)注意(yi)查看質量合(he)格證(zheng)書。如果(guo)電線(xian)(xian)的質量合(he)格，那么其電線(xian)(xian)質量應(ying)該也受過檢(jian)驗，不會有太大的問題。
