不(bu)合格電(dian)線電(dian)纜的危(wei)害(hai)

電(dian)(dian)線電(dian)(dian)纜(lan)是用于傳(chuan)輸電(dian)(dian)力、傳(chuan)輸信息和實現(xian)電(dian)(dian)磁能量轉換的(de)一大類電(dian)(dian)工產(chan)(chan)品。在(zai)抽查(cha)過程中(zhong)，發現(xian)了大量的(de)不合格產(chan)(chan)品，這些(xie)劣質產(chan)(chan)品給電(dian)(dian)力系統(tong)正常運(yun)行(xing)埋(mai)下諸(zhu)多隱患。

1、標(biao)志(zhi)(zhi)不(bu)合(he)格的(de)(de)(de)電(dian)線電(dian)纜(lan)(lan)。標(biao)志(zhi)(zhi)是電(dian)線電(dian)纜(lan)(lan)使用識別產(chan)品(pin)基(ji)本信息的(de)(de)(de)主(zhu)要途徑，根據(ju)標(biao)準(zhun)規(gui)定標(biao)志(zhi)(zhi)的(de)(de)(de)主(zhu)要內容是：產(chan)品(pin)型(xing)號、規(gui)格、標(biao)準(zhun)號、廠(chang)名(ming)、產(chan)地等在(zai)一定的(de)(de)(de)標(biao)示間距內，當標(biao)志(zhi)(zhi)不(bu)合(he)格時，會造(zao)成施工人員(yuan)識別錯(cuo)誤(wu)，嚴重(zhong)時會引發電(dian)氣(qi)事故。

2、結(jie)構尺寸(cun)不合格的(de)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)。結(jie)構尺寸(cun)的(de)主要(yao)問題是護(hu)套(tao)厚(hou)度(du)，絕(jue)緣厚(hou)度(du)，當(dang)電(dian)(dian)(dian)纜(lan)的(de)護(hu)套(tao)和絕(jue)緣厚(hou)度(du)不達標時(shi)，致使電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)耐(nai)電(dian)(dian)(dian)氣強度(du)會嚴(yan)重(zhong)降低，導致電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)的(de)使用壽命縮短，嚴(yan)重(zhong)時(shi)可導致電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)被擊穿，絕(jue)緣（護(hu)套(tao)）層起不到(dao)正常保護(hu)作用，從而發生(sheng)電(dian)(dian)(dian)氣短路和火(huo)災等現象(xiang)。

3、護套式(shi)絕緣(yuan)老化前的抗(kang)張強度(du)、伸長率合(he)格(ge)(ge)的電(dian)線電(dian)纜(lan)。絕緣(yuan)護套老化前的抗(kang)張強度(du)、伸長率不合(he)格(ge)(ge)直(zhi)接大(da)大(da)縮短(duan)電(dian)線電(dian)纜(lan)的工(gong)作用(yong)壽(shou)命(ming)，而且在施(shi)工(gong)或在長時(shi)間通電(dian)且溫度(du)較高的環境中，極易出(chu)現絕緣(yuan)體斷裂，致使帶(dai)電(dian)導體裸露，發生(sheng)(sheng)能觸電(dian)式(shi)短(duan)路危險。其不合(he)格(ge)(ge)的主要原因是(shi)使用(yong)了再生(sheng)(sheng)料生(sheng)(sheng)產(chan)，以降(jiang)低產(chan)品成本，二是(shi)不具備生(sheng)(sheng)產(chan)資(zi)格(ge)(ge)小型企業。

4、導(dao)體(ti)電(dian)阻不(bu)合格的(de)(de)(de)電(dian)線。導(dao)體(ti)電(dian)阻主要(yao)(yao)是考核(he)電(dian)線電(dian)纜(lan)(lan)的(de)(de)(de)導(dao)體(ti)材(cai)料以及(ji)截面(mian)是否(fou)符合的(de)(de)(de)重(zhong)要(yao)(yao)指(zhi)標(biao)。當導(dao)體(ti)電(dian)阻超(chao)標(biao)時(shi)(shi)，就增大(da)了(le)電(dian)流(liu)在(zai)線路上通過時(shi)(shi)的(de)(de)(de)損耗，加劇了(le)電(dian)線電(dian)纜(lan)(lan)的(de)(de)(de)發(fa)熱。導(dao)體(ti)電(dian)阻不(bu)合格的(de)(de)(de)原因(yin)，主要(yao)(yao)進(jin)企業為了(le)降低(di)成本(ben)，將占原材(cai)料成本(ben)80%的(de)(de)(de)銅材(cai)縮水，要(yao)(yao)么降低(di)導(dao)體(ti)的(de)(de)(de)截面(mian)積，要(yao)(yao)么使(shi)(shi)用含(han)雜質過高的(de)(de)(de)再生銅，這樣致使(shi)(shi)電(dian)線電(dian)纜(lan)(lan)的(de)(de)(de)導(dao)體(ti)電(dian)阻嚴(yan)重(zhong)超(chao)標(biao)，在(zai)使(shi)(shi)用過程中除易引(yin)發(fa)火災，還會加速(su)包(bao)覆(fu)在(zai)電(dian)線外的(de)(de)(de)絕緣層的(de)(de)(de)老化。

在購買電線電纜的過程中，消費者應注意以下幾個事

第一、要觀察電線的(de)外觀。合格產(chan)品的(de)絕緣(yuan)（護套）層柔軟、有韌性和(he)伸縮(suo)性、表(biao)面層緊密、光滑、無(wu)粗糙感。如(ru)果包裹電線的(de)塑料很(hen)容易被剝去，則存在塑料強度不夠的(de)問(wen)題。

第二(er)、要看電(dian)線的截面。合格產品的銅芯(xin)或(huo)鋁(lv)芯(xin)表(biao)面應該具有金(jin)屬光(guang)澤，表(biao)面發黑的銅或(huo)表(biao)面發白的鋁(lv)說明已被(bei)氧化。

第三、在購買電(dian)線時應(ying)注(zhu)意查看質量合格證書。如果電(dian)線的(de)(de)質量合格，那么其電(dian)線質量應(ying)該也受過檢驗，不會有太大的(de)(de)問題。
