不(bu)合格電(dian)線電(dian)纜的危害(hai)

電線電纜(lan)是(shi)用于傳(chuan)輸(shu)(shu)電力、傳(chuan)輸(shu)(shu)信息和實現電磁能量(liang)轉換的一大類電工(gong)產品(pin)。在抽(chou)查(cha)過程中，發現了大量(liang)的不合格(ge)產品(pin)，這些(xie)劣質產品(pin)給電力系統正常運(yun)行埋(mai)下諸多隱(yin)患。

1、標(biao)志不合格(ge)的電(dian)線(xian)電(dian)纜(lan)。標(biao)志是電(dian)線(xian)電(dian)纜(lan)使用識別(bie)產品基本信息的主(zhu)要途徑(jing)，根據標(biao)準(zhun)(zhun)規(gui)定標(biao)志的主(zhu)要內容(rong)是：產品型號、規(gui)格(ge)、標(biao)準(zhun)(zhun)號、廠(chang)名、產地等在一定的標(biao)示間距內，當(dang)標(biao)志不合格(ge)時(shi)，會造成施工人員識別(bie)錯誤，嚴重(zhong)時(shi)會引發電(dian)氣(qi)事故。

2、結(jie)構(gou)尺寸(cun)不(bu)合(he)格的(de)電(dian)(dian)線(xian)電(dian)(dian)纜。結(jie)構(gou)尺寸(cun)的(de)主(zhu)要問題是護套厚度，絕(jue)緣(yuan)厚度，當電(dian)(dian)纜的(de)護套和(he)絕(jue)緣(yuan)厚度不(bu)達標時，致(zhi)使電(dian)(dian)線(xian)電(dian)(dian)纜耐電(dian)(dian)氣(qi)強(qiang)度會嚴(yan)重降低(di)，導致(zhi)電(dian)(dian)線(xian)電(dian)(dian)纜的(de)使用壽(shou)命縮短(duan)，嚴(yan)重時可導致(zhi)電(dian)(dian)線(xian)電(dian)(dian)纜被擊穿，絕(jue)緣(yuan)（護套）層起不(bu)到正常保(bao)護作用，從(cong)而發生電(dian)(dian)氣(qi)短(duan)路和(he)火災(zai)等現象。

3、護(hu)(hu)套(tao)式絕緣老化前(qian)的(de)(de)(de)抗(kang)張強度(du)、伸長(chang)率合格(ge)(ge)(ge)(ge)的(de)(de)(de)電(dian)(dian)線電(dian)(dian)纜。絕緣護(hu)(hu)套(tao)老化前(qian)的(de)(de)(de)抗(kang)張強度(du)、伸長(chang)率不(bu)合格(ge)(ge)(ge)(ge)直接大大縮短電(dian)(dian)線電(dian)(dian)纜的(de)(de)(de)工作(zuo)用壽命，而且在施工或在長(chang)時間通(tong)電(dian)(dian)且溫度(du)較高的(de)(de)(de)環境中，極(ji)易出現絕緣體(ti)斷裂(lie)，致使帶電(dian)(dian)導體(ti)裸露，發生能觸電(dian)(dian)式短路危險。其不(bu)合格(ge)(ge)(ge)(ge)的(de)(de)(de)主要(yao)原因(yin)是使用了再(zai)生料生產，以降低(di)產品成本，二是不(bu)具(ju)備(bei)生產資(zi)格(ge)(ge)(ge)(ge)小(xiao)型(xing)企業。

4、導(dao)體(ti)電(dian)(dian)(dian)阻不(bu)合(he)(he)(he)格的(de)(de)(de)(de)電(dian)(dian)(dian)線。導(dao)體(ti)電(dian)(dian)(dian)阻主(zhu)要(yao)是考核(he)電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)(lan)的(de)(de)(de)(de)導(dao)體(ti)材(cai)料(liao)以及截(jie)面是否符合(he)(he)(he)的(de)(de)(de)(de)重要(yao)指標(biao)。當導(dao)體(ti)電(dian)(dian)(dian)阻超標(biao)時，就增大了電(dian)(dian)(dian)流在線路(lu)上通過時的(de)(de)(de)(de)損耗，加劇了電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)(lan)的(de)(de)(de)(de)發熱。導(dao)體(ti)電(dian)(dian)(dian)阻不(bu)合(he)(he)(he)格的(de)(de)(de)(de)原因(yin)，主(zhu)要(yao)進企業為了降(jiang)低成本，將占(zhan)原材(cai)料(liao)成本80%的(de)(de)(de)(de)銅材(cai)縮水，要(yao)么(me)降(jiang)低導(dao)體(ti)的(de)(de)(de)(de)截(jie)面積，要(yao)么(me)使用(yong)含雜質過高的(de)(de)(de)(de)再生銅，這樣致使電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)(lan)的(de)(de)(de)(de)導(dao)體(ti)電(dian)(dian)(dian)阻嚴重超標(biao)，在使用(yong)過程中(zhong)除(chu)易引發火(huo)災，還會加速包覆(fu)在電(dian)(dian)(dian)線外的(de)(de)(de)(de)絕(jue)緣層(ceng)的(de)(de)(de)(de)老化(hua)。

在(zai)購買電(dian)線電(dian)纜的過(guo)程中，消(xiao)費者應注意以(yi)下幾個事

第(di)一(yi)、要觀察電線(xian)的外觀。合格(ge)產品的絕緣(yuan)（護套）層柔軟、有韌性和(he)伸縮性、表(biao)面層緊密、光滑(hua)、無粗糙(cao)感。如果包裹電線(xian)的塑料(liao)很容易被剝去，則存在塑料(liao)強度不(bu)夠的問題。

第二、要(yao)看電線(xian)的截(jie)面(mian)(mian)。合(he)格(ge)產(chan)品的銅芯或(huo)(huo)鋁(lv)芯表(biao)面(mian)(mian)應該具有金屬光澤，表(biao)面(mian)(mian)發黑的銅或(huo)(huo)表(biao)面(mian)(mian)發白的鋁(lv)說(shuo)明已被氧化。

第(di)三(san)、在購買電(dian)線時應注意查看質(zhi)量合(he)格(ge)證書。如果電(dian)線的(de)(de)質(zhi)量合(he)格(ge)，那么其電(dian)線質(zhi)量應該也受過檢驗，不會有太大的(de)(de)問(wen)題(ti)。
