不合格(ge)電(dian)線電(dian)纜的(de)危害

電線(xian)電纜是用(yong)于傳輸電力、傳輸信(xin)息和實現電磁能量轉(zhuan)換的(de)一大(da)類電工(gong)產(chan)品(pin)。在抽查過程中，發現了大(da)量的(de)不合格產(chan)品(pin)，這些(xie)劣質(zhi)產(chan)品(pin)給電力系統正常(chang)運行埋下諸多(duo)隱患(huan)。

1、標(biao)志(zhi)不合格的(de)(de)電(dian)線電(dian)纜(lan)。標(biao)志(zhi)是電(dian)線電(dian)纜(lan)使用(yong)識別(bie)產品(pin)基本信息的(de)(de)主要(yao)(yao)途徑(jing)，根(gen)據標(biao)準規定標(biao)志(zhi)的(de)(de)主要(yao)(yao)內容是：產品(pin)型號、規格、標(biao)準號、廠(chang)名、產地等在一定的(de)(de)標(biao)示間距內，當標(biao)志(zhi)不合格時(shi)，會造成施工人員(yuan)識別(bie)錯誤，嚴重時(shi)會引(yin)發電(dian)氣事故。

2、結(jie)(jie)構(gou)尺寸不合(he)格的(de)電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)。結(jie)(jie)構(gou)尺寸的(de)主(zhu)要(yao)問題是護(hu)套厚度(du)，絕(jue)緣厚度(du)，當電(dian)(dian)(dian)(dian)纜(lan)的(de)護(hu)套和絕(jue)緣厚度(du)不達標時，致(zhi)使(shi)電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)耐電(dian)(dian)(dian)(dian)氣強度(du)會嚴重降低，導致(zhi)電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)的(de)使(shi)用壽命縮(suo)短，嚴重時可導致(zhi)電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)被擊穿，絕(jue)緣（護(hu)套）層起不到(dao)正常保(bao)護(hu)作用，從而發(fa)生電(dian)(dian)(dian)(dian)氣短路和火災等現象。

3、護套式絕(jue)緣(yuan)老化前(qian)的(de)(de)(de)抗張強(qiang)度、伸(shen)長(chang)率合(he)格的(de)(de)(de)電(dian)線(xian)電(dian)纜(lan)。絕(jue)緣(yuan)護套老化前(qian)的(de)(de)(de)抗張強(qiang)度、伸(shen)長(chang)率不合(he)格直接大大縮短電(dian)線(xian)電(dian)纜(lan)的(de)(de)(de)工作用(yong)壽(shou)命，而且在施工或在長(chang)時(shi)間通(tong)電(dian)且溫度較高(gao)的(de)(de)(de)環境中，極易出現絕(jue)緣(yuan)體斷裂，致使帶電(dian)導體裸露，發生(sheng)(sheng)能觸電(dian)式短路危(wei)險(xian)。其不合(he)格的(de)(de)(de)主(zhu)要原因是使用(yong)了再(zai)生(sheng)(sheng)料生(sheng)(sheng)產，以降低產品成本，二(er)是不具備生(sheng)(sheng)產資(zi)格小型企業。

4、導(dao)體(ti)電(dian)(dian)(dian)(dian)(dian)阻不合格的(de)(de)電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)。導(dao)體(ti)電(dian)(dian)(dian)(dian)(dian)阻主要是(shi)考核(he)電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)纜的(de)(de)導(dao)體(ti)材(cai)(cai)料(liao)以及截(jie)面(mian)(mian)是(shi)否(fou)符合的(de)(de)重要指標。當導(dao)體(ti)電(dian)(dian)(dian)(dian)(dian)阻超標時，就增大了電(dian)(dian)(dian)(dian)(dian)流(liu)在線(xian)(xian)路(lu)上(shang)通(tong)過時的(de)(de)損耗，加(jia)(jia)劇了電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)纜的(de)(de)發(fa)熱。導(dao)體(ti)電(dian)(dian)(dian)(dian)(dian)阻不合格的(de)(de)原因，主要進(jin)企業為了降低成(cheng)本(ben)，將占原材(cai)(cai)料(liao)成(cheng)本(ben)80%的(de)(de)銅材(cai)(cai)縮水，要么(me)降低導(dao)體(ti)的(de)(de)截(jie)面(mian)(mian)積，要么(me)使用含雜質(zhi)過高的(de)(de)再生銅，這樣致使電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)電(dian)(dian)(dian)(dian)(dian)纜的(de)(de)導(dao)體(ti)電(dian)(dian)(dian)(dian)(dian)阻嚴重超標，在使用過程中除易引(yin)發(fa)火災，還會加(jia)(jia)速(su)包覆在電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)外(wai)的(de)(de)絕緣層的(de)(de)老化。

在購買電線電纜(lan)的過程中，消費者應(ying)注意以下幾個事(shi)

第一、要觀(guan)察電(dian)線的外觀(guan)。合格產品的絕緣（護套）層柔軟、有韌性(xing)和伸縮性(xing)、表面層緊密、光滑、無粗(cu)糙感。如果包裹電(dian)線的塑料(liao)很(hen)容(rong)易(yi)被(bei)剝去，則存在塑料(liao)強度不夠的問題。

第二、要看電線的(de)截(jie)面(mian)(mian)。合格產(chan)品的(de)銅芯或鋁芯表面(mian)(mian)應該具(ju)有(you)金屬光澤，表面(mian)(mian)發黑的(de)銅或表面(mian)(mian)發白的(de)鋁說明(ming)已(yi)被氧化。

第(di)三、在購(gou)買(mai)電(dian)線時應注意查看質量合(he)格(ge)證書。如果電(dian)線的(de)質量合(he)格(ge)，那么(me)其電(dian)線質量應該也受過檢(jian)驗，不會有太大的(de)問題。
