不(bu)合(he)格電線電纜(lan)的危(wei)害

電(dian)(dian)線電(dian)(dian)纜是(shi)用于(yu)傳(chuan)輸電(dian)(dian)力(li)、傳(chuan)輸信息(xi)和實(shi)現電(dian)(dian)磁能量轉換的(de)一(yi)大類電(dian)(dian)工產品(pin)(pin)。在抽查過程(cheng)中，發(fa)現了大量的(de)不(bu)合格產品(pin)(pin)，這些劣質產品(pin)(pin)給電(dian)(dian)力(li)系統正常運行埋下諸多隱患。

1、標(biao)志(zhi)不(bu)合(he)(he)格(ge)的(de)電線(xian)電纜。標(biao)志(zhi)是電線(xian)電纜使用識別產品基(ji)本信(xin)息的(de)主(zhu)要途(tu)徑，根據標(biao)準(zhun)規(gui)定標(biao)志(zhi)的(de)主(zhu)要內(nei)(nei)容是：產品型號(hao)、規(gui)格(ge)、標(biao)準(zhun)號(hao)、廠名(ming)、產地等在(zai)一定的(de)標(biao)示間距內(nei)(nei)，當(dang)標(biao)志(zhi)不(bu)合(he)(he)格(ge)時，會(hui)造成施工人(ren)員識別錯誤，嚴重時會(hui)引發電氣事故(gu)。

2、結(jie)構尺寸不合格的(de)電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)。結(jie)構尺寸的(de)主要問題是護套(tao)厚(hou)(hou)度(du)，絕(jue)緣(yuan)厚(hou)(hou)度(du)，當(dang)電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)的(de)護套(tao)和絕(jue)緣(yuan)厚(hou)(hou)度(du)不達(da)標(biao)時，致使(shi)電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)耐電(dian)(dian)(dian)(dian)氣強度(du)會(hui)嚴重降低，導(dao)(dao)致電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)的(de)使(shi)用壽命縮短(duan)，嚴重時可導(dao)(dao)致電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)被擊穿(chuan)，絕(jue)緣(yuan)（護套(tao)）層起不到(dao)正常保護作(zuo)用，從而發生電(dian)(dian)(dian)(dian)氣短(duan)路和火災等現象。

3、護套式絕(jue)緣老(lao)化前(qian)的抗(kang)張強度(du)、伸長(chang)(chang)(chang)率合(he)(he)格(ge)的電線(xian)電纜(lan)(lan)。絕(jue)緣護套老(lao)化前(qian)的抗(kang)張強度(du)、伸長(chang)(chang)(chang)率不合(he)(he)格(ge)直(zhi)接大大縮短電線(xian)電纜(lan)(lan)的工作(zuo)用(yong)壽命，而且在(zai)(zai)施工或在(zai)(zai)長(chang)(chang)(chang)時間(jian)通電且溫度(du)較高的環境中，極易(yi)出現絕(jue)緣體斷裂，致使帶電導體裸露(lu)，發生能(neng)觸電式短路危險(xian)。其不合(he)(he)格(ge)的主要原因是使用(yong)了(le)再生料生產(chan)，以降低產(chan)品(pin)成本，二是不具備(bei)生產(chan)資格(ge)小型企業(ye)。

4、導體(ti)(ti)(ti)電(dian)(dian)阻(zu)不合格的(de)(de)(de)(de)電(dian)(dian)線(xian)。導體(ti)(ti)(ti)電(dian)(dian)阻(zu)主(zhu)要(yao)是(shi)考(kao)核電(dian)(dian)線(xian)電(dian)(dian)纜的(de)(de)(de)(de)導體(ti)(ti)(ti)材(cai)料(liao)以及(ji)截面是(shi)否符合的(de)(de)(de)(de)重要(yao)指標(biao)。當導體(ti)(ti)(ti)電(dian)(dian)阻(zu)超標(biao)時(shi)，就(jiu)增大了電(dian)(dian)流(liu)在(zai)線(xian)路上通過時(shi)的(de)(de)(de)(de)損耗(hao)，加(jia)劇了電(dian)(dian)線(xian)電(dian)(dian)纜的(de)(de)(de)(de)發(fa)熱。導體(ti)(ti)(ti)電(dian)(dian)阻(zu)不合格的(de)(de)(de)(de)原(yuan)因(yin)，主(zhu)要(yao)進企業為了降低成本，將占原(yuan)材(cai)料(liao)成本80%的(de)(de)(de)(de)銅(tong)材(cai)縮水，要(yao)么降低導體(ti)(ti)(ti)的(de)(de)(de)(de)截面積(ji)，要(yao)么使(shi)(shi)用含(han)雜(za)質過高的(de)(de)(de)(de)再(zai)生(sheng)銅(tong)，這樣致使(shi)(shi)電(dian)(dian)線(xian)電(dian)(dian)纜的(de)(de)(de)(de)導體(ti)(ti)(ti)電(dian)(dian)阻(zu)嚴重超標(biao)，在(zai)使(shi)(shi)用過程中除易引發(fa)火(huo)災，還(huan)會加(jia)速包覆(fu)在(zai)電(dian)(dian)線(xian)外(wai)的(de)(de)(de)(de)絕(jue)緣層的(de)(de)(de)(de)老化。

在購買電(dian)線(xian)電(dian)纜的過程中，消(xiao)費者應注意以(yi)下幾(ji)個事

第一、要(yao)觀察電(dian)(dian)線的外觀。合格(ge)產品的絕緣(yuan)（護套）層柔軟、有韌性和伸縮(suo)性、表面層緊密、光滑、無粗糙感(gan)。如果包裹電(dian)(dian)線的塑料(liao)很容易被剝去(qu)，則存在塑料(liao)強度不夠的問(wen)題(ti)。

第(di)二、要看電線的截(jie)面(mian)(mian)。合格產(chan)品的銅芯或(huo)鋁(lv)芯表(biao)面(mian)(mian)應該具有金屬(shu)光澤(ze)，表(biao)面(mian)(mian)發(fa)黑的銅或(huo)表(biao)面(mian)(mian)發(fa)白的鋁(lv)說明(ming)已被氧(yang)化。

第三、在(zai)購買(mai)電線時應(ying)(ying)注意(yi)查看(kan)質量合(he)格(ge)證(zheng)書。如果電線的質量合(he)格(ge)，那么其(qi)電線質量應(ying)(ying)該也受過檢(jian)驗，不會有太大的問(wen)題(ti)。
