不合格電(dian)線(xian)電(dian)纜的危害

電線(xian)電纜是用于傳(chuan)輸(shu)電力、傳(chuan)輸(shu)信息和實現(xian)電磁(ci)能量(liang)轉(zhuan)換的一大(da)類電工產(chan)品(pin)。在抽查過程(cheng)中，發現(xian)了(le)大(da)量(liang)的不合格產(chan)品(pin)，這些劣質產(chan)品(pin)給電力系統正常運行埋下(xia)諸多隱患。

1、標志不合格(ge)的電(dian)(dian)線電(dian)(dian)纜。標志是電(dian)(dian)線電(dian)(dian)纜使用(yong)識(shi)別(bie)產(chan)品基(ji)本信息的主要(yao)(yao)途徑(jing)，根據標準(zhun)(zhun)規定(ding)標志的主要(yao)(yao)內容是：產(chan)品型號、規格(ge)、標準(zhun)(zhun)號、廠名、產(chan)地等在一定(ding)的標示間距內，當標志不合格(ge)時，會(hui)(hui)造成施工人(ren)員識(shi)別(bie)錯(cuo)誤(wu)，嚴重時會(hui)(hui)引(yin)發電(dian)(dian)氣(qi)事故。

2、結構尺(chi)(chi)寸(cun)不合格的電(dian)(dian)線(xian)(xian)電(dian)(dian)纜。結構尺(chi)(chi)寸(cun)的主要問題是(shi)護套厚度(du)，絕緣厚度(du)，當電(dian)(dian)纜的護套和(he)絕緣厚度(du)不達(da)標時，致(zhi)使(shi)電(dian)(dian)線(xian)(xian)電(dian)(dian)纜耐電(dian)(dian)氣強度(du)會嚴重降(jiang)低，導致(zhi)電(dian)(dian)線(xian)(xian)電(dian)(dian)纜的使(shi)用壽命(ming)縮短，嚴重時可導致(zhi)電(dian)(dian)線(xian)(xian)電(dian)(dian)纜被擊穿，絕緣（護套）層(ceng)起不到正(zheng)常保護作用，從而(er)發生電(dian)(dian)氣短路(lu)和(he)火災等(deng)現象。

3、護(hu)套式(shi)絕(jue)(jue)緣老化前(qian)的(de)(de)抗(kang)張(zhang)強度、伸長(chang)率合(he)(he)(he)格的(de)(de)電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜。絕(jue)(jue)緣護(hu)套老化前(qian)的(de)(de)抗(kang)張(zhang)強度、伸長(chang)率不合(he)(he)(he)格直接大大縮短電(dian)(dian)(dian)(dian)線電(dian)(dian)(dian)(dian)纜的(de)(de)工作用壽命(ming)，而且(qie)在施工或在長(chang)時間通電(dian)(dian)(dian)(dian)且(qie)溫度較高的(de)(de)環境中，極易出現絕(jue)(jue)緣體斷裂，致(zhi)使帶電(dian)(dian)(dian)(dian)導(dao)體裸露，發生(sheng)能觸電(dian)(dian)(dian)(dian)式(shi)短路危險。其不合(he)(he)(he)格的(de)(de)主要原因(yin)是(shi)使用了再生(sheng)料生(sheng)產，以降(jiang)低產品成本，二是(shi)不具備生(sheng)產資格小型企業。

4、導(dao)(dao)(dao)體(ti)(ti)電(dian)(dian)阻(zu)不合(he)格的(de)電(dian)(dian)線(xian)(xian)。導(dao)(dao)(dao)體(ti)(ti)電(dian)(dian)阻(zu)主要是考核電(dian)(dian)線(xian)(xian)電(dian)(dian)纜的(de)導(dao)(dao)(dao)體(ti)(ti)材(cai)料以及截(jie)面是否符合(he)的(de)重(zhong)要指標。當導(dao)(dao)(dao)體(ti)(ti)電(dian)(dian)阻(zu)超標時，就(jiu)增(zeng)大了(le)(le)電(dian)(dian)流在線(xian)(xian)路上(shang)通(tong)過時的(de)損耗，加劇了(le)(le)電(dian)(dian)線(xian)(xian)電(dian)(dian)纜的(de)發熱(re)。導(dao)(dao)(dao)體(ti)(ti)電(dian)(dian)阻(zu)不合(he)格的(de)原因，主要進企業為了(le)(le)降低成本，將占原材(cai)料成本80%的(de)銅材(cai)縮水(shui)，要么降低導(dao)(dao)(dao)體(ti)(ti)的(de)截(jie)面積，要么使(shi)用含雜質(zhi)過高的(de)再生銅，這(zhe)樣致使(shi)電(dian)(dian)線(xian)(xian)電(dian)(dian)纜的(de)導(dao)(dao)(dao)體(ti)(ti)電(dian)(dian)阻(zu)嚴重(zhong)超標，在使(shi)用過程(cheng)中(zhong)除易引(yin)發火災，還會加速包覆在電(dian)(dian)線(xian)(xian)外的(de)絕(jue)緣層的(de)老化。

在(zai)購買(mai)電(dian)線電(dian)纜的(de)過程中，消費者應注意以下幾個事

第(di)一、要觀(guan)察電線的外(wai)觀(guan)。合格產品(pin)的絕緣（護套）層柔軟、有韌性和伸縮性、表(biao)面層緊密、光滑、無粗糙感(gan)。如果包(bao)裹電線的塑料(liao)很容易(yi)被剝去，則存在塑料(liao)強(qiang)度(du)不夠的問題。

第二、要看(kan)電線的(de)(de)截面。合格產品的(de)(de)銅芯(xin)或鋁芯(xin)表(biao)面應該(gai)具有金(jin)屬光澤，表(biao)面發(fa)黑的(de)(de)銅或表(biao)面發(fa)白的(de)(de)鋁說明(ming)已被氧化。

第三、在購買電線(xian)(xian)時應(ying)注意查看(kan)質量(liang)(liang)合格證書。如果電線(xian)(xian)的質量(liang)(liang)合格，那(nei)么其電線(xian)(xian)質量(liang)(liang)應(ying)該(gai)也受過(guo)檢驗，不(bu)會有(you)太大的問題。
