什么是電線電纜

電(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)纜(lan)(lan)是(shi)指用(yong)于(yu)電(dian)(dian)(dian)(dian)力、電(dian)(dian)(dian)(dian)氣及(ji)相(xiang)關傳輸用(yong)途的(de)(de)(de)(de)材料(liao)。“電(dian)(dian)(dian)(dian)線(xian)”和“電(dian)(dian)(dian)(dian)纜(lan)(lan)”并沒(mei)(mei)有嚴格的(de)(de)(de)(de)界限。通常將芯數少(shao)、產(chan)(chan)品直(zhi)徑小、結(jie)構簡(jian)單的(de)(de)(de)(de)產(chan)(chan)品稱(cheng)為(wei)(wei)(wei)電(dian)(dian)(dian)(dian)線(xian)，沒(mei)(mei)有絕緣(yuan)的(de)(de)(de)(de)稱(cheng)為(wei)(wei)(wei)裸(luo)電(dian)(dian)(dian)(dian)線(xian)，其他的(de)(de)(de)(de)稱(cheng)為(wei)(wei)(wei)電(dian)(dian)(dian)(dian)纜(lan)(lan)；導體截(jie)面積較大(da)的(de)(de)(de)(de)（大(da)于(yu)6平(ping)方毫米(mi)）稱(cheng)為(wei)(wei)(wei)大(da)電(dian)(dian)(dian)(dian)纜(lan)(lan)，較小的(de)(de)(de)(de)（小于(yu)或等于(yu)6平(ping)方毫米(mi)）稱(cheng)為(wei)(wei)(wei)小電(dian)(dian)(dian)(dian)線(xian)又稱(cheng)為(wei)(wei)(wei)布電(dian)(dian)(dian)(dian)線(xian)。

電線電纜的區別

電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)(xian)電(dian)(dian)(dian)(dian)纜(lan) 電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)(xian)是用(yong)于承(cheng)載電(dian)(dian)(dian)(dian)流(liu)的(de)導電(dian)(dian)(dian)(dian)金屬線(xian)(xian)(xian)(xian)(xian)材,具有(you)實心(xin)(xin)、絞合(he)、箔片等多種形式(shi),電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)(xian)的(de)尺寸較小,結構簡單;而(er)電(dian)(dian)(dian)(dian)纜(lan)是有(you)一(yi)根或者多根相互絕緣(yuan)的(de)導電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)(xian)芯置于密封(feng)護(hu)套中構成的(de)絕緣(yuan)導體,它(ta)的(de)尺寸較大,結構也較為(wei)(wei)復(fu)雜。 電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)(xian)電(dian)(dian)(dian)(dian)纜(lan)區(qu)(qu)別二(er)電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)(xian)電(dian)(dian)(dian)(dian)纜(lan) 電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)(xian)電(dian)(dian)(dian)(dian)纜(lan)的(de)第二(er)個區(qu)(qu)別便是電(dian)(dian)(dian)(dian)線(xian)(xian)(xian)(xian)(xian)可(ke)作(zuo)為(wei)(wei)傳輸信心(xin)(xin)和電(dian)(dian)(dian)(dian)能,還能夠作(zuo)為(wei)(wei)電(dian)(dian)(dian)(dian)機(ji)、電(dian)(dian)(dian)(dian)器的(de)構件和連接線(xian)(xian)(xian)(xian)(xian)一(yi)般用(yong)銅、鋁等制作(zuo);而(er)電(dian)(dian)(dian)(dian)纜(lan)主要用(yong)作(zuo)通信和電(dian)(dian)(dian)(dian)力,因此電(dian)(dian)(dian)(dian)纜(lan)也被分為(wei)(wei)通信電(dian)(dian)(dian)(dian)纜(lan)、電(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)纜(lan)、控制電(dian)(dian)(dian)(dian)纜(lan)等。

電線電纜的種類

電(dian)(dian)(dian)線電(dian)(dian)(dian)纜(lan)(lan)主要包括裸電(dian)(dian)(dian)線、布電(dian)(dian)(dian)線及電(dian)(dian)(dian)氣設備(bei)用電(dian)(dian)(dian)力電(dian)(dian)(dian)纜(lan)(lan)、交(jiao)聯電(dian)(dian)(dian)纜(lan)(lan)與通信(xin)光纜(lan)(lan)。

電線電纜結構順序

電線(xian)電纜產品的(de)(de)結(jie)構(gou)元件(jian)，從內到(dao)外總體上(shang)可分(fen)(fen)為導線(xian)、絕緣(yuan)層、屏蔽和(he)護層這(zhe)四個主要結(jie)構(gou)組(zu)成部分(fen)(fen)以及填充元件(jian)和(he)承拉元件(jian)等。根(gen)據產品的(de)(de)使用(yong)要求和(he)應用(yong)場合，有的(de)(de)產品結(jie)構(gou)極(ji)為簡單(dan)。

電線電纜的故障

1、外力損(sun)傷(shang)(shang)。由近幾(ji)年的(de)(de)運行分析來看，尤其(qi)是在經濟(ji)高(gao)速發展中的(de)(de) 海浦東，現相當多(duo)的(de)(de)電(dian)(dian)(dian)纜(lan)(lan)故障都是由于(yu)機械損(sun)傷(shang)(shang)引起的(de)(de)；2、絕緣(yuan)受潮。這(zhe)種情況也(ye)很常見，一般(ban)發生在直(zhi)埋(mai)或(huo)排管里的(de)(de)電(dian)(dian)(dian)纜(lan)(lan)接(jie)(jie)頭處；3、化(hua)學腐蝕，電(dian)(dian)(dian)纜(lan)(lan)直(zhi)接(jie)(jie)埋(mai)在有酸堿作用(yong)的(de)(de)地(di)區，造成電(dian)(dian)(dian)纜(lan)(lan)的(de)(de)鎧(kai)裝、鉛皮或(huo)外護層被腐蝕，致使保護層失效，絕緣(yuan)降低，也(ye)會導致電(dian)(dian)(dian)纜(lan)(lan)故障；4、長期過負荷運行。5、電(dian)(dian)(dian)纜(lan)(lan)接(jie)(jie)頭故障；6、環境和溫度(du)；7、電(dian)(dian)(dian)纜(lan)(lan)本體的(de)(de)正常老化(hua)或(huo)自然災害等(deng)其(qi)他(ta)原因。
