性能區別

控(kong)制電(dian)(dian)(dian)(dian)(dian)纜(lan)具有(you)防潮(chao)、防腐和(he)防損傷等特點(dian),可(ke)以(yi)敷(fu)設在(zai)隧(sui)道或(huo)電(dian)(dian)(dian)(dian)(dian)纜(lan)溝內。電(dian)(dian)(dian)(dian)(dian)力(li)(li)電(dian)(dian)(dian)(dian)(dian)纜(lan)在(zai)電(dian)(dian)(dian)(dian)(dian)力(li)(li)系統主(zhu)干(gan)線(xian)中用以(yi)傳輸和(he)分配大功率電(dian)(dian)(dian)(dian)(dian)能，控(kong)制電(dian)(dian)(dian)(dian)(dian)纜(lan)從(cong)電(dian)(dian)(dian)(dian)(dian)力(li)(li)系統的(de)配電(dian)(dian)(dian)(dian)(dian)點(dian)把電(dian)(dian)(dian)(dian)(dian)能直接傳輸到各(ge)種用電(dian)(dian)(dian)(dian)(dian)設備(bei)器具的(de)電(dian)(dian)(dian)(dian)(dian)源連接線(xian)路。電(dian)(dian)(dian)(dian)(dian)力(li)(li)電(dian)(dian)(dian)(dian)(dian)纜(lan)的(de)額定電(dian)(dian)(dian)(dian)(dian)壓一般(ban)為(wei)0.6/1kV及以(yi)上(shang)，控(kong)制電(dian)(dian)(dian)(dian)(dian)纜(lan)主(zhu)要(yao)為(wei)450/750V。同樣規格的(de)電(dian)(dian)(dian)(dian)(dian)力(li)(li)電(dian)(dian)(dian)(dian)(dian)纜(lan)和(he)控(kong)制電(dian)(dian)(dian)(dian)(dian)纜(lan)在(zai)生產時(shi)，電(dian)(dian)(dian)(dian)(dian)力(li)(li)電(dian)(dian)(dian)(dian)(dian)纜(lan)的(de)絕緣和(he)護套厚(hou)度(du)比控(kong)制電(dian)(dian)(dian)(dian)(dian)纜(lan)厚(hou)。

(一(yi))控制電(dian)(dian)纜屬于電(dian)(dian)器裝(zhuang)備(bei)用電(dian)(dian)纜，和電(dian)(dian)力電(dian)(dian)纜是電(dian)(dian)纜五大(da)類中的(de)2個。

(二(er))控(kong)制電(dian)纜的標準(zhun)是9330，電(dian)力(li)電(dian)纜的標準(zhun)是GB12706。

(三)控(kong)制電(dian)纜(lan)的(de)絕緣線芯的(de)顏色(se)一般都(dou)(dou)是(shi)黑色(se)印白(bai)字、還有(you)電(dian)力(li)電(dian)纜(lan)低壓一般都(dou)(dou)是(shi)分色(se)的(de)。

(四(si))控制電纜(lan)的截面一般(ban)都不會超過10平方，電力電纜(lan)主(zhu)要是輸送電力的，一般(ban)都是大截面。

由于以(yi)上(shang)大(da)家(jia)講到的原(yuan)因(yin),電力電纜的規格一(yi)般(ban)可(ke)以(yi)較大(da)，大(da)到500平方(fang)(常(chang)規廠家(jia)能生產(chan)的范(fan)圍(wei))，再大(da)的截面一(yi)般(ban)能做的廠家(jia)就相對少了，而控制電纜的截面一(yi)般(ban)較小，最大(da)一(yi)般(ban)不超過10平方(fang)。

從電(dian)(dian)纜芯(xin)(xin)(xin)數(shu)上講(jiang),電(dian)(dian)力(li)電(dian)(dian)纜根據(ju)電(dian)(dian)網要求,最多一般為5芯(xin)(xin)(xin),而控制電(dian)(dian)纜傳(chuan)輸控制信號(hao)用(yong)(yong)，芯(xin)(xin)(xin)數(shu)較(jiao)多，根據(ju)標準來講(jiang)多的有61芯(xin)(xin)(xin)，但(dan)也可以(yi)根據(ju)用(yong)(yong)戶要求生產了(le)。
