用途不一樣罷了

　　電力電纜是0.6/1kv的 如VV，YJV

　　控制電纜是450/750v 的 如KVV，KVVP

　　一(yi)般(ban)電(dian)力電(dian)纜都在5芯以(yi)內 一(yi)般(ban)用于(yu)強(qiang)電(dian)

　　控制電纜芯比較多，有(you)時候客戶(hu)要求不(bu)一，一般到37芯的，但也(ye)有(you)更多芯的。

　　電力電纜和控制電纜有什么區別?

　　常用的電(dian)纜分類(lei)分為五(wu)大(da)類(lei)：

　　(一) 電線與裸內導(dao)體(ti)制品：指僅有(you)導(dao)體(ti)，而無絕緣層和(he)其它結構。如：銅、鋁及各種復合(he)金屬單線;各種結構的(de)架空傳輸用絞線、軟接線、型線和(he)型材等(deng)(deng)等(deng)(deng)。

　　(二) 電磁(ci)線：以繞(rao)組的形式(shi)在磁(ci)場(chang)中(zhong)切割(ge)磁(ci)力線感應產生電流(liu)，或(huo)通(tong)過以電流(liu)產生磁(ci)場(chang)作用的電線稱為(wei)電磁(ci)線。如(ru)漆包線、纖維繞(rao)包線、無機絕(jue)緣線等(deng)等(deng)。

　　(三) 電(dian)(dian)(dian)力(li)(li)(li)電(dian)(dian)(dian)纜：在電(dian)(dian)(dian)力(li)(li)(li)系統的主干線(xian)路(lu)中用以傳輸和分(fen)配(pei)大(da)功(gong)率(lv)電(dian)(dian)(dian)能的電(dian)(dian)(dian)線(xian)產品(pin)，稱為電(dian)(dian)(dian)力(li)(li)(li)電(dian)(dian)(dian)纜。如：各種電(dian)(dian)(dian)壓等(deng)級的塑力(li)(li)(li)纜、油浸紙(zhi)電(dian)(dian)(dian)纜和不滴流(liu)等(deng)等(deng)。

　　(四) 通(tong)(tong)信(xin)(xin)電(dian)(dian)纜(lan)：傳輸音(yin)頻(pin)和音(yin)頻(pin)以上各種(zhong)電(dian)(dian)訊信(xin)(xin)息用的電(dian)(dian)纜(lan)。如：市話電(dian)(dian)纜(lan)、長途對(dui)稱(cheng)通(tong)(tong)信(xin)(xin)電(dian)(dian)纜(lan)、同軸(zhou)通(tong)(tong)信(xin)(xin)電(dian)(dian)纜(lan)、電(dian)(dian)話設備(bei)用電(dian)(dian)纜(lan)和數(shu)據(ju)電(dian)(dian)纜(lan)等(deng)等(deng)。

　　(五(wu)) 電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)氣裝(zhuang)(zhuang)備(bei)(bei)用(yong)(yong)(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)：從電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)力系(xi)統的配電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)點把電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)能直(zhi)接傳送到各(ge)種用(yong)(yong)(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)設備(bei)(bei)、器具的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源連接用(yong)(yong)(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)。如(ru)：各(ge)種工農(nong)業裝(zhuang)(zhuang)備(bei)(bei)中(zhong)的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)氣連接和控(kong)制信號用(yong)(yong)(yong)(yong)的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)線(xian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)。這(zhe)類產(chan)品使用(yong)(yong)(yong)(yong)面廣、品種繁多(duo)，而(er)且大(da)多(duo)要結(jie)合所用(yong)(yong)(yong)(yong)裝(zhuang)(zhuang)備(bei)(bei)的特征和使用(yong)(yong)(yong)(yong)的環境條件(jian)來確定產(chan)品的結(jie)構、性能。因此(ci)除大(da)量的通用(yong)(yong)(yong)(yong)產(chan)品外，還有許多(duo)專(zhuan)用(yong)(yong)(yong)(yong)和特種產(chan)品。如(ru)：通用(yong)(yong)(yong)(yong)的絕緣電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)線(xian)、安(an)裝(zhuang)(zhuang)線(xian)、橡套軟電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)、控(kong)制電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)、信號電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)、飛機、汽車(che)(che)、拖拉機專(zhuan)用(yong)(yong)(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器引出線(xian)、機車(che)(che)車(che)(che)輛用(yong)(yong)(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)、無線(xian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)裝(zhuang)(zhuang)置用(yong)(yong)(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)線(xian)、礦用(yong)(yong)(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)、船用(yong)(yong)(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)、農(nong)用(yong)(yong)(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)、油礦及(ji)探測電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)、野外工作用(yong)(yong)(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)、各(ge)種高壓直(zhi)流裝(zhuang)(zhuang)備(bei)(bei)用(yong)(yong)(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)線(xian)、軟電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜(lan)(lan)(lan)等等。

　　電力(li)(li)電纜(lan)在電力(li)(li)系(xi)統主干線中用以傳(chuan)輸(shu)和分(fen)配大功能電能，控制(zhi)電纜(lan)從電力(li)(li)系(xi)統的(de)(de)配電點(dian)把電能直接傳(chuan)輸(shu)到各種用電設備器具的(de)(de)電源(yuan)連接線路。電力(li)(li)電纜(lan)的(de)(de)額定電壓(ya)一般為0.6/1kV及以上，控制(zhi)電纜(lan)主要(yao)為450/750V。同樣規格的(de)(de)電力(li)(li)電纜(lan)和控制(zhi)電纜(lan)在生產時，電力(li)(li)電纜(lan)的(de)(de)絕緣和護(hu)套厚度比控制(zhi)電纜(lan)厚。

　　首先，控(kong)制電(dian)纜屬于電(dian)器裝備用電(dian)纜，和電(dian)力電(dian)纜是電(dian)纜五大類中的(de)2個。

　　控制電(dian)纜的標準(zhun)是(shi)9330，電(dian)力電(dian)纜的標準(zhun)是(shi)GB12706

　　控制電纜(lan)的絕緣線芯的顏色一般都是(shi)黑色印白字(zi)、還有電力(li)電纜(lan)低壓一般都是(shi)分(fen)色的。

　　電力電纜和控制電纜有什么區別?

　　控(kong)制電(dian)纜(lan)的截面一般(ban)都不會超過10平方，電(dian)力電(dian)纜(lan)主要是輸送(song)電(dian)力的，一般(ban)都是大截面。

　　由于以(yi)上大(da)家講到的原因, 電(dian)力電(dian)纜的規格一般可以(yi)較大(da)，大(da)到500平方(常規廠家能生(sheng)產的范圍)，再大(da)的截(jie)面般能做的廠家就相對(dui)少了(le)，而控制電(dian)纜的截(jie)面一般較小，*大(da)一般不(bu)超過10平方。

　　從(cong)電(dian)(dian)纜(lan)芯(xin)數上(shang)講(jiang), 電(dian)(dian)力電(dian)(dian)纜(lan)根(gen)據(ju)電(dian)(dian)網(wang)要求,*多一般為(wei)5芯(xin),而控(kong)制電(dian)(dian)纜(lan)傳輸控(kong)制信號用，芯(xin)數較(jiao)多，根(gen)據(ju)標準來(lai)講(jiang)多的有61芯(xin)，但也(ye)可(ke)以根(gen)據(ju)用戶要求生產了(le)。
