性能區別
The performance difference between
重慶電力電纜在電力系統主干線中用以傳輸和分配大功能電能,重慶控制電纜從電力系統的配電點把電能直接傳輸到各種用電設備器具的電源連接線路。電力電纜的額定電壓一般為0.6/1kV及以上,控制電纜主要為450/750V。同樣規格的電力電纜和控制電纜在生產時,重慶電力電纜的絕緣和護套厚度比控制電纜厚。
(一)控制電纜屬于電器裝備用電纜,和重慶電力電纜是電纜五大類中的2個。
(a) control cable which belongs to the electric appliance equipment cable, and Chongqing power cable is five kinds of cable 2.
(二)控制電纜的標準是9330,電力電纜的標準是GB12706。
(two) 9330 is the control cable, power cable is the standard GB12706.
(三)控制電纜的絕緣線芯的顏色一般都是黑色印白字、還有電力電纜低壓一般都是分色的。
(three) control cable wire core color is generally white, black printing and power cable is usually color separation voltage.
(四)控制電纜的截面一般都不會超過10平方,電力電纜主要是輸送電力的,一般都是大截面。www.cqqldl.com
(four) section of control cable are generally not more than 10 square meters, power cable is mainly for power, are generally large cross section. Www.cqqldl.com
由于以上大家講到的原因,電力電纜的規格一般可以較大,大到500平方(常規廠家能生產的范圍),再大的截面一般能做的廠家就相對少了,而控制電纜的截面一般較小,*大一般不超過10平方。

從電纜芯數上講,重慶電力電纜根據電網要求,*多一般為5芯,而控制電纜傳輸控制信號用,芯數較多,根據標準來講多的有61芯,但也可以根據用戶要求生產了。
From the cable core number sense, Chongqing power cable according to the grid requirements, most commonly 5 core, while the control cable transmission control signal, core number more, according to the standards of the 61 core, but also can according to customer requirements. |
