性能区别
The performance difference between
重庆电力电缆在电力系统主干线中用以传输和分配大功能电能，重庆控制电缆从电力系统的配电点把电能直接传输到各种用电设备器具的电源连接线路。电力电缆的额定电压一般为0.6/1kV及以上，控制电缆主要为450/750V。同样规格的电力电缆和控制电缆在生产时，重庆电力电缆的绝缘和护套厚度比控制电缆厚。
(一)控制电缆属于电器装备用电缆，和重庆电力电缆是电缆五大类中的2个。
(a) control cable which belongs to the electric appliance equipment cable, and Chongqing power cable is five kinds of cable 2.
(二)控制电缆的标准是9330，电力电缆的标准是GB12706。
(two) 9330 is the control cable, power cable is the standard GB12706.
(三)控制电缆的绝缘线芯的颜色一般都是黑色印白字、还有电力电缆低压一般都是分色的。
(three) control cable wire core color is generally white, black printing and power cable is usually color separation voltage.
(四)控制电缆的截面一般都不会超过10平方，电力电缆主要是输送电力的，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
由于以上大家讲到的原因,电力电缆的规格一般可以较大，大到500平方(常规厂家能生产的范围)，再大的截面一般能做的厂家就相对少了，而控制电缆的截面一般较小，*大一般不超过10平方。

从电缆芯数上讲,重庆电力电缆根据电网要求,*多一般为5芯,而控制电缆传输控制信号用，芯数较多，根据标准来讲多的有61芯，但也可以根据用户要求生产了。
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. |
