What is the difference between power cable shielding layer and control cable

China [CN]

The difference between the power cable shielding layer and the control cable lies in the function, category, standard, and the identification of the insulated core. The following is a detailed description of these categories.

Function: Power cables are used in the main line of the power system to transmit and distribute large-function electric energy; control cables are used for control wiring of electrical equipment and appliances.  

Category: power cables belong to the second category of the five cable categories; control cables belong to the third category of the five cable categories (cables for electrical equipment).  

Standard: The standard for power cables is GB12706; the standard for control cables is 9330.

Identification of insulated core wires: the insulation of power cables is generally separated by color; the color of the insulated cores of control cables is generally printed with a single-color digital serial number.  

The above is the whole content of the difference between power cables and control cables. Power cables are cables used to transmit and distribute electric energy. Power cables are often used in urban underground power grids, power station lead lines, internal power supply of industrial and mining enterprises, and underwater transmission lines across rivers and seas. . In power lines, the proportion of cables is gradually increasing.
