The following are related information Power cables are used to transmit and distribute large-functional electrical energy in the power system backbone, and the control cables transmit the power directly from the distribution point of the power system to the power connection lines of various electrical equipment and appliances.
The rated voltage of the power cable is generally 0.6/1kV and above, and the control cable is mainly 450/750V. When power cables and control cables of the same specifications are manufactured, the insulation and sheath thickness of power cables is thicker than that of control cables.
First of all, the control cable belongs to the cable for electrical equipment, and the power cable is two of the five categories of cable. The standard of the control cable is 9330. The standard of the power cable is that the color of the insulated wire core of the GB12706 control cable is generally black and white, and the low voltage of the power cable is generally a color separation.
The cross section of the control cable generally does not exceed 10 square meters. The power cable is mainly used for power transmission and generally has a large section. Due to the reasons mentioned above, the specifications of power cables can generally be larger, as large as 500 square meters (range that conventional manufacturers can produce), and relatively few manufacturers can do as large cross-sections as possible, and the cross-section of control cables is generally small. Smaller, the maximum is generally not more than 10 square. From the perspective of the number of cable cores, the power cable is generally up to 5 cores according to the grid requirements, while the control cable transmits control signals with a higher number of cores. According to the standard, there are more than 61 cores, but it can also be produced according to user requirements. .
What is the difference between power cable and control cable?
The use of power cables and control cables is not the same. Power cables are 0.6/1kv such as VV, YJV. The control cable is 450/750v, such as KVV, KVVP general power cables are all within 5 cores. Generally, it is used for strong control of cable cores. Sometimes customers have different requirements, generally to 37 cores, but there are also more cores.
