Control cables have the characteristics of moisture resistance, corrosion resistance, and damage prevention, and can be laid in tunnels or cable trenches. Power cables are used in the backbone of the power system to transmit and distribute high-power electrical energy. Control cables directly transmit electrical energy from the distribution points of the power system to the power connection lines of various electrical equipment and appliances. The rated voltage of power cables is generally 0.6/1kV and above, while control cables are mainly 450/750V. When producing power cables and control cables of the same specifications, the insulation and sheath thickness of power cables is thicker than that of control cables.
(1) Control cables belong to electrical equipment cables, and power cables are two of the five major categories of cables.
(2) The standard for control cables is 9330, and the standard for power cables is GB12706.
(3) The color of the insulation core of control cables is generally black with white lettering, and low-voltage power cables are generally color coded.
(4) The cross-sectional area of control cables generally does not exceed 10 square meters, while power cables are mainly used for transmitting electricity and are generally large in cross-section.
Due to the reasons mentioned above, the specifications of power cables can generally be larger, up to 500 square meters (the range that conventional manufacturers can produce), and there are relatively few manufacturers that can produce even larger cross-sections. On the other hand, the cross-section of control cables is generally smaller, with a maximum of no more than 10 square meters.
In terms of the number of cable cores, power cables generally have a maximum of 5 cores according to the requirements of the power grid, while control cables used for transmitting control signals have a larger number of cores, with 61 cores according to standards, but can also be produced according to user requirements.
