ความแตกต่างระหว่างสายควบคุมและสายไฟคืออะไร?
The differences between control cables and power cables are: 1. Different functions: power cables are used in the main line of the power system to transmit and distribute large-scale electrical energy; control cables are used for control wiring of electrical equipment and appliances. 2. Different categories: power cables belong to the second category of the five major categories of cables; control cables belong to the third category of the five major categories of cables (electrical equipment cables) 3. Different standards: the standard of power cables is GB12706; the standard of control cables It is 9330. 4. The identification of the insulated core wires is different: the insulation of the power cable is generally separated by color; the color of the insulated core of thecontrol cable is generally printed with a single-color digital serial number.
The color of the insulating core of the control cable is generally black and white, and the low voltage of the power cable is generally color-separated. The cross-section of the control cable is generally not more than 10 square meters, and the power cable is mainly used to transmit electricity, and generally has a large cross-section. The specifications of power cables can generally be larger, up to 500 square meters (the range that can be produced by conventional manufacturers), and there are relatively few manufacturers that can make large cross-sections, while the cross-section of control cables is generally small, and the maximum is generally not more than 10 square. In terms of the number of cable cores, the power cable is generally up to 5 cores according to the requirements of the
