The Difference Between Control Cable and Signal Cable

As we all know, cables can be subdivided into various products such as control cables and signal cables due to different requirements and occasions. There is a big difference between the two cables. So what is the difference between control cables and signal cables?

1. The characteristics of control cables and signal cables are different


Each core of the control cable is grounded with the rest of the core, the control cable is greater than 10000㏁.km, and the HYAT cable is greater than 3000㏁.km. Generally speaking, the signal transmitted by the signal line is very small. In order to avoid signal interference, there is a layer of shielding layer outside the signal line. The shielding layer of the wrapped conductor is generally conductive cloth, braided copper mesh or copper foil (aluminum), and the shielding layer needs to be grounded. This layer can introduce external interference signals into the ground, prevent interference signals from entering the inner conductor and reduce the loss of transmission signals.



2. The purposes of control cables and signal cables are different


Control cables are suitable for industrial and mining enterprises, energy and transportation departments, and PVC insulated and PVC sheathed control cables are used for control and protection circuits with AC rated voltage below 450/750 volts. Sensor signal cables are used for signal transmission of various sensors and instruments. The sensor signal line adopts silver-plated conductor and multi-core structure to ensure that the resistance between each core is highly consistent. It can accurately transmit weak electrical signals hundreds of meters away.



3. The materials of control cables and signal cables are different


The core of the control cable is copper core, the nominal cross-section is 2.5 mm or less, 2 cores to 61 cores; 4 to 6 mm, 2 to 14 cores; 10 mm, 2 to 10 cores. Working temperature of the control cable: 65°C for rubber insulation, 70°C and 105°C for PVC insulation. Control cables used in computer systems are generally insulated products made of polyvinyl chloride, polyethylene, cross-linked polyethylene, and fluoroplastics. The material of the signal line is a precise metal material. On the one hand, the interference signal must be smoothly exported. On the other hand, the extremely thin metal line must have sufficient bending resistance to prevent metal fragments from affecting other electrical equipment.



In fact, there is a big difference between the two cables. Signal lines are mostly used to transmit data signals, and the signal lines are shielded to prevent interference from external signals. Control cables are mainly used to transmit electrical signals. Normally there is no shielding. It is suitable for polyvinyl chloride insulation used in industrial and mining enterprises, energy and transportation departments, and control and protection lines of equipment with AC rated voltage below 450/750 volts.
