First of all, the number of the control cable often starts with the letter "C", which indicates that the control cable is specially designed to connect different sensors and control devices as a medium for signal transmission. This kind of cable can transmit data signals, and has a certain resistance to wear and chemical corrosion, so it is widely used in factory automation control systems.
Secondly, the control cable starting with the letter "A" mainly refers to the high-voltage control cable used between electrical equipment, which is used to connect high-voltage electrical equipment, transmit control signals, and establish protective isolation between various contact parts of electrical appliances. The structural characteristics of this cable are that the copper wire core not only has good conductivity, but also has good temperature resistance, self-fusing and humidity resistance, and has a wide range of use.
Again, the control cable starting with the letter "V" refers to a control cable with strong electromagnetic shielding and resistance to mechanical damage. It is mainly used for mechanical control of antistatic and radiation in various environments, and can be used for wiring systems, long-distance transmission equipment, connectors, etc. The surface covering sheath of this control cable is an insulating material, so that the cable has better tensile and drag resistance, fire resistance and aging resistance.
Finally, a control cable that starts with the letter "P" refers to a control cable with a layer of polyvinyl chloride (PVC) sheath on the surface of the cable. This kind of cable is characterized by high tensile strength, good resistance to mechanical damage, and has good fire resistance and acid and alkali resistance, and is often used in fireproof and moisture-proof environments of electrical equipment.
In short, the significance of the first letter of the control cable number is very important, it can better help users judge the performance and purpose of the cable, so as to save time and energy, and make the installation and use of electrical equipment more efficient and accurate.
