CY cable SY cable YY cable
Control cables encompass a large family of cables for measurement and modulation applications, manufactured to various British, European and international Standards.These include the widely used CY cable, SY cable, YY cable, and LiYCY & LiYY cables designed for a wide range of industrial process automation applications, including signal transmission, measurement, control and regulation. These control cables are often referred to by the application, such as machinery supply cable, motor cable and robotics cable. They are also known as multi-core cables, control flex and control flexible cables.

Shielded control cable-（CY cable SY cable YY cable）
Features
Features
Shielding effect：
Shielding electromagnetic interference: The current passing through the power cable is relatively large, and a magnetic field will be generated around the current. In order not to affect the normal operation of other components, the shielding layer can wrap the signal or power wire inside, which can prevent electromagnetic noise interference in two ways.
Grounding protection: To prevent the cable core from being damaged and the current from leaking out, the cable with a shielding layer can allow the leaked current to flow into the grounding grid, effectively guide the interference current into the earth, and play a role in safety protection.
The ability to resist external electromagnetic interference and the ability of the system itself to radiate electromagnetic interference outward, effectively filtering out unnecessary electromagnetic waves.

Electrical Interference Problem
Due to the electromagnetic induction interference generated by the power-on current, KVVP cables may be affected by electrical interference after laying. This interference may come from nearby high-voltage and high-current interference sources, or interference between different cores in the same cable. Electrical interference may cause unstable signal transmission and even cause malfunction. To solve this problem, the following measures can be taken:
Ground a spare core in the control cable to reduce the amplitude of the interference voltage.
For circuits where electrical interference will have serious consequences, it is necessary to avoid sharing a control cable, especially weak-current signal control loops and strong-current signal control loops, low-level signals and high-level signal loops, etc.
The use of metal shielding is an important measure to reduce and prevent electrical interference, including total shielding, sub-shielding and double-layer total shielding of the core.
Manufacturing Defects and Quality Problems
KVVP cables may have some defects during the manufacturing process, such as insulation eccentricity, uneven insulation shielding thickness, impurities in the insulation, and cable moisture. These defects may cause the cable to fail during use, affecting the stability and safety of signal transmission. Therefore, when purchasing KVVP cables, you should choose manufacturers with reliable quality and good reputation, and strictly conduct quality inspections.
Construction and Installation Issues
During the construction and installation process, KVVP cables may be affected by mechanical damage, insulation damage and other problems. For example, the cable may be scratched or squeezed during the laying process, resulting in damage to the insulation layer; the cable joints may have air gaps and impurities due to poor workmanship or material problems during the production process, affecting the insulation performance of the joints. In order to solve these problems, the laying of cables and the production of joints should be carried out in strict accordance with the construction specifications and process requirements to ensure the quality of cables and joints.
Long-Term Operation and Maintenance Issues
KVVP cables may be affected by a variety of factors during long-term operation, such as excessive load, high temperature, humid environment, etc. These factors may cause cable insulation aging and performance degradation. In addition, cable maintenance and management are also important links to ensure the safe operation of cables. Improper maintenance or poor management may cause cable failures or accidents. Therefore, cables should be inspected and maintained regularly to detect and deal with potential problems in a timely manner.
