Flexible cables are mainly used in industrial production automation technology, automatic production line system software, intelligent robots, and other places that must move back and forth. In order to better avoid winding, damage, breaking, hanging and scattering of the cable, the cable is often put into the chain.

According to the introduction of wire and cable manufacturers, flexible cable is the preferred choice of cable for power transmission and signal transmission carrier in the cable movement system of drag chain, which is also called drag chain cable, mobile cable and robot cable. Cable's conductor structure is mainly based on the stranded copper conductor structure of the IEC 228 standard of the cable. The sheath is mostly made of low viscosity and flexible wear-resistant materials to slow down the wear rate of the cable in continuous round-trip movement.

According to the function, flexible cables can be divided into sensors, encoders, servo cables, robot cables, cleaning cables, etc. Due to many characteristics, the flexibility in use has reached a higher standard, and cannot be effectively changed due to environmental factors. Servo towing cable with shielding performance, oil resistance, acid and alkali resistance, hydrolysis resistance. The characteristics of anti-ultraviolet and low temperature resistance will make the use of the cable more convenient because of the above characteristics. Because of these characteristics, the service life of the cable will be longer, and the use method will be different due to more different use rights, thereby extending the life.

Flexible cables are usually made into drag chain motion systems. As an excellent power transmission material, it is widely used in all walks of life. Because of its good flexibility, more applications are being found. For example, today's flexible cables are used not only for power transmission, but also for signal transmission.

Wire and cable manufacturers said that the general flexible cable has the advantages of bending characteristics, flexibility, wear resistance, acid and alkali resistance, and compressive strength. Generally used for mobile equipment in automation technology, such as production line workshops of automation technology companies, robotic arms of DC welding machines, testing instruments, etc.

In order to protect the flexible cable from wear during movement and maintain good flexibility, the sheath is generally made of flexible wear-resistant material. This material has low viscosity, but high hardness, good flexibility, toughness and wear resistance, and can well withstand the wear caused by movement. However, it should be noted that we still need to reduce the resistance of flexible cables in daily use to reduce wear and extend life.

Wire and cable manufacturers pointed out that the outer jacket of flexible control cables mainly uses three materials: PVC,PUR,PETP, which are common in PVC materials. These three materials are high-density materials, which can effectively prevent cable wear. This cable is characterized by flame retardant, small bending radius, PUR and PETE materials have better resistance, can be acid and alkali resistance, temperature resistance and UV resistance.
