[0002] Due to the country's policy adjustments on mechatronics, equipment automation, and equipment intelligence in recent years, the competition for upgrading the intelligent equipment industry has become increasingly fierce. The implementation of the policy has also accelerated the breakthrough of traditional design ideas in the manufacturing and processing of cable industry products, and gradually made great adjustments and additions to new materials, new structures, and new processes in new products. Since cables are key control parts for maintaining electrical equipment / equipment, their excellent performance largely determines the quality of the equipment.

[0003] Based on the above situation, automatic robots and intelligent equipment terminal devices, especially electrical control equipment connection lines, are one of the key components for connecting electrical circuits. They mainly play the role of electrical connection and signal transmission between devices and components, components and cabinets, root control systems and subsystems. The quality of their signal transmission is related to the reliability and stability of the overall operation of the system equipment, and is particularly important.

[0004] For conventional electrical connecting wires, bare copper conductors are commonly used. They are easily oxidized in high temperature environments, and the resistance gradually increases, which will cause the conductor to heat up more and more seriously, resulting in power loss or signal weakening and distortion leading to misoperation; the insulation of conventional connecting wires is generally made of polyvinyl chloride, polyethylene, cross-linked polyethylene, polyolefins and other materials. The materials are hard and not environmentally friendly, and their laying and environmental use do not meet customer requirements.
