Hybrid cables, as core components of modern power transmission and signal communication systems, directly impact the safe and stable operation of the entire system through their performance and reliability. In power systems, rail transportation, industrial automation, and new energy fields, hybrid cables perform multiple functions, including power transmission, data exchange, and control signal transmission. The complexity of their internal structure and the diversity of their operating environments place extremely high demands on cable quality. Because hybrid cables typically contain multiple transmission media such as power lines, control lines, signal lines, and optical fibers, any insulation damage, shielding failure, or poor conductor contact can lead to system failures, data loss, or even safety accidents.
Therefore, systematic hybrid cable testing is not only a necessary verification of product quality before shipment but also a key technical means to prevent system failures and ensure operational safety. With the development of smart grids and Industry 4.0 technologies, the application scenarios of hybrid cables are expanding, and the importance of their testing technology is becoming increasingly prominent.
