Description

If the tension on the cable exceeds its own weight and the weight of other loads, the cable will break and become unusable; underwater detection cables transmit both electrical energy and analog or digital signals, and interference will occur between the electrical energy and the signals, affecting the reliability of detection; water bodies are corrosive to a certain extent, which affects the service life of ordinary sheathed detection cables.
