Overhead conductors are subject to various stresses over their lifetime, including mechanical tension, thermal cycling from electrical loads, and environmental factors like corrosion and wind. These factors can lead to material fatigue, strand breaks, and ultimately, conductor failure.

Our professional answer:

Understanding the factors that contribute to conductor aging is crucial for proactive maintenance. At Ningbo Changshi, we provide equipment and solutions that help utility providers manage and mitigate these risks. Key factors include:

• Creep and Annealing: Permanent elongation of aluminum strands over time (creep) and softening from prolonged high temperatures (annealing) both reduce the conductor's mechanical strength.

• Corrosion and Fatigue: Environmental factors like pollution, salt-laden air, and wind-induced vibrations can cause corrosion and fatigue, leading to strand failure.

Our conductor maintenance tools and accessories, such as Hydraulic Compressors and wire grips, are designed for the repair and splicing of conductors, helping to restore mechanical integrity. We also supply vibration dampers and stockbridge dampers to protect conductors from wind-induced fatigue, extending their operational life and improving grid reliability.
