What are the common causes of overhead line clamp failure and how can it be prevented?

2025-08-13

overhead line clamp failure can be caused by a few key factors:

  1. Loose Connections: Over time, vibrations caused by wind can loosen bolts, increasing contact resistance and causing abnormal heating, which accelerates oxidation and corrosion.

  2. Improper Installation: Failure to use the correct clamp for the conductor type or not applying the recommended torque can lead to insufficient grip and premature failure.

  3. Environmental Stress: Extreme weather, such as heavy ice loads or strong winds, can exert forces beyond the clamp's rated capacity, leading to damage. Prevention is key: always choose the correct clamp for the application, ensure proper installation using recommended torque values, and perform regular inspections and maintenance to check for loose bolts, corrosion, or signs of overheating. Our products are designed with materials and structures that mitigate these risks, ensuring long-term operational safety.
