Bolt-type Tension Clamps Are Always Acting Up? Don't Overlook These Common Types Of Faults During Routine Inspections

Power lines inevitably encounter problems over time, with the metal components hanging on poles being the most prone to failure. Inspectors frequently find sagging lines or sparking, and upon closer inspection, these are mostly due to hardware wear and tear. Today we'll talk about the parts of bolted type strain clamp that everyone is most concerned about and that are prone to failure, so that you won't lose your way when you're working.

Several Typical Signs of Failure

The problems here are varied, but generally fall into two categories: electrical contact and physical structure.

• Overheating and Burning of Contact Surfaces

If nuts are not tightened sufficiently, over time, high resistance will develop at the contact surface. Heat will accumulate when current flows through. An oxide layer will form on the aluminum alloy surface, directly reducing conductivity. In severe cases, the entire dead end strain clamp clamp can burn and discolor.

• Loosening and Slipping of Bolts

Years of exposure to wind and rain, combined with line vibration, can easily cause screws to loosen. This physical damage is difficult to detect in the early stages. Once the clamping force decreases, the conductor experiences uneven stress, and the entire section of wire is at risk of slipping.

• Metal Corrosion

Prolonged exposure to the elements allows rainwater to seep into crevices. Rusting is particularly noticeable in coastal or industrial areas. Rust can make even sturdy metal components brittle.

Construction Details Determine Lifespan

Incorrect installation technique can lead to numerous problems later. Insufficient torque can double maintenance costs. Monitoring the assembly quality of bolt-type tension clamps is crucial for the entire line's lifeline.

Operators must pay attention to the position of washers. Misaligned washers can cause force misalignment. The tightening sequence of bolts is also important. Uneven force can cause the clamps to deviate.

Hazard Identification Tips

Sun and rain exposure can cause metal surfaces to peel. During regular inspections, check for reddish-brown rust at connections. Replace any problematic parts promptly to avoid major accidents. Regularly measuring joint temperature is also a good practice. Excessive temperature indicates a problem.

Maintaining stable bolted dead end clamp operating conditions requires long-term, meticulous observation. Record any abnormalities immediately. Replace damaged parts quickly.
