The Decisive Influence Of Torque Control On The Performance Of Bolt-type Tension Clamps

bolted type strain clamp plays an important role in fixing and tension transmission in power lines. The magnitude of the bolt torque directly affects the contact state between the clamp and the conductor. Even slight torque deviations can lead to uneven force distribution on the conductor, affecting overall tension stability. The performance of the dead end strain clamp is highly dependent on torque control during installation, which is especially important during construction and maintenance.

Factors Affecting Bolt Torque

The torque dependence of bolted dead end clamp involves multiple factors:

• Bolt specifications and material: Bolts of different materials exhibit different tightening effects under the same torque.

• Clamp contact surface condition: Oxidation or lubrication affects the relationship between bolt torque and actual tightening force.

• Installation environment conditions: Temperature and humidity significantly affect the maintenance of bolt preload.

These factors collectively determine the tension distribution and conductor fixation stability of bolt-type tension clamps during use.

Recommendations for Bolt Torque Management

During the construction and maintenance of bolt-type tension clamps, precise bolt torque management is essential. During operation, the corresponding torque value should be set according to the wire diameter and bolt specifications to ensure uniform stress on the clamp. Regularly checking the tightness of bolts can identify potential loosening risks, thereby maintaining a continuous balance of line tension.
