Plastic Response Characteristics Of Bolt-type Tension Clamps

In the load-bearing system of overhead power lines, the microscopic response of the structure under load directly affects the clamping stability. bolted type strain clamp exhibits controlled deformation characteristics under tension, the core of which lies in the coordinated force between the clamp and the fastening system.

Structural stress and plastic release mechanism

dead end strain clamp Relying on the clamping force applied by the U-bolt, a frictional locking relationship is formed between the wire groove and the wire. When the external tension increases to a certain range, limited plastic deformation will occur in local areas. This deformation is not a signal of structural weakening, but rather a manifestation of stress redistribution. This type of clamp relies on bolt pressure and wire groove friction to fix the conductor and possesses the basic structural conditions to bear tension.

Stable State under Deformation Control

bolted dead end clamp Design Manifestations

• Local Compression Zone Adjustment: The clamping material undergoes slight plastic flow in high-stress areas, reducing stress concentration.

• Bolt Preload Compensation: Fasteners maintain continuous compression, ensuring clamping capacity even after deformation.

• Friction Interface Stability: The corrugated groove structure maintains effective contact area during deformation.

This controlled plastic behavior allows the bolt-type tension clamp to maintain structural integrity under complex load environments, rather than entering a failure mode.

From an engineering perspective, the plastic response of the bolt-type tension clamp is not a defect, but a predictable mechanical buffering path, forming a unified system with its clamping mechanism.
