The Conductor Is Not Allowed To Slide Axially Within The Bolt-type Tension Clamp.

To maintain stable contact between the wire and bolted type strain clamp, the clamp construction and fastening process must match the material properties and diameter specifications of the wire. Once the conductor is placed in the clamping slot of dead end strain clamp, the bolt applies pressure with a predetermined torque value, so that the clamp and the conductor have sufficient static friction torque to resist possible axial movement. In bolted dead end clamp, the arrangement of bolts, material hardness, and friction surface shape all play a role in preventing the wire from sliding axially within the fitting.

Considering the effects of mechanical loads and vibrations, checking the integrity of the clamping surface and the bolt fit accuracy during installation is crucial. In terms of design, a reasonable allocation of the clamping area length and contact surface geometry restricts minor longitudinal movement of the conductor along the clamp while ensuring the stress stability of the contact point during line operation.
