Bolt-type Tension Clamp Anti-reverse Mechanism: The Meshing Principle Of The Fastening Teeth

The conductor fixing in the tension section of the transmission line relies on the locking force provided by bolted type strain clamp. The anti-reverse mechanism inside dead end strain clamp, through the synergistic action of the fastening teeth and the anti-reverse teeth, prevents the conductor from shifting back during tension fluctuations.

The fastening teeth are distributed inside the groove of bolted dead end clamp, arranged in a serrated pattern with the tooth tips pointing in the direction the conductor enters. When the bolt is tightened, the fastening teeth press into the conductor surface to form an embedded engagement. The tooth angle is typically designed to be 30-45 degrees; this angle range can generate a wedging effect when the conductor is under tension. The greater the force on the conductor, the stronger the radial pressure of the fastening teeth, and the greater the engagement depth. The tooth pitch design needs to match the conductor strand pitch, so that multiple tooth tips act simultaneously on different strand units, dispersing concentrated stress.
