The Sliding Engagement Mechanism Between The Bolt-type Tension Clamp Block And The Compression Sleeve

In the installation and maintenance of power lines, the sliding fit design between the clamp block and the compression sleeve provides flexibility for construction. This fit allows operators to adjust the clamping position according to the actual condition of the conductor, meeting installation requirements under different working conditions.

Structural principle of sliding fit

The bolted type strain clamp wire clamp block adopts a split design. The extrusion sleeve forms a fit relationship with the outer surface of the wire clamp block through a specific tapered or stepped inner cavity. When the bolts at dead end strain clamp are not fully tightened, the clamp block can generate axial displacement inside the extrusion sleeve. This bolted dead end clamp design allows the wire to naturally find the force balance point during clamping, reducing stress concentration problems caused by preset position deviations.
