Bolt-type Tension Clamp Axial Positioning Technology

Maintaining stress balance at the metal-to-metal contact interface at tension nodes of high-voltage transmission lines is crucial for long-term reliability. The bolted type strain clamp fastener displacement control is directly related to the long-term stability of the wire gripping force. The engineering team's core focus is on establishing a rigid constraint mechanism for geometric position.

The uniformity of pressure distribution in dead end strain clamp depends on the precision of the structural design. The anti-deviation requirements for heavy-duty clamps used in ultra-high voltage lines are much higher than those in medium and low voltage scenarios. The groove guidance accuracy (tolerance ±0.1mm) of the bolted dead end clamp body, the anti-slip texture depth (usually ≥0.3mm) of the fastening plate side edge, and the rigidity index of the torque transmission mechanism together constitute the basis of the anti-displacement technology. Installers need to match the corresponding structural version according to the wire type (e.g., JL/G1A-630/45).
