Bolt-type Tension Clamps Are Not Suitable For Applications Requiring Tension Release.

The mechanical connection of bolted type strain clamp relies on the initial preload of the threaded fasteners. During repeated disassembly and reassembly, the fastener threads may experience wear, preload reduction, or uneven contact surface changes, affecting the overall mechanical condition of the connection. When the conductor is inspected or partially adjusted on site, these mechanical changes of dead end strain clamp can introduce instability into the tension release process.

During the installation and maintenance of overhead conductors, tension often needs to be gradually released or redistributed through specific mechanisms. bolted dead end clamp was not designed for tension adjustment operations; its connection method, under repeated stress cycles, may exacerbate fatigue in the threaded portion or cause changes in the contact surface, thereby altering the stress state of the conductor.
