Why Are Bolt-type Tension Clamps Not Suitable For Use In Environments Requiring Repeated Disassembly And Assembly?

Connection points often require repeated disassembly and assembly, such as during conductor inspection, adjustment, or replacement. For bolted type strain clamp, each disassembly and assembly process involves repeated twisting and tightening of bolts, and the mechanical characteristics of bolt connections themselves are prone to wear, thread deformation or preload decay after frequent use. For dead end strain clamp bolted connections, the maintenance of preload and thread integrity are crucial; excessive operation may lead to unstable torque or loosening of the connection.

In high-voltage or overhead line environments, the installation angle and conductor stress conditions of bolted dead end clamp are complex. Installation errors or repeated disassembly and assembly may cause uneven contact between the clamping surface and the conductor, altering the overall mechanical condition of the connection point.
