Tension clamps (also known as strain clamps or dead-end clamps) are fittings used to secure conductors, bearing the tension of the wires while connecting them to strain assemblies or poles.

Classification

Tension clamps can be broadly categorized into two types based on their structure and installation conditions:

Type One: These clamps bear the entire tensile force of the conductor or lightning wire, with a gripping force not less than 90% of the rated tensile strength of the installed wire. However, they do not serve as conductive bodies. This type of clamp can be removed and reused after the conductor is installed. Examples include bolt-type tension clamps and wedge-type tension clamps.

Type Two: In addition to bearing the full tensile force of the conductor or lightning wire, these clamps also function as conductive bodies. Once installed, they cannot be removed, earning them the name "dead-end clamps." Because they are conductive, their installation must strictly adhere to relevant operational procedures.

Applications

Tension clamps are used for corner, joint, and terminal connections.

Features:

Spiral Aluminum-Clad Steel Wire: This wire offers exceptional tensile strength and minimizes concentrated stress, providing protection and vibration damping for the fiber optic cable.

Complete Set of Fittings: The complete assembly includes tension pre-stranded wires and corresponding connection fittings.

Installation Efficiency: The gripping force is not less than 95% of the rated tensile strength of the fiber optic cable, allowing for convenient and quick installation, thereby reducing construction costs. This type of clamp is suitable for spans ≤ 100 meters and angles < 25° in ADSS fiber optic lines.
