Advantages Of High-strength Aluminum Alloy Bolt-type Tension Clamp In Overhead Lines

Publish Time: Author: Site Editor Visit: 6

A bolt-type tension clamp secures overhead conductors to tension towers, providing excellent mechanical grip and electrical connectivity. Manufactured from high-strength aluminum alloy, this dead end strain clamp prevents conductor slippage under extreme wind and ice loads while resisting atmospheric corrosion to ensure long-term grid stability.

Key Performance Benefits of Mechanical Fittings

Modern electrical grids demand robust hardware to maintain continuous power transmission. Utilizing a bolted type strain clamp significantly simplifies the installation process because linemen only require standard torque wrenches rather than specialized hydraulic compression tools, reducing field labor costs and installation errors substantially.

Mechanical Strength and Durability

High-strength aluminum alloy alternatives offer superior mechanical performance compared to traditional cast iron fittings. This specialized bolted dead end clamp distributes holding shielding forces uniformly across the conductor strands, preventing fatigue damage and extending the operational lifespan of critical power infrastructure lines.

  1. High tensile strength rating exceeding 95% of conductor UTS.

  2. Corrosion resistance in coastal and industrial environments.

  3. Removable design allows easy inspection and maintenance re-tensioning.

Technical Specifications and Core Data

Selecting appropriate hardware depends on precise physical dimensions and mechanical thresholds. The data below outlines typical parameters for high-strength aluminum alloy line hardware configurations used in medium to high voltage distribution networks worldwide.

Conductor Diameter (mm) Slip Strength (kN) Tightening Torque (N·m) Weight (kg)
9.0 - 14.0 45.0 44 1.4
14.1 - 22.0 70.0 44 2.3
22.1 - 32.0 110.0 85 4.1
