These clamps are engineered to maintain their performance across varying terrains, making them indispensable for overhead cable installations in challenging environments.
How ADSS Tension Clamps Work
Mechanism of Securing Cables with Self-Adjusting Wedges
ADSS Tension Clamps utilize a straightforward yet effective mechanism to secure cables. The self-adjusting wedges inside the clamp automatically grip the cable when tension is applied. This process ensures a firm hold without damaging the cable's outer layer. The installation involves several precise steps:
- Tighten the cable using a cable pulley or pulling sock.
- Apply the rated mechanical tension value using a ratchet tensioning puller.
- Attach the clamp's wire bail to a preinstalled hook or pole bracket.
- Position the clamp over the cable and insert the cable into the wedges.
- Gradually release the tension, allowing the wedges to secure the cable.
- Remove the tensioning puller and repeat the process for the other side of the cable.
- Deploy the cable along the line using a pulley to prevent bending.
This method ensures a secure and reliable installation, minimizing the risk of slippage or misalignment during operation.
Note: Proper installation of ADSS Tension Clamps enhances the durability and performance of overhead cable systems.
Prevention of Cable Strain and Damage
ADSS Tension Clamps play a critical role in protecting cables from strain and damage. By evenly distributing mechanical stress across the cable, these clamps prevent localized pressure points that could lead to wear or breakage. The self-adjusting wedges adapt to the cable's diameter, ensuring a snug fit without exerting excessive force. This design reduces the risk of deformation or cracking, even under high tension.
The clamps also maintain consistent tension throughout the cable's length, which is essential for preventing sagging or misalignment. This feature is particularly important in environments with strong winds or heavy snow, where cables are subjected to additional stress. By safeguarding the cable's structural integrity, ADSS Tension Clamps contribute to the longevity and reliability of the entire installation.
Role in Supporting Line Load and Maintaining Alignment
ADSS Tension Clamps are engineered to support the line load effectively while maintaining proper alignment. They stabilize cables in overhead installations, ensuring that the load is evenly distributed across the span. This prevents sagging and maintains the required clearance between the cable and surrounding structures.
- In transmission lines, these clamps provide essential support for conductors, ensuring proper tension and alignment.
- For communication lines, such as fiber optic cables, they enable uninterrupted signal transmission by minimizing movement and strain.
- In railway electrification systems, the clamps maintain the alignment of overhead contact wires, ensuring consistent performance.
The robust construction of ADSS Tension Clamps allows them to withstand environmental challenges, such as strong winds and temperature fluctuations. Their ability to maintain alignment and support the line load makes them indispensable for overhead cable systems in various industries.
Types of ADSS Tension Clamps
Short Span ADSS Tension Clamps

Choosing the Right ADSS Tension Clamp
Evaluating Cable Specifications and Load Requirements
Selecting the appropriate ADSS Tension Clamp begins with understanding the cable's specifications and load requirements. Factors such as cable diameter, tensile strength, and span length play a critical role in determining the clamp's suitability. For short spans, lightweight clamps with lower tensile ratings are ideal. Medium and long spans demand reinforced clamps capable of handling higher loads. Engineers must also assess the cable's mechanical stress tolerance to ensure long-term reliability.
Considering Installation Conditions and Environmental Factors
Installation conditions and environmental factors significantly influence the choice of ADSS Tension Clamps. Engineers evaluate pole loading and wind load calculations to ensure mechanical stability under varying conditions. Tension and sag analysis helps optimize cable tension and minimize stress. Environmental stress testing simulates real-world conditions to verify the clamp's structural resilience.
