What Is The Difference Between A Wedge-type Tension Clamp Rod And A Tension Plate?
The main difference between pulling rods and pulling straps in a wedge-type tension clamp lies in their mechanical structure and load handling. Pulling rods are rigid, cylindrical steel bars designed for linear, heavy-duty axial tension. Pulling straps are flat, flexible metal plates that offer versatile multi-angle adjustment for compact overhead distributions.
Mechanical Roles in Overhead Line Insulation
Overhead power distributions rely heavily on a robust clamp dead end mechanism to secure aerial bundled cables. The primary fungsi dead end clamp configuration is to anchor conductors firmly under extreme weather conditions. Choosing between specific hardware components ensures long-term operational safety and prevents structural sagging across overhead line spans.
Detailed Comparison of Internal Components
While a dead end clamp for abc cable installations utilizes both components, their physical capabilities differ significantly during field operations. The following technical specifications outline how these parts perform under standard mechanical stress tests:
| Technical Parameter | Pulling Rod Component | Pulling Strap Component |
|---|---|---|
| Geometric Shape | Solid cylindrical bar | Flat rectangular plate |
| Load Capacity | High axial tension (up to 70 kN) | Medium tension (up to 45 kN) |
| Installation Flexibility | Fixed linear alignment | Multi-angle adjustable positioning |
Structural Analysis of Pulling Rods
Pulling rods provide direct, rigid linear connections within heavy-duty power lines. These components feature threaded ends that allow precise tension adjustments during high-voltage system setups. The solid steel design eliminates bending risks, making them ideal for long-span high-load overhead distributions worldwide.
Functional Benefits of Pulling Straps
Pulling straps provide excellent directional flexibility in confined spaces. A standard dead end clamp for ab cable networks utilizes flat straps to wrap around pole brackets easily. This flat configuration distributes bending stress evenly across the attachment point, reducing fatigue during continuous wind vibrations.
Selecting the Right Dead End Component
Proper hardware selection depends on specific installation parameters and physical limitations:
-
Opt for rigid pulling rods when cross-span distances exceed 120 meters.
-
Select flexible pulling straps for complex urban pole connections.
-
Match component load limits with the overall cable tension ratings.
