25 kN Self-Gripping Conductor Clamp | Cable Grip for 150–240 mm² Transmission Line Conductors
1. Overview
The 25 kN Self-Gripping Conductor Clamp is a high-performance stringing tool designed for securely gripping and pulling 150–240 mm² conductors in overhead transmission line projects.
Its self-gripping design ensures safe, slip-free operation while reducing installation effort, making it ideal for ACSR, AAAC, and aluminum conductors.
This clamp is suitable for medium- and high-voltage transmission line construction, tower-to-tower stringing, and conductor tensioning.
2. Product Definition
A self-gripping conductor clamp is a mechanical device that automatically locks onto the conductor when tension is applied, providing a secure grip for pulling or tensioning.
This model is engineered for:
-
150–240 mm² ACSR, AAAC, or similar conductors
-
25 kN working load
-
Lightweight, durable aluminum or steel alloy construction
3. Key Features
• 25 kN Rated Load
Ensures secure conductor gripping for medium- to high-voltage line installations.
• Self-Gripping Mechanism
Automatically locks under load for safe and reliable conductor handling.
• Durable Alloy Construction
High-strength aluminum or steel alloy provides corrosion resistance and long service life.
• Smooth Grip Surface
Prevents conductor surface damage and reduces friction during pulling operations.
• Compact and Portable
Lightweight design allows easy transport and installation in the field.
4. Advantages
• Enhanced Safety
Self-gripping action eliminates accidental slippage during stringing operations.
• Quick Installation
No manual locking required; reduces labor and installation time.
• Wide Conductor Compatibility
Handles conductors in the 150–240 mm² range, suitable for ACSR, AAAC, and aluminum conductors.
• High Durability
Resistant to wear, corrosion, and repeated tensioning cycles.
• Compatible with Other Stringing Tools
Can be used with tensioners, pullers, rollers, and pilot ropes.
