GL2X40 KN Overhead Line Stringing High-Voltage Twin Conductor
Tensioning Pulling Machine
How to Choose the Right Twin-Conductor Hydraulic Tensioner for
Medium and High Voltage Lines?
The GL-2×40 hydraulic tensioner from GALAXY is designed for
double-conductor stringing operations, offering high precision and
stability in medium- and high-voltage transmission line projects.
Equipped with a powerful Cummins diesel engine and German Rexroth
hydraulic systems, it delivers reliable performance across diverse
terrains, including mountainous regions and urban networks.
Application:
Ideal for tension stringing of twin-bundle conductors up to 630mm²
in mountainous areas, and up to 720mm² in flat terrains. Also
compatible with OPGW, ADSS optical cables, and 500kV haulage rope
deployment.
Key Advantages:
• Twin-drum synchronized tensioning
• Strong pull force: up to 2 × 45kN intermittent
• Premium components: Cummins, Rexroth, Eton, WIKA
• Suitable for multiple conductor types & cable sizes
• Optimized for both flatlands and complex terrain

Working Principle
The diesel engine drives a twin hydraulic drum system to maintain
balanced tension on both conductors, with real-time adjustment via
Rexroth hydraulic valves. The unit ensures sag-free, synchronized
deployment with minimal conductor stress.
FAQ:
