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
