2×70 kN Hydraulic Cable Tensioner – Twin Conductor Stringing Equipment for Overhead Transmission Line

Model: GL2×70 (SA-ZY-2×70)

Product Overview

The GALAXY GL2×70 Hydraulic Cable Tensioner is specially designed for twin or single conductor stringing in high-voltage and extra-high-voltage overhead transmission line construction up to 500 kV.

With a dual-drum hydraulic circuit and electronic closed-loop control, it provides smooth, stepless tension adjustment and precise conductor protection under all working conditions.
It is ideal for long-distance, large-span, and complex-terrain stringing operations.
