Mountain Transmission Project in Peru – Improving Stringing Efficiency by 35%

Project Background

A transmission contractor in Peru was assigned a 220kV power line project across mountainous terrain. The project faced severe challenges including steep slopes, unstable ground conditions, and limited equipment mobility. Traditional tensioning equipment could not maintain stable conductor tension, resulting in inefficiency and safety risks.

Customer Pain Points

• Difficulty maintaining consistent tension in mountainous terrain
• Frequent conductor slippage due to uneven load
• Low efficiency in twin-bundle conductor stringing
• High labor and time costs

Our Solution

We provided the 2x40KN Hydraulic Wheel Tensioner (TY2x40-1800), specifically designed for demanding terrains.

Key configurations applied:

• 1800mm large bull-wheel diameter for better grip and reduced conductor wear
• 2×40kN continuous tension ensuring stable operation
• Cummins diesel engine (77kW) for reliable power output
• German Rexroth hydraulic system for precise control

Implementation Process

The equipment was deployed across multiple tower sections in mountainous areas. The hydraulic tension preset system allowed operators to maintain consistent tension without manual adjustments, significantly improving safety and efficiency.

Results Achieved

• 35% increase in stringing efficiency
• 40% reduction in labor intensity
• Zero conductor damage during installation
• Improved project delivery timeline

Customer Feedback

“The machine maintained excellent tension control even on steep slopes. It significantly improved our productivity and reduced operational risks.”

Summary

This case demonstrates that the hydraulic wheel tensioner for transmission line stringing is highly suitable for mountainous projects, especially for twin-bundle conductors up to 630mm².
