Construction Plan & Execution

1. Route Planning & Site Selection

The transmission line traverses mountainous terrains, river valleys, and densely populated areas, requiring:
• Topographical and geological assessments to determine optimal tower locations.
• Seismic and weather resilience studies for long-term structural integrity.
• Environmental impact evaluations to minimize ecological disruption.

Using GIS (Geographic Information System) modeling, the route was optimized to reduce land use conflicts and ensure maximum transmission efficiency.
2. Tower Construction & Foundation Engineering

The 345 transmission towers were engineered to withstand harsh weather conditions and seismic activities. The construction process included:
• High-strength steel lattice towers for maximum durability.
• Galvanized anti-corrosion coatings to prevent environmental degradation.
• Optimized tower designs to minimize land footprint and visual impact.

Foundation types varied based on geological conditions:
• Rock-anchor foundations for mountainous areas.
• Deep-pile foundations in soft soil regions.
• Bored pile foundations for high-load-bearing capacity.

In steep and inaccessible locations, helicopter-assisted tower installation was utilized to enhance efficiency and reduce environmental impact.
3. Conductor Installation & Stringing

The transmission line employs high-performance conductors and insulators, ensuring:
• Reduced energy loss with ultra-low resistance conductors.
• Improved weather resilience with anti-icing and anti-corrosion coatings.
• Enhanced grid safety using composite polymer insulators.

Tension stringing techniques were used to maintain precise conductor alignment, optimizing electrical performance and reducing transmission losses.
