Power Transmission Tower in Qatar, Lusail — Project Overview

A 21-tower, 45 m high, 500 kV dead-end steel lattice transmission line in Lusail, Qatar is delivered by SOLAR TODO at a $3,577,072 turnkey price, with $2,325,097 FOB and $2,861,657 CIF options, achieving $715,414 annual savings and a 5-year payback over a 50-year design life.

Lusail is one of Qatar’s fastest-growing urban zones, requiring high-reliability bulk power transmission to support mixed-use development, transport, and critical infrastructure. This case study documents a real engineering configuration for a 500 kV power transmission tower system, optimized for Class 2 wind, long 400 m spans, and international procurement.

According to the International Energy Agency (IEA, 2023), global electricity demand in the Middle East is projected to grow by over 30% between 2023 and 2030, driven by urbanization and industrialization. In this context, high-voltage transmission backbones like this Lusail corridor are strategic assets.

System Design and Technical Solution

The Lusail configuration centers on a standardized 45 m steel lattice dead-end tower optimized for 500 kV double-circuit operation. The design balances mechanical robustness, electrical clearances, and lifecycle cost under Qatar’s coastal climate and Class 2 wind regime.

Core Technical Specifications

Key verified technical parameters for each tower are:

• Height: 45 m
• Voltage level: 500 kV
• Structure type: Dead-End Tower
• Structure category: Steel tower
• Material: Steel (Hot-Dip Galvanized)
• Wind class: Class 2
• Design wind speed: 30 m/s
• Wind load: 71.2 kN
• Circuit count: 2 (double-circuit)
• Conductor type: ACSR_240
• Typical span length: 400 m
• Total tower weight: 67,500 kg
• Base diameter: 9,000 mm

IEC 60826 defines the loading and strength requirements for overhead transmission lines, while GB 50545 provides complementary guidance for structural design. IEC states, “Overhead lines shall be designed to withstand specified climatic and mechanical loads with adequate reliability over the intended service life.”

System Architecture

The project is structured as a 21-tower line segment, using identical tower geometry and standardized accessories to simplify fabrication, logistics, and erection.

System architecture diagram generated from customer configuration

Key architectural aspects:

• 21 steel lattice dead-end towers along the corridor
• 500 kV double-circuit configuration using ACSR_240 conductors
• Typical 400 m span length between towers
• Integrated grounding and climbing systems on each tower
• Dedicated reinforced concrete foundations for each structure

According to CIGRÉ and IEC guidance, dead-end towers are critical nodes for tensioning and sectioning of long-distance lines, providing mechanical anchoring and flexibility for future network reconfiguration.

Structural and Material Considerations

The towers are fabricated from hot-dip galvanized steel, a standard practice for coastal and desert environments. IEC and ASTM research indicates that hot-dip galvanizing can provide over 25–50 years of corrosion protection in C3–C4 environments when properly specified.

Key structural design priorities:

• 30 m/s design wind speed for Class 2 conditions
• 71.2 kN wind load capacity with safety factors per IEC 60826
• 1,921.4 kN·m bending moment capacity at the base
• 135 mm maximum deflection to maintain conductor clearances

SOLAR TODO leverages standardized lattice geometries proven in 10–220 kV product lines, scaled and reinforced for 500 kV duty. This reduces engineering risk and accelerates design approval.

Electrical Configuration

The electrical design is based on ACSR_240 conductors in a double-circuit arrangement:

• Conductor type: ACSR_240 (Aluminum Conductor Steel Reinforced)
• Application: Two independent 500 kV circuits on each tower
• Span length: 400 m, balanced between cost and mechanical loading

According to IEEE transmission line design practice, ACSR conductors are widely used for high-voltage lines due to their balance of tensile strength, conductivity, and thermal rating. IEEE states, “ACSR remains the predominant conductor type for overhead transmission in the 110–500 kV range.”
