Background
In 2024, the Togo Electric Power Company launched a grid modernization program aimed at improving the reliability and safety of its medium- and low-voltage distribution networks. The project involved upgrading aging infrastructure, reducing power outage frequency, and improving protection against lightning and overvoltage events—critical issues in Togo’s tropical climate.
Project Scope
Our company was selected as a key supplier for this initiative, providing high-quality line accessories, surge arresters, and air break switches. The supply contract covered both urban distribution lines in Lomé and rural electrification projects in northern Togo.
Key Products Supplied
Line Accessories
Tension clamps, suspension clamps, and strain fittings designed for 11kV and 33kV overhead lines.
Hot-dip galvanized steel and aluminum alloy materials for superior corrosion resistance in coastal areas.
Preformed armor rods to enhance conductor strength and reduce vibration.
Surge Arresters
Polymer-housed distribution-class arresters for 11kV and 33kV systems.
IEC 60099-4 compliant design to ensure stable performance in high lightning density zones.
Lightweight and maintenance-free design for ease of installation.
Air Break Switches (ABS)
Outdoor 11kV/33kV gang-operated switches with manual and motorized operation options.
Silver-plated contacts for improved conductivity and longer service life.
Fully tested according to IEC 62271 standards.
Challenges
Logistics & Customs: Togo’s port clearance process required careful coordination to ensure timely delivery.
Climate Considerations: Products had to withstand high humidity, heavy rainfall, and extreme heat.
Grid Compatibility: Ensuring that all supplied equipment matched the existing network design and protection settings.
Solutions
We pre-packed goods in modular batches to align with installation schedules.
Applied special anti-corrosion coatings to metal parts for extended service life.
Provided on-site training for Togo Electric’s technical team on installation and maintenance.
Results
The upgraded distribution lines showed a 30% reduction in outage frequency during the first rainy season after installation.
Surge-related equipment damage dropped significantly due to the new arresters.
The air break switches improved network sectioning and allowed faster fault isolation, minimizing service interruptions.
Conclusion
The successful supply and implementation of line accessories, surge arresters, and air break switches contributed significantly to Togo’s grid modernization efforts. Our tailored solutions and reliable delivery helped the Togo Electric Power Company meet its project goals, laying the groundwork for a safer and more stable power supply across the country.
