📍 Azito–Boulay 400 kV Transmission Line | Abidjan, Ivory Coast

We are proud to share the completion of Ivory Coast’s first Extra High Voltage (EHV) 400 kV transmission corridor, a landmark project designed to increase power transfer capability while improving overall grid efficiency and reliability as demand rises around Abidjan and surrounding load centers.

The Azito–Boulay line features a 36 km installation of ACCC® ULS Monte Carlo Conductor in a 400 kV triple-bundle configuration with overhead earth wires—selected to optimize corona performance, reduce line reactance, and increase thermal capacity for this new backbone EHV line.

Project Details:
• 36 km of ACCC® ULS Monte Carlo Conductor installed in a 400 kV triple-bundle configuration
• ~1,600 m river (lagoon) crossing, completed using a multi-span approach and 20 individual pulls
• EPC contractor: Eiffage Energy Systems
• Conductor supplier: Apar Industries

This installation marks a major step forward for Ivory Coast—delivering more power with lower losses and greater reliability, while demonstrating the value of Advanced Conductor technology for EHV applications in challenging, warm coastal environments.
