Medium voltage overhead cables assist in the application of urban road power in West Africa
The characteristics of medium voltage overhead cables: their safety is much better than bare wires, and they are suitable for villages, residential areas, and tropical regions with more vegetation; Compared to underground cables in cable trenches, it has lower cost and faster construction, without the need for large-scale excavation, pipeline laying, and backfilling. Relying on galvanized steel poles for installation, the amount of civil engineering work is small; The total cost of materials and construction is significantly lower than that of buried medium voltage cables, making it suitable for large-scale rural power grid construction; Convenient operation and maintenance; Flexible expansion and line modification; Good anti-corrosion adaptability (matched with hot-dip galvanized steel poles).
This project implements the construction of an Overhead Medium Voltage (MV) Transmission Line, deployed in a rural area of West Africa. The scheme adopts hot-dip galvanized polygonal steel utility poles to support overhead medium voltage cables, to build a stable power transmission network for local settlements. The construction covers foundation casting of steel poles, pole erection, overhead cable installation, commissioning and acceptance, to solve the local power supply shortage and improve the reliability of regional power infrastructure.
The project site features tropical vegetation, laterite soil, scattered farmland and residential settlements. Limited local transportation conditions require pre-transporting galvanized steel pole components to construction sites. High temperature and rainy tropical climate bring strict requirements for foundation construction quality and anti-corrosion performance of line equipment.
The overhead medium voltage cable solution is a practical, economical choice for rural electrification in tropical regions. With standardized foundation construction and strict site management, the overhead MV line achieves stable power delivery, effectively improving local power access
