On site construction of bare conductors in Guinea

Due to poor local transportation conditions, there are many simple roads with sandy/red soil, making it difficult to transport equipment for cable trench construction; Population dispersion and difficulty in material supply; In addition, after the completion of the remote rural power grid, the maintenance personnel and parts supply cycle are long, so the customer chooses corrosion-resistant AAAC bare wires.

        
The adaptation advantages of AAAC bare wire: The overall weight of AAAC bare wire is much lower than that of ACSR with the same current carrying capacity, lightweight, and suitable for construction in narrow streets and alleys; No steel core, wind resistant, sand and salt spray corrosion suitable for local environmental characteristics; High temperature resistance and stronger current carrying capacity.

       
This project adopts AAAC all aluminum alloy bare wire as the 0.4kV low-voltage overhead main line, and is equipped with newly built prefabricated cement poles. It is carried out with high-altitude operation vehicles and aluminum alloy zigzag ladders for pole laying, hardware installation, and wire tightening construction, completing the renovation of the old distribution network in the entire residential area. The entire construction process of manual ladder climbing, vehicle mounted high-altitude bucket arm truck pole operation, and tool transportation was recorded on site.
