Cable trays vary in size in order to accommodate varying numbers of wires. International projects are most often made in widths of between 50mm and 900mm and depths of between 50mm and 150mm. When choosing the size of cable tray, it is a tradeoff between the existing volume of cable and the future volume of cable. It is grounded on 40 years of experience in the manufacturing. In practice, cable tray dimensions are a system of interrelated measurements —width, depth, length, and material thickness—that directly affect cable fill compliance, heat dissipation, structural loading, and long-term expandability. Heights typically range from 25mm to 150mm, depending on cable volume and application requirements. In US practice per NEMA VE 1 (referenced by NEC. The B-Line series Cable Tray Manual was produced by our technical staff.
The project involves installing two 225 kV power cables offshore, spanning 16 kilometers each, and six two-kilometer 225 kV cables onshore, connecting Dakar's west and east coasts. In collaboration with our joint venture partner, Enshore Subsea, we joined forces under the Dakar Marine Link initiative to install two subsea power cables. The consortium is said to be a 50/50 joint venture between Eiffage's Benelux subsidiary Herbosch-Kiere and Enshore. Eiffage, through Herbosch-Kiere (Eiffage Benelux subsidiary) in a 50/50 joint venture with Enshore Subsea (a leading UK based subsea engineering company), has signed an EPCI contract with MCA-Sénégal II for the design, manufacture and installation of undersea electrical cables in Dakar, Senegal.
