Electrical power distribution plan for the Et Tiri Tunnel Inlet Portal in Lebanon, part of the Hydro Agricultural Development of South Lebanon irrigation project. The drawing illustrates the power system configuration with a 53kVA, 15kV/400V transformer that converts power from EDL (Électricité du Liban) 15kV network to 400V three-phase and neutral supply. The power panel labeled ‘LP-TT’ distributes electricity throughout the facility.
The drawing clearly demarcates the limit of supply responsibility between the contractor and EDL, with coordinates displayed on a grid system. The power single-line diagram shows the electrical distribution hierarchy from the utility connection point through the transformer to the main distribution panel. This electrical installation drawing was prepared for Contract 3 of the Conveyor 800 project and is scaled at 1:200, with a clear indication that it was prepared for construction purposes.
