Moon Lake Electric Association requested a design to replace the existing 23.5-mile 69 kV Jensen-Dinosaur line. The new line, like the existing line, is a wood pole line consisting predominantly of monopole structures. Wood H-Frame and three-pole structures are utilized for 2.7 miles between the Jensen station and the Green River on the west end of the line. Additionally, wood H-Frame and three-pole structures are utilized in other portions of the line where terrain dictates longer spans and for the transition into the MAPCO station.
The conductor for the line is 4/0 ACSR “Penguin” with 477 kcmil 26/7 Strands ACSR “Hawk” in 3 spans at the crossing of the Green River. The line is shielded by an AFL 48-fiber OPGW. The line includes a drop into the MAPCO station which involves replacing the main station wood pole H-frame structure while reutilizing the existing equipment on the structure. The line also includes a new three-way phase-over-phase switch at the Dinosaur Tap.
