Location Between Jahrom, Larstan, and Gerash counties
Stage Provisional delivery

Technical Specifications

•    Line length: approximately 167 km
•    Route passes mainly through rugged mountainous terrain
•    Entire project completed with a diverse combination of lattice towers adapted to site conditions

Moshanir responsibility:

Moshanir provided engineering services including:
•    Route selection and surveying
•    Preparation of plan and profile drawings
•    Engineering studies
•    Geological and geotechnical investigations
•    Tower spotting and layout
•    Preparation of tender documents and contracts for procurement and execution

Key Achievements

•    Successful implementation of the project using a diverse mix of lattice towers, achieving the lowest possible cost among comparable transmission lines
•    Despite the line being designed as a triple bundle conductor, tension insulator strings were applied in double configuration, optimizing cost and performance
