Pyigyidagon 66 kV Line Project – Reinforcing Mandalay’s Electricity Backbone
Yaung Ni Oo Electric completed Phase 2 of the Pyigyidagon 66 kV line project—the installation of seventy (70) 22 m concrete poles on the Daung Yoe – Industrial Zone (1) corridor. The upgrade enhances line reliability, improves clearances, and supports growing demand from industrial and residential consumers across Pyigyidagon Township.
This program is part of a broader effort to bolster electricity distribution in Myanmar, reducing outage risk and improving power quality along a key 66 kV route feeding Mandalay’s production zones.
Schedule, Planning, and HSE
Delivered within 120 working days and 960 total hours, the project succeeded through disciplined planning, close coordination with stakeholders, and robust health, safety, and environmental (HSE) controls.
Key planning actions included:
- Early site surveys and foundation design for varied soil conditions
- Staged procurement to ensure continuous pole and hardware availability
- Crew sequencing (civil, erection, stringing) mapped to a critical path schedule
Despite rainy-season logistics and site-access constraints, the field teams maintained progress through weather-aware task sequencing and daily toolbox briefings.
Turnkey Scope & Technical Works
Under a full turnkey model, Yaung Ni Oo Electric executed end-to-end engineering and construction activities:
- Civil works: survey, route setting, excavation, reinforced concrete foundations, backfilling, and compaction
- Pole erection: lifting, alignment, and plumb verification for 22 m RC poles (70 Nos)
- Hardware & accessories: crossarms, insulators, brackets, stay sets, and line hardware to utility specifications
- Conductor readiness: stringing prep, sectioning plans, and sag/tension design (per 66 kV requirements)
- Protection & safety: earthing at pole locations where specified, work-at-height controls, energized-network proximity procedures
- Testing & documentation: inspections, punch-list clearance, and as-built records
Materials and workmanship were controlled against national and international standards, ensuring long-term durability and safety.
Handover and Operational Readiness
Upon completion, the works were inspected, verified, and formally handed over to MESC (Mandalay Electricity Supply Corporation). The handover package included as-built drawings, test reports, material certificates, and O&M guidance for ongoing maintenance.
Community & Industrial Benefits
The strengthened corridor delivers immediate and long-term benefits:
- Higher reliability and reduced outage frequency for Industrial Zone (1) and nearby communities
- Improved voltage profiles and capacity to support load growth
- A sturdier network backbone resilient to weather and operational stresses
These outcomes advance electricity distribution in Myanmar and support Mandalay’s industrial development and livelihoods.
