Project Highlights
- Scope: 33 kV ACSR 477 MCM installation (turnkey) on the Yekyi–Danubyu corridor
- Location: Danubyu Township, Ayeyarwady Region (ESE)
- Timeline: 180 days / 1,440 hours
- Impact: Stronger backbone for electricity distribution in Myanmar, serving Danubyu and nearby villages
Danubyu 33 kV Line Project — Upgrading a Critical Feeder
Yaung Ni Oo Electric delivered the Danubyu 33 kV line project to expand capacity and stabilize the Yekyi–Danubyu distribution corridor. By replacing and rebuilding sections with ACSR 477 MCM, the line now supports higher current carrying capability, improved voltage profiles, and reduced outages for households and businesses across Danubyu Township.
Planning, Schedule, and HSE
Completion in 180 days (1,440 hours) required careful sequencing through the rainy season. Prior to mobilization, a multidisciplinary team of engineers, technicians, and skilled crews was formed, while long-lead materials—conductors, insulators, hardware—were staged to maintain the critical path.
Daily toolbox talks, traffic control during stringing, and proximity procedures near energized assets kept safety and quality front-and-center throughout delivery.
Turnkey Scope & Technical Works
Executed as a full turnkey contract, the project covered end-to-end EPC tasks:
- Survey & design: route confirmation, structure spotting, and sag/tension calculations for ACSR 477 MCM
- Civil works: excavation, reinforced concrete foundations, earthing, access and drainage improvements
- Erection & stringing: structures, crossarms, insulators, fittings, and conductor stringing with calibrated tension; sectioning plans for safe energization
- Interfaces & testing: terminal connections at feeder ends, protection coordination with ESE, mechanical completion, patrolling, IR tests, and commissioning
- Documentation: QA/QC records, material certificates, as-built drawings, and O&M guidance
All workmanship complied with national and international quality standards, ensuring long-term performance for electricity distribution in Myanmar.
Managing Seasonal & Logistics Constraints
Monsoon conditions and river-delta access posed transport and site-stability challenges. The project team mitigated risks by re-sequencing activities around weather windows, using temporary access mats where needed, and coordinating deliveries to maintain continuous workfronts—keeping the Danubyu 33 kV line project on schedule without compromising HSE.
Results for Danubyu & Surrounding Communities
With commissioning complete, the upgraded feeder provides:
- Higher reliability and fewer interruptions for Danubyu Township
- Improved voltage and capacity to support load growth
- Lower technical losses and smoother operations for the utility
- A sturdier network supporting commerce, services, and community facilities
