Project Highlights
- Scope: 33 kV ACSR 477MCM installation (turnkey EPC)
- Location: Waw Township, Bago Region (East), Myanmar
- Timeline: 180 days / 1,440 hours
- Impact: Stronger backbone for electricity distribution in Myanmar, serving Waw town and surrounding villages
Waw 33 kV Line Project — Why This Upgrade Matters
The Waw 33 kV line project increases feeder capacity and stabilizes voltage for Waw Township and nearby communities. By rebuilding the overhead line with ACSR 477MCM, the corridor now supports higher current, improved voltage profiles, and lower technical losses—reducing outages for households, markets, clinics, and small industries across Bago (East).
Planning, Schedule, and Risk Controls (180 Days)
To complete the Waw 33 kV line project within 180 days (1,440 hours), Yaung Ni Oo Electric assembled a multidisciplinary team—engineers, technicians, and skilled crews—sequenced to keep the critical path moving through the rainy season. Long-lead materials (conductors, insulators, fittings) were staged early.
Daily toolbox talks, traffic management during stringing, and energized-network proximity procedures kept HSE performance high while maintaining productivity.
Turnkey Scope & Technical Works
Delivered under a full turnkey contract, the scope covered end-to-end EPC:
- Survey & design: route confirmation, structure spotting, and sag/tension calculations for ACSR 477MCM conductors; clearance checks to utility/IEC practices.
- Civil works: excavation, reinforced concrete foundations, earthing, access tracks, and drainage to suit monsoon conditions.
- Erection & stringing: structures, crossarms, insulators, hardware fitting, conductor stringing with calibrated tension; sectioning plans for safe energization.
- Interfaces & testing: terminal connections at feeder ends, protection coordination with ESE, mechanical completion checks, IR tests, line patrolling, and commissioning.
- Documentation: QA/QC records, material certificates, as-built drawings, and O&M guidance for long-term reliability.
All materials and workmanship complied with national and international quality standards, ensuring durable performance for electricity distribution in Myanmar.
Managing Monsoon & Logistics
Construction coincided with the rainy season and rural-road access constraints. The project mitigated risks by:
- Re-sequencing foundations and stringing around weather windows,
- Using temporary access pads and traffic control where required,
- Coordinating deliveries to keep continuous work fronts open.
These measures kept schedule and quality intact without compromising safety.
Results for Waw Township and Surrounding Communities
Commissioning the upgraded feeder delivers immediate and long-term benefits:
- Higher reliability and fewer interruptions for Waw households and services,
- Improved voltage and additional capacity for load growth,
- Reduced technical losses and smoother utility operations,
- A sturdier regional network underpinning commerce, transport, and public facilities in Bago (East).
