Project Highlights
- Scope: 33 kV overhead distribution line (turnkey) — Hsihseng → Naung Yindong
- Purpose: Extend national grid supply to villages in the Pa-O Self-Administered Zone and improve reliability
- Timeline: 180 days / 1,440 hours
- Impact: Stronger backbone for electricity distribution in Myanmar across Hsihseng Township
Hsihseng 33 kV Line Project — Extending Reliable Power to Naung Yindong
The Hsihseng 33 kV line project was executed to connect Hsihseng with Naung Yindong, expanding dependable grid access for villages in southern Shan State. The line enables stable supply for homes, schools, clinics, and small businesses while reducing outages caused by long radial feeders and seasonal weather.
This investment supports regional development priorities by improving voltage profiles, cutting technical losses, and creating capacity headroom for future connections across the corridor.
Planning & Schedule (Delivered in 180 Days)
To achieve completion within 180 days (1,440 total hours), a multidisciplinary team—planning, surveying, civil, electrical, HSE—sequenced works to maintain the critical path through the rainy season. Long-lead materials (poles/structures, insulators, hardware, conductors) were staged ahead of time. Daily coordination meetings and toolbox talks kept productivity high and risks controlled.
Turnkey Scope & Technical Works
Delivered as a full turnkey EPC, the project covered end-to-end activities:
- Survey & Design: route alignment, structure spotting, span & sag/tension calculations for the 33 kV corridor; clearance checks to utility/IEC practices.
- Civil Works: excavation, reinforced concrete foundations, earthing at structures, drainage and access improvements suitable for hilly terrain and monsoon flow.
- Line Erection & Stringing: poles/towers, crossarms, insulators, hardware fitting, conductor stringing with calibrated tension; sectioning plans for controlled energization.
- Interfaces & Protection: terminations at the Hsihseng and Naung Yindong ends; protection coordination, relay setting review, and phasing checks.
- Testing & Commissioning: mechanical completion, insulation resistance tests, line patrolling, punch-list clearance, and as-built documentation (drawings, test reports, material certificates).
All materials and workmanship complied with national and international quality standards, ensuring durable performance for electricity distribution in Myanmar.
Managing Terrain, Weather, and Logistics
The corridor crosses rural roads and undulating terrain where monsoon rains can limit access. The team mitigated risks by:
- Re-sequencing foundations and stringing around heavy-rain windows,
- Using temporary access pads and barricades near public routes,
- Coordinating deliveries to maintain continuous work fronts,
- Enforcing strict work-at-height and energized-network proximity procedures.
These measures kept the Hsihseng 33 kV line project on schedule without compromising safety or quality.
Community & System Benefits
With commissioning complete, households and businesses along the Hsihseng–Naung Yindong corridor benefit from:
- More reliable service and fewer outages,
- Improved voltage during evening peaks,
- Lower losses and better operational flexibility for the utility,
- A stronger platform for education, health services, agro-processing, and local commerce.
