Our distribution and transmission line installation in Nay Pyi Taw service delivers a complete, inspection-ready build from first peg to energized handover. Urban boulevards, expanding estates, and government districts demand lines that are mechanically robust, electrically efficient, and easy to maintain. We handle the whole lifecycle—route survey, engineering design, material supply, safe erection, quality control, and commissioning—so feeders and interconnects go live on schedule and stay reliable through monsoon seasons.
It starts with a disciplined survey. We walk the corridor, confirm right-of-way constraints, mark utilities, and assess access for cranes and stringing equipment. Span lengths, turning angles, river and road crossings, and vegetation zones are captured with GPS and photos. Soil conditions guide foundation choices for poles and towers; where ground is soft or seasonal, we specify deeper sockets, improved backfill, or guyed solutions. These findings are translated into a constructible alignment, minimizing future maintenance and avoiding surprises when crews mobilize.
Design converts field data into a safe, economical line. For distribution feeders (LV/MV), we select pre-stressed concrete poles with moment capacity suited to local wind and conductor tensions, and detail crossarms, pin/post insulators, and stay assemblies that match the conductor type. For transmission spans (HV), we model lattice or monopole towers with appropriate load cases and clearances, factoring in galloping risk and lightning density. Sag-tension is calculated across temperature and wind scenarios so ground and crossing clearances are preserved at worst-case conditions. Hardware is specified for corrosion resistance and UV stability; where lines run near public areas, we adopt covered conductor or ABC for safety and reduced outage risk.
Conductors and fittings are chosen for performance over the full life cycle. ACSR or AAAC is sized for ampacity, loss targets, and expected load growth; compression dead-ends and mid-span joints are matched to alloy and diameter, installed with calibrated dies, and sealed against moisture. Insulators—porcelain or polymeric—are selected to suit pollution class and creepage requirements, with arcing horns and surge arresters applied where overvoltage risk is elevated. Earthing is designed as a low-resistance network at structures, switches, and transformer points, verified later with measured values. The result is a line that runs cool under load and trips locally when a fault occurs, instead of cascading upstream.
Construction is managed to be tidy, safe, and fast. Foundations are poured to spec with proper cover and compaction; poles and towers are lifted using spreader bars, slings, and taglines that protect members and coatings. Stringing plans set up pilot lines, tensioners, and travelers to avoid conductor scuffing, and we schedule pulls to dodge the windiest hours. At road and canal crossings, temporary guards and traffic coordination keep the public safe while we complete pulls and clipping. Crews work to a method statement that defines exclusion zones, hand signals, LOTO (lock-out/tag-out) at tie-in points, and rescue plans for working at height—because safe sites stay on schedule.
Quality control is continuous, not a single punch-list at the end. We check pole plumb, tower bolts and torque, guy tensions, crossarm levels, and insulator orientation as we go. After stringing, we verify sag with theodolites or calibrated methods, measure clearances, and inspect every compression fitting for witness marks. At substations and recloser points, we confirm phase sequence, CT/VT orientation, and protection settings, and we label equipment so operators can isolate a section quickly during faults or maintenance. Documentation includes as-built alignment sheets, structure schedules, torque logs, earthing results, and photo records tied to structure IDs.
Commissioning is a written, witnessed sequence. We perform insulation resistance checks, continuity and phase verification, and step-and-touch potential assessments at earthing points. Protection is tested end-to-end so feeder faults trip at the right device with discrimination, and live energization is staged—section by section—to prove stability. Only when the line runs quietly under load and telemetry is clean do we hand over.
Because policy and expectations evolve, we align designs and procedures with recognized power-line good practice while tracking domestic guidance.

Grounding methods, documentation, and labeling conventions benefit from anchoring to authoritative sources, which keeps approvals and audits straightforward in Nay Pyi Taw.
Costing remains transparent. Your proposal separates poles/towers, foundations, conductors, insulators, fittings, stays/guys, earthing, hardware, and labor, with options for corrosion classes and conductor upgrades. Logistics reflect real access—staged deliveries, laydown areas, and traffic management—so the schedule is realistic. The outcome is simple but powerful: a distribution or transmission line that is structurally sound, electrically efficient, clearly documented, and ready for safe operation across Nay Pyi Taw’s growing network.
