Annual substation maintenance service in Bangladesh

When it comes to power, most people only think about what happens when the lights go out. But the truth is, avoiding that blackout starts long before. Substations are the backbone of every industrial plant, real estate project, or government facility in Bangladesh. They quietly handle the heavy lifting—day after day.

Even the most expensive equipment can fail without proper care. That’s where annual substation maintenance service makes all the difference. AB Power Engineering Ltd. has spent over 18 years ensuring substations across Bangladesh run safely and efficiently.

AB Power Engineering Ltd. offers all types of annual maintenance contracts. Contact us today to secure your annual substation maintenance contract.

Our annual substation maintenance services

Every substation is different, but the checklist we follow is broad enough to cover every critical part. Our team doesn’t just tick boxes. We share detailed reports, so you know what’s working fine and what needs attention.

Power Transformer
Transformer Maintenance

We perform oil testing, load monitoring, and filter changes. A small action like cleaning can stop big problems like overheating.

Circuit Breaker & Switchgear Servicing
Circuit Breaker & Switchgear Servicing

Breakers and panels are opened, tested, lubricated, and faulty items are replaced. Without this, a single fault will result in a total stop.

Protection System & Relay Calibration
Protection System & Relay Calibration

Relays are tested and recalibrated to ensure they trip exactly when they’re supposed to work.

Cable & Busbar Inspection
Cable & Busbar Inspection

We test insulation, secure joints, and thermal images to detect invisible hot spots.

General Substation Health Check

Importance of annual substation maintenance

If a substation shuts down suddenly, production lines freeze, and hours of work get lost. The repair bill? The price is usually much higher than the cost of a scheduled service. Annual maintenance keeps your system in shape. Explore why annual maintenance is important for substations:

  • Prevents sudden breakdowns.
  • Keeps transformers, breakers, and relays running at optimum performance.
  • Ensures compliance with BPDB safety rules.
  • Extends the lifespan of equipment that otherwise wears down faster in our humid climate.
