Products Power Conversion Engineering Fully compliant with Bangladesh Power Development Board (BPDB) standards, custom engineered for severe tropical humidity, high ambient heat, and continuous grid stability.
Addressing the unique climatic, grid-code, and industrial challenges of Bangladesh’s rapid energy sector expansion.
Bangladesh’s ready-made garment (RMG) hubs in Gazipur, Narayanganj, and Chattogram demand continuous, harmonic-free power. Our SCB10/13 dry-type transformers feature zero-fire-hazard epoxy encapsulation, ensuring safe indoor operation within multi-story spinning, weaving, and dyeing factories.
As Bangladesh develops 100 Special Economic Zones (such as Mirsarai Economic Zone), our medium and high-voltage power transformers (up to 230kV 50MVA) provide robust step-down transmission for heavy industries, steel rolling mills, and chemical processing complexes.
For rural electrification (BREB) and urban utilities (DPDC, DESCO, BPDB), our oil-immersed S11-M and S13-M series offer ultra-low no-load losses, withstand heavy lightning surges during monsoon months, and reduce line drop across long 33kV/11kV distribution feeders.
Bangladesh Grid Compatibility Guarantee: Every unit shipped to Bangladesh is engineered to withstand ambient summer temperatures exceeding 45°C, relative humidity levels above 90%, and seasonal monsoon tropical storm conditions. Outer tanks receive C5-M marine-grade multi-layer anti-corrosion coating to prevent saline atmosphere degradation near coastal zones like Chattogram, Khulna, and Cox’s Bazar.
Strategic modernization trends shaping utility procurement, environmental safety, and energy conservation.
In response to the Bangladesh Sustainable and Renewable Energy Development Authority (SREDA) guidelines, power distribution companies are phasing out legacy high-loss transformers. Modern S13-M and S20-M fully-sealed transformers feature wound-core technology that reduces no-load loss by up to 30% and load loss by 15%, significantly diminishing operational carbon footprints and operational expenditures for factory owners.
With strict fire safety mandates enforced in Dhaka and Chattogram metro areas, commercial real estate developers and industrial plant managers are replacing conventional oil-filled units with F-class or H-class cast resin dry-type transformers (SCB10/13 series). These units eliminate oil-leakage risks, are non-flammable, and require minimal maintenance inside underground sub-stations.
Utility-scale solar farms across Bangladesh (e.g., Teknaf, Sundarganj) require specialized step-up transformers capable of handling reverse power flows, fluctuating voltage inputs, and severe solar inverter harmonics. Our step-up oil transformers are custom-wrapped with electrostatic shielding between primary and secondary windings to preserve grid quality.
As PGCB transitions toward digital substations and automated SCADA networks, our high-voltage transformers (110kV to 230kV) come equipped with micro-processor controlled On-Load Tap Changers (OLTC) and online dissolved gas monitoring (DGA) interfaces for real-time asset health tracking.

Combining 60+ years of power engineering legacy with ISO-certified production lines and flexible custom design tracks.
Whether your project calls for standard catalog ratings or specialized modified-standard configurations (such as custom vector groups, dual-voltage tapping, low-noise enclosures, or specific busbar dimensions), our design engineers deliver accurate preliminary engineering drawings prior to production.
Engineered to operate reliably under extreme ambient conditions ranging from -55°C to +125°C. Utilizing superior magnetic core materials, high-purity electrolytic copper, and specialized potting or conformal coatings, our transformers thrive where lesser equipment suffers thermal breakdown.
Our designs adhere strictly to international standards including IEC 60076, ANSI C57, IEEE, UL/IEC 60601-1, MIL-STD specifications, CISPR/EN 55032 emissions limits, and Bangladesh BSTI/BPDB qualification requirements.
Key information regarding testing, BSTI/BPDB approval, customs clearance, and logistics to Chattogram Port.
Yes. Every power transformer manufactured for Bangladesh undergoes full routine testing (winding resistance, voltage ratio, phase displacement, short-circuit impedance, load loss, no-load loss, and insulation resistance) according to IEC 60076. Type test reports (lightning impulse withstand and temperature rise tests) conducted by accredited third-party laboratories (KEMA/ILAC) are available upon request.
Our oil-immersed transformers use hermetically sealed corrugated metal tanks that completely isolate the transformer oil from ambient oxygen and humidity. This prevents moisture ingress, preserves oil dielectric strength (>60kV), and eliminates routine oil maintenance. Exterior surfaces receive a sandblasted C5-M anti-corrosion primer and polyurethane topcoat.
Standard distribution transformers (100kVA–2500kVA) are produced within 20–30 days after drawing approval. Transit time via maritime freight from our main manufacturing port to Chattogram (Chittagong) Port is typically 12 to 18 days. Complete shipping documentation (Bill of Lading, Certificate of Origin, Form C, Packing List, and Factory Test Certificates) is dispatched promptly to facilitate smooth customs clearance.
Yes. We routinely manufacture distribution and power transformers with Dyn11, Ynd11, Yyn0, or custom phase-displacement vector configurations required by local Bangladeshi electrical consultants and utility specifications.
Whether you need standard distribution transformers for an industrial project in Dhaka or custom 230kV power transformers for a PGCB substation tender, our applications team is ready to assist with technical specs, drawings, and instant quotations.
