Types of Transformers we supply in Bangladesh

Transformer selection normally starts with the application. Capacity comes after that. Different projects need different transformer ratings and designs. A small commercial building, a factory, and a large substation will not use the same transformer. AB Power Engineering Ltd. supplies a wide range of power transformers and provides electrical goods and services & solutions across Bangladesh.

Oil-immersed power transformer

Oil-immersed power transformers are widely used in substations and industrial plants as well as heavy electrical networks.

33/11kV power transformer

A 33/11kV power transformer is used for stepping down voltage for industrial, commercial, or distribution purposes and is widely used in substation projects.

Industrial power transformer

Factories, production plants, cold storage facilities, textile units, steel plants, and large machinery-based businesses need stable power.

Distribution transformer

Distribution transformers are used to deliver usable voltage to buildings, communities, factories & commercial areas.

Dry-type transformer

Dry-type transformers are suitable for indoor spaces, hospitals, high-rise projects, and places where oil-based transformers may not be preferred.

Custom transformer for substation projects

Every substation project is different. Some projects need special ratings, specific protection systems, or space-friendly designs.

Transformer with OLTC

Transformers with an on-load tap changer, or OLTC, help to adjust voltage while the transformer remains in operation. This is useful for projects where voltage fluctuation is common.

Three-phase transformer

It’s used in most industrial and commercial power systems. They are suitable for heavy loads, motors, HVAC systems, lifts & large electrical installations.

Isolation transformers

It helps protect sensitive equipment from electrical disturbances and improve power quality. Applications include data centers, medical facilities, laboratories & industrial control systems.

Technical specifications of our transformers

Transformer data should be clear before a purchase order is placed. Capacity alone is not enough. Voltage ratio, cooling, winding specification, installation condition, tap arrangement and accessories all affect the final design. Our transformer manufacturing information includes the following:

Technical area	Available/project specification
Manufacturing capacity	100 kVA to 20 MVA
Voltage ratings	33 kV / 11 kV / 0.415 kV / 0.240 kV
Frequency	50 Hz
Configuration	Three-phase
Common construction	Oil-immersed
Cooling	ONAN
Installation	Project/site dependent
Tap arrangement	Off-load or project-specific arrangement
Transformer accessories	Based on approved technical specification
Testing	Routine factory testing before dispatch
Manufacturing	Manufactured and assembled in Bangladesh

Note: The final specification is prepared against the actual project. For example, a 1,000 kVA 11/0.415 kV industrial transformer cannot simply be treated as a smaller version of a 33/11 kV MVA-class substation transformer.

Transformer price in Bangladesh

There is no useful single price for every transformer in Bangladesh. A 500 kVA distribution transformer and a multi-MVA 33/11 kV unit differ heavily in material, engineering, accessories and project scope. Usually, each transformer costs from BDT 80 thousand to BDT 16 lakh. The quotation normally changes according to:

Cost factor	Why it matters
Transformer capacity	Higher kVA or MVA normally requires more material and a larger unit
Voltage rating	11 kV and 33 kV designs have different insulation and engineering requirements
Winding specification	Material and approved winding design affect cost
Transformer type	Construction and cooling arrangement change the manufacturing cost
Tap changer	Off-load and OLTC requirements are different
Accessories	Protection, indication and monitoring requirements vary by project
Quantity	Multiple-unit industrial projects are quoted differently
Transportation	Delivery location and handling requirements affect project cost
Installation	Supply-only and installed prices are not the same
Testing & commissioning	Site testing and commissioning scope is quoted separately where applicable

How we select the right transformer capacity

Buying extra capacity without a reason increases the project cost. Going too small creates a different problem. The transformer may operate close to its limit, run hot or leave no room when new machinery is added.

Before finalizing a transformer, we look at the connected electrical load, expected operating load, motor starting demand, incoming voltage, future expansion, installation location, protection arrangement and the rest of the substation.

For an existing factory, we may also need to understand what is already operating on site. A new production line can change the load considerably. The goal is simple: install a transformer that fits the real electrical system, not just a kVA number written in an initial inquiry.

Supply, installation, testing & commissioning process

We provide transformer supply and installation support. Wrong handling, weak cable connections, poor earthing, or incomplete testing can create serious electrical risks. Our process is planned to keep the project safe and organized from selection to energization. Our general process includes:

Project and load review

We first check what the transformer will supply. Existing load information, proposed machinery, voltage level and future expansion are reviewed.

Technical specification analysis

Capacity, voltage ratio, transformer type, tap arrangement, installation condition and required accessories are confirmed according to the project.

Manufacturing or supply planning

Once the technical requirement is approved, the transformer is planned according to the agreed specification and delivery scope.

Factory inspection and testing

The completed transformer goes through the required factory checking and routine testing before dispatch.

Delivery and installation

The transformer is transported to the project location. Installation, positioning, earthing, cable termination and associated electrical work are coordinated according to the agreed scope.

Testing and commissioning

Before energization, the transformer and related substation system are checked. Commissioning is completed only after the required site conditions are ready.

Maintenance support

Transformer performance does not end at commissioning. We also provide annual maintenance and electrical maintenance support for operating power systems.

FAQs about transformer manufacturing in Bangladesh

These FAQs answer common questions about power transformer price, 33/11kV transformers, dry-type transformers, installation, commissioning, and maintenance support in Bangladesh.

Choosing the right transformer capacity starts with your actual electrical load. Check connected equipment, motor starting current, maximum demand, operating hours and any future expansion. Do not select kVA only from the current load. A proper load calculation helps avoid overloading, voltage problems and unnecessary oversizing. For industrial projects, review the load schedule before finalizing the transformer size.

Published transformer ratings include 33 kV, 11 kV, 0.415 kV and 0.240 kV. Common industrial projects in Bangladesh include 11/0.415 kV transformers, while larger substation projects may use 33/11 kV arrangements.

Industrial projects usually need oil-immersed or three-phase power transformers, depending on load and site conditions. The right choice should be made after checking the machine load, voltage level, and future expansion.

A power transformer is generally used in high-voltage transmission or substation projects. A distribution transformer is used near the final load point to deliver usable voltage to buildings, factories, or local networks.

Yes. Routine tests are carried out before dispatch from the factory. Site testing and commissioning can also be included depending on the agreed project scope.

The capacity should be calculated from the actual connected and operating load, motor demand, future expansion and electrical distribution plan. If you are unsure, send us your load list, SLD or available project details for review.

Yes. Our work covers transformers as well as electrical substations, switchgear, installation, testing, commissioning and maintenance. This is useful for industrial clients that prefer one technical team coordinating the main power system.

Both can work when properly designed. Copper has higher conductivity. Aluminium needs a different conductor size and winding design. Follow the consultant or project specification where one is available.

এটা শুধু ফ্যাক্টরির আয়তনের ওপর নির্ভর করে না। মোট connected load, motor starting current, production machine, HVAC, pump এবং future load expansion হিসাব করে capacity নির্বাচন করা উচিত।

এই ধরনের step-down transformer সাধারণত factory, commercial building, warehouse এবং private substation-এ ব্যবহার করা হয়। এটি 11 kV supply কমিয়ে প্রায় 415 V distribution level-এ নিয়ে আসে।

দুই ধরনের winding-ই ব্যবহার করা যায়, যদি transformer design সঠিক হয়। Copper-এর conductivity বেশি, তবে aluminium winding-এর ক্ষেত্রেও conductor size ও design অনুযায়ী ভালো performance পাওয়া সম্ভব।
