Key Safety and Control Features of Our Transformers
BPIL transformers are not only reliable but also engineered with advanced safety systems. To protect your investment and ensure uninterrupted power supply, each of our transformers incorporates the following protection and control features:
- On-Load Tap Changer (OLTC): This mechanism allows the transformer to change voltage ratios while under load, ensuring stable voltage supply during fluctuations.
- Off-Circuit Tap Changer (OCTC / Off-Load Tap Changer): This mechanism allows voltage adjustments when the transformer is de-energized or not under load, crucial for setting the correct voltage for various load conditions.
- Buchholz Relay: An essential safety device, it detects internal faults such as short circuits, insulation failures, or excessive oil heating, automatically issuing an alarm or tripping the transformer.
- Expansion Valve: As oil temperature rises, its volume expands. The expansion valve safely releases this excess pressure, preventing structural damage to the transformer.
- Pressure Relief Device (PRD): Used to quickly and safely reduce internal pressure build-up within the transformer, thereby minimizing the risk of explosion.
- Oil Temperature Indicator (OTI) & Winding Temperature Indicator (WTI): These indicators continuously monitor the oil and winding temperatures of the transformer. They provide alerts if temperatures exceed safe limits, protecting against overloading or overheating.
- High Quality and Safety Standards: All our transformers are manufactured in strict compliance with international IEC (International Electrotechnical Commission) standards and Bangladesh’s BPS (Bangladesh Standards), along with all other relevant safety and quality benchmarks.
Evolution of Transformer Technology & BPIL's Role
Transformer technology has seen significant advancements in recent decades, particularly in energy-efficient designs and improved safety features. Since 2000, there has been a global emphasis on increasing transformer efficiency, leading to a substantial reduction in iron loss and copper loss. BPIL keeps pace with these global changes, consistently adopting modern and energy-efficient designs that reduce your electricity costs and contribute to environmental protection. We are proud that our transformers are making Bangladesh’s power distribution system more reliable and efficient.
World-Class Raw Materials Used in Our Transformers
BPIL never compromises on quality. To build the best transformers, we source raw materials from leading global suppliers. These high-quality components ensure the long-lasting performance, high efficiency, and maximum safety of our transformers.
- Core: For the core, we use silicon steel from JFE, Japan, and Nippon Steel. These cores feature extremely low losses and high magnetic properties, enhancing transformer performance and minimizing power wastage.
- Insulating Materials: For insulation, we utilize high-quality insulating materials, specifically ABB (Ramon boards) from Italy. These materials maintain the transformer’s internal dielectric strength and increase its heat resistance.
- Transformer Oil: We use transformer oil from Savita, India, and Hyrax, Malaysia. These oils serve as both cooling and insulating mediums within the transformer and maintain stability at high temperatures.
- Super Enamelled Copper Wire: For windings, we use super enamelled copper wire from renowned Bangladeshi companies, Gazi and BRB. These wires possess high conductivity and excellent insulation properties, ensuring the transformer’s longevity and high efficiency.
