Customized Design and Application Range

With capacities from 100 kVA to 2500 kVA, these transformers feature customizable output voltages, robust three-phase operation, and can be configured with either copper or aluminum windings. Their construction ensures efficient, reliable power transfer suitable for industrial, commercial, and utility-scale applications.

FAQs of Dry Type Transformer:

Q: How do I select the appropriate dry type transformer for my application?

A: To select the right dry type transformer, determine your required capacity (1002500 kVA), voltage levels (11 kV/0.433 kV), installation environment (indoor or outdoor), and preferred features such as tap changer type or winding material. Our expert team can provide tailored recommendations based on your distribution needs and operational specifications.

Q: What benefits does Class F/H insulation provide in these transformers?

A: Class F and Class H insulation allows the transformer windings to handle higher temperatures (up to 100C hotspot), extending service life and reliability. This makes them ideal for demanding industrial environments where temperature resilience is crucial.

Q: When should I choose an on-load tap changer (OLTC) instead of an off-circuit tap changer?

A: An OLTC is suitable when voltage adjustments are needed while the transformer is energized and under load. Choose an off-circuit tap changer if manual voltage regulation is sufficient and can be done during maintenance intervals when the transformer is de-energized.

Q: Where can these dry type transformers be installed?

A: These transformers are designed for both indoor and outdoor use, thanks to their robust enclosure (IP23/IP44 protection) and adaptable mounting. They are ideal for facilities such as industries, commercial complexes, substations, and utility distribution points.

Q: What process is involved in manufacturing these transformers to meet IS/IEC standards?

A: Our manufacturing process includes sourcing high-grade silicon steel, precision winding of copper/aluminum coils, rigorous quality testing for dielectric and surge endurance, and assembly under strict performance standards (IS 11171/IEC 60076). Each transformer is uniquely configured and tested before shipment.

Q: How does air-cooled (AN/AF) technology benefit these transformers?

A: Air-cooled technology (using natural or forced air) provides effective and maintenance-friendly cooling, maintaining optimal operating temperatures without the need for liquid-based cooling systems. This reduces maintenance costs and enhances operational safety.

Q: What are the key advantages of using your dry type transformers for power distribution?

A: Key benefits include high efficiency (98%), robust safety and surge protection, adaptability for different mounting and locations, low operational noise, flexible voltage management, and compliance with global standards, ensuring reliable performance and long service life.
