Dry Type Transformer Manufacturer & Supplier in India

Supplying High-Performance Dry Type Transformers from 100 KVA to 2500 KVA — Trusted by Industries Across India

What Is a Dry Type Transformer?

A Dry Type Transformer is an energy-efficient, oil-free transformer that uses air or solid insulation materials — such as epoxy resin or NOMEX — instead of liquid for cooling. Unlike conventional oil-filled transformers, dry-type units eliminate the risk of oil leaks, fire hazards, and environmental contamination, making them the preferred choice for indoor installations, commercial buildings, hospitals, data centres, and industrial facilities.

Tirupati Transformers Pvt. Ltd. is among the top 10 Dry Type Transformer manufacturers in India, delivering precision-engineered transformers that meet international safety and efficiency standards.

Also explore our Cast Resin Transformer and VPI Transformer — both are advanced variants of dry-type technology.

Why Choose a Dry Type Transformer Over Oil-Filled Transformers?

Zero Fire Risk and Explosion Hazard

Dry-type transformers contain no flammable liquids, making them inherently safe for enclosed spaces, underground installations, high-rise buildings, and areas with strict fire safety regulations — a critical advantage over conventional oil-type transformers.

Environmentally Safe and Low Maintenance

With no oil involved, there is zero risk of environmental contamination from leaks or spills. Dry-type units also require significantly less maintenance over their operational lifespan, reducing your long-term costs.

Reliable in Humid and Polluted Environments

Designed with high moisture ingress resistance, our Cast Resin Dry Type Transformers operate reliably in coastal zones, chemical plants, food processing units, and other environments where humidity and airborne pollutants are a concern.

Longer Service Life

Lower thermal and dielectric ageing means your transformer lasts longer — protecting your capital investment and reducing the frequency of costly replacements.

Tirupati Transformers: Leading Dry Type Transformer Manufacturer in India

Tirupati Transformers Pvt. Ltd. has established itself as a trusted name in the Indian transformer industry. Every Dry Type Transformer Manufacturer India we manufacture goes through rigorous quality checks, ensuring it meets the demands of diverse industrial and commercial applications.

Advanced Insulation Technology

We manufacture dry-type transformers using two globally recognized insulation systems:

• Class F Insulation (Fiber-based): Suitable for standard indoor applications, rated up to 155°C.
• Class H Insulation (NOMEX-based): High-performance insulation rated up to 180°C, developed using NOMEX® technology by DuPont, ideal for extreme industrial environments.

Fully Customizable to Your Requirements

Our engineering team works closely with clients to customize each unit based on voltage ratio, KVA rating, winding material (copper or aluminium), tap changer type, enclosure rating, and terminal arrangement.

Key Features of Our Dry Type Transformers

High Efficiency and Energy Saving

Engineered for low no-load and copper losses, our transformers maximize energy efficiency — directly reducing electricity bills and your facility’s carbon footprint.

Wide Range — 100 KVA to 2500 KVA

From compact units for commercial buildings to high-capacity transformers for industrial plants, we cover the full range of 100 KVA to 2500 KVA.

Copper and Aluminium Winding Options

Choose copper winding for superior conductivity and longevity, or aluminium winding as a cost-effective alternative — both delivering excellent performance under rated conditions.

On-Load and Off-Load Tap Changers

Available with both OLTC (On-Load Tap Changer) and off-load tap changers, allowing voltage adjustment without interrupting power supply.

High Short-Circuit Withstand Strength

Built with higher dynamic mechanical strength to protect your electrical system from damaging fault currents.

Applications of Dry Type Transformers

Commercial and Residential Buildings

Safe for installation in basements, electrical rooms, and rooftop substations of shopping malls, office complexes, hospitals, hotels, and residential high-rises where fire safety is paramount.

Industrial Facilities

Ideal for steel plants, cement industries, chemical factories, paper mills, and mining operations where dust, moisture, and corrosive environments demand robust transformer solutions.

Data Centres and IT Parks

Critical power infrastructure for data centres requires zero-tolerance reliability. Dry-type transformers deliver clean, consistent power without the maintenance overhead of oil-filled alternatives.

Renewable Energy — Solar and Wind

Our Solar Inverter Duty Transformers and dry-type units are widely deployed in solar farms and wind energy projects across India.

Railways and Metro Rail

Approved for railway traction substations, metro rail power distribution systems, and underground station electrical infrastructure.

Utilities and Power Distribution

Used by electricity boards and private distribution companies for urban and rural power distribution networks up to 33 KV.

Frequently Asked Questions About Dry Type Transformers

What is the difference between a Dry Type Transformer and an Oil Type Transformer?

A Dry Type Transformer Price India uses solid insulation such as epoxy resin or NOMEX and air for cooling — making it completely oil-free, fire-safe, and environment-friendly. An oil-type transformer uses mineral oil for cooling, which presents fire and environmental risks. Dry-type units are the preferred choice for indoor, sensitive, and high-safety installations.

What is the maximum KVA rating available?

Tirupati Transformers manufactures Cast Resin Transformers Manufacturer from 100 KVA to 2500 KVA with voltage ratings up to 33 KV. Custom ratings can be discussed with our engineering team.

Are these transformers suitable for outdoor installation?

Standard dry-type units are designed for indoor use. Units with IP54 or higher enclosure protection for outdoor or semi-sheltered locations are available on request.

Which insulation class should I choose — Class F or Class H?

Class F (155°C) suits most standard commercial and industrial applications. Class H (180°C, NOMEX) is recommended for high-ambient-temperature environments or heavy-duty cycles.

What is your delivery timeline?

Standard delivery is 4 to 8 weeks depending on KVA rating and customization. Contact our sales team for exact timelines.
