Finding a dependable transformer manufacturer Noida is no small task — your operations, your uptime, and your compliance depend on it. At Tirupati Transformers Pvt. Ltd., we have spent over a decade building electrical transformer manufacturer Noida that perform reliably under India’s toughest industrial and climatic conditions. From a compact 100 kVA distribution unit for a housing colony to a 10 MVA power transformer manufacturer Noida for a grid substation, every product that leaves our facility is engineered with precision, tested rigorously, and backed by a warranty that means something.
We do not just manufacture and ship. We design, consult, commission, and support — making us more than a supplier, and closer to a long-term electrical infrastructure partner for businesses across Noida, Greater Noida, Delhi NCR, and pan-India.

Capacity: 100 kVA – 10 MVA | Voltage Class: 1.1 kV to 69 kV | Cooling: ONAN / ONAF / OFAF / ONWF / OFWF | Tap Changer: OCTC & OLTC | Standard: IS 2026 / IEC 60076
Tirupati Transformers Pvt. Ltd. was established with a single guiding principle: build transformers the way they should be built — without shortcuts, without compromise. Our manufacturing facility in Noida is equipped with precision winding machines, vacuum drying chambers, and a dedicated electrical testing laboratory that meets BIS (Bureau of Indian Standards) requirements.
As a certified transformer manufacturer Noida, our entire production process conforms to ISO 9001:2015 quality management standards. Our transformers carry BIS approval and are manufactured per IS 2026 / IEC 60076 norms — the same standards that major power utilities and EPC contractors demand.
As a full-range transformer manufacturer Noida, we produce every major transformer type under one roof — eliminating the need to source from multiple vendors and ensuring design consistency across your project.
Our power transformers are engineered for high-voltage transmission networks, industrial substations, and utility-scale power distribution. We use Cold Rolled Grain Oriented (CRGO) silicon steel cores to minimize no-load losses and maximize energy efficiency — particularly important with BEE Star Rating compliance becoming mandatory.
Ideal for: Grid substations, large manufacturing plants, EPC contractors, electricity distribution companies.
Our distribution transformers step down voltage from 11 kV to 433 V for last-mile power delivery. Available in oil-cooled (ONAN/ONAF) and dry-type variants, these units are the workhorse of every housing colony, commercial complex, and light industrial unit.
Ideal for: Residential townships, malls, SMEs, municipal utilities.
When oil is not an option — in basements, metro stations, high-rise buildings, or fire-sensitive zones — our cast resin transformers deliver the same performance without the fire risk. They require minimal maintenance, have a lifespan exceeding 25 years, and can operate in Class F and Class H insulation environments.
Our VPI transformers are ideal for harsh industrial environments where moisture, dust, or chemical exposure is a concern. The vacuum pressure impregnation process ensures deep resin penetration into the windings, providing superior insulation and mechanical strength.
Renewable energy projects require transformer manufacturer Noida purpose-built for harmonic-rich inverter outputs and variable input conditions. Our solar inverter duty transformers are optimized for ground-mounted solar farms, rooftop installations, and hybrid energy systems — supporting India’s push toward the 500 GW renewable energy target under MNRE guidelines.
Steel plants, foundries, and heat treatment units operate under extreme electrical conditions. Our furnace duty transformers are purpose-engineered with heavy-duty copper windings and reinforced insulation to handle continuous high-current, low-voltage operation without degradation.
For variable frequency drives, rectifiers, and motor-starting applications, our converter duty transformers and auto transformers provide compact, cost-efficient voltage adjustment. They are widely used in HVAC systems, chemical process industries, and heavy machinery installations.

There are dozens of transformer suppliers in the NCR region, but very few that combine manufacturing depth, engineering expertise, and service commitment under one roof. Here is what genuinely differentiates us:
Since Tirupati Transformers is a direct transformer manufacturer Noida — not a trader or reseller — you receive factory pricing without distributor margins. For bulk buyers, this translates to significant savings per unit, especially on large project orders.
Our in-house testing lab performs a complete battery of acceptance tests per IS 2026 / IEC 60076 — including turns ratio test, polarity test, insulation resistance (IR) test, induced overvoltage withstand test, no-load and full-load loss measurements, and temperature rise tests for special designs. Full test certificates accompany every unit.
Not every project fits a standard catalogue. Our engineering team designs transformer manufacturer Noida to client-specified parameters — unusual KVA ratings, non-standard vector groups, special IP ratings, high-altitude variants, and seismic-zone-rated designs. If you have a requirement, send it to us and we will quote within 24 hours.
Standard range transformers are dispatched within 7–15 working days. Clients in Noida, Greater Noida, and Delhi NCR often receive same-day or next-day delivery for items available in our dispatch inventory. For outstation projects, we arrange transport and insurance from our end.
Our relationship with clients continues long after delivery. We offer Annual Maintenance Contracts (AMC) that include preventive maintenance visits, transformer oil BDV testing, thermal scanning, and priority breakdown response. We also provide rewinding, reconditioning, and oil filtration services for existing transformer manufacturer Noida.
Every transformer we manufacture comes with a 24-month standard warranty against manufacturing defects. Extended warranty and comprehensive AMC packages are available for clients seeking long-term performance assurance.
As a versatile transformer manufacturer Noida, our products are deployed across a broad spectrum of sectors:
Quality in transformer manufacturing is not an inspection step at the end — it is built into every stage of production. Here is a transparent look at how every unit from Tirupati Transformers is made:
Our engineers begin with your load profile and electrical parameters, designing the transformer manufacturer Noida for optimal efficiency, thermal performance, and long-term reliability — factoring in applicable IS / IEC standards and any project-specific requirements.
Cold Rolled Grain Oriented silicon steel laminations are precision-cut using automated step-lap cutting machines. This minimizes air gaps, reduces audible noise, and ensures low no-load losses — a direct benefit to your energy bills over the transformer’s lifetime.
Primary and secondary windings are wound using high-purity electrolytic copper or aluminium conductors. Each layer receives multiple wraps of kraft paper and pressboard insulation, building up the dielectric strength needed for safe, long-term operation.
The wound assembly is clamped into the laminated core, then placed inside a fabricated mild steel or stainless steel tank. Radiators, conservators, bushings, buchholz relays, and explosion vents are fitted as per the design specification.
The assembled transformer undergoes vacuum oven drying to remove all residual moisture from the insulation system. It is then filled under vacuum with high-grade transformer mineral oil — or biodegradable ester fluid for eco-sensitive applications.
Final acceptance testing per IS 2026 / IEC 60076 covers: turns ratio, polarity, insulation resistance (IR), short circuit impedance, no-load and load loss measurements, and induced overvoltage withstand. Test reports are issued and shared with the customer.
Units are packed in wooden crates or skid-mounted depending on size. For large transformers, nitrogen blanket packing is used during transit to prevent oil oxidation. On-site commissioning support is available on request.
We combine over 12 years of manufacturing experience, ISO 9001:2015 certification, BIS-approved products, an in-house testing laboratory, and direct factory pricing — making us one of the most credible transformer manufacturer Noida for both domestic and industrial buyers.
