The price of a 630 kVA transformer can vary significantly depending on the type, specification, location and market conditions. The following is the general price range for transformers (in US dollars). If you need it, please contact our company.
1. Voltage Class
LV (Low Voltage, e.g., 400V-480V): Lower cost.
MV (Medium Voltage, e.g., 11kV-33kV): 20-50% higher due to insulation/complexity.
2. Efficiency Class
Standard (IE2) vs. High-Efficiency (IE3/IE4): Premiums of 10-30% for higher efficiency.
3. Region
India/Asia: ₹6–15 lakhs ($7,000–18,000) for dry-type.
Europe/US: 20–50% higher than Asian prices.
Africa/Middle East: Import duties can add 15–30%.
4. Additional Costs
Installation, foundations, switchgear, and protection devices (e.g., relays) may add 30–100% to the transformer cost.
Delivery lead times: 8–20 weeks for custom units.
| Type | Price Range (USD) | Key Factors |
| Dry-Type | $10,000 – $25,000 | Indoor use, lower fire risk, limited overload capacity |
| Oil-Cooled (Liquid-Filled) | $15,000 – $40,000+ | Outdoor/utility use, higher overload capacity, longer lifespan |
| Specialty/High-Efficiency | $25,000 – $50,000+ | Low-loss (e.g., EI/TI class), explosion-proof, harmonic mitigation, custom specs |
- Get Multiple Quotes: Contact manufacturers like ABB, Siemens, Schneider, Eaton, or local suppliers.
- Specify Requirements: Provide voltage ratings, winding type (delta/wye), ambient temperature, and certifications (e.g., IEC, ANSI).
- Consider Total Cost: Higher upfront efficiency investments often pay back via energy savings in 2–5 years.
