Introduction
The 1000 kVA transformer, also known as a 1 MVA transformer, plays a crucial role in medium to large-scale power distribution networks. It’s commonly found in industrial plants, commercial complexes, hospitals, and renewable energy projects, ensuring efficient voltage transformation for safe and reliable power use. For those considering such an investment, understanding the 1000 kVA transformer price, types, specifications, and cost-influencing factors is essential.
This article serves as a comprehensive guide for professionals, engineers, and procurement teams looking to acquire a 1000 kVA transformer. It complies with Google SEO optimization best practices, covering primary keywords, semantic relevance, structured content, and user-centric information.
What is a 1000 kVA Transformer
A 1000 kVA transformer is a medium-voltage transformer designed to convert electrical energy from a higher voltage (such as 11kV or 33kV) to a lower usable voltage (such as 400V or 415V). It can support large commercial loads and is often a key component in critical infrastructure.
Depending on the application and environment, a 1000 kVA transformer can be manufactured in several configurations:
- Oil-immersed
- Dry-type
- Pad-mounted
- Amorphous core (for energy efficiency)
1000 kVA Transformer Price Range
The cost of a 1000 kVA transformer depends on various factors such as cooling type, voltage rating, insulation material, core material, and origin.
| Transformer Type | Estimated Price Range (USD) |
|---|---|
| Oil-Immersed | $8,000 – $14,000 |
| Dry-Type | $12,000 – $20,000 |
| Amorphous Core | $14,000 – $24,000 |
| Pad-Mounted (Enclosed) | $13,000 – $22,000 |
These prices are indicative and may vary based on customization, testing requirements, freight, and certification standards.

Factors Affecting the Price of a 1000 kVA Transformer
- Cooling Type
- Oil-immersed transformers are less expensive but require routine maintenance.
- Dry-type transformers are ideal for indoor use and are safer but cost more.
- Core Material
- CRGO Steel Core: Standard, widely used.
- Amorphous Metal Core: More energy-efficient, higher cost.
- Voltage Class and Configuration
- Higher voltages or special winding configurations add to the price.
- Efficiency and Losses
- Low loss transformers (meeting BEE or DOE standards) have a higher upfront cost but save more energy over time.
- Custom Features
- Tap changers (manual or automatic)
- Protective relays and sensors
- Remote monitoring systems
- Weatherproof or explosion-proof enclosures
- Certifications and Standards
- Meeting IEC, ANSI, GOST, or BIS standards often involves more testing and engineering, affecting the final price.
Frequently Asked Questions
Q1: How heavy is a 1000 kVA transformer?
An oil-immersed 1000 kVA transformer typically weighs between 2,000 and 3,500 kg, depending on the design.
Q2: Can a 1000 kVA transformer be used for both indoor and outdoor applications?
Yes, oil-immersed units are usually installed outdoors, while dry-type or pad-mounted versions are preferred for indoor use or confined spaces.
Q3: What is the lead time for manufacturing and delivery?
Standard models may be delivered within 2 to 4 weeks, while customized versions may take 6 to 8 weeks or more.
Buying Tips for a 1000 kVA Transformer
- Request Multiple Quotations: Compare suppliers based on price, specifications, and service.
