Electric Arc Furnace Transformers
Electric Arc Furnace Transformers
At kVA Process Transformers Pvt. Ltd., we design and manufacture Electric Arc Furnace (EAF) Transformers for a wide range of furnace applications. These transformers are a critical component in the steelmaking process, providing reliable power for smelting scrap iron and refining steel. Beyond steel, they are also used in glass, ceramics, ferroalloys, abrasive materials, semiconductors, and advanced metallurgical processes. Our EAF Transformers are available in both AC and DC furnace configurations, with power ratings ranging from 500 kVA to 24 MVA, and are engineered for robust performance under extreme electrical, thermal, and mechanical stresses.
Key Features
- Robust Construction: Built to handle heavy-duty furnace operations, ensuring mechanical strength, thermal stability, and long service life under continuous high-load conditions.
- Versatile Configurations: Available with On-Load Tap Changer (in-tank or external) or Motorised Off-Circuit Tap Changer for flexible voltage regulation.
- Efficient Secondary & Primary Design:
- Secondary: Open Delta configuration.
- Primary: Y/D (Star/Delta) configuration, customizable as per voltage requirements.
- Series Reactor Options: Available with inbuilt (same tank) or external (separate unit) series reactors for precise arc control.
- Cooling Options: ONAN (Oil Natural Air Natural) or OFWF (Oil Forced Water Forced), depending on size and operational requirements.
Technical Specifications
- Power Ratings: 500 kVA to 24 MVA
- Tap Changer: OLTC (in-tank or external) / Motorised Off-Circuit Tap Changer
- Connections: Secondary Open Delta, Primary Y/D (Star/Delta)
- Series Reactor: Iron-cored, available as inbuilt or external, with parallel tapping connection
