Traditional Furnace Transformer for LF and LF application and new energy efficient EAF feed through HI-performance power unit
In the modern steel production industry, Furnace Transformers play a critical role in ensuring efficiency, safety, and top-level performance in industrial plants. In particular, Electric Arc Furnace (EAF) transformers and Ladle Furnace (LF) transformers are designed to meet the increasingly demanding needs of electric steelmaking.
Specialtrasfo specializes in the design and manufacturing of Furnace Transformers for EAF and LF applications, meeting the highest quality standards required by the steel industry.

Sectors in which the Furnace is applied
Our Expertise
Thanks to extensive experience in challenging industries such as metallurgy and Oil & Gas, our Furnace Transformers stand out for:
Power ratings up to 200 MVA
Secondary current up to 100 kA
Primary voltage AC up to 145 kV
Maximum weight over 200 tons
Flexible configurations:
One-core solution for compact design
Booster solutions for advanced voltage control
Available in single-phase or three-phase versions
Integrated voltage regulation with On Load Tap Changer (OLTC):
Available in American or European design, depending on customer requirements
Fully customizable connections:
Closed delta or open phase configurations
Copper busbars or water-cooled tubes for efficient high-current management
EAF transformers must withstand extreme working cycles and highly discontinuous loads, typical of scrap melting in steel plants. Specialtrasfo designs Electric Arc Furnace Transformers capable of:
• Withstanding high current peaks
• Ensuring maximum reliability during critical start-up and melting phases
• Optimized solutions to reduce energy losses and increase the overall efficiency of the plant
During the secondary refining process, the Ladle Furnace Transformer provides energy to keep the molten metal at the right temperature and supports metallurgical reactions. Our LF transformers are engineered to:
• Provide adjustable voltage for precise process control
• Feature robust designs to withstand prolonged operating cycles
• Be fully compatible with the latest electric steelmaking technologies
We proudly collaborate with some of the world’s leading steel industry manufacturers and technology providers,(player principali del settore SMS Group, Primetals, Danieli, and Tamini), supplying high-quality, fully customized furnace transformers tailored to each specific requirement.
Series reactors are installed on the electrical furnace EAFs to improve arc stability, power factor and EAF efficiency. Available with:
- ONAN, ONAF, OFWF cooling system
- OLTC, DETC tap changer.
