Furnace Transformer
Heavy-duty, high-current transformers for arc furnaces, ladle furnaces, and industrial smelting.
Power That Melts Steel
Hartwerk Power furnace transformers are built for the most punishing electrical environments in industry — electric arc furnaces (EAF), ladle refining furnaces (LRF), and submerged arc furnaces (SAF) for ferroalloy, silicon metal, and calcium carbide production.
Designed to withstand frequent short circuits, severe voltage fluctuations, and extreme thermal cycling. Every unit features reinforced winding clamping, heavy-duty on-load tap changers with wide regulation ranges, and rugged bushing arrangements for high-current secondary connections.
Key Features
Short-Circuit Tolerant
Reinforced winding clamping withstands repeated secondary short circuits during arcing.
Wide Regulation Range
On-load tap changer with up to 30 taps for precise furnace power control.
Extreme Thermal Cycling
Designed for rapid load swings from 0 to 200% in arc furnace melting cycles.
Rugged Construction
Heavy-gauge tank, reinforced core clamping, and high-creepage bushings for harsh conditions.
