- Project-specific technical requirements
An electric furnace requires a dedicated transformer because it has extreme current fluctuations, frequent impact loads, and long-term high-load operation that ordinary transformers cannot withstand.
Improper transformer selection can lead to unstable furnace temperature, lower melting efficiency, frequent transformer failures, shutdowns, and much higher long-term operating costs.
The price difference mainly depends on whether the transformer is designed for arc impact, low-voltage winding strength, and real electric furnace operating conditions.
Yes, strong current fluctuations and unstable arcs can cause overheating and accelerated insulation aging in ordinary transformers, so electric furnace transformers must be designed to withstand load fluctuations.
Yes, our electric furnace transformers help improve production efficiency by stabilizing the arc, improving heating efficiency, and reducing downtime.
Instead of only selling transformer parameters, we design equipment based on actual electric furnace operating conditions to improve stability and reduce overall smelting costs.
