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.
Incorrect transformer selection can cause unstable furnace temperature, lower smelting efficiency, frequent transformer failures, shutdown maintenance, and long-term costs far higher than the initial equipment price difference.
The price difference mainly depends on whether the transformer is designed for arc impact, whether the low-voltage winding structure is strong enough, and whether it supports real electric furnace operating conditions.
Yes, electric furnaces are strong fluctuating loads, and ordinary transformers may suffer from excessive temperature rise and accelerated insulation aging without anti-fluctuation design.
Yes, our electric furnace transformers help improve production efficiency by making the arc more stable, increasing heating efficiency, and reducing downtime.
Instead of only selling transformer parameters, we design equipment according to actual electric furnace operating conditions to improve operating stability and reduce overall smelting costs.
