Electric arc furnace transformers (EAF) are essential equipment in most steel factories. Therefore, they require specialized design, engineering, and production technology to ensure proper performance under harsh operating conditions involving mechanical, insulation, and temperature stresses. The unique loading cycle of these transformers subjects them to significant stresses. Special considerations in the design and production of EAF transformers include alternating entry and exit from the circuit, high inrush current, high operating current, operation close to short circuit conditions, fast transient overvoltages, harmonic conditions, and the frequency of the voltage regulator switch operation under load.
Arya Transfo Industrial Group uses the latest technology to design and produce all types of furnace transformers, taking into account these special requirements. Depending on customer needs, the following methods are offered:
– Construction by booster method using one or two cores
– Utilization of various voltage regulation mechanisms, balancing product quality and price
– Using new design methods to increase the life of the key components under load
– Use of bushings on the low voltage side with water-cooled tubes
– Creating an outlet on the cover or the side wall of the transformer

Arya Transfo ensures that their transformers are designed to handle the demanding conditions of electric arc furnace operations, providing reliable and efficient performance.
