EAF  TRANSFORMER

EAF transformers

EAF transformers (electric arc furnaces) are transformers specialized in the steel industry that supply high-voltage electrical energy to electric arc furnaces.

These Transformers are the key equipment in a steel plant. Such transformers are designed to be durable, able to withstand the severe environment and to be safe through the melting process.

EAF transformers mostly operate at a higher voltage of, 30-150 kV, and a current of up to 100000 A. These are vast solutions with tough insulation and cooling systems that can handle the high temperatures and electromagnetic forces that are generated during the process.


EAF transformers require specialized manufacturing and testing processes to operate reliably and reduce the downtime in steel production facilities due to their different design and operating conditions.

Manufacturers of EAF transformers must possess a deep understanding of the unique challenges and requirements of the steel industry to design and build these transformers to the exacting standards needed. This includes expertise in areas such as thermal management, fault protection, and precise voltage regulation to accommodate the extreme operating conditions of the EAF.

Top-tier EAF transformer manufacturers, like CEM, will also offer a range of value-added services to their steel producer customers, such as on-site installation, commissioning, and ongoing maintenance and repair  support to maximize the lifespan and performance of these critical assets.

By partnering with an experienced EAF transformer specialist, steel companies can ensure the reliable, efficient, and cost-effective operation of their electric arc furnaces, a key factor in maintaining a competitive edge in the global steel market.
