Ladle Furnace Transformer (LF Transformer): Design, function and maintenance in secondary steel refining
The ladle furnace transformer is the electrical heart of the secondary metallurgy stage in electric steelmaking. While the EAF transformer captures attention with its raw power figures, the LF transformer is equally critical to the final quality of the steel produced,...
Medium Power Transformers: Design, applications and lifecycle management
Medium power transformers are the workhorses of industrial and utility electrical systems. Rated between approximately 5 MVA and 100 MVA and operating at voltages up to 72.5 kV, they handle the critical step-down function between transmission or sub-transmission...
CEM engineering expands ISO 9001:2015 Certification to cover winding production facility
We are pleased to announce a significant milestone in CEM Engineering's quality journey: our ISO 9001:2015 certification, issued by RINA Services S.p.A. under certificate number 45715/24/S, has been extended to formally include our winding production facility in...
EAF Transformer: Everything you need to know about Electric Arc Furnace Transformers
The EAF transformer is the core of every electric steelmaking plant. Without it, the electric arc cannot exist, the scrap cannot melt, and the entire production process stops. Yet it is one of the most technically demanding pieces of electrical equipment in industrial...
Large Power Transformers: A technical guide to high-voltage industrial and grid applications
Large power transformers are the backbone of modern electrical infrastructure. Without them, the electricity generated at a power plant would never reach the end user, industrial facilities running at high voltage could not connect to the grid and cross-border...
