New grade of GOES improves transformer efficiency New grade of GOES improves transformer efficiency - news feed from the Electrical News Portal

Leading steel producer ArcelorMittal has developed a new intermediate class of grain oriented electrical steels (GOES), helping transformer manufacturers to meet environmental targets.
CWIEME Berlin, the world’s largest electrical engineering exhibition, will see the launch of a new grade of electrical steels from ArcelorMittal. These improved conventional grain oriented steels will sit between the existing conventional and high permeability classes, helping manufacturers of transformers and transformer cores to achieve the right performance-cost balance.

The intermediate option was made possible thanks to a series of optimizations to the production process, aided by considerable investments at the company’s site in the Czech Republic. The Frýdek-Místek facility now includes a state-of-the-art decarburizing annealing line and a new thermo-flattening line complete with an improved inspection system, as well as revamped and upgraded cold rolling mills.
Improved life cycle cost
“We’ve noticed a shift in purchasing decisions over the past few years – from a focus on initial outlay to overall lifetime cost,” says Sigrid Jacobs, portfolio director for electrical steels at ArcelorMittal Global R&D .“Customers want to have the best performance in terms of energy consumption, emissions and service life – especially for transformers that run continuously. Our improved conventional GOES offer an excellent solution.”

Mrs. Jacobs will support the launch of the new GOES with a seminar at CWIEME Central on Tuesday 24th June, 10:55-11:35. Her presentation, entitled ‘Performance improvement for transformer core design with key developments in grain oriented electrical steel’, will discuss the optimal material choice for different transformers.

CWIEME visitors can also find out about ArcelorMittal’s new offering at the company’s booth 41A11 in hall 4.1. Visitors are encouraged to bring along their technical data for suitability tests and feel free to ask questions.
“We would like our customers to think of us not just as a supplier but as co-engineers,” says Mrs. Jacobs. “We have more than 1,300 R&D staff around the globe working with customers to help improve the overall quality and efficiency of their products every day.”

ArcelorMittal’s experts will also be on hand to discuss fully-processed and semi-processed non-oriented steels (NOES), cores for magnetic circuits and iCARe™ – a range of electrical steels specifically designed to assist the automotive industry in its bid to become more environmentally-friendly.
