A Brief History of The Electrical Transformer Core Once upon a time in a land far, far away… no wait. After a devastating assault on Autobot City, a planet-devouring Transformer set out
Nations around the world are racing to introduce new legislation regulating energy performance for electrical transformers, the effects of which can be felt throughout many industries. Manufacturing companies supplying transformer cores, electrical steel, and
Now more than ever, in a market with multiple options, businesses need to fully capture the customer expectations and provide them with value-added support. In addition to having an outstanding core forming operation including
Feeling like the heat index is somewhere between “oven” and “volcano” lately? You’re not alone. According to NASA, May 2016 was reported to be the hottest May ever recorded, “The latest in a thirteen-month-long
At Corefficient we are always innovating. Either in our products or the processes that we carry out every day. Every one of our employees plays an important role in ensuring we deliver quality products. So
“Transformer energy performance standards being introduced all around the world are spurring transformer manufacturers, as well as their electrical steel, cable and coil winding equipment suppliers, to rethink materials, designs and manufacturing methods in
One of the key decisions in any manufacturing operation is weather to invest in assets, know-how and working capital to make in-house, or purchase from a dedicated reputable supplier… A decision that in our
The magnetic permeability properties of electrical steels are especially sensitive to mechanical stress. During the manufacturing processes required to form a core, steel is subjected to stresses, grain structure is damaged, and the core
The magnetic flux distribution in the transformer core, and particularly at the joints, has a considerable influence on efficiency losses. This is the reason why Step Lap Full Miter (SLFM) stack core designs superseded designs
There is a new challenge for the Transformer Industry in 2016: The US Department of Energy (DOE) has determined that higher transformer energy efficiency standards will result in significant conservation of energy. With new
