The transformer CRGO core is the most critical magnetic circuit component in all types of power transformers. Grain-oriented silicon steel has aligned grain structures. Its magnetic performance along the rolling direction is far superior to other directions. This makes it ideal as a magnetic material for transformers. We strictly control every step when we produce these cores. The process starts with incoming material inspection. We check the thickness, grade, and coating integrity of each silicon steel coil. Only qualified genuine materials enter our production line. Our transformer CRGO core is built on a foundation of quality.
We have maintained a stable relationship with Baowu and Ansteel for many years. All our silicon steel coils are genuine products. We never mix in scrap materials. We never reduce the thickness. This is our most basic promise to you. The manufacturing of CRGO cores is very sensitive to the material's orientation direction. If we used substandard steel or steel with insufficient grain orientation, the no-load loss of your transformer would exceed the limit. This is why we never compromise on material quality. Our transformer CRGO core starts with the best raw materials.
Precision Shearing Along the Rolling Direction
We have 15 shearing lines. All of them use CNC systems for automatic cutting. For grain-oriented silicon steel, the cutting direction must align with the rolling direction. This allows us to make full use of the material's magnetic properties. Our technicians check the cutting angle each time we change the coil. This ensures the cut direction is always accurate. During lamination, we stack the sheets according to the lamination factor and joint pattern specified in your drawings. We check the position and direction of each layer. This ensures smooth flux transition between the limbs and yokes. Our transformer CRGO core is made with precision.
100% Inspection Before Shipping
Every CRGO core undergoes a 100% full inspection before shipment. Our quality inspectors use professional tools to measure the geometric dimensions. They check the limb spacing, window size, and overall height. They also inspect the appearance for burrs or turned edges on the silicon steel sheets. Only cores that pass all tests enter the packaging stage. We use rust-proof paper and plastic film for double-layer protection. The outer layer uses reinforced wooden crates. This ensures the product remains undamaged during transit. Our transformer CRGO core is delivered in perfect condition.
