GAUTENG-FABRICATED
High-Voltage Transformer Cores
Precision-cut, grain-oriented silicon steel cores engineered to minimize magnetic hysteresis and guarantee SANS-compliant grid performance under continuous peak load.
Magnetic Performance
We utilize high-permeability, grain-oriented silicon steel sheets cut at precise angles to align with the rolling direction. This meticulous orientation reduces magnetic resistance and limits no-load losses within municipal distribution networks.
Engineering Tolerances
The step-lap stacking configuration optimizes the flux transition across joints. By shifting the lamination seams incrementally, we eliminate localized saturation, lower operational noise levels, and improve overall thermal dissipation efficiency.
Lamination thickness down to 0.23mm. Rigid clamping structures prevent physical deformation under high-voltage mechanical stress, maintaining tight dimensional alignment across the entire core assembly.
The Step-Lap Process
Precision Shearing
Silicon steel is slit and cut on high-speed CNC lines to achieve exact step-lap geometries, ensuring burr heights remain strictly under industry limits to prevent interlaminar short circuits.
Rigid Clamping
Heavy-duty steel channel clamping bands are tensioned around the stacked column limbs, minimizing mechanical vibration and eliminating the hum associated with magnetostriction.
