High-capacity machinery designed to streamline coil preparation, core cutting, and steel processing.
Clarifying technical inquiries, performance metrics, and procurement standards
Compared to standard planar stacked designs, a 3D triangular rolled core layout provides a more symmetrical three-phase magnetic path. This symmetry minimizes magnetic reluctance, cuts no-load current requirements, and reduces core noise. For grid operators, this results in lower operating losses and reduced hum in municipal installations.
We achieve this through two main design improvements: optimized internal cooling channels within the winding structure and high-precision automatic corrugated welding. The corrugated sheets increase external surface area to improve convective oil cooling. Together with high-conductivity insulation materials, these features prevent hot spots and help maintain stable operating temperatures.
Slitting and winding processes introduce mechanical stress into grain-oriented silicon steel, which degrades its magnetic properties. Heating the material in a vacuum annealing furnace relieves these mechanical stresses without causing oxidation. This process restores the grain orientation, helping to minimize hysteresis losses in the completed transformer.
We offer extensive customization for primary and secondary voltages, winding configurations, and physical dimensions. Additionally, we provide custom integration for cooling types (ONAN/ONAF) and specify localized auxiliary equipment such as off-circuit tap changers, pressure relief devices, and digital temperature indicators.
All our designs undergo routine testing, including winding resistance, voltage ratio, impedance voltage, and insulation resistance checks, before leaving the factory. For project certifications, we facilitate full type-testing compliance, including temperature rise and impulse testing, through accredited laboratories.
