No oil checks, pits, or separate rooms required. Lower total cost than oil-immersed units.
3. Energy Efficiency – GB 20052-2024 Grade 1
~30% lower no-load losses vs. SCB12. Operating noise: 45-52 dB(A).
4. Short-Circuit Withstand
Vacuum casting and full-oblique core joints provide up to 8% impedance withstand.
5. Partial Discharge < 5 pC
Vacuum casting eliminates voids, achieving <5 pC PD for decades of reliable insulation.
6. Compact & Environmentally Friendly
30-50% smaller footprint. No contamination risk. Installable at load centers. Fully recyclable.
Production Process
Raw material inspection → HV & LV coil winding → coil curing → core cutting & stacking → coil and insulation assembly →

overall assembly & auxiliary fitting → factory tests → sandblasting and painting → final inspection, marking & packaging.
