HENTG Power 50kVA Double Winding Oil Immersed Transformer Variable Voltage Step Down Power Transformer
Oil‑immersed transformers with optimized cooling channels using pressboard gaskets—supporting both ONAN and ONAF cooling for efficient heat management.

Built with high-quality cold-rolled silicon steel sheets and oxygen-free copper windings, minimizing no-load and load losses.

Lower core and copper losses than IEC standards, reduced temperature rise, and environmentally friendly.

Reduces long-term operational costs while improving system stability and grid efficiency.
