Product Description

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, with reduced temperature rise
Environmentally friendly design reduces long-term operational costs
Improves system stability and grid efficiency
S20 type energy-efficient secondary oil-immersed transformer
