S22-M Series

S22-M Ultra-Low Loss Oil-Immersed Transformer

Why choose ZY POWER for this project

Lower-loss design for long service life

S22-M is positioned for projects where electricity loss, long operating hours and owner life-cycle cost matter more than the lowest upfront price.

Utility and EPC tender compatibility

Voltage ratio, vector group, impedance, tapping range, accessories and documentation can be prepared for project submittals and tender reviews.

Outdoor distribution reliability

The oil-immersed structure supports outdoor operation, natural cooling and robust insulation for distribution substations and industrial feeders.

Configurable shipment package

Packing dimensions, oil shipment method, accessories and loading photos can be coordinated before export delivery.

S22-M series oil-immersed transformer for utility distribution, industrial power systems, rural electrification, and outdoor substation applications. Detailed project ratings and engineering parameters are configured after project review.

Request evidence package

S22-M oil immersed transformer is a high-efficiency distribution transformer for utilities, industrial plants, renewable-energy projects and long-life power infrastructure. It is usually selected when the buyer wants lower operating losses than older distribution transformer series and needs a stronger life-cycle-cost argument for a new installation. For procurement, compare guaranteed no-load loss, load loss, impedance, temperature rise, accessories, test scope and delivery package instead of looking only at the purchase price.

What Buyers Should Confirm

  • Guaranteed no-load loss, load loss, impedance and temperature rise.
  • Required loss table from the project tender or local utility.
  • Outdoor accessories, tank protection, terminal arrangement and oil handling requirement.
  • Routine test report, outline drawing, packing list and export document language.
