Product Description

The S11-M full-sealed oil-immersed power transformer offers low loss, low noise, and high efficiency, achieving significant energy-saving effects while reducing pollution. Unlike common transformers, the full-sealed design eliminates the need for an oil conservator. Volume changes are automatically adjusted via the corrugated tank's elasticity.

Key Features:
  • Stacked imported high-quality cold-rolled silicon steel sheets for reduced no-load loss.
  • Windings made with oxygen-free copper for superior conductivity.
  • Dyn11 connection to minimize harmonic wave influence on power grids.
  • Full-sealed structure prolongs operational life and eliminates maintenance.
