S11 Off-load Distribution Transformers

  Brief  introduction

  • Derived from S9 series, S11 Series are newly developed and designed product with more suitable core structure and higher performance, it is designed with traditional oil cooling components and  protection devices.

  • Compared with the S9 series, S11 series are more energy-saving, environmental-friendly, as no-load loss reduced by 20% than the S9 Series. Because of its high performance in energy saving, the product is recommended by China Machinery Industry Federation (CMIF).

  • The products can be used in various fields, possible applications includes: industrial and petrochemical plants, railways, coal mines and other industries, public places, indoor or outdoor unit substation, it can be especially used as rural and urban power grid distribution equipment.

 Features

  • Oil protection module as Conservator, Dehumidifier etc. Tubular or plate radiator on request.
  • Cold-rolled grain-oriented high-silicone-content steel, step-up lamination, low no-load loss, and low no-load current.
  • First Grade oxygen-free copper, new windings structure.
  • Newly designed insulation structure, high mechanical withstand capability.
  • Cost-effective: 30% reduction on energy costs compared to conventional type.
