S9 Off-load Distribution Transformers

  Brief  introduction

  • S9 Series are designed with traditional oil cooling components and protection device, new design is done at insulation material level to improve the impulse withstand capability. New process, new material and state-of-the-art equipments are also utilized.

  • 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 to absorb oil expansion.
  • 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.
  • New frame and fastener components applied.
