The Bildal Medium Intensity Series Isolation Transformer (SIT) is a high performing toroidal transformer made from high grade, grain-oriented silicon steel.

  • Compared to a traditional transformer, the toroidal – or doughnut-like shape – provides higher efficiency and lower stay losses (leakage flux).
  • Compact in size and lower in weight, making it easier to fit inside pits.
  • Resistant to UV exposure and won’t corrode over time.
  • Suitable for areas contaminated with most oils, aircraft fuels, soil acids and alkalis and de-icing fluids.
  • Can be installed above ground, in concrete, non metallic pits, metal cans or direct buried.
  • Engineered to operate submerged in water indefinitely.
  • Injection moulded TPR rubber for uniform encapsulation to yield a lower leakage current.
