Structural Features

  • The iron core is made of high-quality cold-rolled oriented silicon steel sheet, the surface is specially treated with protective resin, and full-inclined seam lamination structure is adopted.
  • The low-voltage coil is of foil winding structuremade of high-quality steel foil. The high-voltage coil is of layer structure formed by vacuum epoxy casting technique. Lowpartial discharge in similar product catalog;
  • This model features high mechanical strength, strong short-circuit resistance, good dust-proof and anti-fouling performance. Its service life is longer than other dry transformer.
  • The product’s beautiful stainless steel shell is durable and can provide better protection for the electrified parts of the transformer. Itworks well outdoors.
  • With excellent moisture-proof and corrosion-resistant performance, the product is safe, fire-proof and pollution-free.It’s especially suitable for working in extremely harsh environmental conditions, and can restart without drytreatment after shutdown.
  • Good heat dissipation performance and strong overload capacity enables it operate with higher capacitywhen forced air cooling.
