Hermetic Distribution Transformers
Distribution TransformerHermetic distribution transformers are sealed from atmosphere so air and moisture cannot enter, protecting insulation and extending life. Oil expansion is handled by corrugated tank walls. The plant builds oil-immersed hermetic units up to 2500 kVA and 36 kV with ONAN/ONAF/OFAF cooling and Yzn/Dyn or Dyn/YNyn vector groups 5 or 11.

Dry-Type Transformers
General TransformersDry-type transformers have magnetic circuit and windings not immersed in insulating liquid; they contain no oil. Windings are encapsulated in glass-fibre-reinforced epoxy resin and operate in air or gas. Versus oil-filled units they need less space, little maintenance, resist ambient humidity and avoid oil pollution. Eren Trafo builds dry-type units up to 5000 kVA and 36 kV with AN/AF cooling.
