Electrical &amp; Power Generation

Hermetic 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

Electrical Equipment Product

Dry-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.

Project Engineering and Configuration

We size the right regulator or UPS configuration from load power (kW/kVA), supply voltage, phase count and backup time. Outside standard families, our technical team works one-to-one on power distribution panels, site transformers and custom engineering. The power calculator shows approximate capacity; project quotes needing special engineering may take a few days once scope is clear.
