Price, availability and lead time on request. We help with analogue selection, customs clearance and delivery.
Description
Step voltage is up to 500 V, step capacity up to 85 kVA and the number of positions up to 9. The insulation is air, so the tap changer works without oil, like the dry-type transformer itself. The automatic voltage regulator is built into the unit and a separate control cabinet is not required. The AVT is fitted to cast-resin dry-type transformers where voltage must be regulated without oil-filled equipment.
