Product details

Built for indoor distribution in commercial, industrial and infrastructure settings, this epoxy-resin cast dry-type transformer steps 6.3kV down to 400V while keeping its environmental footprint light. Rated at 2500kVA, the HV windings are cast in resin and can be specified in copper or aluminium, giving oil-free, low-maintenance operation at either 50Hz or 60Hz.

Design & Construction

  • HV winding columns are resin-cast and sit on a rollered steel base frame
  • Top-mounted HV terminals come with bushings and tap links
  • LV side connects through copper busbars
  • Open-type dry build removes oil entirely, lowering fire risk
  • A compact footprint suits indoor placement

Applications

A good match for indoor switchrooms, power plants, commercial buildings, hospitals and industrial sites that call for oil-free, fire-safe transformers.

Customisation Options

Capacity, voltage ratio, vector group, protective enclosure (IP-rated housing) and temperature controller can all be adapted to the project at hand, with copper or aluminium windings available on request.

Ordering Information

When ordering, please confirm the rated capacity, primary/secondary voltage, frequency, vector group and the standard that applies.
