Open Delta Transformer Cubicle


An open Delta Transformer is a conventional three phase transformer manufactured to give a single phase output. The specialist windings used produce a single phase output (which is not in phase with any of the inputs, isolated from all phases (and until tied down earth), any voltage).

Key Highlights:


  • Lower loss and greater efficiency
  • Customized Compact Designs
  • Cost effective prices
  • Excellent mechanical and short-circuit strength due to the VPI Process
  • Moisture Ingress Resistant & Immune to polluted atmosphere
  • High grade iron core and winding can be wire or foil.
  • Isolated Local Ground Bonded Neutral
  • There is no relative shift in output, so can be used for unbalanced loads and where harmonics are involved.

These types of transformers are also available without cubicle.
