Oil-Immersed Transformers

Amorphous-Alloy 3D Wound-Core Oil Transformer

Ultra-efficient oil transformer pairing amorphous-alloy cores with 3-D wound-core technology — no-load losses cut to a fraction of silicon-steel units (e.g. 100 kVA at just 60–75 W), 30–2500 kVA.

Factory-direct supply Worldwide delivery & export documentation 12-month warranty · extended options
  • Core built from amorphous alloy with 3-D wound-core technology
  • No-load and load losses sharply reduced; major electricity savings in operation
  • Stable and reliable — the 3-D wound core raises short-circuit withstand and overall stability
