Three Phase Distribution Transformers We Manufacture
Three phase distribution transformers from 30 kVA to 63000 kVA – oil-immersed, dry-type and amorphous core – for grid, industrial and commercial duty.
What Is a Three Phase Distribution Transformer?
A three phase distribution transformer steps a three-phase distribution voltage down to utilisation level, feeding balanced power to networks, industry and commercial buildings.
Three-phase units are the workhorse of power distribution – reliable, efficient and available in a wide range of voltage and capacity combinations.
- 30 kVA – 63000 kVA – complete three-phase capacity range.
- Oil, dry & amorphous – three technologies from one factory.
- Standard vector groups – Yyn0 / Dyn11 / YNd11.
- 50,000m²工場 – in-house winding, vacuum drying and testing.
- 350人以上の従業員 – エンジニアリング、品質、輸出チーム。.
- OEM / ODM & 卸売 – カスタムブランディング、パッケージング、ボリューム供給。.

Three Phase vs Single Phase Distribution
Three-phase units supply balanced power to networks and industry at lower cost per kVA; single-phase units serve rural and single-phase networks.
We manufacture both – the choice follows your network and load.
