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。.

Main Types of Three Phase Distribution Transformers

We manufacture three three-phase types:

Oil-immersed

Standard outdoor units for grid and industry.

Dry-type

SCB cast resin units for indoor duty.

Amorphous core

SCBH units for ultra-low no-load loss.

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.

よくある質問

Three Phase Distribution Transformer FAQ

Common questions about three phase distribution transformers and factory sourcing.

三相配電トランスとは何ですか?
A transformer that steps a three-phase distribution voltage down to utilisation level for networks, industry and commercial buildings.
どのような容量が利用可能ですか?
From 30 kVA to 63000 kVA in three-phase configurations.
What technologies do you offer?
Oil-immersed, dry-type SCB and amorphous core SCBH units.
What vector groups are available?
Yyn0, Dyn11 and YNd11 depending on your network and earthing.
What is a vector group?
A vector group describes the winding connection and phase shift between the HV and LV sides – for example Dyn11 or Yyn0. It determines how the transformer connects into the network and handles neutral earthing.
What are your delivery terms?
FOB / CIF / DDP terms are available, with lead times confirmed against your project schedule.
