Single Phase Dry Type Transformers We Manufacture

Single phase dry type transformers from 1 kVA to 100 kVA – step-down, isolation and control transformers for commercial and industrial applications.

What Is a Single Phase Dry Type Transformer?

A single phase dry type transformer converts a single-phase voltage level – for example 230 V to 110 V, or 380 V to 220 V – using air or resin insulation. It is the workhorse of control circuits, lighting and small power applications.

Every plant and building uses single-phase transformers for control power, instrument supply, lighting and HVAC. A reliable unit keeps these systems running with minimal attention.

  • 1 kVA – 100 kVA – capacity range for control, lighting and small power.
  • Dry-type construction – no oil – safe for panels and occupied areas.
  • Custom ratios – 230/110 V, 380/220 V and other combinations.
  • 50,000m² factory – in-house winding, drying, assembly and testing.
  • 350+ employees – engineering and export teams per order.
  • OEM / ODM & wholesale – custom branding, packaging and volume pricing.

Main Types of Single Phase Dry Type Transformers

We manufacture three single-phase types:

Control transformer

Low capacity units for control circuits and relays.

Isolation transformer

1:1 isolation for sensitive and measurement equipment.

Step-down distribution

Voltage conversion for lighting, HVAC and small loads.

Open Wound vs Encapsulated Single Phase Transformers

Open-wound units are economical and suit clean, dry panels. Encapsulated units protect against dust, moisture and vibration in harsher environments.

We build both and recommend the construction based on your installation environment.
