What to Consider When Ordering a Single Phase To 3 Phase Transformer
Ordering a phase conversion transformer is a specification exercise: input voltage, output voltage, capacity, starting method, duty cycle and installation environment. Each parameter changes the winding design, so the supplier must engineer, not just sell.
Subian confirms every parameter on drawings before production – input and output voltage, kVA, connection, enclosure and protection – so project buyers know exactly what they are getting.
- Project-based design – every unit engineered to your specification, not from a shelf.
- 5 kVA – 500 kVA – capacity range for irrigation, workshops and small industry.
- Factory-direct pricing – competitive quotes with confirmed lead times.
- 50,000m² factory – in-house winding, drying, assembly and testing.
- 350+ employees – engineering, quality and export teams per project.
- OEM / ODM & wholesale – custom branding, packaging and documentation.
Main Types of Single Phase To Three Phase Transformers
We build three types for project supply:
Oil-immersed conversion
Outdoor-rated units for farms and remote installations.
Dry-type conversion
Indoor, fire-safe units for workshops and commercial buildings.
Panel-integrated package
Transformer and control in one enclosure for plug-and-play projects.

Project-Specific Engineering vs Off-the-Shelf Converters
Off-the-shelf converters are built for generic loads and often fail on real-world starting currents. Project-specific engineering matches the winding and capacitor design to your actual motors, starting method and duty cycle.
For projects that must start on schedule and run for years, the engineered transformer delivers lower lifetime cost and fewer site visits – the value of working with a manufacturer that builds to order.


Selecting a Project Partner for Single Phase To Three Phase Transformers
Evaluate manufacturers on engineering depth, drawing turnaround and test capability. A factory that produces drawings, type tests and delivery schedules in one place simplifies project procurement.
Subian Electric combines a 50,000m² factory, 350+ employees, ISO9001, CE and UL certification and 50+ export markets – a single accountable partner for project supply.
Send your project specification – we will respond with drawings, price and a delivery plan for approval.
Certifications & Quality Assurance
Our phase conversion transformers are produced under ISO9001, ISO14001 and ISO45001 management systems, with CE and UL certification and type test reports.
