SPECIAL TRANSFORMERS

Transformers Designed for Demanding Loads

Yuantong designs special transformers for loads that standard distribution units cannot handle: electric furnace transformers for melting and heating, rectifier transformers for DC supply, dual-winding dry-type transformers for solar PV inverters, and ZGS combined transformers for wind farms. Each unit is designed to the load profile in your specification and routine-tested in our 220 kV test station before it ships.

CONSTRUCTION & CHARACTERISTICS

How We Engineer Special Transformers

Load-Based Design

Each transformer is calculated for your load profile, not taken from a standard catalogue.

Harmonic Duty

Windings and cooling sized for the harmonic currents of rectifier and furnace loads.

Split and Dual Windings

Multiple LV windings for inverters and converters.

Wide Voltage Regulation

Tap ranges designed for furnace and process control.

Dry or Oil Insulation

The insulation system is chosen to suit the site and duty.

Full Testing

Routine tests in our 220 kV test station, with type test reports on request.

QUALITY & TESTING

Tested Before It Leaves the Factory

Routine Tests

Every unit is tested in our 220 kV test station before release.

Type-Tested

Type tests passed at China's national testing centres.

ISO Certified

ISO 9001, ISO 14001 and ISO 45001 management systems.

Grid Qualified

Qualified supplier to State Grid and China Southern Power Grid.

FAQ

Special Transformer FAQ

What information do you need to design a special transformer?

Send us the load type, rated power, primary and secondary voltages, harmonic content or duty cycle, cooling method and site conditions. A load profile or single-line diagram helps us design faster.

Yes. We supply dual-winding dry-type transformers for solar inverter stations. Tell us the inverter rating and grid voltage for a quotation.

Yes. We design rectifier and electric furnace transformers to the load and regulation range in your specification.

The minimum order is one unit. Lead time depends on the design; we confirm it in our quotation.

We design to IEC or GB standards, or to the standard named in your specification. A routine test report is supplied with every unit.
