Selection notes

How to read this family

Large power transformers sit between generation and the transmission grid, or between a high-voltage grid and a large industrial load. They are engineered around the system study, not selected from a catalogue.

Fengguang builds 110 kV and 220 kV oil-immersed power transformers from 6.3 to 120 MVA. Typical duties include generator step-up, substation step-down, grid interconnection and renewable-energy collection. The design covers the core, windings, tap changer, cooling, bushings, monitoring and test plan as one system.

Every project starts with the single-line diagram, fault level, load profile, grid code and site conditions. Impedance, cooling, tap range, insulation level and transport limits are agreed before design. Routine, type and special tests are documented to IEC 60076, and a witness test can be arranged.

Buyer questions

Questions to settle before the datasheet

What capacity range do you build?
The large power range covers 6.3 to 120 MVA at 110 kV and 220 kV. Higher ratings and other voltage classes can be reviewed as a project-specific design.
Can you supply generator step-up transformers?
Yes. Generator step-up units are designed around the generator rating, fault level, grid code and step-up ratio. The interface with the generator circuit breaker and the unit auxiliary transformer is part of the review.
What cooling types are available?
ONAN, ONAF and OFAF are available. The cooling choice depends on the ambient temperature, load profile, noise limit and the allowed footprint.
How are large transformers shipped?
Transport limits are agreed early. The tank, bushings and cooling equipment may be shipped separately, and the site assembly and oil-filling procedure is included in the documentation.
