Transformers engineered for export projects
Distribution and power transformers built for the site, not just the nameplate.
Oil-immersed, dry-type and prefabricated substation transformers from 50 to 10,000 kVA. Designed to GB 1094.1 and IEC 60076, routine-tested before shipment, and documented for buyers, EPC contractors and utilities.
Selection brief
What the team needs to review a design basis
- 1Load and duty: maximum demand, overload, load profile and required impedance.
- 2System: voltage class, frequency, fault level, earthing and parallel operation.
- 3Site: ambient temperature, altitude, dust, humidity, salt spray and enclosure.
- 4Documents: standards, type tests, third-party inspection and shipping constraints.

Transformer range
Product families
Six families. One coordinated distribution package.
Start from the application or from the voltage class. Each family links to the models, typical specifications and the questions buyers ask before a datasheet is approved.
Oil-Immersed Transformer
10 kV, 20 kV and 35 kV distribution and power transformers from 50 to 10,000 kVA.
Dry-Type Power Transformer
Fire-safe cast-resin transformers for buildings, data centres and industry.
Large Power Transformer
110 kV and 220 kV transformers for generation, transmission and large industry.
Transformer Station
YB and ZGS compact substations that integrate MV, transformer and LV in one footprint.
Switch Cabinet
GGD, MNS, GCS and SF6 ring-main units for complete power distribution.
Energy Storage Cabinet
Liquid-cooled battery cabinets with PCS, BMS and fire protection in one enclosure.
Engineering discipline
The design review happens before the steel is cut.
Most transformer problems start with a mismatch: an impedance that does not coordinate with the protection, a cooling margin that assumes a 35 °C site, or a terminal arrangement that does not fit the cable box. Fengguang reviews those inputs before releasing the drawing.
One approved datasheet
Ratings, losses, impedance, tap range, cooling and finish are fixed before production.
Tests matched to the unit
Routine test values are recorded against the approved drawing, not a generic catalogue page.
Export-ready documentation
English drawings, material certificates, test reports, O&M manual and packing list.
Harsh-site options
C4/C5 corrosion, IP54 enclosures, high-temperature cooling, 60 Hz and high-altitude correction.
15,000m²
Plant with silicon-steel cutting, winding, vacuum casting, tank fabrication, oil filling and routine test.
Inside the plantSelected models
A cross-section of the range.
Popular distribution, dry-type, large-power and substation configurations. Every model page includes typical specifications, applications and the questions to settle before ordering.

Common questions
The questions buyers ask first.
A short answer now, and a project-specific datasheet when the load case is clear. If the question is not here, the inquiry form is the fastest route.
Ask an engineering questionWhat transformers does Fengguang manufacture?
Which standards are the transformers designed to?
Can the transformer be adapted to a hot, humid or high-altitude site?
How do I choose between oil-immersed and dry-type?
How do I request a datasheet or quotation?
Next step
Send the load case. Get a reviewed design basis.
Share the application, voltage class, capacity, site conditions and required documents. The team checks the transformer family, the cooling margin and the interface before a quotation is issued.
