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.

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.

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 question
What transformers does Fengguang manufacture?
Fengguang manufactures oil-immersed distribution and power transformers from 50 to 10,000 kVA, cast-resin dry-type transformers from 30 to 2,500 kVA, 110 kV and 220 kV power transformers up to 120 MVA, YB/ZGS prefabricated substations, switchgear and liquid-cooled energy-storage cabinets.
Which standards are the transformers designed to?
The design basis is GB 1094.1, GB/T 6451 and the IEC 60076 series. Dry-type units follow IEC 60076-11 and prefabricated substations follow IEC 62271-202 / GB/T 17467. Routine test reports are supplied with each unit; type and special tests can be witnessed.
Can the transformer be adapted to a hot, humid or high-altitude site?
Yes. Ambient temperature, altitude, dust, humidity and salt spray are design inputs. The specification can include C4/C5 corrosion systems, IP54 enclosures, anti-condensation heaters, high-temperature cooling margins, 60 Hz designs and stainless-steel hardware.
How do I choose between oil-immersed and dry-type?
Oil-immersed is usually the better fit for outdoor sites, higher capacities and lower first cost. Dry-type is preferred where fire safety, indoor installation or oil containment is the deciding constraint. Both can be quoted against the same load case.
How do I request a datasheet or quotation?
Use the inquiry form on this site. Include the application, capacity, voltage ratio, frequency, ambient conditions, required standards and documents. The team reviews the design basis before issuing the datasheet and 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.
