One design review before production
Transformer failures are rarely caused by the nameplate alone. They come from a mismatch between the site conditions, the protection scheme and the design. Fengguang reviews the load profile, fault level, ambient temperature, altitude, grid code and transport limits before releasing the drawing.
Test reports that match the unit
Every transformer is routine-tested. Winding resistance, ratio, impedance, no-load loss, load loss, insulation resistance and power-frequency withstand are recorded against the approved datasheet. Type and special tests can be witnessed. The test report travels with the unit, not in a separate email chain.
A complete distribution package
Buyers increasingly want one interface for the transformer, MV switchgear, LV board and enclosure. Fengguang supplies oil-immersed and dry-type transformers, YB/ZGS substations, GGD/MNS/GCS switchgear and energy-storage cabinets, so the interfaces can be coordinated before shipment.
Export documentation and packing
English drawings, material certificates, test reports, installation manuals and packing lists are prepared for each shipment. Export packing accounts for sea freight, humidity and long storage. Spare-parts and commissioning support can be included in the scope.
Environmental adaptation
For hot, humid, dusty, high-altitude or coastal sites, the design can include C4/C5 corrosion systems, IP54 enclosures, anti-condensation heaters, high-temperature cooling margins, 60 Hz designs and stainless-steel hardware. These are engineering choices, not catalogue options.
