Jiangsu Fengguang Transformer Co., Ltd. manufactures oil-immersed transformers, dry-type transformers, prefabricated substations, switchgear and energy-storage cabinets for projects in more than 50 countries.
The company operates a plant of nearly 15,000 m² with more than 20 production and test units. The product range covers 50 to 10,000 kVA distribution transformers and extends to 110 kV and 220 kV power transformers for grid and industrial projects. Core capability includes silicon-steel cutting, winding, vacuum casting, tank fabrication, vacuum oil filling, routine testing and packing for export.
Fengguang is a National High-Tech Enterprise and a qualified supplier to State Grid and China Southern Power Grid. The quality system is certified to ISO 9001, ISO 14001 and ISO 45001, and products carry CE marking where applicable. Designs follow GB 1094.1, GB/T 6451 and the IEC 60076 series, with routine test reports supplied for every unit.
What we build
- Oil-immersed distribution and power transformers: S11, S13, S20 and S22, 10 kV to 35 kV, 50-10,000 kVA.
- Dry-type transformers: SC(B)10, SC(B)13, SC(B)14, SC(B)18 and SC(B)H15 amorphous alloy, 30-2,500 kVA.
- Prefabricated substations: YB and ZGS, 12 kV and 40.5 kV, 250-6,500 kVA.
- Switchgear and energy-storage integrated cabinets for complete distribution and BESS projects.
How we work
Every project starts with a specification review: load profile, voltage class, fault level, ambient conditions, grid code and transport limits. The approved datasheet and drawing become the inspection basis. Buyers can witness routine tests, review material certificates and receive a document package with the shipment.
For export projects, the team supports English-language drawings, third-party inspection, export packing, spare-parts planning and remote commissioning. The objective is a transformer that arrives with the right documents and operates predictably in the site conditions.
