Supplier typeThe supplier is identified as Guangdong Forui Electric Co., Ltd., a professional manufacturer of electric power equipment with integrated R&D, production, sales, and service departments. Its stated product keyword is Transformer, indicating a manufacturing-oriented supplier rather than only a trading or service intermediary.

After-Sales capabilityThe supplier has documented customer-complaint handling and corrective/preventive-action procedures, accepts multiple service quotation terms, and reports lead times within 15 workdays in both peak and off-season. However, it has no overseas agents or branches, no overseas showroom, no overseas warehouse, and reports zero countries with overseas service coverage, limiting demonstrated international after-sales reach.

R&D capabilityThe supplier reports new products within the past year, integrated R&D capability, three years of total R&D-engineer experience, and ODM services. It also reports no available SDK, but SDK availability is not necessarily required for transformer manufacturing; the evidence supports product-development capability while not establishing a broad technology platform capability.

Production capacityReported production resources include a 6,468.0 m² plant, four production lines, specified transformer-related equipment, annual transformer output of 100,000 pieces, in-stock capability, and valid manufacturing contracts with associated subcontractors. Three quality assurance inspectors and six to ten quality-control staff are also reported, providing explicit evidence of established production capacity.

Customization capabilityThe supplier explicitly supports customization from samples, customization from designs, full customization, minor customization, and flexible customization. These capabilities are stated in both the R&D and design-service information, indicating broad customization coverage.

Client casesNamed customer or institutional references include Country Garden Real Estate, Sinopec, and Hunan University of Science and Technology. The slices do not specify order details, product scope, dates, or whether these entities are current customers, so the references support some evidence of customer experience but cannot establish the depth or relevance of each case.
