AI-Powered supplier vetting

SummaryShanghai Longliyuan Electric Power Technology Co., Ltd. is a China-based limited company established in 2022, supplying Active Harmonic Filters, Static Var Generators, SVGs, and AHF products. It reports a Shanghai location, 11 employees, production facilities in Hangzhou and Xinxiang, and stated workshop areas of 1,800 m² and over 15,000 m² in different records. The supplier describes an R&D foundation linked to Shanghai Jiao Tong University, national patents, proprietary technologies, and integrated R&D, manufacturing, and quality assurance operations. It states that products comply with international and domestic certifications and that it operates more than 10 worldwide service centers. However, the management-system certification field is recorded as NIL, audit results and several operational capabilities are unclear, and customer collaboration evidence is not available. Export sales are reported at 41%–50%, although the primary export market is separately listed as domestic.

Supplier typeThe supplier is identified as a combined business entity and limited company headquartered in Shanghai, China, operating in the Electrical & Electronics sector. Its stated products are Active Harmonic Filters, Static Var Generators, SVGs, and AHF products.

After-Sales capabilityThe supplier explicitly reports more than 10 service centers worldwide providing localized technical support and after-sales service. This is direct evidence of an established international after-sales service network.

R&D capabilityThe supplier describes a research foundation associated with Shanghai Jiao Tong University, an R&D team of academic and industry experts, national patents, proprietary technologies, and integrated R&D operations. However, the structured R&D capability fields and number of new products launched are marked unknown, so the scale and current output of innovation activity remain only partially verified.

Production capacityThe supplier reports production bases in Hangzhou and Xinxiang, stated workshop areas of 1,800 m² and over 15,000 m² in separate records, a lead time within 15 workdays off-season and one month during peak season, and an SGS audit record. However, outsourcing procedures, manufacturing contracts, inventory capacity, and overseas warehousing are unknown, while the differing facility-area figures reduce precision.
