AI-Powered supplier vetting
SummaryThe supplier is a limited company with 513 employees and no stated parent group. It offers oil-immersed and dry-type transformers, transformer substations, and high- and low-voltage switchgear. Production evidence includes four production lines, stated annual output for several product categories, broad export coverage, and off-peak lead time within 15 workdays. The supplier demonstrates R&D, ODM, OEM, private-mold, 3D design, and sample/design customization capabilities, but has no available SDK. Certifications include ISO 9001:2015, ISO 45001:2018, ISO 14001, CE, and UL. Overseas agents or branches, inventory capability, and participation in ELEKTRO 2026 are reported, while overseas warehouses and showrooms are unavailable. Financial information is identified for 2023–2025, but no financial performance values are provided. Customer references are limited to stated OEM service for popular brands.
Supplier typeThe supplier is a limited company, is not stated to belong to a larger company group, and operates in power equipment and electrical-component sales, including transformers, switchgear-related equipment, and associated electrical products. This identifies a specialized electrical equipment supplier rather than a general trading entity, although the stated number of cooperative suppliers is zero and the business scope excerpt is incomplete.
CertificationsThe supplier reports ISO 9001:2015, ISO 45001:2018, and ISO 14001 certifications, along with CE and UL product-certification capability. These explicitly support quality, occupational-safety, environmental-management, and product-compliance capabilities.
After-Sales capabilityThe supplier reports 100 qualified service-capability suppliers, documented procedures and records for supplier assessment, and a corrective and preventive action mechanism. It also has inventory capability and overseas agents or branches serving Tanzania, Zambia, Ghana, and other countries, but has no overseas warehouse or showroom; the available evidence supports service infrastructure but not complete global after-sales coverage.
R&D capabilityThe supplier reports private-mold R&D, professional technical-supplier capability, 3D software design, new products within the past year, ODM services, and OEM services for popular brands. However, it explicitly has no available SDK, so innovation capability is demonstrated in product and design development but not across all technical interfaces.
Production capacityThe supplier operates four production lines and reports output of 6,000 substations, 10,000 oil transformers, 5,400 switchgear units, and 11,000 dry-type transformers, with off-peak lead time within 15 workdays. It has in-stock capability and broad export markets, but no valid contract with an associated subcontractor, which is a stated manufacturing-governance gap.
Customization capabilityThe supplier explicitly provides customization from samples and designs, private-mold development, 3D software design services, ODM, and OEM services. These capabilities directly support customized product development and manufacturing.
