AI-Powered supplier vetting

SummaryThe supplier is a manufacturer and seller of power distribution switch-control equipment, hardware, mechanical and electrical equipment, molds, software, and related technical services. It reports ISO9001, ISO14001, and ISO45001 certifications, more than 10 production lines, 35 years of combined R&D engineer experience, and 41–50 quality-control staff. It offers multiple customization modes, ODM, and OEM services for known brands, but reported no new products in the past year and no available SDK. Service management procedures and corrective-action records are documented, while overseas service infrastructure is limited: no overseas warehouse, showroom, agent, or branch, and zero countries listed for overseas services. Financial records are identified for 2023–2025, but no assessable financial results are provided. The supplier attended a 2025 European Energy Week exhibition and reports one-month lead times in both peak and off-season.

Supplier typeThe stated business scope covers manufacturing, sales, R&D, and technical services for power distribution switch-control equipment, hardware, mechanical and electrical equipment, molds, and software. This directly identifies the supplier as a diversified manufacturer with related engineering and service activities.

CertificationsThe supplier reports ISO9001:2015, ISO14001:2015, and ISO45001 certifications, with ISO9001, ISO45001, and ISO14001 also listed under sustainable development management. UL is listed as a sustainable development and product certification capability, although the slices do not specify its scope or validity details.

Production capacityThe supplier operates more than 10 production lines, has 41–50 quality-control staff, and identifies relay and shunt production lines.
