AI-Powered supplier vetting

SummaryThe supplier is a limited company offering vacuum circuit breakers, auto reclosers, power transformers, operating mechanisms, voltage transformers, and switchgear. It reports ISO 9000/9001 and ISO 14000/14001 certifications, an internal IEC/CNAS-standard testing laboratory, and substantial production and overseas-market experience as described by the supplier. It provides extensive customization and ODM services, has launched new products, and offers OEM services to recognized brands. Quality controls include 100% finished-product inspection, raw-material traceability, quality assurance, and documented corrective and preventive action procedures. Overseas service coverage includes installation, debugging, maintenance, repair, and training in six listed countries, but it has no overseas warehouses, showrooms, agents, or branches. Financial information is limited to year labels without performance values, so financial credibility cannot be assessed. Fire-drill and environmental-assessment status are also...

Supplier typeThe supplier is identified as a limited company. Its stated product scope covers several electrical equipment categories, while its licensed business scope includes electrical installation services subject to required approvals.

CertificationsThe supplier reports ISO 9000, ISO 9001, ISO 14000, and ISO 14001 certifications. It also describes an IEC/CNAS-standard testing laboratory within its factory, although the provided information does not include certificate numbers or validity details.
