AI-Powered supplier vetting

SummaryThe supplier is identified as Wenzhou Ubright Electric Co., Ltd., a China-based limited company in Zhejiang operating in electrical and electronics. Its stated product range covers medium- and high-voltage equipment, transformers, substations, switchgear, vacuum circuit breakers, and components for photovoltaic and energy-storage applications. The company reports three-system certification, quality-management and continuous-improvement practices, more than 10 production lines, 11–20 quality-control staff, a manufacturing area of approximately 13,293 m², and stated annual output of 10,000 VS1 vacuum circuit breaker sets. It reports exports beginning in 2012 and sales coverage across Asia and other countries. However, the supplied records contain inconsistencies regarding establishment date, legal identity, business type, and production-output figures, and provide insufficient evidence on after-sales service, customization, and specific customer cases.

CertificationsThe company explicitly states that it has obtained three system certifications: Quality Management, Occupational Health and Safety Management, and Environmental Management. This is direct evidence of certification holding.

Financial creditThe company is reported to have received AAA credit-enterprise ratings for consecutive years and several enterprise honors. However, the records also contain conflicting establishment and identity information, so the credibility evidence cannot be fully validated from the supplied material alone.

R&D capabilityThe supplier describes itself as engaged in R&D and product promotion, continuous improvement, science-and-technology-based development, and products for photovoltaic and energy-storage applications. These statements provide explicit evidence of innovation-oriented activity.

Production capacityThe records report a manufacturing area of approximately 13,293 m², more than 10 production lines, 11–20 quality-control staff, and annual VS1 vacuum circuit breaker output of 10,000 sets. Export activity is also reported, although production and company-profile figures are not fully consistent across the slices.
