AI-Powered supplier vetting

SummaryROGOWSKI TECHNOLOGY (SHANGHAI) CO., LTD. is a China-based limited company established in 2018 and located in Minhang, Shanghai. The available information identifies it as a factory engaged in electrical and electronics products, including Rogowski coils, integrators, power meters, current sensors, and power quality systems. Evidence supports a formal ISO 9001:2015 management certification, six production lines, a reported Rogowski coil output of 400,000 pieces annually, and export activity across several regions. The supplier states proprietary intellectual property and integrated R&D, production, and sales capabilities, but the evidence is partly inconsistent across company names and staffing figures. No direct evidence establishes after-sales service systems, customer cases, customization services, or comprehensive financial credibility.

Supplier typeThe supplier is identified as a factory and a limited company based in Minhang, Shanghai, China, with electrical and electronics trade activities and products centered on Rogowski coils, integrators, power meters, and related measurement equipment. The description also presents an integrated R&D, production, and sales model, although one company-description slice names a different entity.

CertificationsThe supplier is explicitly reported to hold an ISO 9001:2015 certificate, providing direct evidence of a certified quality management system.

R&D capabilityThe company description claims professional R&D capability and proprietary intellectual property, while the product list includes multiple Rogowski coil, integrator, power-meter, and cloud power-quality solutions. Two years of R&D engineer experience are also reported, but no patents, development results, or technical investment details are provided.

Production capacityThe supplier reports an 897.0 m² manufacturing plant, six production lines, and annual Rogowski coil output of 400,000 pieces. It also states delivery within 15 working days in both off-peak and peak periods, although the reported overall annual-output information is internally inconsistent with the product-specific output data.
