AI-Powered supplier vetting

SummaryShenheng Power Equipment Co., Ltd specializes in high- and low-voltage power transmission and distribution equipment, including switchgear, ring main units, cable branch boxes, and box-type substations. It reports ISO9001:2015, ISO45001:2018, ISO14001, and CE certification. Production controls include 100% finished-product inspection and 10 quality assurance and control inspectors, with stated annual capacities across several product categories. The supplier provides ODM, OEM, and sample-based customization services, but reports no new products in the past year and no available SDK. Service capability is supported by documented supplier assessment, corrective-action, and complaint-handling procedures, although overseas service infrastructure is absent. Financial information is insufficient for assessing credibility, and no specific customer names or case details are provided.

Supplier typeThe supplier is a specialized manufacturer of high- and low-voltage power transmission and distribution equipment and electrical components. Its stated scope also includes maintenance and testing of power facilities, construction-related projects, and wire and cable manufacturing subject to applicable approvals.

CertificationsThe supplier reports ISO9001:2015, ISO45001:2018, and ISO14001 management-system certifications, together with CE product compliance certification. These stated certifications explicitly support its qualification in quality, occupational safety, environmental management, and product compliance.

After-Sales capabilityThe supplier has documented procedures and records for supplier-service assessment, corrective and preventive actions, and customer complaint handling, and lists debugging and maintenance services. However, it reports no overseas warehouses, showrooms, agents, branches, or overseas-service countries, limiting evidence of international service coverage.

R&D capabilityThe supplier reports ODM capability and OEM service for well-known brands, indicating product-development support and manufacturing collaboration. Nevertheless, it reports no new products during the past year and no available SDK, so evidence of recent product innovation and software-development capability is weak.

Production capacityThe supplier operates laser-cutting, bending, and CNC-machining facilities, performs 100% finished-product inspection, and reports 10 quality assurance and quality control inspectors. It also states annual capacities for switchgear, substations, vacuum circuit breakers, and oil-immersed transformers, providing explicit evidence of established manufacturing capability.

Customization capabilityThe supplier explicitly offers ODM services and customization from samples, demonstrating both design-manufacturing collaboration and sample-based product adaptation. Its OEM experience for well-known brands further supports the stated ability to produce customized products.
