AI-Powered supplier vetting

SummaryLiaocheng Kete New Energy Co., Ltd. is identified as a factory manufacturer in Liaocheng, China, operating in electrical and power equipment. Its stated product range includes transformers, box-type substations, switchgear, transmission towers, and new-energy equipment. The company reports integrated R&D, design, production, and construction capabilities, along with ISO 9001, ISO 14001, OHSAS 18001, CCC coverage for 18 low-voltage products, and CQC inspections. It serves power grids, plants, substations, industrial, railway, and construction sectors and reports exports to multiple countries. SGS audit information is provided with a stated validity period, but the audit result is coded rather than explained. Manufacturing-area information is inconsistent across the supplied slices, and most service, innovation-process, quality-control, sustainability, and financial details remain unknown. No financial figures are included.

Supplier typeThe supplier is explicitly identified as a factory located in Liaocheng, China, in the manufacturing industry. Its business scope covers electrical and power equipment, including transformers, substations, switchgear, transmission towers, and new-energy equipment.

CertificationsThe company states that it holds ISO 9001, ISO 14001, OHSAS 18001, and CCC certification for 18 low-voltage products, with products also reported as passing CQC inspections. An SGS audit record is provided for August 29, 2025 to August 28, 2026, although the coded audit result is not interpretable from the supplied context.

R&D capabilityThe supplier describes itself as a National High-Tech Enterprise and reports an integrated R&D, design, production, and construction base supported by technological innovation. However, specific R&D documentation, SDK capability, private-mold development, 3D design services, and other detailed innovation capabilities are marked unknown.

Production capacityThe supplier reports manufacturing power equipment across several product categories and integrated production and construction capabilities, supported by sector applications and international exports. The submitted manufacturing-area data is inconsistent, and outsourcing procedures, manufacturing-capacity contracts, inventory capability, and order-fulfillment details are not sufficiently explained.

Client casesThe supplier identifies served sectors including urban power grids, power plants, substations, oil and chemical, railway, and construction, and reports exports to the United States, Brazil, Peru, Kenya, Ethiopia, India, Myanmar, Vietnam, and other countries. These are market and sector references rather than named customer case studies, so the breadth of customer experience is supported but specific cases are not verifiable.
