AI-Powered supplier vetting

SummaryThe supplier demonstrates established manufacturing, quality-management, export, customization, and service-process capabilities. Evidence includes five precision-transformer automation production lines, ERP integration, ISO and product certifications, 18 years of export experience, in-house import/export rights, and documented complaint and corrective-action procedures. It offers ODM and SDK-related capabilities, but reported no new products in the past year and does not provide OEM services for popular brands. Manufacturing capacity is not supported by a valid contract with the factory or related subcontractor. Overseas warehouse and showroom services are unavailable, while inventory capability, international quotation/payment options, and lead times within 15 working days are documented. Financial assessment is inconclusive because the provided figures are not interpretable without units or context.

Supplier typeThe supplier is evidenced as a manufacturer with five precision-transformer automation production lines, ERP-enabled production integration, in-stock capability, ODM availability, and in-house import/export rights. However, the absence of a valid manufacturing-capacity contract with its factory or related subcontractor is a documented structural limitation.

CertificationsThe supplier reports ISO9001:2015, ISO14001, and ISO45001:2018 management-system certifications, along with CE and RoHS product-compliance certifications. Its quality-system certification history extends back to ISO9001 certification and includes the 2015 version obtained in 2018.

After-Sales capabilityWritten and followed procedures are documented for service assessment, corrective and preventive actions, and customer complaints, supporting structured after-sales handling. Inventory capability, accepted international service terms, and lead times within 15 working days are also reported, although overseas warehouse and showroom services are unavailable.

Production capacityFive precision-transformer automation production lines, ERP-based information integration, inventory capability, 21 qualified service-capability suppliers, and peak- and off-season lead times within 15 working days support substantial operational capability. The lack of a valid contract with the factory or related subcontractor is an explicit production-capacity governance deficiency.

Customization capabilityThe supplier supports customization from customer designs and full customization, and also offers ODM services. It does not provide OEM services for popular brands, which limits applicability for brand-specific OEM programs but does not negate its general customization capability.

Client casesThe supplier reports collaboration with Fortune 500 companies and a repeat-buyer preference rate of 30%–50%. It also reports recognition as a Hubei brand-name product and well-known trademark, but the provided slices do not identify customer names, project details, or verifiable case outcomes.

Product Q&A

Q:Can the current transformer be installed without cutting the cable?

Yes, the split-core design allows for 180-degree opening and closing, enabling quick installation and disassembly without power failure or continuous line interruption.

Q:What is the rated input current range?

The rated input current ranges from 0 to 1500A, with a primary current range of 1-1000A and transformation ratios from 100:1 to 10000:1.

Q:What accuracy classes are available?

The product is available in 0.5 and 1.0 accuracy classes to meet different measurement precision requirements.

Q:What output interfaces are supported?

It supports various output methods including PVC sheathed wire terminals, RJ12 crystal terminals, PS/2 round head male interfaces, and three-phase integrated collection terminals.

Q:What materials are used for the shell and core?

The shell is made of PA/PC with a 94-V0 flammability rating, and the core material is silicon steel or manganese zinc ferrite.
