AI-Powered supplier vetting

SummaryThe supplier is a technology-driven enterprise integrating R&D, production, sales, and after-sales service, offering electrical testing equipment, specialized tools, meters, and related products. It reports new products within the past year, ODM capability, broad customization options, and OEM service for well-known brands. Overseas service is stated for Vietnam and Russia, including installation, debugging, maintenance, repair, and training, but the supplier has no overseas warehouses, showrooms, agents, or branches and has not participated in offline trade shows. Quality assurance and raw-material traceability are reported, while several service-control procedures lack written records. Financial information is inconsistent and insufficient for assessment.

Supplier typeThe supplier identifies as a technology-driven enterprise integrating R&D, production, sales, and after-sales service. Its listed products include electrical tools, intelligent meters, energy measurement equipment, fault-location and cable-testing equipment, and specialized instruments, indicating a manufacturer-oriented technology supplier.

After-Sales capabilityThe supplier states that it provides after-sales service and offers installation, debugging, maintenance, repair, and training in Vietnam and Russia. However, it has no overseas warehouse, showroom, agent, or branch, has not participated in offline trade shows, and its complaint-handling and service corrective-action procedures have no written records, limiting evidence of formal service execution controls.

R&D capabilityThe supplier reports R&D capability, new products within the past year, ODM services, and integration of R&D with production and after-sales service. It does not have an available SDK, but the available evidence still explicitly supports product-development capability.

Production capacityThe supplier is described as integrating production with R&D, sales, and after-sales service, and it lists a broad product range including tools, meters, and testing equipment. Quality assurance and raw-material traceability are reported, but the slices do not provide production capacity, factory scale, or output data.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. It also reports ODM service, providing direct evidence of broad customization capability.

Product Q&A

Q:What types of tests does this CT/PT Analyzer perform?

It performs excitation characteristics, ratio, polarity, secondary winding resistance, secondary burden, ratio error, phase displacement, and knee point voltage tests for various CTs and PTs.

Q:How is test data stored and transferred?

The instrument can store 2000 groups of test data that are retained even after power loss. Data can be copied to a PC via USB disk for analysis and conversion into WORD reports.

Q:Is the device portable for field use?

Yes, it is designed for easy carrying with a weight of less than 9kg and compact dimensions, making it suitable for on-site transformer testing.

Q:What international standards does the tester comply with?

It meets IEC60044-1, IEC60044-2, IEC60044-6, C57.13, IEC61869-2, and IEC61869-3 standards, automatically selecting the appropriate test based on transformer type.

Q:What is the warranty period for this product?

We provide a one-year warranty for this product, along with provided after-sales service support.
