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 circuit breakers can this analyzer test?

It is suitable for SF6 switches, GIS combination electrical appliances, vacuum switches, oil switches, vacuum contactors, and special train circuit breakers.

Q:What parameters can be measured during a single operation?

It obtains data and waveforms including time, bounce number and time, speed, coil current, and coil resistance.

Q:Does the device require external power for operation?

No, it features an integrated operation power supply with a built-in DC20-270V adjustable power supply, eliminating the need for site secondary power.

Q:Can the linear sensor length be adjusted?

Yes, the linear sensor length can be arbitrarily set from 30mm to 1000mm without needing to return the instrument to the factory.

Q:How much test data can the main unit store?

The host can store 100 groups of test data and includes a real-time clock for easy archiving.
