AI-Powered supplier vetting

SummaryThe supplier operates in power testing products and related electronic, electrical, machinery, software, and information-system activities. It reports 3D design, ODM, OEM, SDK, new-product, and broad customization capabilities, with stated annual productivity of 1,500 sets for four listed testing-equipment categories. Procedures and records exist for corrective/preventive actions and customer complaints, while the supplier explicitly reports no quality assurance in quality-control processes. It has valid manufacturing contracts with associated subcontractors, but no in-stock capacity, overseas warehouse, or overseas showroom. Overseas service offerings include installation, debugging, maintenance, repair, and training, although the stated number of countries served overseas is zero. Financial evidence is incomplete and includes zero values for the listed 2024 financial metrics, so credibility cannot be established from the provided data.

Supplier typeThe supplier is positioned in the power-testing and electrical-equipment sector, with stated activities covering electronic products, software and auxiliary equipment, machinery, instruments, communication equipment, and professional design services. Its company description specifically presents one-stop power testing products and services.

After-Sales capabilityThe supplier has documented and followed procedures for corrective/preventive actions and customer complaints, and lists installation, debugging, maintenance, repair, and training services. However, it reports no overseas warehouse or showroom and zero countries where overseas services are offered, indicating limited demonstrated overseas coverage.

R&D capabilityThe supplier reports new products during the past year, ODM service, OEM service for popular brands, 3D software design, and an available SDK. These are explicit indicators of product-development and technical integration capability.

Production capacityAnnual productivity is stated as 1,500 sets each for four categories of high-voltage and related testing equipment, supported by listed machining, drilling, milling, welding, cutting, and wire-winding facilities. Valid manufacturing contracts with each associated subcontractor are also reported, although no in-stock capacity is available.

Customization capabilityThe supplier explicitly offers customization from samples and designs, full and minor customization, flexible customization, and 3D software design services. The same broad customization range appears in both its R&D and production-related information.

Product Q&A

Q:What is the measurement accuracy of the TTR?

The TTR measurement accuracy is 0.1% for ranges 0.8-3000 and 0.2% for 3000-10000. Voltage accuracy is 0.05% on the HV side and 0.10% on the LV side.

Q:How long does it take to complete a three-phase test?

The device features a high measurement speed, allowing a complete three-phase test within 40 seconds.

Q:What types of transformers can this tester measure?

It is designed for three-phase transformers in power systems, including Z-type, rectifier, electric furnace, non-integral point-shifted, balanced, Scott, and Inverse Scott transformers.

Q:What is the battery life and power source?

It uses a built-in high-capacity chargeable lithium battery. Once fully charged, it can perform more than 500 continuous measurements without external power.

Q:Can the device measure phase angle and tapping positions?

Yes, it measures the phase angle between HV and LV sides. It also has a tapping test function to quickly gauge TTR and error at each tapping switch position.
