AI-Powered supplier vetting

SummaryWuhan Hertz Power Equipment Co., Ltd. is an electrical and power equipment manufacturer, seller, repair provider, and technical service supplier based in Wuhan, China. It holds ISO9001:2015 and ISO14001:2015 certificates, reports available SDK capability, design-based customization, four production lines, inventory capability, and documented finished-product inspection instructions. Its stated product output includes cable fault locators, transformer oil hipot testers, relay protection testers, power frequency test devices, and series resonance AC test sets. The supplier exports primarily to North America, with exports representing 51%–70% of total sales and seven years of export experience. However, it reports no valid manufacturing-capacity contract with related subcontractors, no overseas warehouse or showroom, no outsourcing SOP, and no continuous quantity reconciliation for each batch. Evidence of customer cases and after-sales execution is insufficient.

Supplier typeThe supplier is identified as a China-based manufacturer and seller of instruments, electrical and power equipment, and mechanical equipment, with repair, research and development, software, and technical service activities. Its registered and physical addresses are the same Wuhan location, supporting classification as an equipment manufacturer and technical-service provider.

CertificationsThe supplier reports holding ISO9001:2015 and ISO14001:2015 certificates. These explicitly demonstrate quality-management and environmental-management certification, although no certificate scope or validity dates are provided.

R&D capabilityThe supplier reports available SDK capability and includes equipment research and development, software development, technology development, consultation, and technical exchange in its scope. These facts support technical-development capability, but no R&D investment, patent, product-development record, or engineering-team scale is provided.

Production capacityThe supplier reports four production lines, inventory capability, and stated annual product outputs across five categories, including 500 cable fault locators, 1,000 transformer oil hipot testers, 1,000 relay protection testers, 800 power frequency test devices, and 500 series resonance AC test sets. Capacity controls have weaknesses: there is no valid manufacturing-capacity contract with related subcontractors, no continuous batch quantity reconciliation, and no outsourcing SOP.

Customization capabilityThe supplier explicitly reports customization from customer designs. This is direct evidence of design-based customization capability, although the available information does not specify engineering scope, tooling capability, lead times, or customization limitations.

Product Q&A

Q:How many samples can be tested simultaneously?

The tester can test up to 8 insulating boots or gloves simultaneously and measure the leakage current of each sample individually.

Q:What is the testing method for insulating boots?

It uses a dry-type testing method with small steel balls placed inside the shoes, eliminating the traditional water-filling method.

Q:Does the device support automatic testing?

Yes, it features a high-precision stepper motor for fully automatic withstand voltage testing, including auto voltage boost, hold, timing, and reduction.

Q:What happens if a single channel fails during testing?

Each channel has an independent disconnect mechanism; if a breakdown occurs, that specific channel cuts off without stopping tests on other samples.

Q:Is the transformer ratio adjustable?

Yes, the transformation ratio of the test transformer can be freely configured to match transformers already owned by customers.
