AI-Powered supplier vetting

SummaryHV Hipot Electric Co., Ltd. is a China-based factory and limited company in Wuhan, Hubei, established in 2006 according to the company profile, while another description states operations began in 2003. It manufactures high-voltage testing and related electrical measurement equipment, including AC/DC hipot testers, partial-discharge testers, and circuit-breaker testers. The supplier reports ISO9001:2015 and ISO14001:2015 certifications, three production lines, 6–10 quality-control staff, and eight years of R&D-engineer experience; another statement reports 18 technicians in its R&D team. It serves multiple overseas markets and accepts LC and T/T payment terms, with stated one-month lead times in both peak and off-peak seasons. Evidence supports established technical and manufacturing capabilities, but after-sales service, customization, and specific customer cases are not sufficiently documented.

Supplier typeThe supplier is identified as a limited company, a factory, and a manufacturing enterprise located in Wuhan, China. Its business focuses on instruments, meters, electrical and electronic products, particularly high-voltage testing equipment.

CertificationsThe supplier explicitly reports ISO9001:2015 and ISO14001:2015 certificates, while another company description confirms ISO9001 quality management certification and high-tech enterprise qualifications. These statements provide direct evidence of formal quality and environmental management credentials.

R&D capabilityThe supplier reports successive development of multiple high-voltage testing products, participation in high-voltage and energy-saving projects with State Grid-related organizations, research institutions, and Wuhan University, and an R&D team described as 18 technicians. These are explicit indicators of product-development and technical innovation capability.

Production capacityThe supplier operates as a factory with three production lines, 6–10 quality-control staff, a 2,712 m² manufacturing plant, and stated one-month order fulfillment in both peak and off-peak seasons.

Product Q&A

Q:Can this tester measure three-phase windings simultaneously?

Yes, the GDZRS-20A is designed to test three-phase winding DC resistances at the same time, which significantly reduces working time and labor intensity.

Q:Is discharge required for on-load variable transformers?

No, for on-load variable transformers, there is no need to discharge; you can just adjust the tap switch directly.

Q:How much data can be stored and printed?

The device has a data saving capacity of 150 groups and includes a built-in panel printer for easy result retrieval and storage.

Q:What are the available current options?

Single Phase options are 1A, 5A, 10A, 20A, and 40A. Three Phase options are 1A, 5A, 10A, and 20A.

Q:Is this product customizable?

No, the product is listed as Non-Customized.
