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. It also reports self-operated import and export rights and serves several overseas markets, supporting a positive assessment of production and delivery capability.

Product Q&A

Q:What types of transformer faults can this analyzer detect?

It detects winding movements and mechanical failures such as distortion, bulging, shifting, tilting, inter-turn short circuits, and inter-phase contact short circuits.

Q:Does the device support wireless communication?

Yes, it features an optional wireless WIFI interface for connecting with a laptop, in addition to the standard USB interface.

Q:How does the analyzer analyze winding deformation?

It compares A, B, C-phase similarities and contrasts current data with original data to classify results as normal, mild, moderate, or severe deformation.

Q:What is the scanning frequency range of the instrument?

The linear scanning range is 1kHz to 2MHz, and the segment frequency scanning range is 0.5kHz to 1MHz.

Q:Can the device generate reports automatically?

Yes, it automatically analyzes test results and generates electronic Word documents for saving and printing.
