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 standards does the test cell structure follow?

The test cell adopts a three-electrode structure according to the national standard GB/T5654-2007, with an electrode spacing of 2mm to eliminate stray capacitance and leakage effects.

Q:How does the instrument ensure measurement accuracy over time?

It uses an internal SF6 gas-filled three-electrode standard capacitor whose dielectric loss and electrical capacity are not affected by ambient temperature or humidity, ensuring long-term accuracy.

Q:What temperature control method is used?

The instrument uses medium frequency induction heating combined with a PID temperature control algorithm, allowing for non-contact, uniform, and fast heating with strict temperature error control.

Q:What protection functions are included?

It features protection against over-voltage, over-current, and high-voltage short circuits by quickly cutting off high voltage. It also warns if the temperature sensor fails or is disconnected, and stops heating if the temperature exceeds 120 degrees.

Q:What is the warranty period for this tester?

The product comes with a 1-year warranty.
