AI-Powered supplier vetting

SummaryWUHAN FEITE ELECTRIC CO., LTD. is presented as an electrical and electronics supplier specializing in vacuum interrupters, embedded poles, circuit breakers, switchgear, switches, and contactors. The stated manufacturing plant area is 23,095 m², with more than 10 production lines and annual output of 600,000 pieces across relevant product categories. The supplier reports ISO 9001:2015 certification, 5 years of R&D engineer experience, and 6–10 quality-control staff. Export activity reportedly began in 2012, with exports representing 11%–20% of total sales. Trade records show shipments of multiple medium- and high-voltage vacuum interrupter models to a buyer in India through Shanghai. Evidence is insufficient to assess after-sales service, financial credibility, and customization capability. The identified customer transactions support customer-case evidence, but the available records show only one named buyer.

Supplier typeThe supplier is identified as an electrical and electronics manufacturer focused on vacuum interrupters, vacuum embedded poles, circuit breakers, switchgear, switches, arc-extinguishing chambers, and contactors. Its stated production output and operation of more than 10 production lines support classification as a specialized manufacturing supplier rather than a purely trading entity.

CertificationsThe supplier reports holding an ISO 9001:2015 certificate. This is explicit evidence of a certified quality-management system, although the provided information does not include certificate scope, issuing body, validity period, or product-specific certifications.

Production capacityThe supplier states a 23,095 m² manufacturing plant, more than 10 production lines, and annual output of 600,000 pieces covering vacuum interrupters, embedded poles, circuit breakers, contactors, and related products. These explicit capacity indicators support a positive assessment of production capability.

Client casesThe records associate WUHAN FEITE ELECTRIC CO., LTD. with SHREEM ELECTRIC LIMITED and show several vacuum interrupter transactions, including 12 kV and 36 kV models, with imports listed from India and Shanghai as the origin port. This provides explicit evidence of at least one identifiable buyer relationship and product shipment activity, although the available evidence does not establish the total customer base or customer satisfaction.

Product Q&A

Q:How to precheck the vacuum interrupter before use?

Check if the packing is in good condition and if the appearance matches the test certificate. Ensure the ceramic envelope is integrated when shaking. Clean the surface with a dry or alcohol-damped cloth. Test power frequency withstand voltage by applying 70% of rated voltage for 1 minute; no sudden change or trip phenomena indicates qualification.

Q:What are the mounting requirements for the vacuum interrupter?

Clean the surface with cotton or alcohol-dipped silk cloth before mounting. Ensure the conducting pole and electric connection surfaces are clean for good contact. Adjust the interrupter to align with the equipment and ensure mechanical data meets specifications.

Q:What precautions should be taken during mounting?

Provide a guide unit during operation. Ensure coaxality of the moving conducting pole and interrupter axial line. Do not apply torque force on the bellow. Avoid striking the envelope with hard objects to prevent cracks. Ensure the conducting pole is vertical on the fixed end face. Do not disassemble repeatedly or apply twisting/over-pressing force to the bellow.

Q:How to apply the vacuum interrupter and check its condition?

Periodically check the vacuum interrupter using power frequency withstand voltage. Monitor contact burnout; if the moving conducting pole shows burnout marks, the electrical endurance is finished and it must be replaced.

Q:What are the main technical parameters of this vacuum interrupter?

Rated voltage is 40.5kV, rated current is 1250A, and rated frequency is 50Hz. It has a mechanical life of 30,000 times and a shelf life of 20 years. Rated short-circuit withstand current is 20/25kA.
