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 check the product before use?

Check packing condition and appearance against test certificate. Ensure ceramic envelope is integrated. Test power frequency withstand voltage before operation. Clean surface with dry or alcohol-damped cloth.

Q:What is the test procedure for vacuum interrupter?

Apply 70 percent of rated power frequency withstand voltage between open contacts for 1 minute. Qualified if no sudden change or trip phenomena occur.

Q:How to mount the vacuum interrupter?

Clean surface with cotton or alcohol-dipped silk cloth. Clean conducting poles for good contact. Adjust interrupter to match equipment specifications.

Q:What precautions during mounting?

Provide guide unit for operation. Ensure coaxality of moving pole. Do not strike envelope with hard objects. Avoid twisting moving pole or over-pressing bellows.

Q:How to maintain the vacuum interrupter?

Periodically check power frequency withstand voltage. Monitor contact burnout. Replace when burnout mark appears on moving conducting pole indicating end of electrical endurance.
