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 vacuum interrupter before putting it into use?

Check if packing is in good condition and appearance matches the test certificate. Ensure the ceramic envelope is integrated when shaking. Test power frequency withstand voltage before operation. Clean the surface with a dry or alcohol-damped cloth. Apply 70% of rated power frequency withstand voltage between open contacts for 1 minute; the unit is qualified if there is no sudden change or trip.

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

Clean the surface with cotton or alcohol-dipped silk cloth before mounting. Ensure the conducting pole and electric connection surface are clean for good contact. Adjust the interrupter to align with equipment specifications. Provide a guide unit during operation to ensure coaxality. Do not apply torque force on the bellows.

Q:What should be avoided during the mounting process?

Do not beat or strike the interrupter envelope with hard objects to prevent cracks and air leakage. Do not disassemble the interrupter repeatedly to avoid screw slipping. Avoid twisting the moving conducting pole or applying excessive pressure on the bellows to prevent torque force and scratches that reduce service life.

Q:How to periodically check the vacuum interrupter during application?

Periodically check the vacuum interrupter using the power frequency withstand voltage method. Also, check the contact burnout status. If the burnout mark reaches the moving conducting pole, the electrical endurance is finished and the unit must be replaced.

Q:What is the shelf life of the vacuum interrupter?

The vacuum interrupter has a shelf life of 20 years.
