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?

Precheck includes verifying packing condition, appearance, and correspondence with the test certificate. Shake the interrupter to ensure the ceramic envelope is integrated. 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 mounting requirements for the vacuum interrupter?

Clean the surface with cotton or alcohol-dipped silk cloth before mounting. Ensure the conducting pole and connection surfaces are clean for good contact. Adjust the interrupter to match equipment specifications. Provide a guide unit during operation to ensure coaxality. Do not apply torque on the bellow or strike the envelope with hard objects.

Q:What precautions should be taken during mounting?

Ensure the moving conducting pole is coaxial with the interrupter and vertical to the fixed end face. Avoid repeated disassembly to prevent screw slippage. Do not twist the moving pole or over-press the bellow to avoid torque and scratches. Ensure applied force does not exceed the static relief pressure stipulated in the specification.

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

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

Q:What is the rated voltage and current for this product?

The rated voltage is 40.5 kV and the rated current is 3150 A. It operates at a frequency of 50 Hz.
