How can I determine if the vacuum interrupter needs replacement?

Periodically check the contacts for burnout. If the burnout mark on the moving conducting pole is reached, the electrical endurance is finished and it should be replaced.

Is OEM or ODM service available for this product?

Yes, both OEM and ODM services are available.

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:What is the shelf life of the vacuum interrupter?

The vacuum interrupter has a shelf life of 20 years.

Q:How many mechanical operations can the interrupter perform?

It is designed for 30,000 mechanical operations.

Q:What should be checked before putting the product into use?

Check if the packing is in good condition, verify the appearance against the test certificate, ensure the ceramic envelope is integrated, and test the power frequency withstand voltage.

Q:How should the surface be cleaned before testing or mounting?

Clean the surface with a dry cloth or an alcohol-damped cloth before testing, and use cotton or an alcohol-dipped silk cloth before mounting.

Q:What precautions should be taken during mounting?

Ensure the guide unit is provided, maintain coaxality of the moving conducting pole, avoid torque on the bellows, and do not strike the envelope with hard objects.
