How can I determine if the vacuum interrupter needs replacement?

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

Does the product support customization?

Yes, 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:What are the main applications for this product?

It is mainly used in power transmission and distribution control systems, as well as in metallurgy, mining, petroleum, chemical industry, railway, broadcasting, communications, and industrial high frequency heating power distribution systems.

Q:What is the rated voltage and current?

The rated voltage is 12KV and the rated current is 5000A.

Q:How should the vacuum interrupter be checked before use?

Check if the packing is in good condition and if the appearance corresponds to the test certificate. Test the power frequency withstand voltage before operating. Clean the surface with a dry cloth or alcohol-damped cloth.

Q:What precautions should be taken during mounting?

Do not beat or strike the envelope with hard things. Ensure the conducting pole is coaxial and vertical. Do not disassemble repeatedly. Avoid applying torque force on the bellow.
