What are the precautions during mounting?

Clean surfaces before mounting, ensure coaxiality of conducting pole and interrupter, avoid torque on the bellow, do not strike the envelope, and do not disassemble repeatedly to prevent screw slipping.

When should the vacuum interrupter be replaced?

It should be replaced when the burnout mark of the moving conducting pole indicates that the vacuum interrupter has finished its electrical endurance.

What are the payment terms and lead time?

Payment terms are LC or T/T. The average lead time is one month for both peak and off-season.

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 main function of the vacuum arc extinguishing chamber?

It is the core component of high voltage power switches, mainly used to cut off the arc and inhibit electric current through high internal insulation performance to avoid accidents.

Q:What materials are used in the vacuum interrupter?

It adopts a corrugated ceramic insulation shell and copper tungsten tungsten carbide alloy materials for contacts.

Q:What is the shelf life and mechanical life of the product?

The shelf life is 20 years, and the mechanical life is 30,000 times.

Q:In which industries can this vacuum interrupter be used?

It is mainly used in power transmission and distribution control systems, and can also be used in metallurgy, mine, petroleum, chemical industry, railway, broadcasting, communications, and industrial high frequency heating power distribution systems.

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

Check if packing is good, appearance matches the test certificate, and ceramic envelope is integrated. Test power frequency withstand voltage by applying 70% of rated voltage within 1 min; it is qualified if there is no sudden change or trip.
