Against the backdrop of global energy‑transition driven by the dual‑carbon goals, Wuhan Feite Electric Co., Ltd. has recently achieved a major technological breakthrough. Drawing on solid technical expertise and consistent independent innovation, the company has independently developed the 72.5kV high‑voltage vacuum interrupter, which has gained recognition and procurement orders from overseas clients. This milestone expands its product lineup beyond the original 40.5‑kV grade and enriches its product portfolio. Currently, Feite Electric boasts an annual production capacity of 660,000 vacuum switch tubes and 160,000 solid‑embedded poles, ranking among the world’s top manufacturers by output and sales volume. The newly‑launched product delivers safer, more reliable and cost‑effective core‑component solutions for the global power‑transmission‑and‑distribution sector.

With the development of the global energy internet and ongoing grid upgrading projects, higher reliability standards are imposed on high‑voltage switchgears. As the core component of vacuum circuit breakers, vacuum interrupters directly determine the safety and stability of power‑supply systems. The newly‑released 72.5kV vacuum interrupter embodies the company’s years‑long research achievements in electro‑vacuum technology. To tackle technical hurdles including hard‑to‑regulate electric‑field distribution and difficult‑current‑breaking under high‑voltage conditions, its R&D team systematically optimised contact structures, shielding cylinders and insulating housings via advanced electromagnetic‑field simulation technology. Featuring outstanding insulation performance and strong current‑breaking capacity, the product achieves compact‑size design and high dependability, meeting market demand for eco‑friendly high‑voltage switches across diverse application scenarios.

This technical leap stems from the company’s decades‑long commitment to long‑term‑oriented development. Founded by specialists with over 40‑year experience in electro‑vacuum electrical appliances, Feite Electric is a high‑tech and‑specialised‑innovative enterprise that focuses exclusively on the R&D and manufacture of vacuum interrupters since its establishment. To enter the international market, its team spent years on technical research with massive‑R&D investment, passing strict assessments by the KEMA Laboratories in the Netherlands. Its high‑quality products are now exported to the United States, the EU, Russia, South‑Korea and other regions. Driven by perseverance and pursuit of excellence, the enterprise keeps advancing from low‑voltage products toward high‑voltage and large‑current‑fields. Besides, deep‑industry‑university‑research cooperation with local universities accelerates the commercialisation of scientific‑and‑technological outcomes. It has built a strict whole‑industrial‑chain quality‑control system covering raw‑material processing to finished‑product delivery, emerging as one of the world’s most‑integrated manufacturers of vacuum switch tubes from raw‑materials to final assemblies.

The company holds nearly one hundred patents and provides full‑series products ranging from 1.14kV to 72.5kV, while conducting research on higher‑voltage and large‑current‑oriented products. According to its technical director, technological breakthrough marks merely the starting point, and large‑scale industrial‑application matters most. Building on this achievement, Feite Electric will strengthen ties with research institutes and press ahead with the development of 126kV and higher‑grade vacuum interrupters.

The launch of the 72.5kV product bears witness to Feite Electric’s upgraded technical competence. Expanding from distribution grids to main power grids and from low‑voltage to high‑voltage fields, the enterprise anchors its growth on technological innovation. Going forward, Feite Electric will leverage its professional R&D workforce and mature industrial‑experience to supply dependable vacuum‑interrupter solutions for global power grids.
