Since the beginning of 2026, the vacuum circuit breaker industry has achieved significant progress in both technological breakthroughs and market expansion, with a steady stream of innovations.
In July, XJ Electric, a subsidiary of the China Electric Equipment Group, successfully developed the VEM-12D/1250-31.5, an internal electric commutator. high-voltage, phase-controlled, hollow, with a phase control accuracy of 1 millisecond and a mechanical life of 30,000 operations, and has passed all type tests. In the same period, the 12kV and 40.5kV indoor intelligent phase-controlled vacuum circuit breakers independently developed by XD Group's electric subsidiary completed type testing and achievement appraisal, successfully establishing a complete product portfolio for medium-voltage phase-controlled circuit breakers.
In the field of testing technology, State Grid Ningxia Electric Power completed the on-site anti-re-strike performance test for a 35kV capacitor bank vacuum circuit breaker at the Jiujiu 330kV substation-the first successful on-site test of this kind in China.
Furthermore, China Southern Power Grid Guangdong Power Grid developed a 252kV single-break vacuum interrupter and circuit breaker, which have been put into demonstration application at the 220kV Fangcun substation, with zero carbon emissions over the entire product life cycle.
The market continues to grow steadily. According to a market research report, the global vacuum circuit breaker market is expected to grow from $2.96 billion in 2025 to $3.12 billion in 2026.Driven by factors such as the integration of renewable energy grids as well as the expansion and refurbishment of the electrical grid, industrial demand remains strong.
