This circuit breaker which is independently developed by the company is a new generation of vacuum circuit-breaker. It is based on vacuum interrupter and adopts stand pole style besides with composite insulation. As a consequence, oil leak and gas leak can be solved and the breaker can be used to replace the SF6 circuit-breaker. Meanwhile, its appearance breaks the monopoly created by SF6. The product is widely used in occasions where frequent operations are needed and industries like electrical power, metallurgy, machinery and chemical.
