is a commonly used sealing technology in electrical equipment, particularly in vacuum circuit breakers and other sealed devices where it is applied to the pole section. Its primary purpose is to maintain equipment reliability and stability by effectively protecting the internal vacuum environment of the pole. This ensures the normal operation of the vacuum circuit breaker under high vacuum conditions, providing high-performance breaking capacity and enhancing equipment safety and reliability. Moreover, Embedded Pole prevents corrosion, aging, and wear of internal components, resulting in a longer equipment lifespan and reduced maintenance requirements, thus playing a crucial role in ensuring the efficient and reliable operation of electrical equipment.
