    VYG series 24kV embedded pole vacuum circuit breaker adopts the full encapsulation structure and the latest solid insulating technology in the world. The embedded pole of VYG series are made by special VULCANIZE process to create a cushion between the vacuum interrupter and the epoxy resin, ensuring a high reliability of the embedded poles. With high performance, VYG series passed a complete set of type tests and meet Class C2-E2-M2 requirements of Chinese National Standard GB1984-2003 and International Standard IEC62271-100, and other relevant standards. It has a full range of ratings and dimensions to meet different demand in industry. It can be integrated into air insulated switchgears (such as KYN28A, KYN96 and KYN61, etc.), universally used in applications such as power plant, substation, petrochemical plants, metallurgical industries, mining, manufacturing industry, airport, subway, seaport and residential areas, etc.
