VYG series full encapsulation solid insulated vacuum circuit breakers, adopt the first full encapsulation structure and the latest solid insulating technology in the world, are in real sense solid insulated vacuum circuit breakers with high performance.
Internal structure of embedded pole is isolated from outside environment, not subject to ambient factors, such as dust, pollution, moisture or condensation, etc. The embedded pole is maintenance free. VYG series has high environmental adaptability and can run in adverse conditions.
With high performance, VYG series meet Class C2-E2-M2 requirements of Chinese National Standard GB1984-2003 and International Standard IEC62271-100, and other relevant standards.
VYG series passed a complete set of type test and other tests:
1. A complete set of type test
2. 5000m altitude test
3. Capacitor bank switching test
4. Grid performance test
VYG series has a full range of ratings and dimensions to meet different demand in industry.
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
VYG series adopts advanced solid insulating technology for outer insulation of its vacuum interrupter, making it environmentally friendly.
VYG series vacuum circuit breakers are widely used in power plants, substations, petrochemical plants, metallurgical industries, mining, manufacturing industry, airport, subway, seaport and residential areas, etc.
VYG series vacuum circuit breakers can be integrated into air insulated switchgears, a perfect replacement for the sleeve type air insulated vacuum circuit breaker.
VYG series vacuum circuit breakers can run stably under following conditions:
1. Altitude: 3000~5000m While application at 2000m and above, please specify your conditions.
2. Ambient temperature:
Daily average: ≤+35°C
Daily average RH: 95%
Monthly average RH: 90%

1. Excellent performance
2. Advanced embedding technology and solid-insulating process
3. A complete set of type test
VYG vacuum circuit breaker with embedded poles has passed a full set of type test in National High Voltage Apparatus Test Center, China.
4. Unique spring actuator
A spring actuator, compact design with less movable parts, advance face treatment process and lubricating technology, which ensure strong wear resistance and corrosion resistance, is provided to give every VYG unit an outstanding performance: rare fault, no any lubrication required in service, but great reliability and a much longer lifetime.
5. Advanced manufacture process, accurate test equipment and stringent quality policy
6. Chinese national standards & international standards
The VYG series are designed to meet all the requirements of both Chinese national standards and the international standards as follows:
7. Patented vacuum Interrupter with overall small resistance
The VYG series comprise the patented vacuum interrupter with an overall small resistance, in addition to adopting the patented contacts, characterized by high interrupting capacity, low chopping current, rapid recovery of insulation and great breaking capacity both of capacitive and inductive load.
