VS1 Series Indoor Vacuum Circuit Breaker
Summary
VS1 series indoor vacuum circuit breakers are applicable to power system which power frequency is three-phase 50Hz and rated voltage range from 12kV to 40.5kV, and be widely used in industry & mining enterprises, power plant and power substation as a role for control and protect the electric equipment, also can be used in occasions need frequent operation, with high reliable performance and long mechanical endurance.
There are two types VS1 vacuum breakers when installed in switchgear, the fixed type and drawout type with chassis truck.
VS1 series vacuum breaker also offers solutions of all rated currents range from 630A up to 4000A to fully meet demands of electrical users.
Customers are required to provide relevant switchgear information for customization.
Product Model
Product features
- Provides two installation solutions: fixed type and drawout type
- Provides two models for different switchgear size: frontal type lateral type
- Provides two models for different insulation distance: VS1 VCB with insulated cylinders and VS1 VCB with embedded poles
- Encapsulated epoxy resin pole type provides higher insulation levels in less space to reduce switchgear size
- Front accessible mechanism allows for easy access to the mechanism and user friendly control components
- Adopting high quality vacuum interrupters to ensure reasonable price but superior performance
- Adoption of multi-point compressing contact process, lowering contact resistance and current carrying value hence extending breaker’s service life without maintenance
- Superior cost performance, ideal choice for engineering programs
