Flexible metal bellows for vacuum sealing and electrical insulation in medium voltage interrupters
A precision-engineered flexible metal bellows component designed specifically for medium voltage vacuum interrupter modules. It provides hermetic sealing between moving and stationary parts while maintaining electrical insulation and allowing controlled axial movement during circuit breaker operation. The bellows accommodates thermal expansion, mechanical stress, and maintains vacuum integrity throughout the operational lifecycle.

The metal bellows provides hermetic sealing between moving and stationary parts while allowing controlled axial movement of contacts, maintaining vacuum integrity and electrical insulation throughout circuit breaker operations.
Stainless steel 316L offers excellent corrosion resistance, high fatigue strength for repeated flexing, low outgassing properties crucial for maintaining vacuum, and compatibility with electropolishing for clean surface finish.
Proper bellows design ensures reliable sealing throughout the operational stroke, minimizes mechanical stress on welds, provides consistent spring characteristics for contact movement, and maintains electrical clearance under all operating conditions.
