Metallization ceramic cylinders are a crucial component of vacuum interrupters (often referred to as VI) used in the fabrication of vacuum circuit breakers (VCB). VCBs find application in medium-voltage switchgear and distribution circuits, where they play a pivotal role in regulating distribution voltage by suppressing voltage surges.
Innovacera is a lead supplier of high purity alumina metallized ceramic cylinders. These metalized cylinders are used in vacuum arc extinguishing chambers worldwide due to their excellent electrical insulation properties
Innovacera specializes in the metallization of molybdenum-manganese (Mo-Mn) and nickel plating, providing excellent hermetic sealing for these metallzed ceramic cylinders, essential components in vacuum interrupters.
The hermetic sealing ensures the maintenance of the required vacuum level for efficient arc extinguishing within the interrupter chamber. Moreover, the high mechanical strength of Mo-Mn metallization prolongs the service life of vacuum interrupters, contributing to their reliability and durability. By offering advanced solutions in metallization techniques, Innovacera continues to play a crucial role in enhancing the performance and longevity of critical electrical infrastructure components.
Metallized ceramic cylinders provide fabrication properties and can then be easily brazed with common brazing alloys for a variety of applications.
