ABSTRACT:
A clad end seal for a vacuum interrupter comprises a disk-shaped base portion made of at least two clad metal layers and a cylindrical sidewall portion extending therefrom comprising one of the metal layers. The base portion provides strength and stiffness, while the sidewall portion provides stress isolation between the insulating tube of the vacuum interrupter and the base of the clad end seal. The metal sidewall has a relatively low yield strength and a thin section which reduces the risk of fracture when the end seal is brazed to the vacuum interrupter insulating tube. The clad end seal is produced by forming a clad sheet into a cup-shaped article, followed by removal of the outer metal layer from the cylindrical sidewall. The resultant clad end seal comprises a unitary component which eliminates the problems associated with conventional multi-component end seals.
