High Power Feedthroughs are built to transmit extreme voltage, high current, or a combination of both in advanced vacuum applications. Using proven, time-tested designs, these feedthroughs are optimized for maximum electrical performance, durability, and safety.

Where space allows, ceramic surfaces are extended to maximize strike and creep distances. For compact environments, convoluted ceramics enhance insulation efficiency while maintaining minimal insulator length. All air-side ceramic surfaces are coated with high-temperature glass glaze, reducing surface roughness and contamination.

Most units feature exposed conductors on both the air- and vacuum-sides. Air- and vacuum-side connectors are available separately for most models unless otherwise noted.
