Key Process Features
Metallized Ceramic Insulation
The ceramic section provides reliable electrical insulation while supporting stable operation in high-vacuum environments.
High-Current Transmission
Available current ratings of 200 A, 350 A, and 600 A support a range of vacuum power transmission applications.
Ultra-High Vacuum Sealing Performance
The electrode cores achieve a helium leak rate below 1 × 10⁻¹⁰ Pa·L/s, making them suitable for demanding vacuum systems.
High-Temperature Capability
The components are designed to withstand bake-out temperatures below 500°C, supporting vacuum chamber cleaning and high-temperature processing requirements.
Flexible Metal Joining Options
Connection to flanges or equipment can be completed by TIG welding or vacuum brazing, depending on the customer’s structure and application requirements.
