Frequently Asked Questions
Why use high-current hermetic ceramic feedthroughs in CO₂ lasers? How do they prevent thermal breakdown and electrical arcing?
High-power CO₂ laser power supplies generate intense thermal and electrical stresses. Standard insulators often suffer dielectric degradation or overheating under continuous heavy loads. Our hermetic feedthrough utilizes high-purity alumina ceramic brazed to a heavy-duty copper conductor, safely carrying up to 100 A. The robust ceramic-to-metal hermetic joint ensures superior electrical insulation, minimal contact resistance, and excellent heat dissipation, eliminating the risk of internal flashover or power supply failure.
Looking for a custom ceramic feedthrough manufacturer? Can flange sizes and current capacities be tailored?
Yes. As an experienced technical ceramic-to-metal assembly manufacturer, INNOVACERA provides custom-engineered feedthrough solutions. We can tailor the flange diameter (standard Ø 35 mm), flange thickness, conductor layout, mounting profiles, and upgrade current ratings beyond 100 A to ensure seamless integration into your proprietary industrial laser power supplies or vacuum chambers.
