Instrumentation / Power and High Voltage Feedthroughs
 Catalogue Chapter as pdf-file 
Back to main menu
Power and high voltage feedthroughs are designed to carry high voltage
and/or high current in many vacuum processes. Power feedthroughs are
offered in a wide design range to match the requirements of different
applications.
The atmosphere-side ceramic surface is mostly covered with high temperature
glass coating in order to reduce surface contamination and to increase the
creep resistance.
We also offer a choice of liquid-cooled power and voltage
feedthroughs. Liquid-cooled feedthroughs are typically used with grounded,
closed cooling systems and non-conductive coolants such as deionized water
or ethylene glycol.
