These electrical power feedthroughs are rated up to 1750V with use of the supplied High Current Circular Plug. Conductors are insulated with alumina and rated up to 250A. Conductors are silver plated on the atmosphere side to reduce contact resistance. The KF flanges are sealed with a centering and O-ring combination (not supplied), making them high vacuum compatible.
