PV V&E's extensive power vacuum feedthroughs are manufactured from ultra-high vacuum-grade materials such as high alumina ceramic insulators, OFHC® copper and nickel conductors, and 304 stainless steel flanges. These robust ceramic-to-metal feedthroughs have electrical ratings for operation, with one side in a dry atmosphere while the opposite end is in a stable vacuum. They are used in ultra-high vacuum systems with CF flanges or high vacuum systems with NW flanges. Our product line comprises the most commonly required feedthroughs for general vacuum applications. Customs designs or modified standards can readily be supplied.
