Power feedthroughs are used to carry either high current, or high voltage, or both.
Large variety of electrical feedthroughs with wide range of electrical ratings to cover most requirements
Voltage ratings are conservative DC flashover with clean ceramics
Up to 600A dependant on Feedthrough
During bakeout we recommend that you do not cover the external surface of the feedthrough with foil as the aluminium can rub off onto the ceramic and cause an electrical short. It is important not to exceed the feedthrough temperature and power ratings as this can damage the feedthrough, or cause vacuum leaks.
