Category: DC Power Vacuum Feedthrough

Power is a classification given to electrical feedthroughs used to carry either high voltage or high current, or both into vacuum systems. The voltage rating for feedthroughs is determined by the length of the ceramic insulator, or the surface distance in the case of fluted designs. We offer power feedthroughs with voltage ratings up to 60,000 Volts DC. The current rating for feedthroughs is dependent on the conductor material. The choice of which must consider other factors such as strength and corrosion resistance.Copper gives the best current capacity, while stainless steel offers high strength and resistance to corrosion. Nickel, Alumel and Molybdenum are other popular conductor materials. These feedthroughs are available up to 20 pins with following fittings: welded tubing, CF, KF, ISO, NPT and Base Plate.
