The vacuum electrical feedthrough line is used to transfer low voltage (50 volts max.), high current electrical power into a vacuum atmosphere. Our feedthrough features one-piece construction, eliminating any possible leakage through weld joints. ANCORP electrical feedthroughs are constructed of oxygen-free copper (OFC) and brass. Insulator material is polytetrafluoroethylene (PTFE) for added strength and durability. A high current (1000 amp), water-cooled unit is also available.
