The voltage rating for for feedthroughs is determined by the length of the ceramic insulator, or the surface distance in the case of fluted designs. MPF offers 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. MPF offers power feedthroughs with current ratings to 1000 Amps.
