CeramTec North America LLC. - Up to 50 Kilovolt (kV) Direct Current (DC) Voltage Rating and 10 Ampere (A) Conductor Current Rating Fluted High Voltage (HV) Feedthroughs

Products

An assembly which provides for the transfer of electrical power, gases or fluids from outside a hermetic chamber to the inside. Feedthroughs can provide both a hermetic seal and electrical isolation from the chamber wall. Feedthroughs are sometimes referred to as 'pass-throughs'.
CeramTec feedthroughs provide the solutions for applications requiring hermeticity and electrical isolation.
