  • Hermetic High-Volatage Feedthroughs
Dec 2006
CeramTec North AmericaRequest Info
LAURENS, S.C., Dec. 18, 2006 -- CeramTec North America Corp. (CTNA) has launched a line of hermetic high-voltage feedthroughs that have mating air-side cable assemblies, including a 40 and 50-kV feedthrough with 10-amp current carrying capacity.

CeramTec.jpgThese high-voltage feedthroughs offer a much smaller solution to fluted high-voltage feedthrough designs, CTNA said, and have the added safety of the air-side cable assembly, which has a threaded connection.

The standard offering includes weldable, ConFlat and ISO flange-mounted installation configurations. The corona-resistant, high-voltage cable assembly, required to achieve the 40 or 50-kV rating, uses a molded silicone body and silicone-insulated cable.

The standard length for these cable assemblies is 8 ft, but custom lengths are available. The use of silicone-insulating grease is recommended for the air-side cable assembly to feedthrough interface to help assure air exclusion. High-voltage conditioning is also recommended.

Like all of CeramTec’s Ceramaseal products, these new high-voltage feedthroughs are built for use in extreme conditions. The feedthrough has a temperature capability of -269 to 450 °C and is guaranteed to be leak tight to a leak rate < 1 x 10-10 atm-cc/sec (He).
